AIS subsidiary seeks 1800MHz LTE testing permission

14 Mar 2011

Digital Phone Company (DPC), a wholly-owned subsidiary of Thai mobile operator Advanced Info Service (AIS), has asked its build-transfer-operate (BTO) concession issuer CAT Telecom for permission to test 4G Long Term Evolution (LTE) mobile broadband technology, reports local new source The Nation. DPC, which leases an 1800MHz GSM network to AIS (the holder of a BTO concession from CAT’s sister telco TOT) under an October 2007 agreement, is planning to test LTE equipment from Huawei, ZTE and Ericsson, a source at AIS disclosed. Each vendor will require permission from the National Telecommunication Commission (NTC) before carrying out the tests, to be applied for in parallel to DPC’s request to CAT, the source added. DPC will reportedly set aside as much as 10MHz bandwidth for the 4G trial, out of its total 12.5MHz of allocated 1800MHz spectrum. The test will be run for 90 days on seven or eight base stations in Bangkok. Earlier, CAT’s CEO Jirayuth Rungsrithong had said that the state-owned telco wanted to evolve its HSPA service – not yet launched but currently being rolled out via a partnership with cellco True Move – to LTE ‘in the near future.’
