Sports Arena
In this example, we have a 2000 spectator sports arena with a metallic roof that had an indoor
signal strength too low to provide fair service in most parts of the arena. The nearest base
station was 8 kilometers away and was equipped with only one carrier. A donor antenna
directed towards the BTS was mounted on a mast outside the building and a repeater was
installed inside the building with the service antenna on the ceiling as illustrated in Figure 1-14.
The antenna isolation was measured to over 85dB.
The signal strength was fair for service in the entire arena.
