Bluetooth diversity system using a two-branch switching method

The performance of space diversity technique in Bluetooth application is investigated in this paper. The proposed diversity system was implemented and tested in a typical office environment. According to the results presented here, the advantage of space diversity is found significant when two antennas are spaced by 1/3 wavelengths and a switched diversity is used as a combining method. The diversity system increased throughput 3-5% compared with single antenna case. Results show that temporary improvement can be as high as 150% due to fading.
