Shared Channel
Shared Channel is only used in Holland to accommodate government requirements. When
enabled, it imposes timing restrictions for polling. Every 2 seconds of polling is followed by
0.5 seconds of silence—no polling occurs.
Further, if another carrier is detected on the channel, the 9160 G2 will cease radio transmis-
sions on that channel until the path is clear.
22.3.3.1 Polling Protocol Parameters
Number of Poll Windows
This parameter defines the number of poll windows the 9160 G2 will use. The value as-
signed to this parameter is dependent on the number of mobile computers and the radio link
protocol used. Table 22.1 indicates how the value assigned to the Number of Poll Windows
parameter is determined.
