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 fact
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...
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...
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...
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 ...
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...
Under the hood, Wi-Fi 7 can quadruple the performance capabilities of Wi-Fi 6, providing 4K quadrature amplitude modulation (QAM) vs the 1K of the previous network protocol. QAM is a technique that combines two amplitude modulation (AM) signals into a single channel, effectively doubling availa...
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 ...
This filtering stage before modulating the signal is also called pulse shaping as the data pulses are filtered out to produce a clean output signal with sharp rise and fall times, which helps in accurately determining the carrier frequency of the received signal. GFSK technique is useful and used...
Introduction to LoRa: What is LoRa Technology? What is LoRa? 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 ...
