Proxim Tsunami QuickBridge II GPS Antenna Kit (Mnf.Part # 65157)
Proxim Tsunami QBII must use GPS synchronisation if more than
one device located at the same place. Master radios must be on the same site.
Tsunami QuickBridge II radios operate using Time Division
Duplexing (TDD), letting radios operate in a single RF channel shared between
transmit and receive. If several QuickBridge II radio links must operate in
close proximity (as would be the case if radios are co-located on a rooftop or
on adjacent buildings), their transmitters must be time-synchronized to prevent
interfering with receive signals of adjacent radios.
GPS synchronization minimizes interference between co-located QuickBridge II
radios and allows radios to synchronized even if they are not physically
In general, QuickBridge II radios are considered co-located if
you can see another radio from a potential installation location (within line-of-sight)
or if there is another radio installed within 300 feet. (Exact rules are
difficult to make due to local environmental variables.) Synchronization is
accomplished using a satellite-derived 1 Hz timing signal from an external GPS
receiver connected to each of the co-located QuickBridge II radios. Because far-end
QuickBridge II radios are slaved to the co-located Master radios, the far-end
radios do not require GPS receivers.
Note: The maximum cable length for attaching the GPS antenna is 7meters (approximately
