CSL confirms plan to launch dual-band 1800MHz/2600MHz LTE

23 Jul 2010

Hong Kong-based cellco CSL and its Chinese equipment partner ZTE have confirmed a plan to deploy what they expect to be the world’s first commercial 1800MHz/2600MHz dual-band Long Term Evolution (LTE) mobile broadband network in Hong Kong. The announcement follows the signing of a commercial LTE network construction contract, under which ZTE will provide CSL with an end-to-end 4G infrastructure solution and LTE devices; the vendor will also supply a unified core network to support 2G/3G/LTE concurrently. According to TeleGeography’s GlobalComms Database, in November 2009 CSL and ZTE opened an LTE technology centre in Kowloon Bay, before launching user trials over a 4G network, and in April 2010 the cellco revealed that it would be in a position to launch commercial LTE services by the end of the year, although an actual date for going live has not been announced. The partners are testing LTE in both the 2600MHz and 1800MHz bands, with CSL previously stating that LTE in the latter frequency range would be deployed at a later date to 2600MHz services. CSL CTO Christian Daigneault told Telecomasia that operating LTE in dual bands would improve indoor coverage and provide extra capacity for more stable connections in high broadband traffic areas. He added: ‘Another advantage is that for LTE sites installed in-building, LTE at 1800MHz can re-use the existing GSM cabling … This will accelerate the availability of LTE in all indoor locations in the future.’
