Singapore’s telecoms regulator, the Infocomm Development Authority (IDA), has laid down strict 4G rollout targets for the city-state’s mobile operators, requiring that they provide coverage of more than 95% of outdoor areas from July this year, rising to over 99% in July 2017 and more than 99% of tunnels by July 2018. The IDA has announced its rollout guidelines amid growing calls for strengthened regulation, noting that by January 2019 it expects 4G licensees to have boosted in-building signal coverage to more than 85%. Furthermore, the watchdog says that any new network operators will also have to adhere to the new standards, although they will be given more time to deploy their networks.
