Most field service organisations offer scheduled maintenance as part of their servicing contracts. Regular, routine maintenance helps ensure equipment and systems remain continuously operational, minimising downtime and reactive call-outs to fix faults. Many service providing companies are now striving to optimise their field service operations by using data and system insights to help in their quest to keep their client’s equipment running smoothly. In this post we look at how the Internet of Things (IoT) is enabling this whole new approach to field service.
What is Connected Field Service?
The Internet of Things (IoT) refers to the increased internet connectivity of all manner of devices. Cheap, small computer chips in conjunction with widely available wireless networks allow devices to share data and carry out automated actions when required. For example, a smart thermostat might detect a lower temperature in one area of a building and this information is then used by an intelligent heating system to turn up the heat in that specific room.
Connected field service refers to the use of sensors on monitored equipment, connected directly with field service management software, enabling the identification and diagnosis of issues before they become problematic. Real-time device monitoring goes way beyond routine service maintenance operations, providing immediate insight into system behaviour and performance. Adding internet connected sensors to monitored systems introduces a whole new level of digital intelligence, allowing connected systems to automatically communicate without the need for human involvement.
Differences Between Field Service and Connected Field Service
Traditionally, field service is involved in the installation and commissioning of new equipment and systems which are then maintained based on routine maintenance schedules. These would involve regular site visits to run through a number of system diagnostic checks and sometimes the replacement of certain parts that might be wearing out or need updating. If a piece of equipment breaks down or begins to perform badly then a reactive service visit is required to fix the problem.
But the absence of sensors to detect when a system is malfunctioning or operating outside of acceptable parameters means that early warning signs can be completely missed which may then result in disastrous and costly system failure.
In a connected field service context, system sensors monitor specific parameters and aspects of system performance. When any of these stray outside of defined limits then automated alerts prompt attention from the service providing organisation before a disastrous system failure occurs.
Benefits of Connected Field Service
This brief description of how connected field service works, using sensors, the Internet of Things (IoT) and centralised field service management software, demonstrates how beneficial this approach can be for both system owners and service providers. Here are just some of the key advantages provided by connected field service.
1. Lower Maintenance Costs
Monitoring systems in real time means that issues can be detected and resolved before they get worse and possibly cause disastrous and expensive system failure. Remote system monitoring reduces the need for routine maintenance visits to check on system performance and the frequency of call-outs to deal with system faults is enormously reduced. Maintenance costs are therefore significantly lower when connected field service is implemented.
2. Reduced System Downtime
Downtime, wherein systems are completely out of action while awaiting and undergoing repair, is significantly reduced by employing connected field service. Field service organisations can be alerted to imminent system failure warning signs even before a customer is aware there is a developing issue.
3. Faster Repair Times
Data derived from system sensors provides what’s required to dispatch the right technicians and engineers, who have the necessary skills and experience, to a customer’s site. This detailed system insight also enables intelligent decisions to be made regarding spare parts that might be needed. This all contributes toward faster repair times and improving the first-time fix rate.
Enhanced Customer Satisfaction
It is widely recognised that first-time fix rate contributes toward high customer satisfaction ratings. And an effective, connected field service process will further enhance customer satisfaction.
Maximised Upselling and Cross-selling Opportunities
Connected field service provides valuable insight into how customers use their systems and equipment. This insight can present many upselling and cross selling opportunities.

I. Introduction - What is GPS
The Global Positioning System, or GPS, is a satellite based navigation system developed by the United States Defense Department in the 1970's. It provides three items to users:
This is often abbreviated as PVT (Position/Velocity/Time). The system typically is delivering under 10 meter accuracy of position, under 10 cm/s velocities, and under 0.1 microsecond of time today to all users, military and civilian, to anyone with a $100 receiver.
At the simplest level, it does this by having the antenna of a specialized radio receiver, a GPS receiver, open to the sky so that it can receive signals from 4 or more satellites. There are 28 active satellites in early 2003. The nominal constellation has 24 satellites, and the minimal system has 21.
The satellites are in high orbit at about 20,000 km above the earth in 6 orbital planes. They orbit the earth with a period of 12 hours. (This is 12 hours sidereal time.) The ground tracks repeat every day. This system ensures that more than 4 satellites are available everywhere on the earth at all times. This is a everywhere / anytime system.
The generic navigation situation is shown above. The satellites broadcast signals that are received by the user. In this case a ship is shown. It could just as easily have been a truck, airplane, missile, surveyor, hiker, a bank ATM machine or many other types of users. The system is free to anyone with a GPS receiver. The number and type of users has grown over the two decades since the system as been operational. Currently the estimate is that there are over 5 billion dollars in annual sales of GPS equipment to civilian users. This is several times the military sales.
