When you connect to a VPN, a “tunnel” is created between your device and the VPN server. All of your internet traffic is routed through this tunnel, so your data is secure from prying eyes. But how does this tunneling process work?

Introduction to VPN Tunneling
A Virtual Private Network (VPN) is a way of using a public telecommunication network, such as the Internet, to provide private resources and user access. A VPN can connect multiple sites, over either private or public networks. The encryption of communications between VPN sites provides security and protection against eavesdropping.
Tunneling is a process of encapsulating data within another data packet. In the context of a VPN connection, tunneling allows private network traffic to be transmitted over a public network, such as the Internet.
There are two types of tunneling: layer 2 tunneling protocol (L2TP) and point-to-point tunneling protocol (PPTP). L2TP is more secure than PPTP, but both protocols provide similar functionality.
In order to set up a VPN connection, you will need to have access to a VPN server. Many VPN providers offer both L2TP and PPTP access to their servers. Once you have access to a server, you can use either L2TP or PPTP to connect to it.
L2TP uses UDP port 1701, while PPTP uses TCP port 1723. To connect to a VPN server using L2TP, you will need to use an L2TP client software program. There are many different L2TP client programs available, both free and paid. Once you have installed and configured an L2TP client program on your computer, you can use it to connect to an L2TP-enabled VPN server.
To connect to a VPN server using PPTP, you will need to use a PPTP client software program. There are many different PPTP client programs available, both free and paid. Once you have installed and configured a PPTP client program on your computer, you can use it to connect to a PPTP-enabled VPN server.
How Tunneling Is Accomplished in a VPN
Tunneling is a process of encapsulating data within another data packet. When you tunnel data, you add an extra layer of protection because the data is less likely to be tampered with or intercepted. VPNs use tunneling to protect your data as it travels across the internet.
Layer 2 Tunneling Protocol (L2TP)
Layer 2 Tunneling Protocol (L2TP) is a tunneling protocol used to support virtual private networks (VPNs) or as part of the delivery of services by ISPs. It does not provide any encryption or confidentiality by itself. Rather, it relies on an encryption protocol that it passes within the tunnel to provide privacy.
L2TP was first published in 1999 as an enhancement to PPTP. In 2005, the L2TP over IPsec standard was published by the Internet Engineering Task Force (IETF). Today, L2TP is considered more secure than PPTP because it uses stronger encryption algorithms and offers additional security features.
L2TP is typically used with the IPsec protocol to protect data transmissions over public networks such as the Internet. When used in this way, L2TP is often referred to as L2TP/IPsec (layer 2 tunneling protocol/internet protocol security).
To set up an L2TP/IPsec VPN, you will need the following:
-A router that supports L2TP/IPsec connections
-A computer or mobile device with an operating system that supports L2TP/IPsec
-An Internet connection
-The IP addresses of the VPN server and your computer or mobile device
-The preshared key for your router (this is usually provided by your ISP)
Point-to-Point Tunneling Protocol (PPTP)
Point-to-Point Tunneling Protocol (PPTP) is a method for implementing virtual private networks. PPTP uses a control channel over an IP network, as well as GRE (Generic Routing Encapsulation) to encapsulate PPP frames. PPTP has been implemented on a variety of platforms, including Windows, Linux, and iOS.
When using PPTP, a VPN client first establishes a connection to a VPN server. The VPN client then authenticates with the server and negotiates a security policy. After the security policy is negotiated, the VPN client and server use GRE to encapsulate and send data packets. Data packets that are sent over the IP network are encapsulated with a GRE header and trailer.
GRE is a tunneling protocol that can encapsulate a variety of protocols, including IP, inside of it. When using GRE, each data packet is assigned a sequence number. The VPN client or server can use this sequence number to reassemble data packets that have been split into multiple pieces.
The use of GRE allows PPTP to tunnel other protocols besides IP, such as AppleTalk orIPX/SPX . In addition, GRE can be used to tunnel multicast traffic .
Secure Socket Tunneling Protocol (SSTP)
SSTP uses a SSL/TLS connection which offers a higher level of security by encrypting all traffic going through the tunnel. To prevent tampering and ensure that only authorized users can access the network, SSTP uses both server and client authentication. This two-way authentication process ensures that only authorized users can gain access to the network and that data passing through the tunnel is not tampered with.
To set up an SSTP connection, the user first needs to obtain a SSL/TLS certificate from a trusted Certificate Authority (CA). The user then needs to install the certificate on both the client and server machines. Once the certificate is installed, the user can configure the VPN software to use SSTP as the tunneling protocol.
SSTP is only available on Windows Vista SP1 and later or Windows Server 2008 and later.
Internet Protocol Security (IPsec)
Internet Protocol security (IPsec) is a secure method of data transmittal that uses encryption and other security measures to preserve the confidentiality, integrity, and authenticity of data in transit. IPsec is often used in Virtual Private Networks (VPNs) to provide a secure connection between two or more networks, or between a network and an individual user.
Tunneling is the process of encapsulating data in one protocol so that it can be transmitted over another protocol. In tunneling, the original data packet is encapsulated in a new packet with a new header that contains instructions for how the packet should be routed. The receiving computer strips off the new header and forwards the original data packet to its destination according to the instructions in the original header.
Tunneling is a key component of IPsec because it allows data to be securely transmitted over public networks such as the Internet. Without tunneling, data would have to be sent in plain text, which would make it vulnerable to interception and tampering. By encapsulating data in an IPsec tunnel, businesses can create VPNs that allow employees to securely connect to their corporate network from anywhere in the world.
There are two main ways to accomplish tunneling with IPsec: Transport Mode and Tunnel Mode.
In Transport Mode, only the data payload is encrypted; the headers are left intact. This is typically used for communicating between two hosts, such as when an employee uses a VPN client to connect to their company’s network from their home computer.
In Tunnel Mode, both the data payload and headers are encrypted. This is typically used for creating site-to-site VPNs, where traffic from one network is routed through an encrypted tunnel to another network.
Tunneling is the process of establishing and maintaining a logical network connection (usually referred to as a “virtual” connection) between two physically separate networks. A VPN tunnel encrypts your data traffic, providing a secure connection between your device and the VPN server. Once your data reaches the VPN server, it decrypts the data and forwards it on to its destination.


