Fenwick mulls cell tower options (though they’re not really towers)
Verizon Wireless wants to improve mobile coverage across coastal Delaware. This month, Verizon engineers designed two proposals to boost signals in Fenwick Island. (They only presented concept plans, but did not submit permit requests, which Fenwick will require for wireless infrastructure.)
Traditionally, when thinking of wireless antennas, people think of tall “macro” towers that reach long distances. But Verizon and other wireless companies are now proposing “small-cell” antennas to boost the signal. That includes canister antennas or panel antennas, usually just a few feet tall, attached to utility poles.
“We have seen an exponential growth in the data usage in wireless coverage for the last few years,” said Verizon’s Bonnie Metz, estimating 50-percent increase in data usage in 2017, due to Verizon’s unlimited data plans and heavy cell phone usage. “We need to add capacity to the network to stay ahead of the demand and to fill gaps in capacity that we’re seeing now. It’s kind of like if you have more traffic, you need more traffic lanes or you’re gonna get a backup.”
Mobile data is used to send multimedia text messages, such as those with photos and video. It also allows cell phones and tablets to access the internet anywhere, without the use of Wi-Fi.
Metz asked for feedback at the Fenwick Island Town Council workshop on Aug. 30.
Design 1 had two 60-foot poles, both in town limits, at town hall and at the Coastal Highway/James Street intersection.
Design 2 had five poles, although only one is in Town limits, with the others in unincorporated Sussex County, including at the Bethany-Fenwick Chamber of Commerce office and on Route 54.
At the council’s request, Metz will research a third design: five poles, but with the Essex Street pole at town hall instead.
Where possible, Verizon will use existing poles or replacements, rather than adding clutter to the street. For comparison, poles would be about the same height or shorter than existing Delmarva Power electric poles, Metz estimated.
Using 4G, preparing for 5G
“Our goal right now is to get 4G coverage as best we can for the whole town,” said Mayor Gene Langan.
“You could do that with two poles,” Metz said. “Putting five poles up now, in my view, is going to position the town better for 5G than just the two poles, because we’re already going to have the infrastructure in place.”
These are the fourth and fifth generations of mobile network technology, each producing a faster wireless network.
In the future, the 5G network will be almost instantaneous but will require more antennas closer to each other and to the ground. Antenna designs are also getting smaller as the technology improves.
No one in the U.S. is using “real” 5G yet. Verizon will introduce it to a few major cities in 2019, then expand over the next few years. Plus, Verizon will invest in early 5G upgrades where infrastructure is ready to go, Metz said.
Residents who supported the five-pole idea encouraged the town council to be forward-thinking, since 5G will arrive in a matter of years. At that time, engineers will propose antenna locations based on future use and technology.
“Anything out there that you’re seeing right now are 4G. … We haven’t put them up anywhere,” Metz said of the 5G equipment. “Everything you’re seeing right now is densification of the 4G network to deal with the capacity issues we’re having.”
The entire coastal area could use a signal boost, so Verizon is also addressing spotty locations around Bethany Beach and Route 26.
Public debates the locations
Council Member Roy Williams said he was hesitant about increasing antennas, partly because he doesn’t want his grandchildren staring at their phones during family vacation.
“I’m like you. When I go on vacation, I don’t want my phone to work,” Metz said. “But statistics show that 83 percent of millennials, when they go to look at a house,” rank cell phone signal as the most important factor when house-hunting, right after school rankings.
“Several Realtors have told me they can’t several really expensive houses in North Bethany because they don’t have coverage,” said Langan.
Resident Barbara Ievoli said mobile access is important for houseguests or family who want to work remotely at the beach.
“5G’s gonna be here before you know it, and I think it’s in our interest and the town’s best interest to look at the long-term plan,” said Ievoli, who previously worked in government. “We put two poles in now, and we’re going to be here next year because 5G is coming. … You have to look at where we’re going in Fenwick. We don’t want to be left behind.”
Other residents agreed, including a former Verizon employee.
Fenwick is having this discussion with Verizon, but not AT&T or Sprint, because the Fenwick Island Police Department uses Verizon for its communications, from cell phones to the patrol car computers. After dropping enough emergency calls and losing connection while downloading arrest records for traffic stops, Town Hall called Verizon for help, just as the company was brainstorming potential improvements to overall beach service.
This spring, Verizon installed a temporary booster antenna at Town Hall, which was mainly to help police who need coverage across the town.
Customers who still suffer poor service can call their provider to report the problems and find solutions.
Discussion on Aug. 30 bogged down as people suggested that a pole “here or there” would guarantee better service for certain parts of town. But Metz emphasized that either plan she presented would cover the entire town, filling all the gaps in service.
Metz will report back to Fenwick Island with updated proposals.

