Indonesian mobile operator XL Axiata has signed up eight million subscribers to its 4G network by early August 2016, reports IndoTelko, citing the cellco’s head of network planning Rahmadi Mulyohartono. XL Axiata, which launched LTE services in the country in December 2014, is reported to be working to improve quality and data access speeds over its fourth generation network via the introduction of 4-transmit-4-receiver (4T4R) technology, a development of 2T2R technology, which will particularly enhance indoor coverage. 4T4R was introduced in the cities of Bandung, Surabaya, and Denpasar last month, while the technology is expected to be expanded to Jakarta, Yogyakarta and Semarang in the near future. Further, XL Axiata plans to implement IP Multimedia Subsystem (IMS) technology to enrich its LTE network and ease future deployments of Internet of Things (IoT)-based services. The operator’s 4G network currently covers 86 districts via a grid comprising 5,358 base stations, with the cellco aiming to extend this coverage to an additional 100 towns and cities by the end of 2016.
