Thailand’s largest mobile operator Advanced Info Service (AIS) has rolled out the commercial Voice-over-LTE (VoLTE) services across 77 provinces in the country, says a release from the company.
The service will offer the users benefits like superior HD quality voice, lower background noise, faster voice call connection, and the ability to access the mobile internet simultaneously to a VoLTE call. At the initial stage, the VoLTE support will be available only on a limited range of smartphones including Samsung S7 EDGE, S7, S6 EDGE and S6. However, the service will be soon extended to other smartphone models.
Recently, the company upgraded its LTE network and is marketing it as 4.5G, claiming that the customers can now access connection speeds up to 550Mbps. Its LTE services are available across all 77 provinces. Its highest LTE-Advanced (LTE-A) speeds are based on 4×4 MIMO technology, Carrier Aggregation (CA) on 1800MHz and 2100MHz, and other technologies including LTE-U/LAA standards (Unlicensed-LTE / Assisted Access License). From April, the potential speed will grow up to 1Gbps.
In partnership with technology vendor Huawei, AIS will expand the commercial ‘4.5G’ service area in Bangkok and major provinces, especially in business/shopping centers. Although the highest speeds are currently supported on data-only devices (routers etc.), AIS is releasing a smartphone that supports its top ‘4.5G’ speeds in April.