If GPS went away, it would cause major problems to both the military and civilian users. In a study conducted in 2000, it was shown that the most critical effects would come not from the loss of positions of velocities but from the loss of very accurate timing. The time accuracy available with GPS is under 1 microsecond. (In fact the error is usually on the order of 10 nanoseconds, although the specification is much higher.) This accuracy is over 3 orders of magnitude better than any other inexpensive methods. We have come to depend on synchronized time at remote locations for ATM's (encryption ), the power grid, and many other applications.
II. GPS Signals and PVT
The satellites broadcast a complex signal. It can be understood
as providing three effective signals, a carrier signal (sine
wave), a series of pulses, and some binary information modulated
on the signal. These are the "effective" signals seen in a
receiver after some signal processing. The details will be left
to engineering texts. (For those who want to know, the signals
are bi-phase modulated with two sequences of binary bits, on a
suppressed carrier signal. There is no carrier - why put energy
where it is not needed - and no pulses. The pulses and carrier
are generated in the receivers.)
A diagram of the effective signals used by a GPS receiver is shown above. The signal generally used for navigation is a series of reconstructed pulses. These are tagged or labeled with the time of transmission by the satellites. The receiver notes the time that the pulse is received. The difference in time, multiplied by the speed of light, is the range to the satellite. GPS is a time of flight, pulsed timing system. It determines ranges using time of flight of effective pulses.
Of course there are many complications. The major one is that the receiver is using its own clock to tag the received time. This is often supplied by a very inexpensive crystal oscillator. The speed of light is about 0.3 meter per nanosecond ( about a foot per nanosecond). Thus very small errors in the receiver's clock can cause large range errors. This is solved by including the time bias of the receiver clock in the set of unknowns. Therefore there are 4 unknowns at each timeline where a solution is computed, 3 for position and 1 for time. This is why the minimum number of satellites for a solution is 4. It is also why the receiver can provide such good time. At each timeline, usually once per second, a new estimate of accurate time (GPS time) is generated in every receiver.
The second signal is the carrier wave. This is generally used to determine the velocity of the user. The frequency of the received signal will change if the receiver is moving. This is the Doppler shift. By measuring the Doppler frequency on at least 4 satellite signals, the three dimensional velocity and the frequency offset of the receiver's oscillator are found.
There are several issues that need to be considered in finding the position, velocity and time of the user from these measurements. The ranges are not useful in finding a position if you do not know the location of the other end of the range vector. The location of the satellites is needed. Telling the user about the location, velocity, and clock state of the satellite is the purpose of the third signal, the message data. This is a low rate binary signal at 50 bits per second. It provides a series of numbers that are used in a fixed set of equations (a model) to determine the satellites Position, Velocity, and Time. This information is divided into two pieces, called the Broadcast Ephemeris (BCE) and the Almanac.
It takes a maximum of 3 minutes tracking to get the BCE from a satellite. This data repeats every 3 minutes. The data from a satellite cannot be used for generating a solution until the BCE is completely received. The BCE changes very slowly, a new version is available once per hour. The BCE provides information on the satellite position and velocity, which is very accurate and stays that way for a day or so. The BCE also provides information about the bias of the satellites onboard clock. The satellites have an atomic clock, but it wanders a few nanoseconds per day. The inaccuracy in the clock parameters in the BCE are a major error source.
The message data from each satellite includes the high accuracy numbers for its own PVT. In order to help receivers plan satellite tracking an acquire satellites signals, a lower accuracy set of numbers is provided for all the satellites in orbit. This is called the Almanac. It cycles more slowly and takes 12.5 minutes to repeat. This data is updated weekly. Usually all satellites broadcast the same almanac. The almanac also contains some other parameters. Among these are the values needed to convert the GPS Time used by the satellites to Universal Time Coordinated (UTC).
III. Measurements to Positions
The GPS receiver can be though of as having 3 functional units:
These are shown on the diagram below.
In the early days of GPS receivers, the noise in the front end was an important factor in the solution errors. Today the errors in the BCE are often dominate. In some cases where there is a lot of metal near the antenna, the measurement errors are still important. This is called multipath.
The navigation module usually has a type of solution called a Kalman filter. This solution tries to keep a model of the receiver motion and solves for the difference between the predicted PVT and the values most consistent with the measurements. It forms a solution using weights for the new measurements and the past model. These weights are used to "forget" the data from the distant past that may not be relevant to the current position. (A ship, airplane or other vehicle is subject to unknown forces and the actions of the pilot.) These weights are often determined dynamically to adjust for the current receiver conditions. At turn on the solution often assumes it knows nothing but adjusts the weights to favor the model as it learns more.
One important distinction is between Measurement Space and Solution Space. There are different quality values published about the GPS satellites and the GPS system. Because the mapping between measurements and solutions takes place in every individual receiver, the GPS system quality values tend to be stated in terms of measurements - that is in measurement space. To the user, however, the errors in solutions are most important.