Press conference to be conducted live and on the air - Thursday, June 6, 2013 at 6:00 p.m., Fort Lee Municipal Building, 309 Main Street, Fort Lee, NJ
"Since Hurricane Sandy, Fort Lee government has devoted substantial time and effort on ways to ensure the safety of our residents, especially during times of crisis. The lack of telephone service [both land and cellular], lack of internet service, and state-wide power outages made it virtually impossible for government to properly communicate with the public. The inability to communicate with the public, especially seniors and residents with special needs, which confronted the East Coast will no longer be the case for Fort Lee residents" stated Mayor Sokolich. According to the Mayor, "within days of the aftermath of Hurricane Sandy, we convened regular and mandatory meetings with representatives of our emergency service agencies to identify the challenges we were confronted with and what Fort Lee needed to do to address those challenges. Our mandate was clear and concise. Through an unprecedented inter-municipal initiative, Fort Lee will be among a very small group of municipalities within the entire nation which maintains its own dedicated, functional and reliable emergency radio communication system!"


Package signal implements access to incoming signals.
Notify causes package signal to relay incoming signals to c. If no signals are listed, all incoming signals will be relayed to c. Otherwise, just the listed signals will.
Package signal will not block sending to c: the caller must ensure that c has sufficient buffer space to keep up with the expected signal rate. For a channel used for notification of just one signal value, a buffer of size 1 is sufficient.
It is allowed to call Notify multiple times with the same channel: each call expands the set of signals sent to that channel. The only way to remove signals from the set is to call Stop.
It is allowed to call Notify multiple times with different channels and the same signals: each channel receives copies of incoming signals independently.
Stop causes package signal to stop relaying incoming signals to c. It undoes the effect of all prior calls to Notify using c. When Stop returns, it is guaranteed that c will receive no more signals.


The carriers Liaoning and Type 001A rely on airborne early warning helicopters and an integrated radar system to detect enemies. But these systems with their weaker warning capability risk exposing the carrier's position, the report said. Phased radar carried by an airborne early warning helicopter is limited in size. The early warning distance, time and accuracy is thus limited. An aircraft like the KJ-600 has a larger radar, flies higher than a helicopter and sees farther and more clearly.

The goal of this project is to create a robust faxing engine written in C/C++. The primary operating system is Windows 9x/NT/2K/XP/2003. The engine supports most fax modems using class 1, class 2, or class 2.0 protocols. It uses libtiff to read and write TIFF files. The package contains the source to the fax engine dll and a command-line program that can send and receive faxes. This fax engine was developed by Alt-N Technologies for RelayFax.
The target is a dynamic link library, that contains the code to be able to open a COM port and communicate with a modem to send and receive faxes. A host (fax server) program communicates with the modem through a high-level API provided by the DLL. For each modem that is attached using the API, the DLL creates a thread to handle the I/O and implement the fax protocol.

