Having announced the termination of its long-standing partnership with US-French vendor Alcatel-Lucent in August 2011, Switzerland’s Sunrise has teamed up with China’s Huawei to modernise its network infrastructure. Under the five-year deal, starting 1 September 2012, Huawei will assume operational responsibility for Sunrise’s infrastructure, though the telco will retain ownership. Further, Sunrise has launched a separate unit, dubbed TQ Net to oversee an extensive network expansion and improvement programme. TQ Net will upgrade Sunrise’s mobile infrastructure to allow maximum theoretical download speeds of 42Mbps. Branching into the 4G market, TQ Net will launch a trial Long Term Evolution (LTE) network later this year, with a full rollout planned in 2013. Also to better support its triple-play and IPTV packages, TQ Net will begin rolling out fibre-optic networks in selected cities; the telco did not specify a timeframe for fibre deployment, or name which cities would receive the upgrade.
