AUDIOCODECS AEQ PHOENIX APPLICATION NOTE 4 B Connecting two Phoenix Audiocodecs through a point to point IP radio link operating in the 5 GHz band Configuration of the units via remote control software 1 DESCRIPTION OF THE SCENARIO Recently several manufacturers have started to offer digital radio links with IP connectivity based on IEEE 802 11a using extremely directive antennas that operate in a free RF band These links can be used to transport data between several locations to join venues of a same organization or grant Internet access to places where ADSL is not available The main features of these products are long range low power consumption and nice cost effectiveness We can use them for bidirectional audio transport between two radio broadcast production centers in a same town or setting up a link between radio studio and transmitter STL or between a remote location where some event is being held and the radio studio We have evaluated two solutions with different cost and performance ranges Ubiquity presents a wide range of systems with different performance levels and a very adjusted price that operate under the same setup operation software platform called AirOS v5 that is incorporated in the equipment as an embedded Web server The IP Nanobridge M 5G22 system has been tested but the procedure followed is very similar to tens of Ubiquity products that are configured the same way On the other hand we have also