HTTP stands for “Hypertext Transfer Protocol,” which is a protocol used for transmitting data over the internet. It is the foundation of data communication on the World Wide Web and enables web browsers to communicate with web servers. In this article, we will explore the full form of HTTP and how it facilitates web communication.
Full Form of HTTP
The full form of HTTP is “Hypertext Transfer Protocol.” It is an application protocol that defines how web browsers and servers communicate with each other. HTTP is the foundation of data communication on the World Wide Web and enables the transmission of data, such as text, images, videos, and audio files, between web browsers and servers.
How Does HTTP Facilitate Web Communication?
HTTP facilitates web communication by defining the rules and formats for data transmission over the internet. Here are some of the key features of HTTP:
- Client-Server Model: HTTP follows a client-server model, where web browsers act as clients and web servers act as servers. The client sends a request to the server, and the server responds with the requested data.
- Stateless Protocol: HTTP is a stateless protocol, which means that each request and response is treated as an independent transaction. The server does not keep track of previous requests or sessions.
- Request Methods: HTTP defines different request methods, such as GET, POST, PUT, DELETE, and HEAD, which are used for different types of requests. For example, GET is used for retrieving data, while POST is used for submitting data.
- Status Codes: HTTP defines different status codes, such as 200, 404, and 500, which indicate the status of a request. For example, a status code of 200 indicates that the request was successful, while a status code of 404 indicates that the requested resource was not found.
- Header Fields: HTTP defines different header fields, such as Content-Type, Content-Length, and Cache-Control, which provide additional information about a request or response.
In conclusion, HTTP is a protocol that enables web communication and defines how web browsers and servers communicate with each other. It follows a client-server model, is a stateless protocol, defines different request methods and status codes, and includes header fields for additional information. Understanding HTTP is essential for anyone involved in web development or web communication.


The US Air Force drone RQ-4B Global Hawk for 10 hours made a monitoring flight along the demarcation line in Donbas.
The aircraft monitored along the front line from the territories controlled by the Ukrainian authorities, while it was at an altitude of about 15.5 thousand meters, the Ukrainian military portal reports.
It is clarified that the drone's tasks are capable of monitoring hundreds of kilometers into the enemy’s territory — a high-resolution camera, an infrared sensor and a radar for tracking moving objects are installed on board, designed to conduct strategic information gathering to a depth of more than 300 km. When flying at high altitudes, Global Hawk is able to survey large areas, carry out high-resolution point targets, and transmit data in real-time through a satellite communication channel.
The American drone that conducted the monitoring flew from an air base in Italy. The route of his flight to Donbas ran through Greece, Bulgaria, and Romania. It crossed the border of Ukraine to the north of Moldova.


An RFID (Radio Frequency Identification) tunnel reader is a device that uses radio waves to read and capture information from RFID tags as they pass through a designated area or tunnel. The tunnel reader consists of an antenna that emits radio waves, and a reader or receiver that captures the data transmitted by the tags.
The tunnel reader is often used in logistics and supply chain management to track and monitor the movement of goods, especially in large warehouses or distribution centers. As the tagged items pass through the reader’s field, the reader captures their unique identifier and transmits it to a database for tracking and analysis.
The RFID tunnel reader can also be used in other applications, such as inventory management, asset tracking, and access control. It offers a fast and efficient way to collect data on large numbers of items in a short amount of time, without the need for manual scanning or data entry.
Overall, the RFID tunnel reader is a useful tool for businesses and organizations looking to improve their tracking and monitoring capabilities, increase efficiency, and reduce errors in their operations.


Mobile phone detection cameras have now gone live in NSW to target illegal mobile phone use while driving.
As a result, some local truckies have been asking, "If it's illegal to hold a mobile phone while driving, is it also illegal to hold a CB microphone while driving?". This is also relevant to radio hobbyists and tradies who use CB radio.
The answer can be found in Rule 300 of the NSW Road Rules, which states that:
"The driver of a vehicle must not use a mobile phone while the vehicle is moving, or is stationary but not parked…"
However, the definition of "mobile phone" does not include a CB radio or any other two-way radio.
This means that using a hand-held CB microphone is not illegal under the legislation that bans the use of mobile phones while driving. So long as the driver still has proper control of the vehicle, there is no wrongdoing.
Having said that, mobile phone detection cameras use artificial intelligence to detect mobile phone use and we all know that artificial intelligence isn't always so intelligent!
It is certainly possible that the cameras could analyse an image of a driver using a CB radio and place that driver in the list of potential offending drivers. The image would then go to a human to review.
We would assume that a CB microphone would be obvious to any reviewer (especially where there is a visible microphone cable), but just like artificial intelligence humans don't always get it right!
If you or someone you know is issued with a penalty notice for a traffic offence that you feel that you have not committed, do not hesitate to contact our friendly team at Kenny Spring on 1800 650 656. We're here to help!