SSH, which stands for Secure Shell, is a widely used network protocol that provides a secure and encrypted way to access and communicate with remote systems over an unsecured network. It allows users to securely log into and control remote servers or devices, transfer files, and execute commands remotely. SSH is a fundamental tool for system administrators, developers, and anyone who needs secure remote access to computers or network devices.
The primary purpose of SSH is to establish a secure encrypted connection between a client and a server, ensuring that data transmitted between them cannot be intercepted or tampered with by malicious actors. It replaces the less secure and plaintext-based protocols like Telnet and rlogin, which transmit data in clear text, making them vulnerable to eavesdropping and unauthorized access.
SSH provides three essential functionalities:
- Secure Remote Login: SSH enables users to log into remote servers securely, even over an untrusted network such as the internet. It uses strong encryption algorithms to protect login credentials, preventing unauthorized users from intercepting passwords or other sensitive information.
- Secure File Transfer: SSH includes utilities like SCP (Secure Copy) and SFTP (SSH File Transfer Protocol) that allow users to securely transfer files between local and remote systems. These file transfer protocols use the SSH encryption and authentication mechanisms, ensuring the confidentiality and integrity of the transferred files.
- Secure Remote Command Execution: SSH allows users to execute commands on remote systems securely. This capability is especially useful for system administrators who need to manage and administer remote servers without physically accessing them. Users can run commands on the remote server as if they were executing them locally.
SSH works based on a client-server architecture. The SSH client initiates a connection request to the SSH server. Upon successful authentication, an encrypted session is established between the client and server. This session provides a secure channel through which data can be transmitted.
The security of SSH is achieved through several key components:
- Encryption: SSH uses strong encryption algorithms to protect the confidentiality and integrity of data during transit. It encrypts all communication between the client and server, including login credentials, commands, and transferred files.
- Authentication: SSH supports various authentication methods, such as passwords, public-key cryptography, and multi-factor authentication. These mechanisms ensure that only authorized users can access the remote system.
- Key Exchange: SSH utilizes a key exchange algorithm to establish a secure connection between the client and server. This process involves generating a session key used for encryption and integrity checks during the session.
- Port Forwarding: SSH allows users to create secure tunnels between local and remote systems, forwarding network traffic through the encrypted SSH connection. This feature enables users to access services on remote servers as if they were running on the local machine, enhancing security for remote access to sensitive applications.
SSH has become the de facto standard for secure remote access and administration in the IT industry. It is supported on various operating systems and has robust implementations, such as OpenSSH, which is widely used on Linux and Unix-like systems. Additionally, many software applications and development tools utilize SSH for secure file transfers and remote command execution.
HOW TO USE AND CONFIGURE SSH IN WINDOWS ?
To use and configure SSH in Windows, you can follow these steps:
Step 1: Install an SSH Client:
- Windows does not come with a built-in SSH client, so you need to install one. One popular option is PuTTY, a free and lightweight SSH client. Download PuTTY from the official website (https://www.putty.org/) and run the installer.
Step 2: Generate SSH Keys (Optional):
- Generating SSH keys adds an extra layer of security to your SSH connections. While it’s not mandatory, it is highly recommended. PuTTYgen, which comes bundled with PuTTY, can be used to generate SSH key pairs.
- Launch PuTTYgen.
- Choose the desired key type (RSA or DSA).
- Click “Generate” to create the key pair.
- Set a passphrase to protect your private key (optional, but recommended).
- Save both the public and private keys to a secure location.
Step 3: Configure SSH Connection:
- Launch PuTTY, and you will see the PuTTY Configuration window.
- In the “Host Name (or IP address)” field, enter the IP address or hostname of the remote server you want to connect to.
- Set the connection type to “SSH”.
- In the “Port” field, enter the SSH port number (usually 22).
- Under the “Connection” section, expand the “SSH” category.
- If you generated SSH keys, click on “Auth” and browse to the private key file you saved earlier.
- Optionally, you can configure other settings like terminal appearance, proxy, etc.
- Click “Open” to initiate the SSH connection.
Step 4: Connect and Authenticate:
- If this is your first time connecting to the remote server, PuTTY will display a security warning. Click “Yes” to continue.
- PuTTY will open a terminal window and prompt you for your username. Enter your username and press “Enter”.
- Depending on the server configuration, you will be prompted for a password or passphrase. Enter the required authentication information and press “Enter”.
- If the credentials are correct, you will be successfully logged into the remote server.
Once connected, you can use the PuTTY terminal to execute commands, transfer files using SCP or SFTP, and perform other SSH-related operations.
Note: If you want to use the Windows Command Prompt (CMD) or PowerShell as an SSH client, you can install a tool called “OpenSSH for Windows” (available as an optional feature in Windows 10). Once installed, you can use the “ssh” command in CMD or PowerShell to establish SSH connections.
Remember to adhere to proper security practices, such as using strong passwords, regularly updating software, and applying appropriate firewall settings, to ensure the security of your SSH connections.
HOW TO USE AND CONFIGURE SSH IN KALI LINUX ?
SSH is pre-installed in Kali Linux, a security-focused Linux distribution. To use and configure SSH in Kali Linux, follow these steps:
Step 1: Start SSH Service:
- Open a terminal in Kali Linux.
- Run the following command to start the SSH service:
sudo service ssh start
- If the service is already running, you will see a message indicating that it is starting.
Step 2: Configure SSH:
- By default, SSH should be properly configured in Kali Linux. However, you can modify the configuration if needed.
- To configure SSH, open the SSH server configuration file in a text editor:
sudo nano /etc/ssh/sshd_config
- Make any necessary changes to the configuration file. Common configurations include changing the SSH port, enabling or disabling certain authentication methods, and modifying access controls.
- Save the changes and exit the text editor.
Step 3: Allow SSH through the Firewall:
- If you have a firewall enabled on your Kali Linux system, you need to allow SSH traffic through it.
- Run the following command to allow SSH traffic in the firewall:
sudo ufw allow ssh
Step 4: Connect to Kali Linux via SSH:
- To connect to your Kali Linux machine via SSH from another computer, you need an SSH client.
- On the remote computer, open an SSH client application (e.g., PuTTY on Windows, OpenSSH on macOS or Linux).
- In the SSH client, enter the IP address or hostname of your Kali Linux machine.
- Specify the SSH port if you modified it in the SSH server configuration (default is 22).
- Enter the username and password of your Kali Linux user account when prompted.
- If the credentials are correct, you will establish an SSH connection to your Kali Linux machine.
Remember to follow security best practices, such as using strong passwords, disabling root login (preferably use sudo), and using key-based authentication instead of passwords when possible, to enhance the security of your SSH connections.


