Hong Kong's operator CSL and ZTE have announced the deployment of LTE Advanced 300 Mbps cell site in a commercial network at the Mobile World Congress 2014, Barcelona. CSL is also collaborating with Qualcomm and ZTE on testing a new LTE Advanced CAT6 modem using the Qualcomm Gobi 9x35 chipset, which is expected to be available commercially by the second half of this year.   

CSL has combined its existing licensed 20 MHz LTE carrier at 2600 MHz with another licensed 20 MHz LTE carrier at 1800 MHz, to achieve a maximum theoretical speed of 300 Mbps. 

CSL plans to introduce LTE-A300 commercially in the second half of 2014 when devices are expected to be available. After announcing the network launch of Voice over LTE (VoLTE) in December 2013 in its network, CSL also intends to proceed with full commercial launch in the first half of 2014 when device and service are mature.
