In the strongly-worded post he suggests AT&T and Verizon's lack of vision on the future of 5G and blasts their attempts at confusing the mobile industry because of their "lack of transparency and outright lies about 5G" and "same old deceptive practices, limited availability and higher prices".
AT&T comes under fire for calling itself a "world leader in 5G" when, in fact, consumers aren't yet able to sign up for the service. It doesn't end there though. It also receives flack for limiting the sale of the Galaxy S10 5G to businesses and developers only. He also tells consumers to not be fooled by the 5GE logo AT&T now uses.
The reason is that 5GE actually means "5G Evolution" and is based on 4G LTE technology. You can think of it as an enhanced version of 4G LTE, not true 5G. 5G uses an entirely different type of radio wave that allows a lot more data to be transferred quickly.
Verizon, on the other hand, is wrongly focused solely on mmWave which has "well known limitations", according to Legere. These include a mmWave having a short range and being easily disrupted by physical obstacles like trees, windows and doors.
All this leads to Legere explaining why T-Mobile is different and why its 5G is the "Real 5G". The reason why T-Mobile's 5G is better than the others, according to Legere, is because it will have a range of low, medium and high 5G spectrums. That is if regulators approve the merger with Sprint, which has the crucial 2.5 GHz mid-band spectrum T-Mobile still needs.
With 5G expected to enable a host of new technologies like autonomous vehicles, smart cities and next-generation smart home products it's understandable why the competition, and language, is hotting up.
