About GRID Communications

Company Profile

GRID Communications Pte Ltd (GRID) is the leading public telecommunications walkie talkie network operator in Singapore. It is the only public trunked radio operator that provides island-wide coverage with more than 300 base stations over Singapore.

GRID Communications (formerly known as Digital Network Access Communications) is a joint venture incorporated in December 2000 between Singapore Technologies Telemedia and Singapore Telecom Ltd each owning 50% equity stake in the company. IMDA has granted GRID Communications the license to provide facilities-based operations (FBO) under Section 5 of the Telecommunications Act (Chapter 323) since 1 November 2000. 

GRID Communications presently uses Motorola’s Integrated Digital Enhanced Network (iDEN®) technology which combines communications services that previously required several devices. These services include Push-To-Talk (PTT) two-way radio, cellular service, wireless data, and text messaging. It operates a fully integrated digital wireless communications service under the brand “GRID”.

To date, GRID has invested over $180 million in network infrastructure. GRID’s network was designed to provide reliable and secure communications throughout Singapore with an advanced core switch of high reliability. GRID provides superior outdoor coverage with several hundred base stations deployed island-wide and has invested heavily in providing in-building coverage to major commercial centres and strategic buildings, such as Singapore Expo, Suntec City, Singapore Changi Airport, Port Authority of Singapore, Sentosa, Ngee Ann City and several others, within Singapore.

GRID’s mission is to provide value with our advanced wireless radio services of superior quality and reliability efficiently to all our customers. GRID has established itself as a dominant and reliable business partner to major companies, serving over 2000 large, medium and small enterprises with approximately 70,000 users in Singapore.
