CSL’s 4G network just requires devices to launch

19 Oct 2010

Hong Kong cellco CSL announced yesterday that its dual-mode 4G/3.5G Long Term Evolution (LTE) and Dual Carrier (DC) HSPA+ network upgrade is ‘fully functional’ and is only waiting for devices to be available before launching commercially. As reported by Telecomasia, CSL has deployed DC-HSPA+ coverage in the 2100MHz band across the Special Administrative Region (SAR), and 2600MHz LTE in selected heavy-traffic districts; CSL is also deploying 1800MHz LTE equipment. The object of deploying both LTE and DC-HSPA+ at the same time, according to CSL’s CTO Christian Daigneault, is to offer a fallback option for LTE without resulting in a noticeable drop in connection quality, due to the 42Mbps maximum theoretical downlink speed achievable with the Dual Carrier configuration. He added that the extra speed will be important for applications such as HD and 3D video, online games and videoconferencing.’ CSL gave journalists a demo tour of its LTE network yesterday, using LTE USB modems to access HD videoconferencing, HD video downloads, online games and 3D video, in locations from the urban canyons of Central and Tsim Sha Tsui to the remote village of Sai Kung in the New Territories.
