Tele2 's press release today announces that Tele2 and Radio Research Institutes are launching tests of LTE technology simultaneously with GSM in the 1800 MHz band in Omsk mobile network using equipment supplied by Nokia Siemens Networks.
I consider it appropriate to assume that we are talking about the joint testing of LTE and GSM, which was discussed in December 2011 , and before that in November : the results of the tests, if they are successful, should in practice confirm the compatibility of LTE and GSM in the same range and reinforce the principle of technological neutrality, although Minister Schegolev doubted in several interviews in September 2011 in several interviews.Source: https://habr.com/ru/post/139873/
