Audio distribution to satellite Information
Radio Stations may be accomplished over leased
telephone lines, fiber optics or our Wireless
System. Each of these methods uses continuously
available links to distribute the audio in real
time, guaranteeing that all stations are
broadcasting current message content.
Leased Telephone Land Lines
are universally available as a means to link
audio, though audio quality and delays can be
Fiber Optics is an excellent
way to distribute audio to synchronized
stations, if the infrastructure is in place.
*Wireless Audio Link (WAL) System, which offers
the following advantages:
Fully under your ownership and control.
No monthly cost to operate.
Excellent signal quality.
Unaffected by power outages when generators
or battery backups are present at the
satellite radio locations.
Unaffected by weather disruption that can affect
phone and fiber lines.
Licensed, protected VHF frequencies.
The standard package includes . . .
Wireless Audio Link transmitters
Antennas and mounts.
Cable, arrestors & converters.

and support poles.
The Wireless Audio Link system is analog based
and does not depend on digital or IP-based
equipment to function.
If satellite stations are fewer than 15 miles
apart, we recommend GPS Frequency Stabilization
to prevent inter-station interference
Wireless Audio Link range is up to 20 miles,
quasi-line-of-sight. Low VHF operating
frequencies will accommodate some terrain and

Information Radio Stations is a generic term synonymous with Travelers
Information Stations (TIS), Highway Advisory Radio Stations (HAR) /
Highway Information Systems & Low Power Radio Stations (LPR). Operation
of the stations is governed by FCC Part 90.242 Rules. A FCC license is
required. Information Radio Stations may be fixed or portable.
Subcomponents may include transmitter, antenna and ground system,
digital voice player, wattmeter, cabinet with conventional or Corbin
locks, lightning arrestors for RF, power and telephone lines, coaxial
cable. Most stations employ black maximized antennas to discourage ice
accumulation and security measures to prevent unauthorized program
access. Options include synchronization, battery backup, solar power,
remote programming by local, network or telco, multi-station audio
distribution via RF or LAN / WAN or wireless network.
