(Telecompaper) Brunei Darussalam, Indonesia, Malaysia and Singapore have pledged their commitment to align with the Asia Pacific Telecommunity 700 MHz band plan. The plan aims to align and optimise the use of the freed broadcast spectrum after the analogue switch-off, allowing greater flexibility for the deployment of mobile broadband services using technologies such as 4G. The harmonised use of the 700 MHz band for mobile broadband uses will improve regional mobile roaming and provide more competitive mobile broadband services.
