Overview
1.1
Introduction
RAK
2247
is a LoRa concentrator module with mini-PCIe form factor based on SX1301.
This enables easy integration to existing routers and other network equipment with
LoRa Gateway capabilities, and can be used in any embedded platform offering mini-
PCIe slot with SPI or USB connection.
This module is a complete and cost efficient LoRa gateway solution offering up to 10
programmable parallel demodulation paths. It targets smart metering fixed networks
and Internet-of-Things (IoT) applications, covering up to 500 nodes per square
kilometer in an environment with moderate interference.
