Overview
This document helps customers quickly understand the hardware interface, RF, software and electrical specifications of RAK7268C.
Description
RAK7268C is an indoor gateway based on low power LoRaWAN protocol. It supports PoE power supply and can connect the standard LoRaWAN terminals and carry out bidirectional.
Gateway can connect the NS (network server) via standard Ethernet, and support network and firewall functions. RAK7268C also supports 2.4G WiFi and BLE .support LTE (optional) uplink communication connections.
RAK7268C built-in OpenWRT operating system, users can flexibly configure network parameters and LoRaWAN protocol parameters through the Web management platform. RAK7268C supports MQTT Bridge function, can use the MQTT integrated to third-party platforms.
RAK7268C can connect the standard NS (network server) and the local NS. And it also supports the built-in NS (By default, a license that supports 128 terminals and 5 external gateways is embedded. If your demand exceeds the above limit, please contact the sales department for a new license). It does not need users to deploy NS in the cloud and locally. It is especially suitable for small and medium-sized scenarios in industry applications, saves the cost for server and R&D investment, and has the advantages of high execution efficiency and shorter delay. According to customer’s choice,RAK7268C integrates the RAK2287 or RAK2247 LoRa concentrator module, The RAK2287 LoRa module supports eight uplink channels and one downlink transmission channel.
For the heating problem of SX1302 centralized operation,RAK2287 uses the graphene, silicone grease to optimize the heat dissipation performance of chips and modules and ensure the stability of transmission. The RAK2247 is a LoRa concentrator module with the mini PCIe form factor based on SX1301, which enables an easy integration into an existing routers and others network equipment with LoRa Gateway capabilities.
