Why is LoRa long-range?
LoRa is a chirp spread spectrum modulation [18], which uses frequency chirps with a linear variation of frequency over time in order to encode information. This outperforms traditional modulation schemes, such as Frequency-Shift Keying (FSK), and makes LoRa well suited to low-power and long-range transmissions.
How far does LoRa go?
The name, LoRa, is a reference to the extremely long-range data links that this technology enables. Created by Semtech to standardize LPWANs, LoRa provides for long-range communications: up to three miles (five kilometers) in urban areas, and up to 10 miles (15 kilometers) or more in rural areas (line of sight).
How does the Lora radio work with WiFi?
It’s also a low power protocol with batteries lasting in the year range, instead of a few days with WiFi. This is made possible by only powering up the LoRa radio when packets are being sent, instead of keeping the radio always-on (like the WiFi radio on your cell phone).
What is the range of a rfm69 Lora radio?
The RFM69 radios have a range of approx. 500 meters line of sight with tuned uni-directional antennas. Depending on obstructions, frequency, antenna and power output, you will get lower ranges – especially if you are not line of sight. What ranges can I expect for RFM9X LoRa radios?
Are there any problems with the Lora network?
The Major problems being power consumption, range/coverage and bandwidth. Most communication radios like Zigbee, BLE, WiFi among others are of short range and others like, 3G and LTE, are power hungry and the span of their coverage areas cannot be guaranteed especially in developing countries.
Where can I find list of Lora frequencies?
A more detailed list of LoRa frequencies used per country can be found at: In Europe the European Telecommunications Standards Institute (ETSI) creates standards which are used by local (= country) regulatory authorities. In the US the Federal Communications Commission (FCC) creates these standards.
