Why buy-communications gear from Communica?
When a project needs reliable RF, mesh networking or cellular backhaul, delays cost time and prototypes. Communications offers immediate access to a wide selection of communications modules and accessories held locally, so you can move from idea to working prototype faster. Benefit-driven services like branch pickup, VAT invoices for institutions and account quoting for procurement make purchasing easier for students, technicians and engineering teams across South Africa.
What we stock and who it's for
From LoRaWAN gateways and WiFi modules to LTE modems, antennas and radio modules, our ranges suit makers building prototypes, tertiary labs teaching wireless systems, and field technicians deploying telemetry. Popular brands and categories include development boards, cellular modems, LoRa nodes, Zigbee components and antenna kits-find these in our Collections and browse by brand to compare options.
- Makers & students: low-cost dev boards, breakout shields and antenna packs.
- Engineers & technicians: rugged modems, industrial gateways and certified connectors.
- Procurement teams: ability to request quotes, collect VAT invoices and schedule branch pickup.

Specification callouts to watch for
When selecting communications hardware, focus on these critical specs to ensure the part fits your application:
| Spec | Why it matters | What to check |
|---|---|---|
| Frequency / Band | Regulatory and propagation effects | Local ISM bands (e.g., 868 MHz LoRa) or cellular LTE bands used in South Africa |
| Antenna gain | Range and link budget | Match antenna connector type and expected coverage |
| Power consumption | Battery life and heat management | Transmit current, sleep modes, and PSU headroom |
For more categories and parts, you can browse our full collections page to compare modules, antennas and gateways: Collections (Shop by Category). If you prefer to review individual product lines by vendor, visit our Shop by Brand page to see which brands we stock: Shop by Brand.
Compatibility and accessory bundles
Compatibility typically depends on connector types, voltage levels and supported bands. We routinely bundle starter kits that pair dev boards, antennas and power supplies so you get a working test setup out of the box. When specifying accessories, confirm SIM form factor for cellular kits, SMA versus RP-SMA for antennas, and voltage for modems to avoid mismatches.
