Boomer-III User Manual & Integrator’s Guide______________________________ APPENDIX F – Guide to DesenseBM310012WT04 139 Copyright Wavenet Technology © October 2003 The impact of the RF fields from the wireless device transmitteron host/terminal operationThe latter consideration is not a significant problem. If RFI is assessedproperly, it is usually corrected with little effort and cost.Because of the need for system coverage, the host/terminal EMIinteraction with the radio receiver can be a significant and often elusiveproblem to characterize and correct. Most host/terminal devices arevery fast and include numerous high frequency radiators. These caninterfere with the radio reception of the wireless modem.The theoretical levels at which the receiver might be impacted arederived from system coverage requirements and the sensitivity of theradio. These goals are not set arbitrarily to improve productperformance, but to maintain the RF performance the networks demandand the radios are designed to deliver.Since each product is unique. The level of noise is very difficult topredict, as is the amount of effort needed to control it. Measuring theproduct in an early engineering phase is key to managing the situation.
