Abstract :
This paper presents a unique concept of `Spotlight coverage´ for outdoor multi-antenna (or DAS) cellular systems. This concept helps in achieving high Signal-to-Interference Ratio (SIR) throughout the cell coverage area by effectively controlling the leakage into the neighboring cells. Interference and coverage analysis of traditional wall mounted and street lamp mounted (providing spotlight coverage) multi-antenna cell have been presented and compared. Results show considerable improvement in the SIR for street lamp mounted multi-antenna cells.
