2.2.
Potential Interference Sources
Systems similar to the user’s system may also exist within range and may also be a source of
interference; some typical applications to consider are:
Alarm systems
o
These typically use low duty cycles and are therefore easy to avoid using
acknowledge/retransmit methods
Car alarms (internal motion sensors)
Weather stations.
2.2.1. Time critical data
If the user requires specific time critical data throughput that cannot tolerate the delays of
potentially many re-transmissions, the user is encouraged to implement an environment-aware
algorithm that periodically monitors/scans the frequency band and maintain a list of “best
available” channels.
2.3.
Approved Usage
The radio modules can be used in a variety of physical layer configurations. The following
restricts the use to maintain compliance with the above-referenced certification bodies.
The user is encouraged to use minimum power required to establish a link, thus minimizing
interference.
Changes or modifications to the module and/or operation outside the limits set forth below are
prohibited and could void the user’s authority to operate the modules.
Uses of these radio modules are limited to the specified frequency ranges and configuration
settings. Using the radio modules outside of these limitations are prohibited and could void the
user’s authority to operate the modules. The register setting files for these configurations are
provided online at

.
2.3.1. Europe
Table 3 shows the approved configurations for use in Europe.
The maximum output power is 10 mW (10 dBm) if the module operates on a 10% Duty Cycle. If
100% Duty Cycle operation is desired, then the output power should be limited to 1 mW (0 dBm)
for the signals with less than 250 kHz BW, and -13 dBm/10 kHz for the signals with greater than
250 kHz BW.
In order to comply with the output power limitations in Europe, the maximum values given in the
tables below should be observed. Table 4 is for 10% Duty Cycle operation where higher power
levels can be used. The first number in each cell indicates the power level in dBm, and the one
inside the parenthesis is the PA Table value that is written to the transceiver chip.
