Of course, much of it boils down to the spectrum they bought at auction and on the secondary markets: Verizon in one corner with a stash of millimeter wave (mmWave) spectrum, and T-Mobile in the other with vast holdings of 600 MHz and – through a very public two-year battle to merge with Sprint – all of Sprint’s 2.5 GHz spectrum. T-Mobile also holds mmWave spectrum and Verizon has lower-band spectrum, but those are not, currently, the biggest stars of the show.The reason Verizon continues to be bullish on mmWave is it’s a differentiator, she explained. Some 5G deployments aren’t as good as 4G, and that happens due to the spectrum that’s being used and how the network is engineered. “For us, we wanted 5G to really be the ‘G,’” or the generational change. “It’s got to be something different and that’s what we’re deploying.”During his appearance at the same conference a day prior, T-Mobile President of Technology Ray said his competition, especially Verizon, is forced to rely on DSS to bring broad 5G coverage to customers, but DSS also means limited capacity. “Our strategy is to build 5G with free and clear spectrum and utilize DSS as another tool in our toolbox, deploying only where it makes sense,” he said.T-Mobile started in a completely different place, with low-band spectrum for 5G. “Now everyone is playing catch-up and embracing the layer cake approach that we pioneered,” he said. Millimeter wave has its place, but given the economics and physics, “you don’t build a large-scale 5G network with it. You build 5G with a low-band, broad connectivity layer,” which is what T-Mobile is doing with 600 MHz, where it’s getting peak speeds of 1 Gbps. On top of that is its layer of mid-band 2.5 GHz spectrum.“I’ve been at T-Mobile for 20 years, and we’ve never had such a strong spectrum position, and now we have the resources we need to fulfill our promise of accelerating the delivery of meaningful 5G,” he added. Thanks to the combination with Sprint, the new T-Mobile controls 319 megahertz of sub-6 GHz low and mid-band spectrum nationwide, which is nearly double that of AT&T and nearly triple that of Verizon. T-Mobile also has more than 1,100 megahertz of mmWave spectrum, which is more than AT&T, he added. -- ???????? | |||