What is a SAN Switch?
A SAN switch is a high-performance networking device that connects servers and storage devices in a dedicated Storage Area Network (SAN). It provides a reliable, scalable, and secure way to transfer data between devices in a SAN. SAN switches come in various sizes and types, each with different port densities, speeds, and features. A typical SAN switch consists of several components, including ports, power supplies, management modules, and firmware.
Types of SAN Switches
There are several types of SAN switches available on the market, including:
Fibre Channel (FC) Switches:
They support high-speed, low-latency data transfers and offer advanced storage features, such as data replication and snapshotting.
iSCSI switches are used in iSCSI-based SANs, which use standard Ethernet networks to transfer data between devices. iSCSI switches are typically less expensive than Fibre Channel switches but may not offer the same level of performance.
FCoE switches are used in Fibre Channel over Ethernet (FCoE) SANs, which allow Fibre Channel traffic to be transmitted over Ethernet networks. FCoE switches are designed to handle the unique requirements of FCoE traffic, such as lossless transmission and low latency.
InfiniBand switches are high-speed networking devices that can be used in SANs to provide extremely low latency and high bandwidth. InfiniBand switches are typically used in high-performance computing (HPC) environments, such as research institutions and scientific labs.
The choice of SAN switch depends on the specific requirements of the SAN and the applications that will be running on it. Organizations should carefully evaluate their needs and consider factors such as performance, scalability, and cost when selecting a SAN switch.
Why Are SAN Switches Important?
SAN switches are essential for several reasons:
Efficient Data Transfer:
SAN switches provide dedicated and isolated connections for data transfer between servers and storage devices. This ensures that data can be transferred quickly and efficiently, without interference from other network traffic. SAN switches also support high-speed data transfers, which are necessary for applications that require low latency and high throughput.
SAN switches offer high availability through redundant components, such as power supplies and management modules. This ensures that the SAN can continue to operate even in the event of a component failure. SAN switches also support features such as failover and load balancing, which further enhance availability and ensure that data is always accessible.
SAN switches are designed to be highly scalable, allowing organizations to easily add or remove storage devices or servers as needed. This flexibility enables organizations to adapt to changing business needs and accommodate future growth.
SAN switches offer advanced security features, such as access control and encryption, to ensure that data is protected from unauthorized access or theft. These features are essential for organizations that handle sensitive data, such as financial institutions or healthcare providers.
Advanced Storage Features:
SAN switches provide advanced storage features, such as data replication and snapshotting, which enable organizations to protect data and recover quickly in the event of a disaster. These features can also improve data management and simplify backup and recovery processes.
In summary, SAN switches are critical components of a modern data center infrastructure. They provide efficient data transfer, high availability, scalability, security, and advanced storage features that are necessary for modern businesses to operate effectively and compete in today’s digital landscape.
How Do SAN Switches Work?
SAN switches operate by creating a dedicated and isolated network for storage traffic between servers and storage devices. This network is typically implemented using Fibre Channel or Ethernet protocols, depending on the type of SAN switch being used.
When a server needs to access data from a storage device, it sends a request to the SAN switch. The switch then uses a routing table to determine the best path for the request to reach the intended storage device. This ensures that data is transferred as efficiently as possible and that traffic is evenly distributed across the SAN.
The SAN switch also provides advanced features such as zoning and virtualization. Zoning allows administrators to group servers and storage devices together to limit access to specific areas of the SAN. This improves security and prevents unauthorized access to data.
Virtualization allows multiple physical storage devices to be presented as a single logical device, simplifying management and improving efficiency. This feature also enables organizations to easily move data between different storage devices without disrupting the operation of the SAN.
SAN switches also provide advanced monitoring and management capabilities, allowing administrators to monitor traffic, troubleshoot issues, and optimize performance. This includes features such as Quality of Service (QoS), which enables administrators to prioritize traffic based on importance, ensuring that critical data is always given priority.
Overall, SAN switches provide a reliable, scalable, and secure way to transfer data between servers and storage devices. They use advanced networking protocols and features to ensure that data is transferred efficiently, securely, and reliably, making them an essential component of modern data center infrastructure.
In conclusion, SAN switches are a critical component of modern data center infrastructure. They provide dedicated and isolated networks for storage traffic, enabling efficient, secure, and reliable data transfer between servers and storage devices. SAN switche offer advanced features such as zoning, virtualization, and monitoring and management capabilities, which improve security, scalability, and performance. With the ability to easily add or remove storage devices or servers as needed, SAN switches offer the flexibility and agility required to meet the changing needs of modern businesses. As data continues to grow in importance and complexity, SAN switche will remain an essential component of any organization’s data center strategy.