Mid-infrared (mid-IR) lasers
Compact, high-efficiency, mid-IR laser sources in the ~3-5 µm range are exciting for a number of applications including industrial gas monitoring, chemical/bio sensors, IR countermeasures, and communications systems. Current approaches to compact mid-IR sources include type-II “W” structures, quantum cascade lasers (QCLs), and type-I quantum wells on GaSb. Type-I GaInAsSb/AlGaAsSb active regions grown on GaSb offer significant advantages over other approaches, including room temperature operation, low threshold current density, high output power, and temperature stable operation. Specifically, they feature more straightforward device design and growth than QCLs and substantially higher gain and operating temperatures than W structures.
Low-noise III-V avalanche photodetectors
Avalanche photodetectors exhibit built-in gain and can operate at high bandwidths, making them critical in fiber-optic systems, 3-D laser radar (LIDAR), sensing systems, etc. We have demonstrated the highest gain, low noise, InAs avalanche photodetectors, the first working staircase avalanche photodetector, the first quaternary alloy exhibiting low excess noise, and the first low-noise III-V avalanche photodetector operating at the standard wavelength of fiber optic communications (1.55 μm).
Epitaxial plasmonic materials
We have been actively studying the introduction of plasmonic functionality into the heart of modern photonic devices, which necessitates plasmonic materials that can be epitaxially-integrated with III-V optically-active materials (e.g. quantum wells and dots). We have achieved record high plasma frequencies for InAs:Si, the first demonstration of plasmonic response from rare earth monopnictides (e.g. ErAs), and the first demonstration of demonstration of compositional tuning of plasmonic properties (e.g. LaLuGdAs).
Metal/semiconductor nanocomposites for terahertz (THz) generation
There is currently a great need for systems to detect and identify chemical and biological agents. The 0.3-3 THz frequency range is a critical regime for such applications because of the many vibrational and rotational lines of key chemical/biological agents. The needs of such systems: high sensitivity/specificity, compact, rugged, portable, and power efficient place significant demands upon the THz sources. They must operate at room temperature and be widely tunable with narrow linewidth and high output power, electrically-driven, power-efficient, compact/rugged, and (preferably) operate cw. This requires sources that are far superior to those currently available. We are investigating new epitaxial metal/semiconductor nanocomposites to dramatically increase the performance of photomixer THz sources.
(Practical) silicon-based lasers
It has long been recognized that the integration of silicon-based electronics with photonics could be extremely powerful. This field has blossomed in recent years with the realization that on-chip interconnects are fast becoming a substantial source of power dissipation and delay. This coincides with historical progression of light as the preferred data transmitting medium on progressively smaller and smaller length scales: from ocean-to-ocean, city-to-city, ..., board-to-board, chip-to-chip, and eventually on-chip. Virtually all of the necessary optical components are in place for silicon-based optoelectronics, with the key exception being a monolithic, electrically-pumped, CMOS-compatible laser. The ultimate length scales and applications that optics will penetrate will depend on whether the silicon-laser problem can be solved, as well as its ultimate performance.
III-V transistors on silicon
The ITRS roadmap predicts serious difficulties in the coming years with simply scaling silicon CMOS. As a result, the silicon MOSFET is being virtually reinvented; high-k dielectrics are replacing SiO2 as the preferred oxide in MOSFETs. As a result, the arguments for a Si or SiGe channel become far less compelling. We are collaborating with Professors Sanjay Banerjee and Jack Lee to develop high-performance III-V MOSFETs.
Applying wireless communications approaches to optical fibers
In collaboration with Professor Sriram Vishwanath, we are studying the use of wireless signaling techniques (e.g. MIMO) to communications over conventional multimode optical fibers. Using these techniques, we have exceeded the bandwidth-length product of a conventional fiber by >15x, using only off-the-shelf-components.


