Gateways

slide-13
SLIDE 13

Gateways

  • Gateways are packet forwarders
  • They “forward” LoRaWAN packets to TCP/IP using

WiFi/Ethernet/Cellular

  • They operate on different frequency bands, depending on

the region (pay attention!)

  • Once you buy/build a gateway, there is not much to do!
  • You simply need to register your gateway in TTN

Do I need a gateway?

You don’t need to install a Gateway to use TTN if there are gateways available in your area!
