The process of GSM operators refarming their 1800MHz spectrum for 4G LTE has now entered the final round, with Telkomsel, Indosat, XL Axiata, and Tri Indonesia all working hard to complete the exercise on time. The latest works involve the areas of Bogor, Depok, Tangerang and Bekasi (Bodetabek), IndoTelko writes, with refarming expected to continue for the next two weeks in Jakarta. To date, refarming in no fewer than 40 of the total 42 clusters throughout Indonesia has already been carried out, with cellcos looking to minimise disruption by working through the night. Telkomsel and XL each hold blocks of 22.5MHz of 1800MHz of spectrum that is being reorganised under the plan, while Indosat has 20MHz and Tri 10MHz.
As reported by TeleGeography’s CommsUpdate, in April this year Jakarta-based telecoms industry watchdog the Indonesian Telecommunications Regulation Body (BRTI) warned that as many as 180 million mobile phone users in the country would be affected by the reallocation of 1800MHz frequencies between mid-April and 31 December 2015 – which it said would affect voice calls, SMS and data services that use either GPRS or EDGE technology on the cellcos’ systems.