There is a very useful rule of thumb about the mapping between measurement errors and solution errors. This is stated in terms of a value called Dilution of Precision or DOP. The general rule is:
Dilution of Precision is always greater than 1. In using this you get a single value to quantify the solution error and must use some averaged measurement error.
DOP vary because the satellites are at different positions in the sky at different times. If all the satellites used in a solution are along a north-south line you have very good information on the north- south position, but poor information on east-west position. The DOP is a function of the geometry of the satellites used in the solution. If the satellites are well spread out in the sky, the DOP will be low. If the satellites are clustered, it will be high. (There are other conditions for high DOP that are harder to intuitively understand. After all the solution is done in a four dimensional space.)
There are several version of DOP's. The total solution, including the time has value called Geometric Dilution of Precision or GDOP. The position only case is called PDOP for Position Dilution of Precision. For the surface user, only horizontal position is usually important. This error is related to the average measurement error via HDOP. And there is also a time or TDOP.
IV. GPS Service Levels: Codes and Frequencies
There are two levels of service provided, the Standard Positioning Service (SPS) and the Precise Positioning Service (PPS). The PPS is defined as that functionality that needs encryption data and the SPS as any use that needs no encrypted data. In general this means the SPS is the civilian service and the PPS is the military service.
There is hardware on the satellites to provide two aspects that distinguish the two services, the Anti-Spoofing or AS function and the Selectivity Availability or SA function. The SA function degraded the accuracy of the solutions to a standalone user. It was essentially negated by Differential GPS. SA was turned off by presidential order in May 2000. It is unlikely to ever return.
Anti-Spoofing is designed to prevent an adversary from generating a signal that will be mistaken for a valid satellite signal. There are two different navigation codes used for generating the effective pulses, the CA or clear/acquisition code and the P/Y or precision code. The CA and P codes are public knowledge. The signal that is the P-code is encrypted by the AS function before it is transmitted. It is then re-labeled as the Y-code. The military uses receivers that accept cryptographic keys that allow the use of the Y-code. (These keys were also used to remove the SA effects.) By using only the Y-code in a conflict situation the possibility of spoofing a military receiver is essentially zero. There are other things an adversary can do however, such as jamming.
There are two frequencies broadcast by the GPS satellites. These are called the L1 at 1575 MHz and L2 at 1227 MHz. The L1 signal is thought of as the measurement signal. This measurement goes through the ionosphere, a region between about 100 and 1000 km above the earth. Passage through the ionosphere adds a systematic error to the ranges. However this error can be removed to the millimeter level using the L2 signal. This is the primary function of the L2 signal. The P/Y codes are on both frequencies. The CA , or civilian, signal is only on L1. Therefore civilian users would normally be effected by the ionospheric error.
The use of DGPS effectively illuminates this error over a significant area, out to 50 to 500 km depending of many factors. In addition the civilian receiver manufactures have developed several methods of tracing the L2 signal despite it being encrypted. (This does not affect the anti-spoofing value of the encryption so the military is not worried about this development.) This L2 tracking was previously available only on expensive receivers used for survey and other precision applications. It is becoming available on more inexpensive receivers now.
As part of the agreement that lead to the termination of the SA function, newer satellites will have a new broadcast frequency called L5. This signal is principally intended to remove the ionospheric error for the civilians. It will have an unencrypted range code.
The L2, and now L5, signals have been used for more than ionospheric corrections from the beginning. These are mainly for high accuracy applications. This will continue.
It is conventional to discuss the overall GPS system as being broken into three segments:
The control segment is the key to accuracy of the solution to a non-differential user. This occurs thorough the generation of the Broadcast Ephemeris. The Control Segment consists of 5 sties spread around the world. These sites have two functions. They have high quality PPS receivers that acquire data. Instead of being used to compute the position of the sites, the raw data is transmitted to a central site in Colorado Springs. This data is used to compute the new BCE's. These sites also have upload antennas that are used to send the BCE's to the satellites. The satellites just read the message data from an internal memory. All the computation is done on the ground and the bits transmitted sent in the uploads to the satellites.
VI. System Control and Administration.
The GPS system was begun in the early 1970's with the formation
of a Joint Program Office (the GPS-JPO) to oversea the
development of a joint services navigation system. It was the
merger of Air Force and Navy systems then being planned. The
management has evolved from a JPO to a multiple cabinet level
executive committee. The Air Force remains the lead agency and
the executive agent. The major players are now the
Position/Navigation committees of the Department of Defense and
Department of Transportation.
The structure is outlined in the figure above.
The Interagency GPS Executive Board (IGEB) has two co-chair members and several other members. The DoD and DoT are the ch-chairs. The departments of Commerce, Interior, State, Justice and Agriculture are also members as well as NASA and the Joint Chiefs of Staff of the DoD. The Air Force is the executive agent. It's efforts are all under a major US Air Force Command (formally the US Space Command before it was merged). The two major USAF players deal with daily operations and development. The Consolidated Satellite Operations Command Center (CSOC) is where the GPS day to day operations occur. The Second Operations Squadron (2OPS) at the CSOC handles GPS. All development and procurement of hardware and the management of software development is done by the GPS-JPO which is part of the Space and Missile Command (SMC) at Los Angeles Air Force Base.
