LoRa (short for long range) is a spread spectrum modulation technique derived from chirp spread spectrum (CSS) technology. Semtech's LoRa is a long range, low power wireless platform that has become the de facto wireless platform of Internet of Things (IoT). What is LoRa used for? LoRaWAN...
DSSS is a spread spectrum modulation technique used for digital signal transmission over airwaves. It was originally developed for military use, and employed difficult-to-detect wideband signals to resist jamming attempts. It is also being developed for commercial purposes in local and wireless networks...
Because the channel width is small, it allows the NB-IoT signal to bury itself inside a larger LTE channel, replace a GSM channel or exist in the guard channels of regular LTE signals.LoRaWAN is a spread spectrum modulation technique designed to facilitate communication between low-power ...
This technology is employed to transfer data between devices over radio waves. It relies on a wideband modulation technique, creating linear frequency modulated signals referred to as chirps. The chirps operate in a 2.45 GHz ISM band. They make it possible to distribute radio signals across a bro...
In case the carrier frequency’s rate of change is higher when compared to the symbol rate, the technique is often known as a fast frequency hopping system. If the rate of change is less than or equal to the symbol rate, it is referred to as slow frequency hopping system. A fast ...
LoRa stands for long range and uses the spread spectrum radio modulation technique. LoRa modulation first started in 2010 by the French company Cycleo for encoding data in radio waves and later bought by Semtech. What Is LoRa? LoRa Explained Originally developed for adding wireless communication ...
LoRa (Long Range) is an emerging wireless communication technology developed by US Semtech, an ultra-long-distance wireless transmission scheme based on spread spectrum technology. Lora changes the previous way of thinking about the compromise between tr
LoRa stands for Long Range and refers to a spread spectrum modulation technique that enables long-range communications over unlicensed spectrum. In this article, we discuss what LoRa is, the radio frequencies used, types of LoRa antennas, key antenna characteristics, matching considerations, and ...
was primarily developed for mobile communication, its spread spectrum technique and multiple access capabilities could potentially be adapted for other wireless communication applications. however, its use outside of mobile networks is limited, as newer technologies like wifi and bluetooth® are better ...
Direct-sequence spread spectrum (DSSS) DSSS is a related technique to FHSS. It also spreads a transmitted signal across a wide channel, but it does so all at once instead of in discrete bursts separated by hops. It can achieve higher throughput, but DSSS systems are more susceptible to inte...
