Nextiva S4200 Series User Guide
The boot sequence of slave devices is:
1. The device goes through the standard startup procedure.
2. The device roams through the channels in the available frequency bands to locate its
master; it does not transmit any data.
3. When the master is located, the slave runs normally on the selected frequency channel.
4. If the slave detects a radar on the channel during normal operation, it informs the
master then stops operation. Upon reception of this message, the master starts its
radar detection process.
Radar detection on slave devices can be disabled; for more information, see page 29.
Colocated Cells
You can operate many wireless cells in the same location, provided you follow guidelines
relative to frequency channel, wireless passkey, and distance.
The wireless passkeys of colocated cells must be different from one another, regardless of
their frequency channels.
Distance Limitations
The distance limitations between devices in colocated cells are:
„
The minimum distance between two devices is 3 feet (1 meter), regardless of the band
or channel used.
„
To avoid material damages, you must never power any two devices while their
antennas are facing one another with a distance of less than 10 feet (3 meters).
„
To reduce radio interference, separate as much as possible devices sharing the same
pole or installed on the same roof, even if they do not use adjacent channels.
„
If using adjacent channels, see page 120 for the recommendations on the minimum
distances to respect.
