percentage of lost links for each radio is also presented. It is the total
of lost links divided by the number of links established over the
selected time interval. Radios are listed in order of the percentage of
lost links, with the radio having the highest percentage of lost links
placed first.
The number of links established over the selected time interval for
each radio is also presented in the data window. Sample size is an
important consideration when judging the validity of the statistics.
The larger the sample size, the more meaningful the data.
The two sources of lost links are as follows:
Portable Reestablish
A portable may attempt to reestablish a link on a different channel
when it identifies interference or signal loss on the current channel.
The portable sends a reestablish message to the radio that results in
the loss of the original link. If the attempt is successful a short voice
break is experienced before a link is reestablished with the portable
on a new channel.
Radio Lost Links
Links may also be lost when a radio cannot receive the portable's
signal or when it cannot decipher the portable's signal. The portable
attempts to reestablish the link after this radio link is lost. If the
attempt is successful a short voice break is experienced before a link
is reestablished on a new channel.
The dialogue window gives the number of system links established
and the number of radios with lost link levels greater than 5% over
the selected time interval.
