Due to the sensitivity of antennas, providing the antenna with sufficient clearances reduces the possibility of electromagnetic interference from other high-frequency components, like power ICs, clock generators, and other signal busses. This post on TTN suggests that we can use LoRaWAN-capable devices to monitor a waste bins fill level and other conditions, to notify bin management services when maintenance is required. The radiation (antenna pattern) represents the way the antenna radiates in various directions at a constant distance However, did you know that there is a less spoken-about component of LR communication that can affordably yet vastly improve your existing LR systems? In general, however, we could summarise them as follows: LR uses sub-Gigahertz radio waves, so they may pass through some obstructions based on the material they are made of. Directional antennas are also widely used (Radio relays) as they have a very narrow beam width (smaller than 30 degrees Typically, surface-mounted chip antennas are best used when the PCB of the application is extremely small.
