IBM and Ericsson on Monday announced a research breakthrough that could accelerate the launch of 5G communications networks and support new mobile enterprise and user experiences enabled by very high data rates, including IoT, connected vehicles, and immersive virtual reality.

The companies have created a compact silicon-based millimeterWave (mmWave) phased array integrated circuit operating at 28GHz that has been demonstrated in a phased array antenna module designed for use in future 5G base stations.

2017 has been described as a defining year for 5G. More countries and governments are opening up new frequency portions of the electromagnetic spectrum, including portions known as millimeter wave bands, which are more than 10 times higher than the frequencies currently used for current mobile devices, offering a new source of bandwidth for cellular networks that are being made available for 5G networks.

Scientists at IBM Research and Ericsson reached their breakthrough as a result of a two-year collaboration that set out to develop phased array antenna designs for 5G. IBM’s expertise in highly integrated phased array mmWave IC and antenna-in-package solutions, together with Ericsson’s expertise in circuit and system design for mobile communications, helped the team reach several new technological milestones.

Thomas Noren, Senior Advisor, Business Unit Network Products, Ericsson, says: “There has been a lot of encouraging progress in 5G standardization last year including the beginning of live field trials. Big efforts in research and development are key to this and our collaboration with IBM Research on phased array antennas can help operators to effectively deploy radio access infrastructure necessary to support a 5G future. New use cases and applications that span human machine interaction, Virtual Reality, smart home devices and connected cars will depend on innovative technologies that can bring the promises of faster data rates, broader bandwidth and longer battery life to reality.”

“The development of this 5G millimeterWave phased array is an important breakthrough, not just because of its compact size and low cost, which make it a very commercially attractive solution for network equipment companies and operators, but its potential to unleash and inspire brand new ideas and innovations we haven’t yet imagined, thanks to a fully networked society,” said Dr. Dario Gil, Vice President of Science & Solutions, IBM Research.

Making 5G A Reality
The first release of the 3GPP 5G specification is targeted to be ready by 2017/2018, but there has already been much progress in the industry with field tests and demonstrations of new user experiences and capabilities made possible by the higher bandwidth, lower latency, greater density and lower energy requirements of 5G networks.

5G is expected to support data rates exceeding 10Gbps in certain scenarios. New capabilities are designed to allow users to download a full-length HD movie in seconds, provide very high bandwidth and uninterrupted live streaming experiences in highly dense environments such as sports or concert venues, experience ‘life-like’ response times to enable remote surgery or fully immersive virtual reality experiences, as well as see battery life of 10 years for remote cellular devices that may be part of IoT environments.

The Phased Array Antenna Module Breakthrough
For future 5G phased array deployments to be commercially viable the size, weight, cost and performance of the component are important factors.

The IBM and Ericsson team’s result, the world’s first reported silicon-based mmWave phased array antenna module operating at 28GHz, is a significant step towards meeting this challenge. The module, which consists of four monolithic integrated circuits and 64 dual-polarized antennas, measures approximately 2.8” by 2.8”, or about half the size of a typical smartphone. Achieving this compact form factor is necessary to support the vision of this technology’s widespread deployment, especially in indoor spaces and dense downtown areas.

Another performance advance reported by the team is the demonstration of concurrent dual-polarization operation in transmit and receive modes.

This capability enables one phased array antenna module to form two beams simultaneously, doubling the number of users to be served at the same time and so improving the overall value and economics of the technology.

A major hurdle for the use of mmWave signals in mobile communications is achieving sufficient range between radios to support target applications. At 28 GHz, each antenna is tiny and individually would support short communication distances, but combining multiple such tiny antennas not only increases the range but also enables steering of signals in specific directions. The IBM and Ericsson team’s phased array design supports beam-steering resolution of less than 1.4 degrees for high precision pointing of the beam towards users.

IBM Communications Circuits & Systems Innovation
IBM Research has a long history designing and developing integrated circuits and phased arrays, and were pioneers of the first monolithic mmWave radio in 2006. In 2013, the team presented results of a highly integrated mmWave phased array transceiver for both mobile communications and radar imaging applications that laid the foundation for this latest scientific work.

The IBM scientists have also explored how mobile handsets will communicate at new mmWave frequencies, showing a path for how mmWave 5G radios could be implemented in mobile phones.

