Abstract :
Tower-mounted LNA is known for improving the cell site performance (reverse link range extension) in a rural environment. A series of tests were performed at a CDMA test cell site to study the benefit of tower-mounted LNA, the impact of the loss of cables, and its applicability to all different environments. The slope and intercept of the drive route is measured to characterize the testing environment. The performance of diversity is also studied. A spreadsheet for (propagation parameters) noise figure model was also developed and compared with the test results