The civilian inputs are channeled through a committee that has frequent public meetings. This is the Civilian GPS Service Interface Committee (CGSIC) . The US Coast Guard (USCG) serves as the agent that provides support to the CGSIC. Most civilian interface to the GPS system first occurs with the Coast Guard. They have a Navigation Center just outside Washington that provides an internet site for this purpose. ( www.navcen.uscg.gov ) . This site has current status of the satellites and the system as a whole, most public GPS documents and specifications as well as some forms for submitting comments or trouble reports. The minutes and agenda of the CGSIC are located at this Internet site.

eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 162.xx.xxx.xxx netmask 255.255.240.0 broadcast 162.xx.xxx.xxx inet6 xxxx::xxxx:xxx:xxxx:xxxx prefixlen 64 scopeid 0x20<link> ether xx:xx:xx:xx:xx:xx txqueuelen 1000 (Ethernet) RX packets 3620568 bytes 362006705 (362.0 MB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 4207132 bytes 15241705653 (15.2 GB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 eth1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 10.xxx.xxx.xxx netmask 255.255.0.0 broadcast 10.xxx.xxx.xxx inet6 xxxx::xxxx:xxxx:xxxx:xxxx prefixlen 64 scopeid 0x20<link> ether xx:xx:xx:xx:xx:xx txqueuelen 1000 (Ethernet) RX packets 10596 bytes 19622652 (19.6 MB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 10422 bytes 105107712 (105.1 MB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10<host> loop txqueuelen 1000 (Local Loopback) RX packets 3334690 bytes 2170366969 (2.1 GB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 3334690 bytes 2170366969 (2.1 GB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
This output shows us which adaptor is the external connection and which the internal: the inet address of eth1 starts with a 10 meaning it's internal. And I happen to know the public facing interface of this particular server has an inet address starting 162. So now we can configure ufw appropriately.
Run the following command at the terminal:
sudo ufw allow in on eth0 from [IP addr you are connecting from] to any port 22
Check the rule has been added by running:
sudo ufw status
Now add a rule allowing connections to and from the VPC:
sudo ufw allow in on eth1 to any port 22
Again check the ufw status to ensure your rules have been added.
If it's SSH you are configuring then it's worth ensuring you can still SSH on to your server before closing the terminal you are currently working from. If all is working then your server is now configured.

The new iPhone 14 and iPhone 14 Pro have a ton of new features, including Crash Detection, excellent battery life, and the Dynamic Island, but there’s one feature that hasn’t arrived yet: Emergency SOS via satellite. But it won’t be missing for much longer.
In a press release touting the technology and infrastructure behind the feature, Apple confirms that Emergency SOS via satellite will be arriving “later this month” for customers in the U.S. and Canada. It’s not clear whether it will coincide with the launch of iOS 16.2 or arrive via a separate update.
Apple developed the service in partnership with Globalstar with an investment of $450 million to provide the “critical infrastructure” for the new feature. As Apple explains, Emergency SOS via satellite uses the spectrum in L and S bands designated for mobile satellite services by ITU Radio Regulations. Here’s how it works:
When an iPhone user makes an Emergency SOS via satellite request, the message is received by one of Globalstar’s 24 satellites in low-earth orbit traveling at speeds of approximately 16,000 mph. The satellite then sends the message down to custom ground stations located at key points all over the world.
When a message is received, it’s then routed to emergency services or a relay center with Apple-trained emergency specialists if the closest location is unable to receive texts.
Globalstar executive chairman Jay Monroe calls Emergency SOS via satellite a “generational advancement in satellite communications” thanks to new high-power antennas designed and manufactured specifically for Apple that were installed in all Globalstar worldwide ground stations.
The feature will be free for at least two years for all iPhone 14 users in the U.S. and Canada, including Puerto Rico and the U.S. Virgin Islands. However, Apple says Emergency SOS via satellite isn’t available in Guam or American Samoa, and might not work in places above 62 degrees latitude, such as northern parts of Canada and Alaska.

Invasive cyber attacks on data centers cost billions of dollars, but can be mitigated by sophisticated software and hardware-based security defenses. However, a physical attack on machines in a data center using various fault injection methods can cause damage without compromising security. Therefore, Intel developed the Tunable Replica Circuit (TRC) telemetry control technology supported by the 12th generation core Alder Lake platform to detect similar attacks.