A paper describing the IBM Research and Ericsson team’s work, “A 28GHz 32-Element Phased-Array Transceiver IC with Concurrent Dual Polarized Beams and 1.4 Degree Beam-Steering Resolution for 5G Communications,” will be presented on February 7 at the 2017 International Solid State Circuits Conference in San Francisco.

X Suspends Twitter Account for Rules Violation

Published

X, the social media platform formerly known as Twitter, has suspended the @Twitter account, replacing its profile with a standard notice citing violation of platform rules.

X Suspends Twitter Account for Rules Violation

Musk

The action, which occurred on Sunday, January 11, left users encountering the handle greeted by a bold “Account Suspended” message on a black screen, with no details provided on the specific rules broken or the duration of the suspension.

The development has sparked widespread confusion and nostalgia among users, given that Elon Musk rebranded Twitter to X in July 2023, approximately six months after acquiring the platform for $44 billion in late 2022.

The @Twitter handle had remained dormant since before Musk’s takeover, serving as a legacy remnant of the platform’s original branding, and its suspension appears to mark the final erasure of the Twitter name amid X’s ongoing efforts to combat spam, impersonation, and rule violations.

X’s official statement on the suspended page simply reads: “X suspends accounts that violate our rules,” without offering an appeal process or further explanation, unlike standard user suspensions.

Public reactions on social media ranged from humorous laments of “RIP Twitter” to speculation that the move resulted from automated moderation or a deliberate cleanup of legacy trademarks.

xAI’s Grok AI described it as a purposeful retirement of outdated elements rather than a genuine infraction, while neither Elon Musk nor X spokespeople issued any comment as of Monday morning.

This incident underscores the evolving identity of the platform under Musk’s ownership, which also saw a domain shift to x.com in 2024, further distancing it from its Twitter roots.

Industry observers note that while the suspension aligns with X’s stricter enforcement policies, the lack of transparency has fueled debates on consistency in applying rules to high-profile legacy accounts.

Federal Government plans to channel $460m World bank loan, representing about 92 per cent of a $500m, into the proposed fibre infrastructure company set up to deploy 90,000 kilometres of climate-resilient broadband fibre across the country.

This is contained in the Financing Agreement for the Building Resilient Digital Infrastructure for Growth project between the Federal Government and the International Development Association, the concessional lending arm of the World Bank.

Under the agreement, the World Bank approved a $500m concessional credit to support Nigeria’s drive to expand access to high-quality and climate-resilient broadband internet in unserved and underserved areas.

Of this amount, $460m is earmarked specifically for equity financing and capitalisation of a new Project Company that will drive the fibre rollout. The remaining $40m will cover goods, works, consulting and non-consulting services, training, operating costs, and the refund of a preparation advance used to develop the project framework.

According to the document, the proposed Project Company will be established “as an independent, majority privately-owned and managed special purpose vehicle-joint venture with the objective of the deployment of 90,000 kilometres of climate-resilient fibre infrastructure following a phased approach, limited to provision of wholesale, open access services to licensed telecommunications operators, and management of associated investments, including the carrying out of preparatory activities and provision of transaction advisory services, and provision of equity financing in and capitalization of the Project Company.”

The Federal Government will participate in the company as a shareholder through the Ministry of Finance Incorporated, which manages the government’s investment interests. However, the agreement explicitly caps the government’s shareholding at a maximum of 49 per cent, ensuring that the company remains majority privately owned.

The $460m equity injection is broken into four tranches, tied to strict performance and operational milestones. The first tranche of $150m will be released once the Project Company is incorporated as a joint venture with private partners selected through a process acceptable to the World Bank, and after its memorandum, articles of association, and shareholding agreement are approved.

A second tranche of $100m will only be disbursed after the company adopts fiduciary and administrative procedures approved by the lender and completes at least 5,000 kilometres of fibre deployment. The third tranche of $100m is linked to the completion of an additional 20,000 kilometres of network construction.

The final tranche of $110m will be released after the company launches wholesale open-access services through a published reference offer and completes a further 40,000 kilometres of fibre deployment, bringing the total rollout to at least 65,000 kilometres before the final equity drawdown.

Once each tranche is withdrawn, the agreement requires that the funds be transferred to the Project Company’s dedicated account within five working days, showing the equity nature of the financing rather than traditional budgetary spending.

The project will be implemented under the oversight of the Federal Ministry of Communications, Innovation and Digital Economy, and the Federal Ministry of Finance will receive semi-annual progress updates.