Worker Safety Management System Notice Master

Product design at ARG starts with a comprehensive system functional specifications document.
Once the specifications document has been reviewed and approved, the electronics and mechanical portions of the design proceed in parallel with a very tight linkage between the two. At the same time, components selected for the project are carefully evaluated for any supply chain issues .
Prototypes – boards and mechanical components – are manufactured next. You can use your existing manufacturing shops or ARG can source the prototype fabrication for you.
Firmware and software development are the next steps (after receipt of the prototypes) followed by testing.
In some cases, testing reveals the necessity for a few design changes. If so, the process is repeated. If testing is successful, the final step is the documentation needed for manufacturing.

This paper presents a fully implantable brain machine interface based on a new CMOS system-on-a-chip (SOC) including a low-power multi-channel current-reuse analog front-end (AFE), a multi-band wireless transceiver and a power management unit retrieving power from a 13.56 MHz carrier through a new 5-coil inductive link. In addition to this SOC, the proposed interface includes a low-power microcontroller, a wideband antenna and a double-sided power recovery coil. All components are bonded on a thin flexible printed circuit board. The AFE uses a new current-reuse circuit topology based on a current-mirror opamp which is scalable to very large number of recording channels, thanks to its small implementation area and its low-power consumption. It includes a low-noise amplifier (LNA) and a programmable gain amplifier (PGA) presenting tree selectable gains of 35 dB, 43.1 dB and 49.5 dB. The SOC is fabricated in a CMOS 180-nm process and has a size of 1.3 mm × 1.8 mm. The AFE has a low-power consumption of 9 µW (4.5 µw for LNA and 4.5 µw for PGA) per channel, for an input referred noise of 3.2 µV. A 5-coil wireless power link is utilized with an efficiency of 28% and a maximum power delivered to the load of 81 mW through a 1 cm2 flexible coil. The ultra wideband edge combining BPSK transmitter reaches a maximum data rate of 800 Mbps at 6.7 pJ/bit, and the 2.4-GHz OOK receiver reaches a maximum data rate of 100 Mbps. The whole system consumes 12.3 mW and weights 0.163 g. Finally, we present biological results obtained in-vivo from the cortex of an anesthetized mouse.

Engineers in the US have invented an inexpensive printed sensor that can monitor the tread of car tyres in real time, warning drivers when the rubber meeting the road has grown dangerously thin.
“With all of the technology and sensors that are in today’s cars, it’s kind of crazy to think that there’s almost no data being gathered from the only part of the vehicle that is actually touching the road,” said Aaron Franklin, Associate Professor at Duke University in Durham, North Carolina.
“Our tyre tread sensor is the perfect marriage between high-end technology and a simple solution,” Franklin said.
In collaboration with Fetch Automotive Design Group, the researchers demonstrated a design using metallic carbon nanotubes (tiny cylinders of carbon atoms just one-billionth of a meter in diameter) that can track millimetre-scale changes in tread depth with 99 per cent accuracy.
The sensor design was detailed in IEEE Sensors Journal.
The technology relies on the well understood mechanics of how electric fields interact with metallic conductors.
The core of the sensor is formed by placing two small, electrically conductive electrodes very close to each other.
By applying an oscillating electrical voltage to one and grounding the other, an electric field forms between the electrodes.
While most of this electric field passes directly between the two electrodes, some of the field arcs between them.
When a material is placed on top of the electrodes, it interferes with this so-called “fringing field.”
By measuring this interference through the electrical response of the grounded electrode, it is possible to determine the thickness of the material covering the sensor, the researchers said.
While the sensor could be made from a variety of materials and methods, the best results were obtained by printing electrodes made of metallic carbon nanotubes on a flexible polyimide film, according to the study.

