Signal Strength &
Signal Quality Bars
How to Increase the
Strength and Quality
of the Signal
Signal Strength and Signal Quality are dynamic bar displays that
indicate how well your PMX is receiving signals from the Base
Station.
In particular, the Signal Strength bars graphically represent the
strength of the synchronization signal your Modem is receiving
from a Base Station. The higher the pile of bars goes, the stronger
the signal is. The color of the bars also gives an indication of the
strength of the signal. Green lines indicate an excellent signal;
orange lines indicate a good signal; and red lines indicate a weak
signal.
The Signal Quality bar area graphically represents the Signal-to-
Noise Ratio (SNR) received by your Modem. Again, the quality of
the signal is represented by a group of colored bars. The higher the
pile of bars goes, the better the SNR of the signal. The color of the
bars also gives an indication of the quality of the signal. Green
lines indicate an excellent signal or an SNR greater than 21.
Orange lines indicate a good signal or an SNR greater than or equal
to 13 but less than or equal to 21. Red lines indicate a weak signal
or an SNR less than 13.
To increase the strength and quality of the signal, change the
location of the PC in which the PMX is inserted. Try moving it
closer to a window, to a higher location, away from other wireless
devices (microwave ovens, cordless phones), and away from metal
objects (shelves, file cabinets). As you reposition your PC, watch
the Signal Strength and Quality bars on the NavDiag screen. Place
your PC in the location where you receive the most green signal
strength and quality bars.