“Software protections have been strengthened through virtualization, layered canaries and code verification,” said Daniel Nemiroff, Intel’s principal engineer. “This has led malicious actors to turn their attention to physical attack computer platforms. A favorite tool of these attackers is fault injection attacks with flash voltages, clock pins and electromagnetic radiation that cause circuit timing errors and allow them to execute malicious instructions and potentially flash secrets.”
Intel’s Alder Lake 600-series chipsets (which Intel calls the Platform Control Hub, or PCH) have a TRC module that constantly monitors the operation of other components in the system, including the CPU, which supports the company’s Converged Security and Management Engine (CSME). himself.
TRC monitors timing failures due to voltage, clock, temperature, or electromagnetic malfunctions, which can be caused by a variety of factors. For example, when certain CPU times are out of the ordinary, this could indicate a cyber attack (using a malicious command or exploiting holes in security). A set of TRC sensors are tuned to detect errors caused by fault injection rather than normal workload voltage drops, so Intel is confident that the technology won’t use mitigation techniques to ensure data integrity under normal conditions due to false positives.
“The circuit is optimized for security applications by changing the monitoring configuration and building infrastructure to increase the TRC’s vulnerability to false injection attacks,” said Carlos Tokunaga, principal engineer at Intel Labs.
While TRC technology is being tested on client platforms, it could also find its way into Intel’s upcoming data center platforms. For obvious reasons, it is very difficult to physically enter a data center to access a PC. But once a criminal is in, TRC can be very useful as it can access multiple systems at once.

Multi-source multi-destination (MSMD) wireless model is developed for wireless devices to share the limited spectrum resource in the same communication channel, which induces the mutual interference with each other. To reduce or even cancel the mutual interference in MSMD network, various techniques were proposed in literatures, including beamforming design for multi-user multi-input multi-output (MIMO) channels and cooperative relaying strategy. In addition, power control is a critical issue as the performance at each destination depends not only on power allocation of its corresponding source, but also on the power allocation of other sources. An optimal power control strategy helps to manage the interference between each pair of source-destination, thus further improves the overall system performance. Hence a design to optimize power allocation to efficiently apply the MIMO techniques and cooperative relaying protocol becomes more attractive for MSMD networks.
In this dissertation, we analyze the performance improvement and develop optimal power allocation strategy for MSMD MIMO and relaying network based on optimize methodology, approximation theory and game theory. We aim to develop optimal strategies with low complexity for power allocation in MSMD network by considering two optimization models. (1) Power minimization subject to Quality of Service (QoS) constraints, including Signal to Noise plus Interference Ratio (SINR) and outage probability. (2) QoS maximization subject to power constraints.
First, we develop an optimal transceiver beamforming strategy to minimize the total power of sources subject to SINR constraints for a MSMD network where MIMO technique is applied in both sources and destination. We propose a distributed algorithm to find a Nash optimal solution and provide a necessary condition and a sufficient condition to the existence and the uniqueness of Nash optimal solution. We show that the probability of convergence of the proposed algorithm is higher than earlier work.
Though Nash optimal solution is easy to obtain in practical, yet it is not efficient in terms of overall power consumption. Thus we further develop a more efficient algorithm for transceiver beamforming design for MSMD MIMO network with pricing consideration in order to find a Pareto optimal solution, which is more efficient than Nash solution in terms of overall power efficiency. We also compare the proposed algorithm over another two alternatives to show our advantage. In convergence analysis, we provide a sufficient and a necessary condition to the convergence of the algorithm. Different from most of earlier related work, where only single antenna at destination was considered, our transceiver design is also applicable to the scenario where multi-antennas are deployed in each destination.
MIMO beamforming technology does open an avenue for us to improve the performance of MSMD network. However, due to space and cost limitation, MIMO technique might not be available in some applications. As an alternative, cooperative relaying is a promising technologies to improve the performance of MSMD network. To discuss the optimal power allocation strategies in MSMD relaying network, we start from the optimal power allocation design in a single-source single-destination relay network with Differential Amplify-and-Forward (DAF) protocol. With our simple approximation of outage probability for a DAF scheme, we are able to propose a simple solution to optimize the power allocation, which is a tight approximation to the accurate optimal power allocation verified by our numerical results. In addition, we also provide an optimal relay location design and joint power and relay location strategy for a DAF relaying protocol to further improve the overall system performance.
Differing from the single-source single-destination relay network, the performance analysis for MSMD relay network is more complicated due to the effect of the generated interference between each pair of users. By considering the SINR and its approximation of each user, we are able to develop an optimal power allocation strategy for MSMD relaying network to guarantee the minimal SINR of each user is satisfied. With an approximation of SINR representation, we propose low complexity algorithms to optimize the power assignment for MSMD relaying network, where two scenarios are investigated, minimization of total power subject to SINR constraints and maximization of minimal SINR subject to total power constraint. The results obtained by the proposed algorithms are shown to be very close to those obtained by exhaustive search, while the former outperforms the latter in terms of very low computation complexity.

