LOS , Near LOS and Non LOS
LOS : LOS means line of
sight , line of sight in radio communication refers to the condition where
minimum 60% of first Fresnel zone (refer
to Fresnel zone in blog ) is clear, In modern radio communication systems
operating above the 2.4 Ghz frequency requires clear LOS.
Near LOS : Near Los means near
line of sight , it refers to the condition in radio communication where a
straight line from Site A to Site B is unobstructed but 60% of first Fresnel
zone is not clear .
Wimax
technology (refer Wimax Technology in
blog) if developed to combat the interference occurred due to the near LOS
reflection.
Non LOS : Non LOS means non
line of sight , it refers to the condition where Fresnel zone is completely
obstructed . this condition is avoided in modern microwave radio
communications.
Non LOS communication can take place in low frequencies, nowadays very less in commercial
use because of throughput requirement .
