Gver-the-air evaluation and ranking of mobile phone performance

This paper presents an investigation of the radio performance of 26 mobile phones common in the Nordic countries. Antenna performance in terms of total isotropic sensitivity (TIS) and total radiated power (TRP) of different phone models was measured. The investigation includes results for talk mode using left and right hand phantoms next to head, as well as data mode using only the hand phantom. Large variations in the performance between the various phone models were found, especially in talk mode.