TrueSpeed has secured £75 Million from Aviva Investors to build an Ultrafast Full Fibre Network in the Chew Valley and the wider South West area.
Aviva Investors, the global asset management business of Aviva plc (‘Aviva’), has committed £75 million to support Newton St Low based TrueSpeed Communications Limited ultrafast full fibre broadband network roll out across South West England.
Established in 2015 to deliver a fibre-optic infrastructure network across South West England, TrueSpeed provides residential and commercial customers with multi-gigabit capable symmetrical speeds through a full fibre network. TrueSpeed already provides this service to homes connected to its fibre-to-the-premises (FTTP) network in several Chew Valley villages including Compton Dando, Woollard and Burnett, and the company say it is transforming the way people live and work in rural communities.
The partnership with Aviva Investors allows TrueSpeed to accelerate its expansion strategy to pass up to 75,000 homes and businesses in the region.
Ian Berry, Head of Infrastructure Equity, Aviva Investors said he was delighted that Aviva could help TrueSpeed deliver their service to a wider area.
“This is another example of how we work to support the delivery of essential infrastructure in the UK, while also providing our institutional investor clients with access to long-dated income streams to help ensure the payment of pensions potentially decades into the future,” said Mr Berry.
Sean McLachlan, Senior Director, Infrastructure Equity, Aviva Investors explained that their investment would allow TrueSpeed to ’accelerate its business plan’ seeing this Chew Valley born company launched just two years ago expand from a demand-led
service to one that can ’provide world class infrastructure to users who are currently underserved.’
TrueSpeed CEO, Evan Wienburg said the investment from Aviva was ’brilliant news’ for local residents and businesses as it would allow more people to benefit from the high speed services they offer.
“This brand new infrastructure will be capable of handling the speed requirements of our customers now and in the future at a competitive price and with a regional service focus," said Mr Wienburg. "My whole team is very much looking forward to working with Aviva Investors and delivering some of the fastest and most reliable internet found anywhere in the world. Fast, Fair, Forever!”


In the 1999 fall beamtime the DSC CsI readout was tested. We found an indication for crosstalk on our ADC channels, which we have used as DSC input.
On the other hand the UVa splitter output is terminated with 50 Ohms; the twisted pair cable impedance is 100 Ohm (as the differential input termination of the ADC). This may cause reflections on these channels.
After our 1999 beamtime a first raw test was made by the input of a NIM pulse of one channel of the twisted pair cable and measuring its crosstalk on the neighbour channels. We could measure up to 15 percent of the original amplitude on the neighbour channels (analog scope, ground connection to the NIM pulser crate). The same test we have made with a sine signal (variation of frequency). Some crosstalk was measureable over the whole cable (8th neighbour). A big portion of this crosstalk was due to the use of the 'spy cards', which we use to split ECL signals. On the other hand we could see a huge noise on all channels.
The crosstalk was measured again without the use of the spy cards with an original CsI signal from channel CsI_02 (all other CsI high voltages are off). Figure 1 and 2 show scope hardcopies of the signals, channel 1 with the original signal, channel 2 shows crosstalk and noise on the neighbur channel. For figuure 1 a twisted pair cable is used, for picture 2 coaxial cables (RG174/U) with the same connector type with flat ribbon cable header.
Figure 1: Crosstalk measurement with twisted pair cables
Figure 2: Crosstalk measurement with coaxial cables
The lower noise and lower crosstalk with 50 Ohm coaxial cables is also visible in our ADC spectra. For this mode a small modification on the ADC board is necessary. Then the ADC operates in 50 Ohm mode for coaxial cables instead of quasi differential input.
Figure 3 and 4 show the ADC spectra for CsI channel 2 with Cosmics. There is no significant difference between the two operation modes of the ADC.
Figure 3: ADC Cosmic spectrum with twisted pair cables
Figure 4: ADC Cosmic spectrum with coaxial cables
By the use of coaxial cables we can reduce the noise by about a factor of 2. Figures 5 and 6 show the noise peaks with twisted pair cables and with coaxial cables.
Figure 5: ADC pedestal peak with twisted pair cables
Figure 6: ADC pedestal peak with coaxial cables
Taking a look on the 2-dimensional Spectrum (Figure 7,8, CsI number versus ADC channels) it is obvious, that there is less noise on more or less all channels. There is more noise on these channels and maybe crosstalk over more or less all channels, because the twisted pair cables are packed very tight.

It’s not just about enhancing your telephone canvassing scripts when it comes to rethinking your communication strategies and strategy. Consider the advantages of a VoIP system for your online business if you still utilize a landline number. Change is fueled by factors such as speed, dependability, and cost savings.
What is VoIP, and how does it work?
VoIP (Voice over Internet Protocol) is a popular modern business telephone system that replaces traditional landlines. Its name stands for “Voice over Internet Protocol,” but what precisely does that imply? Simply described, they are audio calls that occur between two online phone systems. Users can communicate with one another over the internet from anywhere in the world.
