Singapore fixed and mobile operator StarHub has announced a multi-million dollar capital expenditure programme designed to improve its mobile networks in the city-state. The carrier says the improvements include deploying higher capacity 3G and 4G base transceiver stations (BTS), upping its backbone capacity to handle extra traffic, and the possible implementation of femtocells to further augment coverage. Further, StarHub’s 3G infrastructure is the first in Singapore to utilise the 900MHz band for 3G, with a view to minimising dropped call rates, boosting in-building signal quality and again, increasing capacity. As part of this plan, the operator says the total number of 3G-enabled BTS on its system will increase by ‘more than 40%’ by December 2013, while the 4G network – which currently covers 75% of the island – is on course to reach 95% street-level coverage by October this year. By that date it hopes to join rivals M1 and SingTel Mobile in providing nationwide coverage for ultra-high speed mobile internet services.