Recently, Google officially launched Android 9 Pie, which includes a slew of new features around digital well-being, security, and privacy. If you’ve poked around the network settings on your phone while on the beta or after updating, you may have noticed a new Private DNS Mode now supported by Android.
This new feature simplifies the process of configuring a custom secure DNS resolver on Android, meaning parties between your device and the websites you visit won’t be able to snoop on your DNS queries because they’ll be encrypted. The protocol behind this, TLS, is also responsible for the green lock icon you see in your address bar when visiting websites over HTTPS. The same technology is useful for encrypting DNS queries, ensuring they cannot be tampered with and are unintelligible to ISPs, mobile carriers, and any others in the network path between you and your DNS resolver. These new security protocols are called DNS over HTTPS, and DNS over TLS.
Android Pie only supports DNS over TLS. To enable this on your device:
- Go to Settings → Network & internet → Advanced → Private DNS.
- Select the Private DNS provider hostname option.
1dot1dot1dot1.cloudflare-dns.com and hit Save.
- Visit 18.104.22.168/help (or 22.214.171.124/help) to verify that “Using DNS over TLS (DoT)” shows as “Yes”.
And you’re done!


New Fluke Cat 7 Test Solution for GG45
GG45 channel adapter now available for DTX-1800
Based on our new PCB 8-pin GG45 jack, Fluke Networks has developed a Cat.7 channel adapter for the DTX-1800 tester enabling field certification of GG45 installations.
The Fluke Channel Adapter can be used in combination with a Nexans Cat 7 measurement cord (N900.679). The appropriate test limit is ISO 11801 Class F Channel.
Laboratory tests in Nexans Competence Centre, Buizingen, have demonstrated excellent consistency with Network Analyser results and have confirmed the accuracy to be better than 2dB. This exceeds the Level IV accuracy standard and provides a reliable fi eld testing solution for LANmark-7 cabling systems.
Channel Adapters allow measurement of a Cat 7 node at much lower cost than permanent link testing. Due the fact that test plugs wear out and have to be replaced after ~750-1000 measurements, test adapters have to be exchanged frequently. Using channel testing only the patch cords, which are available at a fraction of cost compared to Permanent Link adapters, have to be replaced.
With this new adapter, all 3 major field test manufacturers (Agilent, Ideal and Fluke) now support GG45. Installers can now use the same test device for Cat.6 and Cat.7, just by exchanging the test adapter, thereby removing the need for “special” test equipment for Cat.7.
The Channel adapters are available now from Fluke Networks.
- DTX-CHA012S : GG45 Channel Adapter Set
- DTX-REFMOD : Reference Module
The Measurement cords are available in stock from Nexans.
- Part Number : N900.679


Flexroute Digital Receiver
From Rivendell Wiki
The Flexroute Digital Receiver ouputs serial data that can be used to fire off events in Rivendell. You need to have Rivendell monitor the serial strings being sent out for the desired command and act upon it.
The Rivendell Macro Language has the following command for the ripcddaemon to act upon incoming serial data.
|INSERT SERIAL TRAP
Syntax: SI <port> <cart> <string>!
Insert a serial trap to execute the macro cart <cart> upon receipt of <string> on serial port <port>.
Q: This looks like it's meant to do the job, however the problem we have found is the serial data string contains more than just the switch code we are looking for, EB is the trigger string in the data stream in our case. If the string EB has to be a exact match to the serial data string then it won't work. If the string can be set to trigger upon seeing EB in the serial data stream then it will work. This is how it's done now and we are hoping that the string can be set to *EB* = anything switchcode anything.
A: Just using 'EB' should do what you want. No stars necessary (we're not using regexes here).

