Mean Effective Gain for Data Mode Operation of Mobile Handsets with Users

The current paper presents statistics on the meaneffective gain (MEG) for mobile handsets. The results are basedon a large measurement campaign in an urban environmentwhere the propagation channel from two different base sta-tions to seven different handsets were measured in two bands(776 MHz and 2300 MHz). The handsets were of different types(bar, clamshell, pda), all had two antennas and were used indata (browsing) mode. All handsets were measured with twelvedifferent users with both one-hand and two-hand grips. The bodyloss, the mean difference between the MEG in free space andwith a user, was found to be up to about 15 dB with typicalvalues below 6 dB. Further results are given in terms of meanvalues, standard deviations, and analyses for differences betweentop/bottom left/right mounted antennas, as well as between one-hand and two-hand grips. Finally, the body loss distributionamong the users is modeled and used for estimation of confidenceintervals.
