The ISM band is an extremely over utilized communications medium. Wireless LAN technology, Bluetooth, and landline wireless devices all make use of the ISM band. The support vector machine is proposed as a tool for predicting channel availability and thus using the band more efficiently. Data processing, feature extraction, and results are presented. Suggestions for future work in this area are...

A probe feed, slotted hexagonal patch antenna has been proposed. Bandwidth enhancement has been improved by suitably cutting slots into hexagonal patch. Proposed antenna is suitable for various telecoms, LAN, WiFi applications in ISM-band. It is demonstrated that the proposed antenna exhibits resonance in ISM-Band and a peak gain of 6dBi.The antenna structure is described and simulated results ...

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...

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...

A tri-band miniaturized Planar Inverted F Antenna (PIFA) design for bio-telemetry communications is investigated in this work. This smaller antenna effectively covers the three bands namely the Medical Implant Communications Service (MICS) band, the Industrial, Scientific, and Medical (ISM) band and a third band which is devoted to make the implanted device to work as and when required. The ope...

In this paper, radiation from microwave ovens is measured using PRISM, a custom-built device designed to measure transmissions in the ISM band. The measured signals, treated as a rising noise floor, are then applied to a semianalytic simulation to determine the probability of frame error rate (FER) per channel for six Bluetooth packet types [1]. Keywords—Bluetooth; ISM band; Microwave ovens; Fr...
