For the first time, T-Mobile has won the title of Fastest Mobile Network in PCMag's annual nationwide drive test. T-Mobile's 5G network was the fastest in 24 out of 36 tested cities and regions. PCMag attributes the win to T-Mobile's use of mid-band spectrum (band 41, around 2,600 MHz) for 5G. This unique frequency band was originally owned by Sprint, and T-Mobile has been aggressively re-deploying it for 5G since merging with Sprint. Mid-band frequencies are ideal for 5G, offering a good balance of coverage and potential data speeds. AT&T and Verizon recently purchased C-band spectrum that will let them deploy mid-band 5G networks like T-Mobile starting by the end of this year. Verizon's "Ultra Wideband" mmWave 5G network is the fastest 5G network, but has very limited coverage. AT&T and Verizon's sub-6-GHz (non-mmWave) 5G networks are often barely faster than 4G. Looking only at 4G networks, AT&T was once again the winner.