In this article we will explain the effect of aliasing, why it occurs and what can be done against it. Aliasing can occur whenever a sample rate conversion or sampling of an analog signal is performed. Great care needs to be taken to inhibit aliasing, as otherwise the resulting signal can be severely degraded.
To motivate this, let us listen to the effect of aliasing for three different kinds of signals. We take an original audio signal and perform a downsampling operation, for example to save bandwidth. Naturally, higher frequencies in the signal cannot be represented accurately with a too low sampling rate, so the downsampled audio does not sound as "bright" as the original. Despite, the effect of aliasing even impedes the audio quality. For each signal, first the original signal is presented, followed by a downsampled version that contains aliasing. Finally, the downsampled audio that has been sent through an anti-aliasing filter to prevent aliasing is provided.
A speech signal (taken from LibriVox). Here, aliasing manifests itself as some extra noise, especially around characters like 's' and 'z'.

IMSI Catcher and Selective jammer is an eavesdropping device used to intercept mobile phone’s traffic and tracking location data and mobile phone user. IMSI Catcher and Selective jammer masquerades as a mobile phone tower deviating phones within a certain radius into connecting to the device. Mentari Setia Sdn Bhd are the supplier of the IMSI Catcher device in Malaysia.
IMSI Catcher and Selective jammer use in Law enforcement
Law enforcement agencies in many multiple countries used the device to track cell phones in order to gather information or/and eavesdropping in on conversations. Some military intelligence branch used the device to intercept terrorist’s phone calls and found out the exact locations of their target.
What Does a Cell Phone Jammer Do?
The main purpose of a cell phone jammer is to stop all cell phones in the location from being able to communicate with the cell phone tower. Although the concept is simple, the methods used to achieve this are quite complicated.
Cell phone jammers work by targeting frequencies that cell phones typically use to communicate. Cell phones use different frequencies because they send and receive signals simultaneously at all times. Cell phones can also switch between frequencies to try to find the best channel for communication.
Less sophisticated cell phone jammers attempt to block cell phone signals by jamming only one frequency. Often, jamming one frequency that the cell phone uses can trick the device into believing that there is no signal. In turn, the device will not function.
More sophisticated cell phone jammers can block more than one frequency at one time. These jammers can be set to target several different frequencies that the cell phones are using, to stop both sending and receiving data. This method can also help jam signals that cell phones will attempt to switch to for a better connection as well.
More sophisticated devices, therefore, can jam cell phones on multiple networks and cut off all communication of data.
Cell Phone Jammer Uses
When it comes to the government and military, signal jammers are powerful counter tool for counter-terrorism strategies for everything from blocking radio communication to disabling explosives. Stopping criminals and offensive forces from communicating is key to thwarting their plans and ability to gather and strategize.
When it comes to civilians, signal jammers are also very useful.
Civilians that are worried about their privacy see signal jammers as a defensive tactic. Signal jammers can stop cell phones and other devices from communicating with the outside world. This can stop devices like microphones, GPS trackers, and cameras from transmitting data to malicious actors.
If a civilian is bombarded by scammer calls or needs quiet time, a cell phone jammer can stop a cell phone from receiving calls. It can help bring peace and allow you to focus on your life rather than constant phone calls.
Employers can use cell phone jammers on small and large scales. They can use them during meetings to stop employees from being distracted. Or, they can stop employees from sending and receiving communication with their cell phones during work hours.
At schools, cell phones are a major distraction. Often students will use them to cheat on tests or carry on private conversations that distract from learning. Cell phone jammers can be used by schools to stop students from using their cell phones during school hours.
Other places that rely on the quiet, such as libraries and theatres, might use cell phone jammers to stop visitors’ phones from ringing. It can also discourage people from using their phones altogether during their visit.
How it works
The IMSI Catcher tricked the targeted cell phone into believing they are the closest cell towers. Once the cell phone connects to the IMSI Catchers, the unit will act as a middle device between the cell phone and the real tower.
Mobile phones work by searching for the closest cell’s towers. The IMSI Catcher will tracked the targeted mobile phone and tricked it into identifying it as the closest cell towers. After successfully connecting to the cell phone, the IMSI Catcher device will become the middle devices between the cell phone and the tower.
Are smartphones immune to the IMSI Catcher device?
There is a belief among iPhone users that their phones are encrypted and thus they are safe from IMSI catchers. This is simply not true. Both Android and iOS devices can be tracked with ease using IMSI catchers.


