Telkomsel announced that it has successfully conducted the Operation Feasibility Test on the 2.3GHz TDD (Time Division Duplex) technology that can strengthen and maximize the quality of its 4G LTE service for its customers.
2.3 GHz LTE TDD can provide better downlink throughput services, due to the large bandwidth used. The additional spectrum also allows Telkomsel especially in areas where the capacity of data services is dense.
With a higher speed of mobile broadband access, Telkomsel is able to deliver the best digital lifestyle experience for all Indonesians, and customers are increasingly comfortable in accessing mobile information, especially video streaming services.
Currently LTE TDD BTS supporting 2.3 GHz TDD service is gradually deployed in Jabodetabek area which has high data service density level. The Operator targeted to deploy as many as 500 BTS LTE TDD not only in Jabodetabek but also in Palembang and Bandung by mid December 2017.
Early this year, LTE TDD BTS will be deployed to target other cities across Indonesia that have high data service density level.
To be able to enjoy this 2.3 GHz TDD LTE service, customers do not need to replace simcard as long as the device used is already able to support 2.3 GHz LTE TDD frequency band and is in 2.3 GHz LTE TDD service coverage. Currently from around 50 million LTE devices in Telkomsel network, about 85% of them have been able to support this service.
The frequency allocation composition of Telkomsel is as follows: 2.3 GHz frequency with 30 MHz bandwidth, 2.1 GHz frequency with 15 MHz bandwidth, 1.8 GHz band with 22.5 MHz bandwidth, 900 MHz frequency with 7.5 MHz band width, and 800 MHz frequency with 7.5 MHz bandwidth.