Within the dialing program, there is a VoIP solution.
What are the advantages of using a VoIP system for your company?
VoIP telecommunications, which is simple to use and available with a simple Internet connection, has a number of advantages for your organization.
Increase your mobility and flexibility.
With a virtual phone system, you’ll be able to take calls from anywhere! There is no reason to use a desk phone that is connected to a landline. However, if you prefer, you can do so. You can reroute calls to your own mobile or landline, as well as receive and make calls from a desktop or laptop computer. This gives you the freedom to work from home or remotely.
Using VoIP technology, as well as video conferencing technologies, avoided a large work stoppage during the COVID-19 pandemic. While many firms have been forced to close their doors, e-commerce sites that use VoIP technology have been able to simply adjust to teams working from different locations.
Introduce technology that is smoothly integrated.
VoIP can coordinate your entire organization, linking to other cloud-based technologies, in a world where client interaction is critical.
Synchronized communication has the advantage of allowing real-time engagement over asynchronous communication. The benefits of synchronized communication include immediate feedback and explanation.
Retailers must be consistent across a wider range of communication channels. When connecting with businesses online via a range of digital devices and platforms, customers want personalized and consistent experiences.
Create a consumer experience that is both individualized and integrated.
In 2021, the holy grail of communication will be creating a seamless and integrated consumer experience. If your clients connect with your company in a variety of ways, providing a consistent and tailored experience is critical.
A consumer, for example, can start a conversation with your staff by sending a message on Twitter. He will then anticipate being able to take advantage of a phone conversation to further explore the matter without having to explain himself.
VoIP allows CRM and other applications to be integrated, making it feasible to respond to client demands more swiftly for retention purposes. Employees across the firm have access to the data, which allows them to fix issues much faster than if they had to fill out many customer support tickets.
Workflow should be optimized.
The use of VoIP platforms also helps teams function more efficiently. Some processes that formerly needed multiple steps can now be completed with only one click.
Teams can work smarter and quicker when they employ VoIP technology. Efficiency and productivity are greatly increased since call center operators can instantly access information through the connected CRM system. The capacity for management to listen in on calls; the option to record calls so that critical points are not forgotten; and the ability to put callers on hold temporarily are just a few of the advantages that your team’s workflow may reap.
Expand your e-commerce business.
E-commerce companies must be able to communicate with customers all over the world. This can be prohibitively expensive with a standard landline. More and more businesses are realizing the cost and reliability benefits of VoIP functions. Moving your corporate communications to the cloud can aid in the support of a remote workforce, the strengthening of your call center, and the improvement of customer happiness. Some of the best things that you will know about the online phone system are that it has a good attendant system too. With the online phone system, you can transfer the calls to the right executive and department in the office.

AWS networking is probably the most important thing that people don’t want to think about. While networking on the cloud is similar to traditional on-premise, there are a few key differences. Here’s a few terms that people may or may not be familiar with:
VPC – Stands for virtual private cloud. Essentially it’s a managed network, all your network resources must live in a VPC. You can have multiple VPCs per account and even have them talk with one another (so long as the IP addresses don’t overlap)
Internet Gateway (IGW) – An IGW is a virtual appliance that routes connections from your VPC to the public internet. It’s more an abstract concept than an actual service as you can’t manually configure anything on it, you just send traffic there and pull logs from it.
Nat Gateway – A NAT gateway is a managed NAT. It has a public IP and routes its traffic through the internet, other instances can connect to the NAT to reach out to the internet without needing to expose themselves to incoming connections.
Availability Zone (AZ) – In AWS an availability zone is a separate distinct data center located nearby but in a different area from other AZs. Splitting an application between AZs is a good strategy for redundant and highly available applications.
Public/Private/Data subnet – A public subnet is one that allows traffic from the public internet. A private subnet forces traffic through a NAT. A data subnet does not allow internet traffic at all.
Service Endpoints – Service endpoints allow traffic to pass to AWS services without needing to go over the public internet. They can increase security and reduce bandwidth costs.
NACLs – Network Access Control lists are a set of rules about what traffic is allowed in a subnet.
Security Groups – Security groups are firewall rules that define traffic between and to AWS resources, they are more flexible than NAcls.
VPC-Peering – Peering is the process of allowing two VPCs to talk to one another.
Transit Gateway – Transit gateway is an AWS service that lets multiple VPCs communicate with each other by routing through a central location, which is easier than having to peer every VPC to every other VPC.
There’s been a ton of coverage of the recently discovered Capital One breach. I’m generally very skeptical when AWS security makes the news; so far, most “breaches” have been a result of the customer implementing AWS services in an insecure manner, usually by allowing unrestricted internet access and often overriding defaults to remove safeguards (I’m looking at you, NICE and Accenture and Dow Jones!). Occasionally, a discovered “AWS vulnerability” impacts a large number of applications in AWS – and it also impacts any similarly-configured applications that are *not* in AWS (see, for example, this PR piece…um,…Read More

This post describes how to plumb the Linux VM directly into a hypervisor network, through the use of a bridge.
