Global Communications is the sole supplier of the Rohill TetraNode in South Africa and Africa.

TetraNode, manufactured by ROHILL, is an IP based system and is a 100% compliant TETRA system featuring a multi-protocol air interface capability and is based on a digital backbone of interconnected TetraNode eXchanges (TNX). The system architecture is proven in practice and systems are scalable from single site to nation wide. The effort for setting up a TetraNode system is minimal. It utilises "plug & play" functionality enabling rapid network rollout. TetraNode uses distributed and multi level network management. 

Each TetraNode eXchange  is capable of serving 256 voice channels over max. and up to 16 base station sites. Each base station site offers interconnectivity to PABX/PSTN. Connections between a site and a TetraNode eXchange are digital, using V.11, ISDN or G.703. For larger systems TNX Compact PCI is used for up to 16320 base stations.
TetraNode is especially designed for digital radio trunking network applications in the safety and security related market. It includes a full range of redundancy and fallback features essential for this specific market segment. 
The TetraNode Network Management System (NMS) tool, a Windows client-server application that may connect to the nearest TetraNode eXchange, allows for total network or partial provider access.
