is all wireless communications a line of sight communication?
is there any exception?
does it apply for both analog and digital.
thanks

Hi,
Not all wireless communication systems are using line of sight configuration,
For point-to-point communications (esp. microwave comm.) use line of sight, Broadcasting uses isotropic radio propagation (also HFSS/DFSS)
I hope this info made your mind clear
regards

most wireless comm. network are able to work both LOS and NLOS schems. for example in mobile communications, when you are in a building, you have a NLOS communication with the BS.
both digital and analog telecommunications can work in these two schemes because this problem is related to the transmission signal models in different area
