Reliable local stock of communications hardware
Find radios, cellular gateways, LoRaWAN nodes, Ethernet switches, modems and antennas that work in real South African projects - with fast access to stock, VAT invoices for procurement, and branch collection options. Communica carries broad lines for makers, students, technicians and procurement teams who need hardware today, not weeks from overseas. If you need components for campus networks, rural telemetry, or an industrial proof-of-concept, our Samrand warehouse and Cape Town branch shorten lead times and simplify logistics.
Why buy communications gear locally
Local purchasing reduces uncertainty: check stock and collect same-day from our Samrand head office or Pretoria and Cape Town branches, receive VAT invoices for institutional orders, and use account quotes for procurement workflows.

Specification callouts - what to check first
Before you commit, confirm these practical items: supported bands/frequencies, SIM slot count and carrier locking (for cellular gateways), antenna connectors and gain, power input range (PoE vs DC), environmental rating for outdoor kits, and supported interfaces (Ethernet, RS232/RS485, GPIO). For makers and students, look for development kits with clear pinouts, breakout headers and example firmware.
| Type | Key spec | Why it matters |
|---|---|---|
| Cellular gateway | Bands, SIM slots, VPN support | Ensure coverage and secure remote access |
| LoRaWAN node | Frequency (EU868/US915), range | Choose regional frequency and antenna |
| Wi-Fi AP | 802.11ac/ax, PoE | Throughput and simplified power wiring |
Compatibility example and quick calculation
Example: selecting a PoE Wi-Fi AP for a campus corridor. If your switch provides 30W per port and the AP draws 12W, you can power two APs from a four-port 60W injector by confirming the injector budget. Basic power calculation: Ptotal = V * I. For DC devices, use device-rated voltage and current from the datasheet to verify your PSU or PoE budget.
