Chinese telecommunications firm Huawei Technologies has voiced its support of advanced sharing of C-band (3400-3800MHz) spectrum in key regions on the continent.

The technology ICT solutions provider participated in the 2015 Sub-Sahara Spectrum Management Conference, held  in Johannesburg.

The Conference attracted high-level stakeholders and decision makers from Sub-Saharan Africa and beyond, to discuss topical issues relating to the management and co-ordination of spectrum policy within the region.

In a media statement Huawei confirmed its support of efforts to secure the availability of adequate spectrum for wireless broadband services relying on 4G technology, as well as for future 5G technologies.

“Voice and mobile Internet connectivity have improved rapidly in most urban areas in Africa. Sub-Saharan Africa (SSA) has been the fastest growing region over the past five years in terms of both unique subscribers and connections. Consumers, governments, and businesses across SSA are rapidly adopting mobile, not only as a basic communication tool, but also to access information and a growing range of new applications and services

However, the “digital divide” is still at its most extreme in Africa. In absolute terms, mobile broadband connectivity is still at a very early stage of development in comparison to other regions of the world. ,” the statement read.

The argument put forward at the Conference was that without the smart management of spectrum, mobile networks will struggle to meet growing data demands resulting in slower speeds and higher prices, thus hindering Africa from experiencing the full socio-economic benefits of mobile.

There are 8 months remaining until the 2015 World Radio Conference where key decisions will be made impacting the future of mobile broadband over the next year.

The global debate has now focused on potential bands for mobile allocations and IMT identifications: UHF band (470-694 MHz), L-Band 1350-1518 MHz, 2700-2900 MHz band, and C-Band (3400-3800 MHz and 3800-4200 MHz).

With the tremendous increase in end user mobile data traffic, Huawei has predicted that the 3400-3800 MHz range will play an increasing role in the evolution of LTE-Advanced, thanks to the unique amount of contiguous spectrum available (<6GHz) that will allow delivery of a unique end user mobile broadband experience (i.e. up to 1Gbps peak).

Making these four bands available for mobile services, including the 3400-3800 MHz band, does not mandate a change of use for the spectrum at a national level, but instead it gives countries the freedom to take the decision to make additional spectrum available for mobile broadband when demand from the market and society heightens.

In the meantime, countries may want to use, in some cases, more advanced approaches to spectrum sharing between different services as a means of managing spectrum congestion and enabling innovation, while preserving current usage.

During his address to conference delegates, Alessandro Casagni, head of the European Wireless Regulatory Policy at Huawei, elaborated on how more advanced approaches to spectrum sharing may enable mobile broadband innovation while preserving current usage.

Such approaches for spectrum sharing, should be assessed at national level, accounting for the latest technologies (including the availability of LTE-Advanced small cells), while ensuring the continued operation of existing services. The regulations at a national level should be aimed at allowing the introduction of IMT networks with the least prescriptive sharing regulation necessary to protect existing users while maximizing efficient use of spectrum.

The latest mobile network topologies such as small cells, within LTE-Advanced Heterogeneous Networks (HETNETs), and the exploitation of innovative spectrum management approaches such as “database assisted spectrum access”, are now providing additional opportunities for sharing leading to more efficient utilisation of spectrum.

US Newspapers Sue OpenAI, Microsoft Over AI Chatbots

Published

Kindly share this post

Eight US newspapers sued OpenAI and Microsoft in a New York federal court Tuesday for violating their copyright to train the technology behind the ChatGPT and Copilot chatbots.

The newspapers, which include The New York Daily News and The Chicago Tribune, are owned by Alden Global Capital, a Florida-based hedge fund that created the second-largest US newspaper group behind USA Today owner Gannett when it bought the Tribune publishing chain in 2021.

“This lawsuit arises from defendants purloining millions of the publishers’ copyrighted articles without permission and without payment to fuel the commercialization of their generative artificial intelligence products, including ChatGPT and (Microsoft’s) Copilot,” according to the filing.

“As this lawsuit will demonstrate, defendants must both obtain the publishers’ consent to use their content and pay fair value for such use,” the filing said.

OpenAI and its Microsoft backer were also accused of offering up verbatim excerpts of full articles as well as attributing misleading or inaccurate reporting to the publications in certain requests.

Other newspapers involved in the suit were The Orlando Sentinel, The Sun Sentinel of Florida, The San Jose Mercury News, The Denver Post, The Orange County Register and The St. Paul Pioneer Press.

In a statement, OpenAI did not refer to the accusations specifically but said “we take great care in our products and design process to support news organizations.”

OpenAI pointed to the “constructive partnerships and conversations with many news organizations around the world to explore opportunities, discuss any concerns, and provide solutions.”

This referred to the news outlets that have entered partnerships with the Microsoft-backed startup instead of going to court.

They include The Associated Press, Financial Times, Germany’s Axel Springer, French daily Le Monde and Spanish conglomerate Prisa Media.

The suit on Tuesday closely resembles a case filed by The New York Times in December, in which OpenAI is also accused of stealing content to train its powerful AI.

In that case, OpenAI strongly pushed back, arguing the use of publicly available data including news articles for general training purposes is fair use.

OpenAI also accused the Times of violating ChatGPT’s user guidelines to generate the content that suited its case.

Microsoft declined to comment on the suit.

Nigeria’s mobile network landscape is seeing a gradual shift towards newer technologies, with 5G subscriptions reaching 2.7 million in March 2024, according to the Nigerian Communications Commission (NCC).

