Sector Transmit Power Pooling on Real CDMA Networks


This paper uses logfile data from commercial code division multiple access networks to quantify the base station power amplifier (PA) size reduction achieved with sector transmit power pooling. Sector transmit power pooling in a base station involves sharing the transmit power load of several sectors across the same bank of amplifiers. This transmit power trunking results in a reduction in required PA size. The logfile analysis used to estimate this reduction is augmented with simulated shortterm power variations. A new constrained Poisson call arrival model is used to ensure that the simulated power variations accurately reflect actual network operating conditions. A Gamma random variable approximation is also used to improve simulation efficiency. The results of this analysis indicate that sector power pooling can significantly reduce required PA size for realistic network operating conditions.