A dedicated Project Implementation Unit will manage day-to-day execution, with overall financial management handled by the Federal Project Financial Management Department in the Office of the Accountant General of the Federation.

Beyond the fibre rollout, the project also includes technical assistance to federal government agencies to support the use of high-quality broadband in targeted areas, as well as funding for project management, monitoring and evaluation, environmental and social safeguards, grievance redress mechanisms and independent audits.

The agreement places strong emphasis on environmental and social standards, requiring compliance with an Environmental and Social Commitment Plan. It also mandates the establishment of an accessible grievance mechanism for affected communities and strict reporting obligations to the World Bank.

Court Dismisses N1Bn Suit against MTN, Awards N3m Costs

A Federal High Court in Lagos has dismissed a N1 billion lawsuit filed against MTN Nigeria Communications Plc by Walls and Gates Ltd and Okechukwu Udeichi, its managing director, over alleged copyright infringement, breach of confidentiality, and trademark violations arising from MTN’s 20th anniversary promotional campaign.

Court Dismisses N1Bn Suit against MTN, Awards N3m Costs

Delivering judgement on Tuesday, Justice Ayokunle Faji held that the plaintiffs failed to establish any legally protectable right in their proposal titled “20 for 20”, describing the action as frivolous, speculative, and vexatious.

The court dismissed the suit in its entirety and awarded N3m in costs against the plaintiffs.

The plaintiffs instituted the action under Suit No. FHC/L/CS/1935/2021, alleging that MTN unlawfully used their “20 for 20” proposal, which they claimed to have submitted to the telecoms company on 17 September 2019, ahead of MTN’s 20th anniversary celebration in 2021.

They argued that MTN’s anniversary promotion, in which 20 sport utility vehicles were given out to subscribers, emanated from their proposal and amounted to infringement of their copyright, confidential information, and trademark.

Based on those claims, the plaintiffs sought N1bn in damages or, alternatively, an order directing MTN to render an account of revenue generated from the promotion and remit 50 per cent of it to them.

MTN denied the allegations, contending that the proposal was an unsolicited business idea that imposed no contractual or confidential obligation on the company.

The telecoms firm maintained that its 20th anniversary programme was independently developed and that the plaintiffs’ document was merely a general business concept not protected under Nigerian copyright law.

MTN further argued that the plaintiffs lacked a valid registered trademark and failed to demonstrate access to or copying of any protected expression.

In resolving the dispute, Justice Faji noted that the plaintiffs conceded during oral submissions that they failed to prove their claim of trademark infringement, leaving only the issues of alleged breach of confidentiality and copyright infringement for determination.

On confidentiality, the court held that no confidential relationship existed between the parties.

Justice Faji observed that before sending the proposal to MTN, the plaintiffs had already submitted it to the Nigerian Copyright Commission and relied on it for a trademark application, thereby placing the document in the public domain.

The judge further noted that after transmitting the proposal to MTN, the plaintiffs admitted circulating it to other organisations, which extinguished any claim to confidentiality.

According to the court, MTN had no obligation to respond to an unsolicited proposal in the absence of a contractual, fiduciary, or business relationship, or a non-disclosure agreement.

On the allegation of copyright infringement, the court held that registration with the Nigerian Copyright Commission does not confer copyright, stressing that Nigerian law protects expressions, not ideas or business concepts.

Justice Faji ruled that the plaintiffs’ “20 for 20 Millennium Promotion” amounted to no more than an idea of rewarding customers during an anniversary celebration and lacked the originality and intellectual effort required for copyright protection.

He described the proposal as a bare business concept devoid of original qualities capable of attracting copyright. The judge also held that MTN’s use of the phrase “MTN 20th Anniversary” was a natural description of an anniversary event and did not originate from any protectable work of the plaintiffs.

He further relied on evidence showing that MTN affiliates in other jurisdictions had implemented similar anniversary reward ideas before the plaintiffs’ proposal.

Justice Faji characterised the suit as a “gold-digging exercise” aimed at forcing a commercial relationship on MTN. He criticised the plaintiffs for using MTN’s trademark in their proposal without authorisation and then seeking to ground a billion-naira claim on the same document, adding that the case wasted valuable judicial time.

While affirming that citizens should have access to the courts, the judge stressed that such access must be limited to suits with prima facie merit.

He therefore awarded N3m in costs in favour of MTN, holding that costs must follow the event.

The court accordingly dismissed the suit in its entirety and ordered the plaintiffs to pay the awarded costs to the defendant.
