This paper reports the measurement results of the operating current and the throughput for Bluetooth wireless communication modules. Recently, various wireless communication equipments that operate at 2.4 ㎓ frequency are used. Especially, Bluetooth, which operates at 2.4 ㎓ frequency, is installed for mobile devices such as mobile phones and music players, and can be expected to be used widely in the future. To use Bluetooth wireless communications capability on the equipment without those capability, ZEAL series which is general-purpose Bluetooth wireless communication modules released by ADC Technology. In ZEAL, there are two types of modules with the differences of Bluetooth classes. One is Bluetooth class 1 ZEAL-S01 that allows communicating over the 100m range. The other is Bluetooth class 2 ZEAL-C01 that allows communicating over the 10m range. In addition, there are three power levels of low-power level, standard level, and hi-speed level in ZEAL-C01 with firmware version 2.0.2.1. Then, to investigate power consumption and the throughput in each power levels in ZEAL-C01, those operation current and the throughput is measured for ten of baud rates that are from 2,400 bps to 921,600 bps. As a result, the supply current of all modules doesn’t depend on the baud rate. As a result, we have obtained the result that range of throughput that can be used to communicate actually in ZEAL-C01 at each levels.
