Smart antennas have been tested in a variety of field locations with promising results. The new antenna has demonstrated a considerable advantage over various indoor antennas with no amplification and the set-top UHF loop/VHF rod antenna combination with built-in amplification. In a few locations, Smart Antennas may be unable to automatically optimize the signal. A simple antenna works for a simple RF environment. Smart antenna solutions are required as the number of users, interference and propagation complexity grows. Their smartness resides in their digital signal processing facilities. Like most modern advances in electronics today, the digital format for manipulating the RF data offers numerous advantages in terms of accuracy and flexibility of operation.
