The effects of UWB interference on GSM systems

The effects of UWB interference on GSM 900 and GSM 1800 systems are considered for current FCC regulations as well as proposed ETSI emission limits for the criteria of either a 1 dB loss in the SINR or a loss leading to the minimum required SINR at the cell edge. UWB densities are computed for different GSM reuse factors and the results show that no harmful interference is to be expected for GSM 900 systems. In the case of GSM 1800 systems, the proposed ETSI emission limits are found to be offering sufficient protection whereas the current FCC regulations would result in significant interference.
