Particular attention is required for product installation. In the case where
several links must works in the same area (independently of the channel
positions), the minimum distance between 2 products belonging to different
radio links is 3 meters. Even with this precaution (depending of the product
environment), channel rejection could be reduced.
RSSI reading
The RSSI (Received Strength Signal Indicator) gives an indication for the
received power level.
It could be accessed with AT commands (ATS230?<cr> command).

The RSSI level is only an indication. Use this level with care due to
the dispersion between components.
The operating temperature could also have an impact on these
dispersions.
The RSSI level could also indicate the potential presence of any
jammer in the used channel.
The RSSI is a necessary but not sufficient condition to
obtain a correct reception.
