CEO Dirk Wössner's "5G" claims are now meaningless. DT is now using DSS and calling connections "5G." Since the actual speed is about the same as 4G, that proves the industry definition of "5G' is now meaningless.
It's so slow - and the latency so high - DT refuses to provide figures. Verizon President Ronan Dunne has a similar offering, but explains, "The lower down the spectrum tiers you go, the more that will approximate to a good 4G service." That's what DT is now selling, a good low-band 4G service.
Until now, DT had said it would bring 5G to 20% of Germany by the end of 2021. It didn't consider low-band "5G," even though it uses 5G NR software.
DT has changed its actual network and capex plans. It changed what it considered 5G to the 3GPP marketing dream or anything that runs "5G NR" software. The software has only a minimum effect on the performance of below 2.5 GHz - 19% or probably less. DT is providing no figures, but its new 5G is going to be slower than some available 4G.
