Radio is a different problem from telephony
Two-way radio and business telephony solve genuinely different problems, which is why this listing does not pretend to be a phone-system page. Radio is for instant, one-to-many, push-to-talk communication that has to work when everything else does not: a mine underground, an airport apron, a utility crew in a fault, a public safety response. TETRA and DMR networks are engineered for that, with intrinsically safe handsets, encryption and direct-mode operation when infrastructure is out. None of it replaces a PBX and a PBX does not replace any of it. If you need business phones, compare the verified providers.
Who Global Communications is a fit for
- Mining, utilities and aviation operations needing intrinsically safe, rugged radio
- Public safety and critical infrastructure users requiring TETRA with encryption
- Organisations replacing analogue radio with DMR or NXDN digital systems

Does Global Communications sell phone systems or internet?
No. It supplies professional two-way radio — TETRA, DMR, NXDN and HF systems and terminals — for organisations needing push-to-talk communication.
Who owns Global Communications?
It is a member of Hudaco Industries, a JSE-listed South African group specialising in the importation and distribution of branded industrial, automotive and electrical products.
What is TETRA?
A digital radio standard built for mission-critical use, with encryption, group calling and direct-mode operation that keeps radios talking to each other even when network infrastructure is unavailable.
Which brands does it carry?
Sepura TETRA terminals, Rohill TetraNode network infrastructure and Barrett HF communications equipment.
Would radio replace our office phone system?
No. Radio handles instant push-to-talk between staff on the move or on site. A phone system handles calls to and from the outside world. Most organisations that need radio also need a phone system.
