Everybody knows that the 950 MHz STL band is terribly crowded in all but the smallest markets.
Hardly a month goes by without a story about somebody knocked off the air by another station turning on an STL. Or where STL bandwidth was reduced by the frequency coordinator. Or where commercial and residential construction has obliterated transmission paths.
Ethernet to the rescue.
You may have heard about the newest breed of STL: Ethernet radios. These data transmission devices connect directly to Ethernet networks to enable long-distance data transmission. And since Axia IP-Audio networks use Ethernet for audio transmission, they're natural partners.
Axia audio nodes combined with Ethernet radios make it possible to send carry multiple channels of bi-directional analog or AES audio (as well as GPIO) over wireless data links that operate outside that crowded 950 Mhz band. And these audio channels are uncompressed... so there are no coding artifacts to worry about.
And since the new station-to-transmitter link is Ethernet, it carries data as well as audio. Great for audio processors with Ethernet remote control, transmitter control commands, security camera feeds, audio monitor backhauls, or whatever. (We're sure you can think of lots more uses.)
Best of all, thanks to the natural scalability of Axia networks, the link can be easily reconfigured to add and subtract audio channels, which makes it perfect for HD Radio applications.
The simplified diagram above shows what an Axia STL system typically looks like. Program audio goes into an Axia xNode, then to the Ethernet radio, and out the other end. As long as there is adequate bandwidth on your Ethernet radio, GPIO (contact closures) and backhaul is possible as well.
