Interference effects for pico-cell indoor personal communication systems

Personal communication systems (PCS) have recently undergone tremendous growth, enhancing the number of users and the risks of interference. The PCS are extensively used also inside buildings (indoors). This paper presents a thorough analysis and empirical computation of 2nd generation CT-2 digital PCS indoor interference effects, operation ranges and reception quality. The outdoor mutual interference effects analysed previously (Gavan, 1995) are significantly reduced due to shadowing and can be neglected compared to the indoor self interference effects limited mainly by noise floor. The influence of obstructions and floors on fading, shadowing and bit error rate (BER) are considered as well as the advantage of polarization diversity for the system base station antennas
