Hong Kong cellco CSL has announced that its two main brands, 1O1O and One2Free, have enhanced the performance of their 4G LTE mobile broadband services after switching on an additional 2×5MHz of 1800MHz band LTE frequencies across ‘most of the network’, expanding active 1800MHz LTE bandwidth to 2×15MHz. CSL plans to continue expanding in-use 1800MHz LTE spectrum to 2×20MHz ‘across the entire territory by 2014’, further augmenting the speed and capacity of its dual-band 4G services, which also utilise 2×20MHz in the 2600MHz band. TeleGeography notes that CSL is refarming its existing 1800MHz spectrum from its original application in the cellco’s 900MHz/1800MHz 2G/2.5G GSM/GPRS/EDGE network, whilst some 900MHz spectrum has been refarmed to 3G/3.5G W-CDMA/DC-HSPA+ network services.
