Telecoms regulator Ofcom has proposed boosting the maximum permissible base station transmit power for 3G and 4G mobile broadband services to increase both capacity and coverage.
Under the plans, it will increase the power in the 1800MHz radio spectrum band for both UMTS (3G) and LTE / WiMAX (4G) mobile and broadband voice services by +3dB, after receiving requests from EE,Three UK, O2 and Vodafone.
According to the regulator, the 3dB will have significant positive effects on coverage, capacity and the ability to penetrate deeper into buildings.
This, in turn, will provide "flexibility to coverage and traffic management, load balancing and efficient handovers between different network layers", Ofcom says.
A consultation on the change has now been opened by the regulator, though it has assured industry members that allowing a higher maximum permitted base station transmit power will not have a negative impact on competition or other spectrum use.
