Today, AIS has introduced its smartphone that supports LAA on the 4.5G network. The LAA-enabled smartphones include the Samsung Galaxy S9, Samsung Galaxy S9+, and Sony Xperia XZ2 Premium. Data on these LAA smartphones is two times faster and downloads 30 percent faster than on the 4G network, AIS said. Serviceable areas for the 4.5G network includes Bangkok, key cities, and areas with high data usage such as Siam Center and The Mall Korat.
AIS will start to gradually upgrade its firmware through FOTA, onto Samsung Galaxy S9 and Samsung Galaxy S9+ devices in July. Users will receive an on-screen notification to update their software. Following this update, customers will be able to use the MIMO 4×4 technology with CA, 256 QAM, and LAA in serviceable areas. Settings do not need to be adjusted. Sony Xperia XZ2 Premium will soon be in stores.