NTA steps up to manage hideous wire mesh on roadside poles
Kathmandu, Sept 3: The Nepal Telecommunications Authority (NTA) has started removing the overhead cable and wire mesh cluttering the roadside poles in the Capital.
The electric, telephone wires and cables jumbled and dangling in a web like structure from the poles have contributed in disfiguring the city’s beauty. The unmanaged utility wires have also been posing security risk and contributing towards irregularities in revenue collection, Minister for Information and Communications Mohan Bahadur Basnet said as he cut down the tangled wires on a pole at Maitighar.
“The Energy Ministry is forwarding the effort to set up underground wire network with support of the Asian Development Bank and there are discussions for broadening the roads,” Minister Basnet shared.
The Information Ministry had earlier summoned the concerned authority to identify the wires but could not continue the effort to manage the hideous wires.
NTA Chairman, Digambar Jha, said the security risk posed by the jumbles of wires at a single location and the possibilities of accidents that could occur by wires getting in the way of motorbikes and vehicles necessitated the step for removing the cable and telephone wires.
The NTA plans to manage the wires for now and lay them underground in future. The authority has already allocated budget for setting up the underground wire network. RSS

The telecom industry witnessed a remarkable milestone today with the launch of Helium Mobile's Dynamic Coverage experience, a first-of-its-kind blend of nationwide network coverage and community-built Helium Mobile Network coverage. This monumental leap represents a paradigm shift in how mobile network coverage is provided and consumed.
What sets Dynamic Coverage apart from traditional network coverage is the symbiosis of multiple networks with seamless transitions between the nationwide and Helium Mobile Network coverage. This strategic integration enables Helium Mobile to offer an unprecedented experience to its users and redefine the mobile carrier industry.
Central to this transformation is the revolutionary concept of a community-built network. Helium Mobile Network's coverage is facilitated and maintained by everyday individuals who receive rewards in the form of MOBILE tokens for providing this service. This innovative approach makes Helium Mobile a true disruptor, empowering communities and individuals alike.
Despite significant strides made by the three nationwide networks in the U.S, network quality and cost remain the leading factors influencing users to switch carriers. In many areas, the high cost of infrastructure development discourages carriers from improving coverage. Enter Helium Mobile’s Dynamic Coverage, which addresses these issues by leveraging a network maintained by the community, ultimately offering improved connectivity at a lower cost.
Helium Mobile harnesses various types of wireless infrastructure, such as CBRS radios and wireless hotspots, maintained by real people. This not only lowers the cost of connectivity but also rewards those who contribute to the network. The result is a mutually beneficial system that promotes better connectivity for users and provides incentives to coverage providers.
One of the primary missions of Helium Mobile is to democratize connectivity. By offering coverage at a significantly lower cost than nationwide alternatives, Helium Mobile aims to make wireless services more accessible to a broader population, thereby changing the way connectivity is owned and managed.
The company has recently concluded an employee beta testing phase for the Dynamic Coverage experience, and with the successful activation of the rewards system, all radios on the Helium Mobile Network will now provide coverage to users and receive rewards for their service.
Implementing this breakthrough connectivity model has not been without challenges. Conventional smartphones were not designed with such an innovative connectivity model in mind. As Helium Mobile expands its roaming to all radios on the network, it expects to encounter technical hurdles. However, the company is committed to ensuring that users will seamlessly roam onto any radios in their vicinity, irrespective of the phone model.
Helium Mobile's pioneering journey is far from over. The company plans to activate Discovery Mapping later this summer. This feature will allow users to opt in to provide location data and receive rewards. The gathered data will then be used to improve the Dynamic Coverage strategy further.
The company is also developing tools to assist deployers in optimizing radio placement locations. Later this year, it will roll out the Helium Mobile Hotspot, offering a simple, cost-effective solution for more people to participate in providing coverage.
Whether you're a user, a coverage provider, or both, your participation in Helium Mobile Network signifies a bold step toward the future of mobile connectivity. This innovative move is a testament to the power of communities and the potential for technological advancements to create a better mobile carrier landscape. Together, we can shape the future of mobile.

Summit County Alert will begin operating on a new software platform September 30; residents and visitors are encouraged to create or update their accounts and notification settings
Contact:Undersheriff Joel Cochran, Summit County Sheriff’s Office970-423-8911, firstname.lastname@example.org
SUMMIT COUNTY – Summit County government is giving a major facelift to Summit County Alert, the community notification system used by local agencies to provide urgent and public-safety information to residents and visitors. Between Sept. 15 and 30, SC Alert will migrate to the CodeRED software platform, which offers more user-friendly interfaces and a more robust set of notification features and capabilities.
During the transition period, emergency messages will be sent using both the old and new systems. Beginning Oct. 1, all messaging will be delivered on the CodeRED system only.
“We’re really excited about this transition,” Summit County Emergency Management Director Rob Pearce said. “This new system is going to dramatically improve our ability to send targeted, time-critical messages to our community as well as provide mobile app options for the service.”
Local government agencies use SC Alert to send emergency notifications by phone, email and text to keep community members informed of events such as evacuation notices, utility outages, water main breaks, wildfires, floods and hazardous materials spills. SC Alert is also used to communicate non-life-safety information, such as planned road closures, utility repairs and service interruptions.
The new CodeRED platform has the benefit of providing SC Alert notifications via the free CodeRED Mobile Alert app, which can be downloaded from the iTunes Store or Google Play. And app users can even receive location-based emergency notifications from other communities when they travel outside Summit County.
“If you were up in Steamboat Springs for the weekend, and an emergency arose, you’d be able to view notifications from Routt County government,” Summit County Sheriff Jaime FitzSimons said. “And for our visitors who live in another community that utilizes CodeRED, they’ll receive SC Alert messages when they’re here.”
Users may add phone numbers, email addresses and text numbers into their CodeRED accounts, and the system is compatible with TDD/TTY devices for those with hearing impairments.
Summit County is in the process of migrating user account information from the old platform into CodeRED, but not all users are capable of being transferred, because of key technical differences between the old and new systems. So Summit County is urging all current SC Alert users to log in to the new system and create a new managed account. Current SC Alert users will receive invitation and reminder emails from CodeRED this month, beginning the week of Sept. 19.
“We understand that this transition involves a little work on the part of our current 49,204 SC Alert users, but we’re confident that CodeRED is a far better tool through which we can deliver critical information to our community,” Undersheriff Joel Cochran said. “We encourage community members to log in to the new system, make sure their info is up to date and download the mobile app. If Summit County is having a really bad day, SC Alert is among the best ways we have to get in touch with you.”
SC Alert was first launched in 2008 and has since been powered by Cooper Notification, which will soon cease providing and supporting community notification products under the Cooper brand.