Start by creating a bridge on the hypervisor system:
> sudo ip link add br0 type bridge
Clear the IP address on the network interface that you'll be bridging (e.g. eth0).
Note: This will disable network traffic on eth0!
> sudo ip addr flush dev eth0Add the interface to the bridge:
> sudo ip link set eth0 master br0
Next up, create a TAP interface:
> sudo ip tuntap add dev tap0 mode tap user $(whoami)The user parameter ensures that the current user will be able to connect to the TAP interface.
Add the TAP interface to the bridge:
> sudo ip link set tap0 master br0
Make sure everything is up:
> sudo ip link set dev br0 up > sudo ip link set dev tap0 up
The TAP interface is now ready for use. Assuming that a DHCP server is available on the bridged network, the VM can now obtain an IP address during boot via:
> qemu-kvm -kernel arch/x86/boot/bzImage \ -initrd initramfs \ -device e1000,netdev=network0,mac=52:55:00:d1:55:01 \ -netdev tap,id=network0,ifname=tap0,script=no,downscript=no \ -append "ip=dhcp rd.shell=1 console=ttyS0" -nographic
The MAC address is explicitly specified, so care should be taken to ensure its uniqueness.
The DHCP server response details are printed alongside network interface configuration. E.g.
[ 3.792570] e1000: eth0 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX [ 3.796085] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready [ 3.812083] Sending DHCP requests ., OK [ 4.824174] IP-Config: Got DHCP answer from 10.155.0.42, my address is 10.155.0.1 [ 4.825119] IP-Config: Complete: [ 4.825476] device=eth0, hwaddr=52:55:00:d1:55:01, ipaddr=10.155.0.1, mask=255.255.0.0, gw=10.155.0.254 [ 4.826546] host=rocksolid-sles, domain=suse.de, nis-domain=suse.de ...
Didn't get an IP address? There are a few things to check:
- Confirm that the kernel is built with boot-time DHCP client (CONFIG_IP_PNP_DHCP=y) and E1000 network driver (CONFIG_E1000=y) support.
- Check the -device and -netdev arguments specify a valid e1000 TAP interface.
- Ensure that ip=dhcp is provided as a kernel boot parameter, and that the DHCP server is up and running.
- Use 'ip' instead of 'brctl' to manipulate the bridge device - thanks Yagamy Light!
- Use 'ip tuntap' instead of 'tunctl' to create the TAP interface - thanks Johannes!
- For performance reasons, I strongly recommend using virtio network adapters instead of e1000.

The National Communications Authority under the Ministry of Communications has launched the Digital Audio Broadcasting (DAB) in Ghana.
In the trial phase, up to eighteen (18) existing FM stations in Accra and Kumasi will share one frequency channel out of VHF band III and transmitter in the two cities.
DAB is a digital radio standard for broadcasting digital audio radio services in many countries around the world. It is expected to provide good quality audio and support the provision of value-added services and spectrum efficiency.
The launch, according to Director General of the NCA, Joe Anokye will “position Ghana as the first country in west Africa and the fourth in Africa to deploy DAB.”
The initiative is to deal with the incessant demand for FM frequency authorizations in the face of severe frequency constraints through technology.
For her part, Communications and Digitalization Minister, Ursula Owusu Ekuful said the government is committed to embracing technologies as part of efforts in enhancing connectivity.
“Ghana’s unwavering commitment to embracing innovation has propelled us to the forefront of digital transformation on the continent and our government through its digital Ghana Agenda launched in 2017, instituted projects and programmes geared towards bringing the digital divide and ensuring digital inclusion for all sectors of the economy,” she said.


This past Tuesday, Jan. 30, Rowan University experienced a campus power issue. The issues caused the Rowan Wi-Fi network to be out of service as well as Rowan’s Public Safety phone lines. Students were sent a text informing them to direct all emergency calls directly to 911, as Rowan Police and emergency services would not be able to be reached during the outage.
The power was restored within an hour, allowing for all networks to be back up and running temporarily. In order for Rowan to fix the network completely, the university called for emergency maintenance on the network infrastructure for Wednesday, January 31 at 10 p.m.
In an email to students, Rowan’s Information Resource and Technology center (IRT) announced the maintenance would cause a Wi-Fi outage as well as out of service phone lines for Rowan’s Public Safety. The Residence Halls on the north side of Route 322 that were affected include Chestnut, Mimosa and Magnolia Halls, as well as the Edgewood Park and Rowan Boulevard Apartments and the Holly Pointe Commons.
However, many students continue to complain about the outages in other living spaces such as the Whitney Center.