5G Subscriptions Hit 2.7m in Nigeria –NCC

This translates to a 1.24 per cent penetration rate.

While this represents steady growth compared to December 2023 (1.04%), 2G remains the dominant network choice, accounting for over half (56.97%) of all connections. 3G holds a 9.04% share, while 4G subscriptions have grown significantly from 25.06% in May 2023 to 32.74% in March 2024.

The high cost of 5G-compatible smartphones is a major barrier to wider adoption. Although all three major operators – MTN, Airtel, and Mafab Communications – offer 5G services in select cities, expanding coverage and affordability remain key challenges.

MTN launched the first 5G network in September 2022, followed by Airtel in June 2023. Mafab entered the market later in 2023. All three companies are aiming to expand their reach, but the high cost of 5G devices is a significant deterrent for many Nigerians.

According to Mohammed Rufai, chief technical officer, MTN, maintaining older networks (2G and 3G) alongside newer ones is necessary due to device compatibility issues.

This highlights the need for a wider range of affordable 5G-compatible phones to truly unlock the potential of this next-generation technology in Nigeria.

Experts Seek Stricter Regulation against Call Masking, SIM-Boxing Fraud

Published

Experts have called for stronger laws and stricter regulation to tackle security issues around call masking and Subscriber Identity Module (SIM)-boxing-related fraud in Nigeria, according to the Nation.

Experts Seek Stricter Regulation against Call Masking, SIM-Boxing Fraud

Call masking or refilling is a practice in which international calls are terminated in Nigeria as local numbers, using illegal SIM boxes loaded with several numbers.

It is a deliberate attempt by fraudsters to avoid paying the correct International Termination Rate (ITR) for international calls, paying instead the Local Termination Rate (LTR).

For example, when the number is masked as a local call, an operator pays N3.90 LTR and not N24.40 ITR.

The process allows operators to terminate inbound international telecoms traffic as local calls, so they do not have to pay ITR, which is the interconnection charge set by telecoms traffic carriers as carrier-to-carrier charges.

A SIM Box fraud is a setup where fraudsters install SIM boxes with multiple prepaid SIM cards.

A fraudster can bring calls through VOIP (through the internet) and terminate international calls through local phone numbers from a country, to make it appear as a local call, by initiating the call through a local SIM installed in the SIM box.

About three years ago, when the issue came to the limelight, the Nigerian Communications Commission (NCC) carried out some investigations, leading to the sanctioning and suspension of some operators earlier this year.

Some of these suspensions were later lifted.

The Office of the National Security Adviser (ONSA), the National Intelligence Agency (NIA), the Department of State Services (DSS), and Committees of the House of Representatives and Senate have on several occasions expressed concern about the menace.

While many stakeholders believe that the menace has been nipped in the bud, it has continued to rear its ugly head to the bewilderment of experts and stakeholders.

Ikechukwu Nnamani, president/chief executive officer of Medallion Communications Limited, lamented that it is a subject matter, which NCC should address completely.

Nnamani, who is an executive member of the premier telecom body in Nigeria – the Association of Telecommunications Companies of Nigeria (ATCON), said almost all calls he received recently are masked.

“Sometimes, I don’t pick up calls because I do not know the number only to find out later it was an international call.

“The truth is that I don’t know why this has not been resolved, I expected it to have been solved.

“Honestly, I would not know why. One would have expected them to have sorted all these out by now,” he said.

Chief Deolu Ogunbanjo, president of the National Association of Telecommunications Subscribers of Nigeria (NATCOMS) said there was no need to relent in reporting the menace to the right authority.

He said it could be a plan to ensure that gain accrued to some people. “I don’t know whether call masking favours the operator or it is being done deliberately.

“It is a situation that the telecoms should deal with because it is a technical problem. I think it is some of those unlicensed operators doing all these.

“Some of these operators’ facilities are being tapped into; they need to look into their operations, so they can be taken care of.

“If they are still in the habit of doing it, proper sanctions should be meted out to any erring service provider.

“There should be heavier sanctions. They can’t be short-changing subscribers and at the same time, the government,” he said.

Mr. Ajibola Olude, executive secretary of the Association of Telecommunications Companies of Nigeria (ATCON), believes the issue can be addressed.

“When it comes to technology, you can only address it maximally. It is not as rampant as before and it is an international issue.

“We have addressed it before and we will look at it again.

“About four years ago, when it happened, we deployed all the resources within our capacity to address it and I think it was addressed maximally.

“I have not seen any operator complaining, except now that you are raising the issue, but as far as we know, call-masking is no longer a problem.

“I am going to contact our compliance monitoring to enlighten me about what is going on, but it is no longer an issue,” he said.

Mouka Reuben, director, Public affairs, NCC, said the situation has been tackled before and he does not think it was a major issue again.

He, however, promised that the commission would look into it again to find a way out.

NCC recently put the revenue lost to call-masking and SIM-boxing activities in the country at $3 billion.

This is as telecom operators lamented during the 85th edition of the Telecom Consumer Parliament in Lagos that they were losing about N2.5 million minutes per day to these fraudulent activities.

On actions that had been taken by the commission to combat the menace, Prof Umar Danbatta,  former Executive Vice-Chairman, NCC, said the NCC had tightened the SIM registration process across all networks to reduce the availability of SIM cards for SIM-boxing as well as address the security issues around the availability of pre-registered SIMs.

According to him, the action was necessary as some arrests made in Lagos two weeks ago showed that the perpetrators of SIM-boxing had over 100 SIM cards registered with fictitious names and used them to divert international calls.
