Taiwanese multi-service operator Chunghwa Telecom has selected Finnish vendor Nokia Solutions and Networks (NSN) as a supplier for its Long Term Evolution (LTE) network, which it aims to launch commercially in 2014. Under the terms of the contract, NSN will implement an LTE Radio Access Network with its Flexi Multiradio Base Stations. As another part of the radio access deal, NSN has confirmed it will enable voice services for LTE smartphone users with its circuit-switched fallback (CSFB) technology, which allows an LTE handset to ‘fall back’ to a 3G network to complete circuit-switched calls and SMS alongside LTE mobile broadband data services. NSN will provide its full turnkey solution for network deployment, while the deal also includes network planning and optimisation, system integration, technical consultancy and care services.
Further, alongside the LTE announcement it has also been confirmed that Chunghwa has extended an existing contract with NSN under which the latter acts as the sole supplier of the operator’s island-wide HSPA+ network in order to further increase network capacity.
Commenting on the developments, Kuo-Feng Lin, president of Chunghwa’s Mobile Business Group, was cited as saying: ‘We are launching the LTE network to meet the ever-increasing subscriber expectations for fast-speed mobile broadband. Having a reliable vendor with an excellent track record to support our ambitious roll-out target is crucial for us … Our successful collaboration with NSN dates back almost 15 years, starting in 1999 with the deployment of our 2G GPRS core network and evolving over the years to 3G and now 4G.’
