LoRa is a wireless standard for low-power local area networks created by Semtech. Low power consumption is generally difficult to cover long distances. Generally, long-distance power consumption is high. It seems difficult to run if the horse does not eat grass. The name of LoRa is Long Range Radio. Its biggest feature is that it spreads farther than other wireless methods under the same power consumption conditions. It realizes the low power consumption and long-distance unity. It consumes 3-5 times longer distance than traditional wireless radio frequency communication.
Transmission distance: up to 2-5 Km in towns and 15 Km in suburbs.
Working frequency: ISM frequency band includes 433, 868, 915 MH, etc.
Standard: IEEE 802.15.4g.
Modulation method: Based on spread spectrum technology, a variant of linear modulation spread spectrum (CSS), with forward error correction (FEC) capability, semtech's proprietary patented technology.
Capacity: A LoRa gateway can connect thousands of LoRa nodes.
Battery life: up to 10 years.
Security: AES128 encryption.
Transmission rate: Hundreds to tens of Kbps, the lower the rate, the longer the transmission distance. This is much like a person picking things. If they pick more, they will not go too far.