PROCESSING RAW AUDIO WITH SINCNET
Modern deep neural networks can learn complex and abstract representations, that are progressively obtained by combining simpler ones. A recent trend in speech processing consists in discovering these representations starting from raw audio samples directly. Differently from standard hand-crafted features such as MFCCs or FBANK, the raw waveform can potentially help neural networks discover better and more customized representations. The high-dimensional raw inputs, however, can make training significantly more challenging. In this talk, I will discuss SincNet, a novel Convolutional Neural Network (CNN) that can efficiently process speech from audio waveforms using simple sinc filters. In contrast to standard CNNs, which learn all the elements of each filter, only low and high cutoff frequencies of band-pass filters are directly learned from data, making SincNet a very compact model that converges faster and performs better than a standard CNNs. The talk will also cover some recent improvements of SincNet and will discuss how we recently used this model for unsupervised learning of speech representations.


Want Net Neutrality in your country?
Check out the Model Network Neutrality Framework
The Model Framework on Network Neutrality was initiated by the Council of Europe and developed by the Dynamic Coalition on Network Neutrality (a multistakeholder component of the United Nations Internet Governance Forum) under the coordination of Dr. Luca Belli. You can use the Framework to propose Net Neutrality rules in your country or to improve exisiting rules. Click on each button to reveal the full text.
I. What Net Neutrality is
Network Neutrality is the principle according to which Internet traffic shall be treated equally, without discrimination, restriction or interference regardless of its sender, recipient, type or content, so that Internet users’ freedom of choice is not restricted by favouring or disfavouring the transmission of Internet traffic associated with particular content, services, applications, or devices.
II. Exceptions to Net Neutrality
In accordance with the Network Neutrality principle, Internet service providers shall refrain from discriminating, restricting, or otherwise interfering with the transmission of Internet traffic, unless such interference is strictly necessary and proportionate to:
a) give effect to a legislative provision or court order;
b) preserve the integrity and security of the network, services and the Internet users' terminal equipment;
c) prevent the transmission of unsolicited communications for direct marketing purposes to Internet users who have given their prior consent to such restrictive measures;
d) comply with an explicit request from the subscriber, provided that this request is given freely and is not incentivised by the Internet service provider or its commercial partner;
e) mitigate the effects of temporary and exceptional network congestion, primarily by means of application-agnostic measures or, when these measures do not prove efficient, by means of application-specific measures.
III. Applies to all internet services, regardless of technology
The Network Neutrality principle shall apply to all Internet access services and Internet transit services offered by ISPs, regardless of the underlying technology used to transmit signals.
IV. How to treat specialised services
The Network Neutrality principle need not apply to specialised services. Internet service providers should be allowed to offer specialised services in addition to Internet access service, provided that such offerings are not to the detriment of Internet access services, or their performance, affordability, or quality. Offerings to deliver specialised services should be provided on a non-discriminatory basis and their adoption by Internet users should be.
V. Right to a unique internet address
Subscribers of Internet access service have the right to receive and use a public and globally unique Internet address.
VI. Privacy protections
Any techniques to inspect or analyse Internet traffic shall be in accordance with privacy and data protection legislation. By default, such techniques should only examine header information. The use of any technique which inspects or analyses the content of communications should be reviewed by the relevant national data protection authority to assess compliance with the applicable privacy and data protection obligations.
Internet service providers shall provide intelligible and transparent information with regard to their traffic management practices and usage polices, notably with regard to the coexistence of Internet access service and specialised services. When network capacity is shared between Internet access services and specialised services, the criteria whereby network capacity is shared, shall be clearly stated.
The competent national regulatory authority shall:
a) be mandated to regularly monitor and report on Internet traffic management practices and usage polices, in order to ensure Network Neutrality, evaluate the potential impact of the aforementioned practices and policies on fundamental rights, ensure the provision of a sufficient quality of service and the allocation of a satisfactory level of network capacity to the Internet. Reporting should be done in an open and transparent fashion and reports shall be made freely available to the public;
b) put in place appropriate, clear, open and efficient procedures aimed at addressing Network Neutrality complaints. To this end, all Internet users shall be entitled to make use of such complaint procedures in front of the relevant authority;
c) respond to the complaints within a reasonable time and be able to use necessary measures in order to sanction the breach of the Network Neutrality principle.
This authority must have the necessary resources to undertake the aforementioned duties in a timely and effective manner.
a) The “Internet” is the publicly accessible electronic communications network of networks that use the Internet Protocol for communication with endpoints reachable, directly or through network address translation, via a globally unique Internet address.
b) The expression “Internet service provider” refers to any legal person that offers Internet access service to the public or Internet transit service to another ISP.
c) The expression “Internet access service” refers to a publicly available electronic communications service that provides connectivity to the Internet, and thereby provides the ability to the subscriber or Internet user to receive and impart data from and to the Internet, irrespective of the underlying technology used to transmit signals.
d) The expression “Internet transit service” refers to the electronic communications service that provides connectivity between Internet service providers.
e) The expression “Internet traffic” refers to any flow of data packets transmitted through the Internet, regardless of the application or device that generated it.
f) The expression “specialised services” refers to electronic communications services that are provided and operated within closed electronic communications networks using the Internet Protocol, but not being part of the Internet. The expression “closed electronic communications networks” refers to networks that rely on strict admission control.
g) The expression “application-agnostic” refers to Internet traffic management practices, measures and techniques that do not depend on the characteristics of specific applications, content, services, devices and uses.
h) The expression “subscriber” refers to the natural or legal person who has entered into an agreement with an Internet service provider to receiveInternet access service.
j) The expression “Internet user” refers to the natural or legal person who is using Internet access service, and in that capacity has the freedom to impart and receive information, and to use or offer applications and services through devices of their choice. The Internet user may be the subscriber, or any person to whom the subscriber has granted the right to use the Internet access service s/he receives. Any legal person offering content and/or applications on the Internet is also an Internet user.


