Spectrum Clash: Airtel vs Tejas Sparks Network Interference Debate
The dispute between Bharti Airtel and Tejas Networks over network interference in Rajasthan highlights spectrum‑allocation issues by the Department of Telecommunications (DoT). Narrow “guard bands” between spectrum blocks assigned to Airtel and BSNL caused signal overlap despite compliant equipment. Tejas maintains its radios meet standards and installed additional filtering on around 1,000 BSNL sites, but the core issue lies in regulatory planning rather than hardware.
ZTE Powers the World’s First Ultra-Fast 5G-A Network for High-Speed Rail
ZTE, in collaboration with China Telecom and China Unicom, has launched the world’s first 5G‑A (advanced 5G) network for high-speed rail, transforming in-train connectivity. Using a “co-build, co-share” infrastructure model, deployment costs drop by over 50 percent, while combining 200 MHz (3.5 GHz) and 40 MHz (2.1 GHz) spectrum to create a 3-carrier-component network. This delivers peak speeds exceeding 1 Gbps per user and average downlink above 150 Mbps, even on fast-moving trains. Integrated AI and 5G‑A capabilities optimize resource allocation, supporting high-quality video, cloud gaming, streaming, and work-related use, significantly enhancing passenger experience and network efficiency.
Samsung and SK Telecom Team Up to Power the 6G Revolution with AI‑Driven Networks
Samsung and SK Telecom have partnered to drive 6G innovation through AI‑powered radio access networks (AI‑RAN). The collaboration focuses on AI‑based channel estimation, distributed MIMO transmission, AI‑RAN schedulers, and smarter core‑network architectures to enhance speed, reliability, and efficiency. Samsung will lead AI and network‑software development, while SK Telecom provides real‑world data and testing infrastructure.
