at the hop in decibels (dB). This value is the minimum of the
signal strengths measured at the device and its proxy.
Signal Margin
Direct Communication Devices: The amount in decibels (dB)
that the signal margin exceeds the recommended amount
calculated by the SmartServer for reliable communications at
the device.
Proxies and Target Devices: The amount in decibels (dB)
that the signal margin exceeds the recommended amount
calculated by the SmartServer for reliable communications at
the hop.
