Vodafone, MediaTek achieve 5G SA uplink speed of 277Mbps during trial in Spain
NEW DELHI: British telecom group
Vodafone
and Taiwanese chip company
MediaTek
have achieved an uplink of 277Mbps using the former's
5G
standalone (SA) network during a trial in Spain, to support the connectivity demand for user-generated content and a booming number of artificial intelligence (AI) applications.
The companies in a joint statement on Wednesday said while nearly 90% of the mobile traffic utilises downlink, the trend is now changing, as mobile users are increasingly uploading their videos and content online, necessitating faster uplink connections.
'We are continually improving the performance of our European networks to meet growth in traffic, a trend that's unlikely to slow down especially with the popularity of video sharing sites and cloud services, as well as AI applications in the near future,' said Marco Zangani, director of network strategy & architecture, Vodafone.
The trial, which happened at Vodafone's test facility near Madrid, Spain, utilised MediaTek's latest M90 modem. The chipmaker's processor delivers download speeds of up to 12Gbps and boosts uplink performance by up to 20% based on the latest 5G specification, Release 17, developed by 3GPP.
The companies were able to further boost the 5G uplink connection by using carrier aggregation to combine various spectrum channels.
Additionally, Vodafone and MediaTek used MIMO (multiple input, multiple output) antennas to transmit two data streams simultaneously from a single smartphone to the nearest mast, as well as tested it with the two key mobile data transmission methods – Frequency Division Duplex (FDD) and Time Division Duplex (TDD).
HC Hwang, general manager of wireless communication system and partnership at MediaTek, added, 'Enhancing uplink performance using groundbreaking technology will ensure next generation 5G experiences continue to support users globally.'
Currently, commercial smartphones do not yet support this feature, as they need uplink MIMO in FDD, but Vodafone and MediaTek said they aim to drive the development of compatible devices.

South Africa's SPAR plans to sell Swiss and UK retail businesses
HighlightsSouth Africa's SPAR Group is planning to sell its retail businesses in Switzerland and the United Kingdom after a strategic review of its European operations. The group is currently in exclusive talks with an unnamed established UK-based business regarding the sale of its UK operation, Appleby Westward Group. SPAR's Swiss business, which operates 300 stores, contributes approximately 16 billion rand ($899 million) to the group's turnover, while the South West England unit contributes around 6 billion rand. South Africa's SPAR Group plans to sell its retail businesses in Switzerland and in the United Kingdom after completing a strategic review of its European operations , the retail and wholesale group said on Thursday. The group, which owns several SPAR country licences of the Dutch SPAR group, has been trimming its international operations in order to "maximize the return on capital allocated". Last year it sold its loss-making Polish business. The group said it was in exclusive talks with an established UK-based business over the sale of its UK operation Appleby Westward Group . The potential buyer, which SPAR did not name, was "well positioned to develop and grow AWG in South West England," it said. In Switzerland, SPAR has been engaging established parties with extensive business interests in the region and experience in European food retail and distribution , it added. "The group approach has been to engage parties whose interests align with the growth ambitions of the local management teams and retailer partners, and will ensure continuity for employees, suppliers and customers," SPAR said. The Swiss business, with 300 stores, contributes 16 billion rand ($899 million) to group turnover, while the South West England unit contributes 6 billion rand. Internationally, SPAR will be left with Ireland , its biggest overseas business, and a joint venture in Sri Lanka .

AM/NS India launches two new patented steel products under Optigal
ArcelorMittal Nippon Steel India (AM/NS India) on Friday announced the launch of two products — Optigal Prime and Optigal Pinnacle — in its premium colour-coated steel portfolio, Optigal. With this launch, AM/NS India strengthens its position in the colour-coated steel market in India, introducing European-standard, highly corrosion-resistant steel for use in high-end infrastructure and construction projects such as state-of-the-art airports, railway stations, highways, and large buildings for the first time. Colour-coated steel is used in a variety of applications, primarily in construction, home appliances, furniture, and transportation. It is also popular for roofing, wall cladding, architectural facades, and interior decoration due to its durability, aesthetic appeal, and weather resistance. Major companies such as JSW Steel, Tata Steel, and Essar Steel are significant players in this sector. AM/NS is pioneering a new market segment in high-quality C4 specialty steel, previously unavailable in India, where it now stands as the sole domestic producer, said Ranjan Dhar, Director and Vice President of Sales and Marketing, at a press conference. The product will support Prime Minister Narendra Modi's call for accelerated development, which is key to achieving a Viksit Bharat. The steelmaker is targeting a dominant position in this segment and a 25 per cent share in the overall colour-coated steel market, Dhar added. The colour-coated steel segment in India, currently estimated at 3.4 million tonnes (mt), is growing at a sustained pace of around 10 per cent annually. The addition of two new specialised Optigal offerings will bring AM/NS India closer to its goal of securing 25 per cent of the market within the next two to three years, Dhar said. Optigal Prime is suited for urban and moderately corrosive environments, offering a 15-year warranty. Available in advanced finishes such as Silicon Modified Polyester (SMP), Super Durable Polyester (SDP), and PVDF, it is an ideal choice for roofing, cladding, and a range of other construction needs. Backed by a 25-year warranty, Optigal Pinnacle is designed for harsh industrial and coastal conditions, featuring high-performance PU/PA coatings that offer superior resistance to moisture, UV rays, and extreme temperatures — making it suitable for demanding applications such as airports, warehouses, and marine-facing buildings. AM/NS has already secured its first order, Dhar noted, although he did not disclose the order size. Six specialised variants of Optigal Prime and Optigal Pinnacle will be available — high gloss, anti-dust, anti-graffiti, anti-static, anti-microbial, and cool roof — catering to diverse requirements for high-performance steel solutions in India's rapidly expanding construction and infrastructure sectors. These variants have been developed using advanced zinc-aluminium-magnesium technology to deliver superior protection from corrosion and weathering — up to three times that of conventional coatings. As part of AM/NS India's commitment to the 'Make in India' initiative, these steel solutions have been designed with an eco-conscious approach — featuring low VOC emissions, no heavy metals or hexavalent chromium, and 100 per cent recyclability, making them an excellent choice for sustainable and future-ready construction. Optigal products are being manufactured at the company's state-of-the-art facility in Pune, Maharashtra. The company's colour-coated steel capacity currently stands at about 700,000 tonnes annually, with plans to expand to 1 mt soon. On exports of these products, Dhar said the company will first cater to domestic demand and then look at West Asian countries if opportunities emerge.
