• The level of interference at the active channel
• The terrain of the covered area.
In rural areas where the WBSn base station is installed relatively high (10m above other buildings), and
there are no interferences, the range can be up to 20 km.
Q: How can I determine the best channel to work in?
A: Use the ACS feature
to search for a clean frequency
Q: Does WBSn base station support roaming?
A: The Wavion Base Station supports the part of 802.11f, which supports handover between access
points that reside on the same Layer-2 domain.
The WBSn handover implementation sends a Layer-2 packet with the source address of a newly
associated client. This packet is sent as broadcast message allowing all Layer-2 devices in the network to
update their MAC address caches.
This solution will work if the backhaul network is configured as a flat Layer-2 network. When the network
is composed by multiple IP subnets, another device (e.g. a session controller) should handle roaming
across subnets.
Q: Is it possible to co-locate a number of WBSn base stations??
A: Yes, three WBSn units can be co-located. A minimum of 8 meters separation is recommended when all
units are on the same RF channel. However, the units will suffer from throughput performance due to
mutual interference.
A one-meter separation is possible when units are operating on different RF channels 1,6,11. It is highly
recommended to have as much distance as possible between units and to use RF channels 1,6,11 in
order to reduce throughput degradation.
We recommend that you avoid installing the units at the same height, by leaving a vertical distance of at
least 1 meter between them.
Q: What is the minimum distance required between two WBSn units?
A: Two meters is the minimal recommended separation.
Q: What are the tower installation requirements?
A: WBSn must be installed at least 1 meter away from any adjacent metal object.
Q: What are the pole installation requirements?
A: WBSn must be installed with antenna higher than the end of the pole.
Q: What is the nominal noise level for optimal performance of WBSn?
A: Nominal noise level without interference is -97dBm. Utilize the ACS feature to search for a clean
frequency with a noise level between -85dBm to -97dBm. Higher values indicate higher noise levels due
to interference.
Q: What is the maximum Ethernet cable length that can be used with a POE?
A: The maximum cable length is 100 meters.
Q: Where is the WBSn reset button?
A: The reset pin hole button is located below the USB port. To reset the system to factory default
parameters press the button until the STATUS LED is on steady with a red light.
