We began by offering installation and maintenance services, as well as improving the quality of GSM (2G) mobile phone signal systems and transitioning to 3G, 4G, and now 5G technologies. We have observed the rapid pace of network upgrades over the past few years and have recognized the opportunity to adapt these technologies for the Thai market. Since 2018, we have been developing hardware and software to support 5G, and now have a wide range of related products available for actual use.
