LoRa Wireless Network Technology
LoRa is a proprietary chirp spread spectrum radio modulation technique for use in a low-power wide-area network (LPWAN). It is a WAN specification designed to enable long-range, low-bit-rate communication among “things” (i.e., connected objects) such as battery-powered sensors, and it uses license-free sub-GHz radio-frequency bands such as 196, 433, and 868 Mhz in Europe and 915 MHz in North America. An LPWAN may be used to create a private wireless sensor network or a third-party service or infrastructure.
The Wzzard LRPv Node and SmartSwarm 243 Gateway support wireless long-range network communication without the need to pay telecommunication fees, thus reducing network operating costs considerably. This is particularly pertinent for reducing the cost of flood monitoring because most water bodies are large and do not have control centers located near them. Furthermore, traditional wireless solutions (e.g., access points) have a limited data transmission range and thus force users to adopt an intensive approach to node deployment. Even though cellular routers are unaffected by such problems, they require paying telecommunication fees.
