Motorola Solutions reports that it is upgrading the analogue radio network of Thailand’s CAT Telecom to a TETRA (Terrestrial Trunked Radio) digital network and optimising its spectrum usage, in cooperation with local partner Samart. The upgrade will be carried out in phases, starting with the introduction of ‘a few thousand’ TETRA subscriber radios and base stations and a switching centre to build a digital network covering Bangkok Metropolitan Area and the Eastern Sea Board industrial hub. Target users of the network include the oil/gas sector, transportation operators and other government and enterprise users for whom robust mission-critical grade communication is essential. CAT’s existing ‘Smartnet’ analogue network – also provided by Motorola – was designed for the use of multiple government agencies and enterprises. The TETRA implementation is based on Time-Division Multiple-Access (TDMA) technology to deliver audio clarity, extended range, integrated data applications, a high level of security, and data applications such as text messaging, location tracking and dispatch capability in a cost-effective way for enterprises.
