Taiwan’s Ambit Microsystems has confirmed that it will launch commercial 4G services on 15 May 2015, Digitimes reports. With Ambit having agreed to pay TWD9.18 billion (USD312 million) for spectrum in the 700MHz and 900MHz frequency bands back in October 2013, it subsequently acquired a 4G operating license from local regulator the National Communications Commission (NCC) in December last year. However, the introduction of a commercial service has, however, been hindered by the proposed merger of Ambit with one of the nation’s existing operators, Asia Pacific Telecom (APT). With regulatory authorities having yet to approve the tie-up – Ambit and APT have agreed to defer the planned merger until 31 December 2015 – under the terms of its concession Ambit is required to begin operations before 3 June 2015 in order to retain its licence. No details regarding the initial areas in which the new player will offer coverage were mentioned.
