China’s Huawei Technologies has provided details of its partnership with Sri Lanka’s largest cellco by subscribers, Dialog Axiata, to roll out a 4G Time Division Duplex Long Term Evolution (TD-LTE) wireless broadband network across the country. The first of the network’s two planned phases was completed on 31 December 2012, with the launch of commercial services in the capital Colombo on that date, and expansion to major cities and towns across the country is planned ‘soon’. Dialog, via its broadband and fixed line division Dialog Broadband Networks (DBN), chose Huawei’s end-to-end solutions for radio access networks (RAN) and evolved packet core (EPC) alongside Huawei’s application software and customer-premises equipment (CPE). The TD-LTE network will also host VoIP services and VPN solutions aimed at small-to-medium enterprises (SMEs) and residential users; Huawei said that its VPN solution offers end-to-end management with precise charging and centralised VPN subscriber management, and also supports transparent transmissions on an LTE network to complement or act as a substitute for traditional fixed lines. Dialog is currently selling LTE connections as a fixed broadband service alongside its fixed WiMAX services, whilst offering mobile broadband over its 3G W-CDMA/HSPA network augmented with GPRS/EDGE coverage. Sri Lankan rival Mobitel announced at the end of 2012 that it was launching a mobile LTE network based on Frequency Division Duplex (FDD).
