LoRa® or Long Range modem, provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption.
Example unit Semtech SX1276 : Packet engine up to 256 bytes with CRC. Programmable bit rate up to 300 kbps.
LoRa® modems have Excellent blocking immunity and are a perfect match for IoT.
Here @ Switched On Scotland we have decided to dump LoRaWAN because of its poor security design.
We however make the very large distinction here as LoRa modems are very much a good fit for IoT.
The designing company has had the vision to back this technology, hats of for this.
LoRaWAN was let down by the designers of SECURITY so the system could be spied on easy.
You just need access to one database with all the AES keys, FOOLS!
LoRa® modems can work in a peer to peer setting. This means two modems can be set-up to talk without any other hardware.
This is a great place to start when looking at LoRa® for your IoT projects.
Hardware can be found in the form of Arduino SX1276 / SX1278 Module DRF1278F for £10.
LoRa® modems can be made to work with a single channel gateway.
Here a little more design is required to handle multiple clients.
The benefits of not using a SX1301 powered gateway are cost related only.
