Anyways, it's a complete two-way communication system based on the Arduino and the most powerful and popular 433MHz SX1278 Lora Transceiver modules.7 Oct 2021
How far can LoRa transmit?
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).
What is difference between LoRa and LoRaWAN?
LoRa is the physical layer or modulation technique used for long-range, low-power communications links. LoRaWAN is a communication protocol and network architecture that sits on top of the LoRa physical layer.
What antenna does LoRa use?
915 MHz band in the US and 868 MHz in Europe. LoRa antennas, also called Low Power Wide Area Network (LPWAN) antennas, use advanced signal processing to achieve long-range communications at wavelengths smaller than 1 GHz.
Can I use GSM antenna for LoRa?
868 MHz LoRa antennas are becoming a hot topic in our markets. 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. 20 Sept 2018
Can I use WiFi antenna for LoRa?
No, antenna are tuned to a specific range of frequencies, (WiFi is 2.4Ghz or 5Ghz,LoRa is a number of frequencies 166Mhz-915Mhz) using the wrong antenna means it will not be able to pickup (or transmit) signals in the right frequency range.1 Nov 2017
How do you make a LoRa antenna?

Can LoRa work without antenna?
As a general rule, it's not recommended to run any RF transmitters (not only specific to LoRa) without an antenna attached (or with some dummy load) as the energy from the transmission is effectively reflected by the open end and can damage the equipment.13 Sept 2019
How directional are directional TV antennas?
An Omni-Directional antenna radiates and receives the RF energy equally, providing a 360 degree radiation pattern which allows connectivity in all directions. A Directional Antenna has a radius of around 45 to 90 degrees, focusing RF energy in a required direction and limiting connectivity to that particular area.17 Sept 2019
Is omnidirectional or directional antenna better?
Omnidirectional antennas receive signals equally from all directions. Directional antennas pull in signals better from one direction. In this direction, they can detect a weaker or more distant signal than an equivalent omnidirectional antenna.
