What is a good RSSI for LoRa?
Typical LoRa RSSI values are: RSSI minimum = -120 dBm. If RSSI=-30dBm: signal is strong. If RSSI=-120dBm: signal is weak.
What is LoRa bandwidth?
A proprietary spread-spectrum modulation technique derived from existing Chirp Spread Spectrum (CSS) technology, LoRa offers a trade-off between sensitivity and data rate, while operating in a fixed-bandwidth channel of either 125 KHz or 500 KHz (for uplink channels), and 500 KHz (for downlink channels).
Can I use GSM antenna for LoRa?
By wirelessly enabling devices and terminals to operate using LoRa technology, applications can be developed for control and monitoring without the need to use mobile cellular networks such as GSM, 3G or LTE. …
How do I increase my LoRa range?
As a general rule, elevating LoRa devices by placing them on rooftops or higher altitudes will help to improve their transmission range! Other factors, such as – you guessed it – antenna properties can also significantly impact transmission range!
Do you need license for LoRa?
LoRa uses license-free sub-gigahertz radio frequency (RF) bands, including 433 MHz, 868 MHz (Europe), 915 MHz (Australia and North America), and 923 MHz (Asia). LoRa enables long-range transmissions with low power consumption.
How fast can LoRa transmit?
300 bps to 37.5 kbps
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).
What antenna does LoRa use?
If you’re looking for a LoRa antenna to enhance your LoRa communication systems, you should definitely consider Seeed’s LoRa Fiberglass Antennas, which have been specifically designed for use with LoRa radio bandwidths (860MHz – 930MHz).
Is LoRa an FHSS?
LR-FHSS is a fast FHSS modulation used for uplink only; downlink communication is achieved with current LoRa, since the same radios can switch between modulations.
