Wireless Systems

Answer: Yes and No. In the wireless world, line of sight is defined as the transmitter being able to ‘see’ the receiver.  A better way to think about this is that the transmitters have better vision than we do and the transmitters are able to ‘see’ through some objects.  There are many variables that will affect your wireless system such as operating frequency, operating power (watts), physical obstacles, environmental conditions, and more.  Therefore, ‘line of sight’ is just one of many important variables when you are designing your system.
