By siliconindia | Wednesday, 05 May 2021, 03:30 Hrs The Department of Telecommunications (DoT) has permitted telecom service providers (TSPs), including Bharti Airtel, Reliance Jio Infocomm, Vodafone Idea, and MTNL, to conduct 5G trials. As largely anticipated, Chinese tech majors such as Huawei and ZTE have not been allowed to participate in the trials. An official statement said that the TSPs have tied up with original equipment manufacturers and technology providers -- Ericsson, Nokia, Samsung and C-DOT. In addition, Reliance Jio Infocomm will also be conducting trials using its own indigenous technology. The permissions have been given by the DoT as per the priorities and technology partners identified by TSPs themselves. The experimental spectrum is being given in various bands which include the mid-band (3.2 GHz to 3.67 GHz), millimetre wave band (24.25 GHz to 28.5 GHz) and in sub-Gigahertz band (700 GHz).
