As reported, International Telecommunication Union (ITU), under the United Nations, will hold a conference next month in Egypt to finalise use of 26 GHz band for 5G services. It will start deliberation for the same this month.
At present, the Department of Telecom has accepted the demand of ISRO to use 26 Ghz band, in which 5G ecosystem has been developed, primarily for satellite service. Consequently, the department has submitted this proposal for consideration to the ITU, which sets global benchmark for wireless services. The proposal allows use of 26 Ghz band for mobile services with conditions to ensure that the 5G services will not interfere with satellite operations.
DoT said: "The operation of IMT (International Mobile Telecommunications) within the frequency band 24.25-27.5 GHz shall protect the existing and future SRS/EESS earth stations; the operation of IMT within the frequency band 24.25-27.5 GHz shall protect the existing and future FSS earth stations."
The DoT has proposed radiation power of 7 decibel watt per 200 megahertz for base stations to be deployed in the 26 Ghz band against industry estimate of 33 dbW per 200 Mhz band.
COAI Director General Rajan S Mathews said: "The power condition per base station proposed by the government is lower than that used for wifi hotspots. It will be very difficult to transmit voice at this limit."
