EDGE Network / Jan 2016

G E N E R A L   I N F O R M A T I O N

The EDGE alleviates this random latency problem by adding a buffering mechanism 

 between the radio and the network. The EDGE can be located at either end of the link, 

but the way it operates with WheatNet‑IP  depends which end it is located on. For both 

cases, the internal hardware of EDGE remains mostly the same. Small .25 msec packets are 

­ingested,­buffered­and­repackaged­as­5­msec­packets.­There­are­4­instances­of­this­RX-TX­

mechanism which we have denoted as BIG for signal name defaults.

EDGE Installation Options

The EDGE may be installed at either the Studio or Transmitter sides of the IP‑STL link. 

Where you decide to install it depends on a few factors:

•­

IP Radio quality

•­

BLADE infrastructure

•­

Cost.

EDGE Installed on the Studio Side

For a “Studio‑Edge” IP‑STL application, the EDGE connects to the WheatNet‑IP Ethernet 

network located at the studio end of link and a BLADE is then located at the transmitter 

(TX)­end.­The­TX­side­BLADE­connects­to­another­Ethernet­switch­along­with­the­IP­Radio.

In this case, PGM audio from a control room needs to get through an IP radio to the 

 transmitter site. In Navigator, the desired PGM mix Source is routed to one of the four 

EDGE Buffers. EDGE Buffer inputs automatically appear as Destinations in the Naviga‑

tor­matrix­when­the­EDGE­is­first­configured.­Likewise,­the­EDGE’s­post-delay,­Buffered­

outputs automatically appear as Sources in the Navigator matrix.
