1General Description
1.1 Product Description
RAK7258 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 communication. Gateway can connect the NS (network server) via standard
Ethernet, and support network and firewall functions. RAK7258 also supports 2.4G WiFi
and LTE (optional) uplink communication connections.
RAK7258 built-in OpenWRT operating system, users can flexibly configure network
parameters and LoRaWAN protocol parameters through the Web management platform.
RAK7258 supports MQTT Bridge function, can use the MQTT integrated to third-party
platforms.
RAK7258 can connect the standard NS (network server) and the local NS. At the same
time, RAK7258 also supports the built-in NS. 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. RAK7258 integrates the
RAK2247 LoRa concentrator module, which supports eight uplink channels and one
downlink transmission channel. For the heating problem of SX1301/8 centralized
operation, RAK2247 uses the graphene, silicone grease to optimize the heat dissipation
performance of chips and modules and ensure the stability of transmission.
1.2 Product Features
