3. In each cell, install the S4200 devices such that each one has a clear RF line of sight
with its associated S4300 access point.
An illustration of this application is on page 27, where the three cells are in the same
location.
5 GHz Band in Europe
The variety of supported colocalization setups is limited in Europe because of:
DFS regulations, mainly with the automatic channel selection that forces the master
devices to see each other.
False radar detection that can happen when using adjacent channels. By default, only
half the frequency channels are available, therefore ensuring that no adjacent channels
are used; however, you can make all channels available (for more information, see
page 29).
It is suggested to limit the number of colocated cells to six in the 5.40–5.725 GHz band. By
respecting the following steps, you can assume that the cells will not share the same
frequency channel, making the complete bandwidth available for each one:
1. Assign a different wireless passkey to each cell.
2. Ensure that all masters “see” one another. For more information, refer to the “RF
Contact between Masters” appendix in the Nextiva S4300 Series User Guide.
This step is mandatory if automatic frequency channel selection is selected, and
strongly suggested for manual selection.
3. Position the devices so that there is at least 3 feet (1 meter) between each antenna.
4. If automatic channel selection is used, set a different starting order in each master
device: 1 for the first device, 2 for the device next to it, 3 for the third one, and so on.
Installing more than six cells in the 5.40–5.725 GHz band requires the use of adjacent
channels. This situation demands greater distances between the antennas to reduce
potential radio interference and false radar detection. Therefore, you should contact the
customer service team for assistance.
