An unobstructed path from a transmitting device to the receiver. Users are aware of line of sight when they aim their infrared (IR) remote control directly at the TV. Microwave transmissions ...

primarily because of the availability of high-sensitivity receivers and the ability to provide either broad coverage at low frequencies or line-of-sight propagation at high frequencies.

This multipath propagation disrupts signal integrity, leading to loss of connectivity. Large, power intensive setup and ...