In March 1985, a new air traffic control tower opened at the former Greater Pittsburgh International Airport terminal, becoming the tallest control tower in the country at the time. Today, the same 227-foot tower controls air traffic for Pittsburgh International Airport.
A photo from November 1982 shows construction of what would be the tallest FAA tower at the time. (Photo by Allegheny County Department of Aviation)
But where was air traffic controlled before then?
The Greater Pittsburgh International Airport terminal opened in 1952, and its original air traffic control tower was located on top of the highest point of the old terminal, above the airport’s rotunda area.
The photo below, taken inside the original Greater PIT control tower, overlooks the airfield.
Light guns are visible above the air traffic controllers in the photo. Technology that still exists in air traffic towers today, light guns can be used to guide pilots as they maneuver their aircraft on the ground in cases of radio transmission failures, among other situations.
A photo of the original air traffic control tower at Great Pittsburgh Airport, taken sometime between 1952 and the early 1960s. (Photo taken by the Allegheny County Department of Aviation)
The original tower oversaw air traffic for Greater PIT until the new tower opened across the airfield in 1985. Planning and construction for the new, 20-story tower that stands as Pittsburgh International’s FAA tower today took about four years.

In order to wirelessly connect to your home’s smart tools, you must have a reliable mode of communication. This is where Z-wave technology enters the equation. Explore more about this wireless connectivity standard and why it’s well known for home automation.
What Is Z-wave Technology?
Switching on your lighting from afar or letting your thermostat adjust automatically based on the hour seems quite advanced, right? Home automation seems like a modern advancement to many of us, but the technology that powers it has actually been around for quite some time. In fact, Z-wave has been in use for in excess of 20 years. Basically, it is a method of wireless communication that enables you to operate and automate components within your home, like door locks, lighting, and thermostats. Looking at it from a different perspective, it’s what makes smart homes smart.
It’s worth noting that Z-wave works in a mesh network, which means that gadgets not only interact to the central interface but also with each other. Would you like to have your foyer light activate when the front door is unlatched? This kind of integration can be done with Z-wave.
Why Z-wave Devices In Bloomington Make Sense For Your Home
Z-wave devices are fundamental to your home’s automation thanks to their wireless capability. While Z-wave technology is similar to other means of wireless connectivity, like Wi-Fi and Bluetooth, it does operate a little differently. One of the crucial divergences is that it functions on a significantly lower radio frequency than Wi-Fi. What this signifies is that you don’t need to worry about Z-wave devices experiencing interference with all the smartphones, televisions, and other mobile devices linked to your principal wireless network.
Here are some advantages of Z-wave technology:
- Allows for remote access and automated function of your home’s smart features
- Reliable, low-power radio waves will easily travel through walls and floors
- Encrypted communications between your devices and hub
- Less network interference and congestion than Wi-Fi as Z-Wave operates on a lower frequency
- Mesh network and two-way communications give components the opportunity to connect with one another and the main interface
- Works with smart speakers from Amazon or Google, letting you manage components with vocal instructions
Since Z-wave technology has been around for quite a long time, it has undergone a number of adaptations and improvements to enhance its capabilities, reliability, and security. You don’t have to feel anxious about whether the front door truly fastened when you scheduled them to.

