Description:

The LoRa Raspberry Pi 4 Gateway is a professional grade gateway with the hacker in mind. While other low cost gateways are a single channel, the LoRa Raspberry Pi Gateway comes with a fully assembled with a heat-sinked concentrator capable of multi-channel, multi-node communication all running in a friendly, hackable Raspberry Pi environment.

LoRa is a fantastic advancement in the field of wireless communication. The multi-kilometer distances are incredible! Point to point LoRa has been nailed down with various low cost Semtec based modules like the RFM95 but the true power of an open IoT network is LoRa gateways. These provide public access accross the globe to any LoRa node as long as the node follows the guidelines (don't use more than your share of bandwidth). But what gateway do you need?

The LoRa Raspberry Pi Gateway uses the high-power multichannel Semtech SX1301 RF processing engine specifically designed for LoRa gateways. If you're just experimenting with LoRa, a single channel gateway is a fine way to go; we offer the ESP32 1-Channel LoRa Gateway based on the SX1276/78 RFM95 module. But if you're planning on having multiple, public LoRa nodes you'll need a proper gateway like the LoRa Raspberry Pi Gateway. It is capable of receiving up to 8 LoRa® packets simultaneously sent with different spreading factors on different channels.

Designed for the US and Australia, the 915MHz LoRa gateway comes with a black anodized aluminum enclosure designed for use with the Raspberry Pi 4. With this upgraded model you no longer need to provide your own microSD card (16 GB card included) & there are handy instructions on flash the LoRa Gateway image to the MicroSD card. We recommend using Resin to create your Linux image. The gateway includes a 2dBi 868MHz antenna and a multi-frequency GNSS(GPS) antenna. If you'd like to increase the LoRa range we have 2dBi 1/2 wave and 6dBi antenna upgrades available.

Overall, this Gateway has various functionalities that are ideal for prototyping, proof-of-concept demonstrations and evaluation on future deployment scenarios. With its ready to use Raspbian based firmware, it is now possible to connect the Gateway to any standard LoRaWAN® Server. The device is capable of tackling applications related to Smart Grids, Intelligent Farms and other IoT Enterprise applications.
