LoRaWAN communication system. The data transfer rate varies from 300 bps to 37.5 kbps , depending on the spreading factor and the bandwidth of the communication channel. A LoRa Gateway has the ability to simultaneously receive and broadcast messages with different SF (spreading factors).
Read moreCan LoRaWAN be hacked?
Long Range Wide Area Network (LoRaWAN) devices have been hacking targets for quite some time . We dive into attacks that malicious actors can use against vulnerable LoRaWAN devices, and review the state of LoRaWAN security.
Read moreWhich one of the following is a disadvantage of LoRa?
The main disadvantage of LoRa however is exactly what enables its strengths, namely the low bandwidth . Furthermore, the protocol doesn’t allow continuous sending, due to rules on the frequency band it utilises. Because of this, LoRa is only suited for short and periodical communications.
Read moreHow reliable is LoRaWAN?
LoRaWAN is by design very secure —authentication and encryption are, in fact, mandatory—but networks and devices can be compromised if security keys are not kept safe, not randomized across devices or if cryptographic numbers used once (nonces) are reused, as is shown by numerous blog posts.

LoRaWAN communication system. The data transfer rate varies from 300 bps to 37.5 kbps , depending on the spreading factor and the bandwidth of the communication channel. A LoRa Gateway has the ability to simultaneously receive and broadcast messages with different SF (spreading factors).
Read moreWhat are LoRaWAN channels?
LoRaWAN defines 64, 125 kHz channels from 902.3 to 914.9 MHz increments . There are an additional eight 500 KHz uplink channels in 1.6 MHz increments from 903 MHz to 914 MHz. The eight downlink channels are 500 kHz wide starting from 923.3 MHz to 927.5 MHz. The maximum output power for North America is +30 dBM.
Read moreWhat frequencies does LoRaWAN use?
LoRa (Long-Range) is digital wireless data communication IoT technology. LoRa transmits over license-free megahertz radio frequency bands: 169 MHz, 433 MHz (Asia), 868 MHz (Europe) and 915 MHz (North America) .
