Dtac to test 4G VoLTE for first time in Thailand

The company said today that the initial testing would start with Dtac employees who own 4G VoLTE-enabled devices, which include Samsung S6, S6 Edge, and Dtac Eagle X smartphones. Test results will be collected and analysed to improve service quality prior to public testing and commercial launch.

Prathet Tankuranun, chief technology officer, Total Access Communication, said that the technology would extend Dtac's 4G high-speed network. It would offer HD-quality voice service and is expected to replace legacy 2G and 3G services within the next 3-4 years. The new 4G VoLTE technology will a;sp allow simultaneous voice and data use on 4G, which is different from today where data service operates on 4G and voice on 2G/3G. 

The 4G VoLTE technology allows customers to experience HD-quality voice service and 10 times faster call setup times, decreasing from 5 seconds to 0.5 seconds. It can deliver HD video calls with resolution up to 720P/1080P, which offers much better image quality and detail than the current network. T

The company has launched its 4G services in more than 40 cities in Thailand to support mobile internet demand.
