A Multiple-Antenna System for ISM-Band Transmission
We present a multiple antenna system for industrial, scientific, and medical (ISM)-band transmission (MASI). The hardware demonstrator was developed and realized at our institute. It enables multiple-input multiple-output (MIMO)-communication applications and is capable of transmiting arbitrary signals using 8 transmit and 8 receive antennas in parallel. It operates in the 2.4GHz ISM-band. The ...
متن کاملA European ISM Band Power Amplifier Module
In this paper we present a power amplifier module suitable for the 433MHz European ISM band frequency. The PA module provides a maximum 30dBm output level at 433MHz. The included power control circuit provides 30dB of dynamic range control. The overall module was designed on a single test board with a 4.8V supply voltage. The maximum output power deviation is less than 1dB over the complete con...
متن کاملiSCISM: Interference Sensing and Coexistence in the ISM Band
1. Introduction A multitude of commercial devices transmit in the unlicensed 2.4 GHz ISM band, and these devices are likely to interfere with each other. These effects are compounded in highly populated metropolitan areas with large numbers of microwave ovens, Bluetooth devices, cord-less phones, wireless game controllers, and other devices which occupy the ISM band. This contributes to an ever...
متن کامل1 Coexistence in the 2 . 4 GHz ISM Band
The 2.4 GHz ISM band provides an attractive medium for developing tethered free applications based on current and proposed wireless standards. Since the ISM band is a shared spectrum allowing unlicensed operation of wireless services, coexistence between the wireless services needs to be considered to ensure performance requirements are maintained. A general method for evaluating coexistence is...
متن کاملCir Measurement System for Characterisation of Wideband Communication Channels in the 2.4 Ghz Ism Band
A 2.45 GHz pulse compression, channel impulse response (CIR) system is described. The motivation for its development and results verifying its performance are given. The system is shown to be an effective test and measurement tool for analysis of 2.4 GHz ISM band channels particularly for spread spectrum communication system deployment. The required signal processing is described and, because o...
