Features of LoRa Chips

Those who do the Internet of Things are no strangers to FSK and LoRa. These two are Internet of Things technologies that use a relatively wide range of price comparisons. LoRa is the abbreviation of the two words Long Range, which means "long-distance" transmission.The principle of LoRa is similar to that of FSK, but it is an innovative chirp expansion technology

In 2012, Semtech, the world's leading supplier of semiconductor products, withdrew from this technology, and in a few yearsUnder the continuous promotion of the continuous integration, upgrade and optimization of the chip, some beneficial ecosystems and solutions have been developed. These solutions include gateways and various terminals, which have successfully promoted LoRa to all parts of the world

What are the characteristics of LoRa chips?

1. Longer communication distance

Under normal circumstances, the longest can reach 10km

2. StrongerAnti-interference ability

Even in towns, normal communication can be carried out without worrying about being interfered by other noises

3. Low energy consumption

Generally, the sleep current of LoRa chips is less than1uA, the transmission current during operation is also very small

4. Larger network capacity

LoRa communicates in the same frequency band, similar to code division multiplexing, and different spreading factors in the same frequency band will not interfere with each otherThis is due to LoRa's comprehensive establishment of network capacity determinants such as node packet frequency, data packet length, signal quality and node rate, number of available channels, base station/gateway density, signaling overhead and number of retransmissions.XOR and optimization.It is based on these characteristics that LoRa can easily complete the on-demand arrangement
