l
On the Gateway, this statistic shows a packet that is addressed to a device the Gateway believes
is on its wireless network, the Gateway has exhausted all of its packet retries, and the Gateway
never received any acknowledgements for that packet. Reasons for this include the following:
l
The destination address is not actually in the wireless network.
l
The destination could not hear the packet from the Gateway.
l
The Gateway could not hear the acknowledgement from the destination.
l
On an Endpoint, this statistic shows a packet that is being sent to the Gateway, the Endpoint has
received no acknowledgements from the Gateway, and the Endpoint has exhausted its maximum
number of attempts per the Slave Connect Odds setting.
It is still possible that any packet included in this statistic was successfully delivered, but the radio is unable
to obtain an acknowledgement that the packet succeeded.
Upstream Noise
Note: This statistic is only valid in a MultiPoint Endpoint or MultiPoint Repeater.
The level of the RF noise at the upstream transceiver listed in the Connected To field. The number is an
average of the noise levels measured at each frequency in the upstream transceiver’s frequency hop table.
Ideally, noise levels should be below –80 dBm and the difference between the average signal level and
average noise level should be 30 dBm or more.
Upstream Signal
Note: This statistic is only valid in a MultiPoint Endpoint or MultiPoint Repeater.
The level of the signal received at the upstream transceiver listed in the Connected To field, from this
transceiver. The number is an average of the received signal levels measured at each frequency in the
upstream transceiver’s frequency hop table.
Uptime
The total time the transceiver has been running since the last reboot.
Voltage
The voltage level of the power being supplied to the transceiver.
Wireless Version
The current version number of the RF module’s firmware.
