Network Entry SNR (dB) "low" -this option sets the minimal signal level for the neighbor.
Signal level is measured in dB above the noise threshold for the
current bitrate. If the level gets lower than specified value the
connection with a neighbor will be lost.
"high" -this option sets the minimal SNR for a new neighbor. Signal
level is measured in dB above the noise threshold for the current
bitrate. If neighbor’s signal level is equal or higher than a specified
value the node will consider this neighbor to be a candidate
Network Entry EVM (-dB) "high" - minimum EVM value required to establish a radio link
between two devices. Value by defaut - 8.
"low" - minimum EVM value at which the radio link between devices
will not be broken. Value by default -0.
RX Attenuation The noise level measured by the radio module is calculated as the
minimum received signal level (RSSI) in a certain period
The "RX Attenuation" parameter allows manually raise noise
threshold on several dB. In this case the radio module won't react to
signals below the established threshold. In certain cases it gives the
ability to be protected from the low signals interferences which
disrupt the radio module as a result of capture effect. This effect is
expressed in the fact that the radio module having captured the low
signal from the foreign source, tries to strengthen it and to accept
completely ignoring a strong signal from the client which has
appeared later
This parameter allows to protect the receiver from the powerful signal
source overload
