Measurements of total isotropic sensitivity and average fading sensitivity of CDMA phones in reverberation chamber

The authors describe two ways to measure receive performance of active terminals by using a reverberation chamber, referred to as total isotropic sensitivity (TIS) and average fading sensitivity. The latter is a new method which can be measured very fast in a reverberation chamber. It is also more representative of the actual performance of a terminal in a real fading environment than the former. Based on measured results, they conclude that the average fading sensitivity is a promising alternative to TIS measurements for characterizing receive performance of mobile terminals. The reverberation chamber is well suited for both these measurements. Average fading sensitivity measurements can be done faster than TIS and give similar relative results i.e. the average fading sensitivity shows similar difference between the different phones as the TIS results, when they read the sensitivity levels at 0.5% error level.
