Vodafone and chip firm MediaTek say they have reached a milestone by successfully testing 5G uplink speeds of up to 277 Mbps.
Vodafone and MediaTek used the former’s 5G Standalone (5G SA) network at its test facility near Madrid, Spain, with MediaTek’s M90 modem for the trial. MediaTek’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 industry body 3GPP, so says the release.
A further boost the 5G uplink connection was achieved by using carrier aggregation to combine various spectrum channels, as well as MIMO (multiple input, multiple output) antennas to transmit two data streams simultaneously from a single smartphone to the nearest mast.
