 The impact of the RF fields from the wireless device transmitter
on host/terminal operation
The latter consideration is not a significant problem. If RFI is assessed
properly, it is usually corrected with little effort and cost.
Because of the need for system coverage, the host/terminal EMI
interaction with the radio receiver can be a significant and often elusive
problem to characterize and correct. Most host/terminal devices are
very fast and include numerous high frequency radiators. These can
interfere with the radio reception of the wireless modem.
The theoretical levels at which the receiver might be impacted are
derived from system coverage requirements and the sensitivity of the
radio. These goals are not set arbitrarily to improve product
performance, but to maintain the RF performance the networks demand
and the radios are designed to deliver.
Since each product is unique. The level of noise is very difficult to
predict, as is the amount of effort needed to control it. Measuring the
product in an early engineering phase is key to managing the situation.
