NTT DoCoMo, Japan's top mobile phone operator, said yesterday it had successfully completed a transmission experiment for fourth-generation (4G) mobile communications. The transmission, conducted in an indoor environment, allowed for a downlink of 100 Mbps and an uplink of 20 Mbps. Since 4G employs such a broad bandwidth, however, the service often degrades as secondary signals bounce off surrounding objects. DoCoMo said it plans to use a variety of technologies to avoid such problems. The current schedule calls for developing key 4G technologies by 2005, with commercial deployment in 2010.

T-Mobile Achieves 3 Gbps Using Standalone 5G in Mid-Band

Jun 14, 2022
T-Mobile has successfully tested 5G triple carrier aggregation (NR CA) using 5G standalone (SA) and mid-band spectrum, achieving an impressive downlink data rate of 3 Gbps. Triple CA is not new, but non-standalone (NSA) 5G requires that one of those three carriers be slower 4G, limiting potential data speeds.

T-Mobile Teams with SpaceX for Satellite Coverage Using Existing Phones

Aug 25, 2022
T-Mobile and SpaceX today announced a partnership to provide 100% coverage across the US and "vast" parts of oceans using SpaceX's next generation of Starlink satellites, which will be able to connect directly to existing cell phones. The service will use a dedicated "small slice" of the PCS band (the G block of band 25, which is 1910–1915 MHz for uplink and 1990–1995 MHz for downlink).
