Management said T-Mobile’s median network speeds were approximately 60% to 70% faster than those of its two largest competitors and cited an Opensignal global 5G coverage award.

T-Mobile reported a fivefold increase in traffic over the past five years of its 5G rollout, while speeds more than doubled. It identified radio uplink capacity in dense, busy sectors as an area to monitor and cited 5G Advanced uplink features and spectrum depth as ways to address that demand.
