T-Mobile: Uplink is the next big thing

T-Mobile just upped the ante on 5G upload speeds, announcing that it set a new uplink speed record of 550 Mbps using 5G Advanced technology. Why is it significant? According to T-Mobile President of Technology, Ulf Ewaldsson, “uplink is the next big thing.” Others tend to agree, as the industry is increasingly putting more focus on uplink after years of concentrating on the downlink. The uplink comes into play more as consumers upload videos to social media, play games in real time, and (we expect) use AI on their phones. T-Mobile used 100 MHz of TDD spectrum at 2.5 GHz (n41) and 35 MHz of FDD spectrum (n25) around 1.9 GHz to achieve the record-breaking 550 Mbps total speed. The test was conducted using a MediaTek smartphone flagship test device with an integrated M90 modem.
