CreataLink2 XT Hardware Integrator’s Guide Appendix B
Summary
Summary
Consider these two basic interactions when you use a wireless device and computer
as a system:
• The impact of the computer EMI on the system performance
• The impact the of the RF fields from the wireless device transmitter on the
operation of the computer
The impact the RF fields from the wireless device transmitter is not a significant
problem. It can be corrected with minimal effort and cost.
Because of the need for system coverage, the host EMI interaction with the radio
receiver is difficult to identify and correct. Computer speed includes high frequency
radiators that interfere with the radio reception of the wireless data transceiver.
This manual identifies the theoretical noise levels that affect the receiver. The goals
are derived from system coverage requirements and the sensitivity of the radio.
They are not arbitrarily decided to improve product performance, but to maintain
the performance of the RF networks and the radios. The target level and methods
to achieve these goals are the choice of the product integrator. The preferred
methods mentioned are the result of experiments and past product experiences.
Each product is unique; measure the product in an early engineering phase.