- Field radiated EMI tests focus on characterising the levels of radiated electromagnetic fields emitted from the vehicle to the exterior and on the infrastructure. The magnetic and electric fields recorded are evaluated against the limits established in EN 50121-3-1 for the vehicle and in EN 50121-5 for the infrastructure.
- Track circuit compatibility test (inductive and conducted emission tests) are designed to evaluate the total harmonic content generated by the vehicle and introduced into the rail network in accordance with US UMTA-MA-06-0153-85-6/8, EN50121 and TS 50238. The recorded current signals are evaluated against the limits defined for the particular track circuits used within the project.
- Measurement of psophometric current helps evaluate the effective interference introduced by power equipment in an analogue telephone line as per EN 50121.
- Axle counter compatibility tests (inductive emission tests) are designed to assess the compatibility between the rolling stock and the axle counter detectors (EN5238 and EN50592 standards).
The magnetic fields generated by the onboard equipment are mesured by magnetic loop antennas and evaluated against specific axle counter limits.
- Exposure to magnetic fields is assessed by measuring the static and AC magnetic fields generated within the vehicle and on the infrastructure in accordance with EN 50500. These magnetic fields are then compared against European ICNIRP health and safety guidelines or other specifications.

Electrical Power that is being drawn from the use of electrical equipment such as transformers and electrical motors is known as Real Power. A building or site commonly uses considerable quantities of Reactive Power which is defined by Power that is not being drawn by electrical equipment. Real and Reactive Power together is known as Apparent Power.
Power Factor is the ratio between the two with the ideal being 1:0.
A building/site with an inefficient Power Factor tends to be the result of an inbalance between the two with Reactive Power being higher. This can be due to lost Power during the application of electrical equipment.
Having a poor Power Factor could mean your business is paying for more energy than is being used, resulting in loss of energy, money and time.
Additionally, if a building's Power Factor drops beneath a standardised ratio, then your electricity company may add Reactive Power fees to your next bill.
Power Factor Correction (PFC) technology grants the building/site manager to reduce this electricity bill by controlling the balance of Reactive Power consumption.
We use MYeBOX® technology to monitor and test your power quality. Read more below to find out how this system can save you time and money.

AWS to talk IoT at AWS Summit Sydney
“We understand that for many IoT use cases, IoT data needs to be collected, processed and actioned at the edge – where the customer’s business runs,” he told IoT Hub.
“To reflect that, we will be showcasing the capabilities of AWS Greengrass in delivering IoT edge intelligence with integration to other services such as Amazon Rekognition and AWS Machine Learning solutions.”
AWS Greengrass, Hickin explained, is software to run local compute, messaging, data caching, sync, and machine learning inference capabilities for connected devices in a secure way.
“With AWS Greengrass, connected devices can run AWS Lambda functions, keep device data in sync, and communicate with other devices securely – even when not connected to the Internet,” he said.
“Using AWS Lambda, AWS Greengrass ensures your IoT devices can respond quickly to local events, use Lambda functions running on AWS Greengrass Core to interact with local resources, operate with intermittent connections, stay updated with over the air updates, and minimise the cost of transmitting IoT data to the cloud.”
A new feature, AWS Greengrass ML Inference, brings machine learning services to the edge. “It lets application developers add machine learning models to their devices and edge hardware so that complex machine learned models (prediction, classification etc) can be run and executed on the edge – close to the data,” Hickin said.