When Ethiopia announced on May 9 that it was launching trials for its first 5G mobile network in its capital, it joined more than a dozen African countries that are either testing or have rolled out the next-gen network. But just as for its 5G peers, the journey isn’t going to be smooth.
Governments in Africa are optimistic that they will one day use 5G to do large-scale farming using drones, introduce autonomous cars into roads, plug into the metaverse, activate smart homes and improve cyber security. Some analysts predict that 5G will add an additional $2.2 trillion to Africa’s economy by 2034.
But Africa’s 5G first movers are facing teething problems that stand to delay their 5G goals. The challenges have revolved around spectrum regulation clarity, commercial viability, deployment deadlines, and low citizen purchasing power of 5G enabled smartphones, and expensive internet.
Where things stand for Africa’s 5G pioneers
Ethiopia is joining Botswana, Egypt, Gabon, Kenya, Lesotho, Madagascar, Mauritius, Nigeria, Senegal, Seychelles, South Africa, Uganda, and Zimbabwe, when it comes to testing or deploying 5G. But many of these countries are facing delays.
Botswana: On Feb. 25, Botswana’s Mascom unveiled 5G to residents of the capital Gaborone. It started with four sites in the city, with a plan to lay more than 100 base stations by the end of 2022.
Egypt: Last February, Orange received spectrum from the Egyptian government that now allows it to test 5G networks just like Vodafone Egypt, Egypt Telecom and Etisalat Egypt. Though promising, Egyptians will have to wait for 5G services.
Gabon: Since it started testing the technology in November 2019, Gabon’s Gabon Telecom is yet to go commercial. Its CEO is targeting 2023.
Kenya: Ethiopia’s southern neighbor, has been testing the technology for a year now, but internet subscribers will have to wait till the end of the year, when the country’s telecoms regulator is expected to have issued mobile operators with 5G licenses. The country is expected to account for more than half of the continent’s tiny number of 5G mobile subscriptions in 2026.
Lesotho: Since Vodacom was given a temporary spectrum by the Lesotho government in 2018 to experiment with 5G technology, it has been a journey of pain. Wrangles between Vodacom, Econet and the regulator have hindered any meaningful 5G roll-out.
Madagascar: In July 2020, Madagascar’s Telma followed South Africa to launch a commercial 5G but three weeks later, the country’s regulator told the company to halt its plans.
Mauritius: On July 30 last year, the government of Mauritius announced the country’s first 5G network deployment to cover four zones but didn’t share plans for a fully commercial roll-out.
Nigeria: The continent’s largest economy, issued spectrum licenses in March, and is hoping to possess the widest 5G network in the continent this year. It is looking at August for commercial deployment.
Senegal: Since their first 5G tests in November 2020, Senegal’s Sonatel and Orange continue to do a number of trials in Dakar but the network still remains largely unoperational.
Seychelles: Citizens greeted the country’s 5G launch in 2020 with mistrust, expressing concern over health hazards. A year later, citizens in six regions are getting faster speeds of 1.2Gbps from Cable and Wireless Seychelles, for up to 100GB of use.
South Africa: The continent’s earliest adopter of 5G rolled out the technology on a temporary spectrum, but amid heavy strain on networks during the pandemic, Vodacom, Rain, and MTN were ordered to suspend that use from November 2021. In March, the country earned nearly $1 billion from its long-awaited 5G spectrum auction.
Uganda: In January 2020, Uganda became the first east African nation to test the possibility of launching a 5G network with ZTE and MTN. But a commercial launch is yet to happen.
Zimbabwe: On Feb. 24, Zimbabwe’s Econet announced that it had launched the country’s first 5G network and would activate two dozen sites by this month.
Expensive 5G smartphones slow adoption
Safaricom, the operator leading 5G adoption in Kenya, this month said that the high cost of 5G-enabled smartphones is slowing down the company’s ambition to offer mobile 5G services. The cheapest smartphone with a 5G smartphone in the continent goes for about $300, which is very expensive for the average African. One study in Kenya revealed that 94% of the population owns devices costing less than $200.
“That’s one of the reasons why we are focusing more on the 4G side and leaving 5G to serve the homes,” Safaricom CEO Peter Ndegwa told the Business Daily newspaper.
Africa needs to work hard on 4G first
The desire to catch up with the rest of the world has seen improvements in the existing 4G networks on which most countries plan to switch on 5G. As of 2019, 4G internet signals covered about half the continent, according to the industry body GSMA. Yet only 10% of Africa’s population presently uses 4G, a recent report from telecom firm Vodacom said.
Even more detrimental to the 5G dream is the fact that 4G network services in Africa are only available in urban and peri-urban areas as many providers try to deploy internet in areas with high usage to remain profitable, leaving villages years away from experiencing higher speed internet.
For now, 3G is still adding users. And the reality is that 42 African states are yet to start thinking about 5G.
