Communicates Critical Information Instantly
VoiceStar is a portable information station plus changeable message sign, ready to roll.

Notify the public at highway construction zones, traffic incidents, safety and health emergencies and major events. Stations are often integrated into a system of several units to instantly notify the public at highway construction zones, traffic incidents and in health and safety emergencies.

Powered by a robust array of solar panels and battery backup, VoiceStar stations can go anywhere, anytime. They are built to operate in isolated locations for weeks at a time. The radio messages and sign text may be programmed locally or remotely via cell modem.

VoiceStar has 'quick startup' and can be broadcasting and/or providing its message display in fewer than 5 minutes.

After parking the trailer, the operator swings up the antenna, lays out the portable groundplane and flips on the power. Batteries are immediately online. If AC power is available, the operator has the option of plugging in and charging the system’s batteries while operating. The solar array is aligned to allow positioning of the trailer in any roadway orientation.

VoiceStar's groundplane system offers a signal range to match that of fixed information radio stations (25-75 square miles). But only VoiceStar provides the option for 2 transmitters – of the same or different frequencies – in the same cabinet, with single-switch changeover between transmitters. This allows the operator to change frequencies or change to a backup transmitter on the fly.
VoiceStar's bright lensed-LED changeable message sign in the standard character matrix format offers many message programming options.

Every VoiceStar system comes stocked with prerecorded external messages prepared by professional announcers. You may commission additional recording services for dated messages. In addition, AAIRO members who operate VoiceStar systems can access a professional broadcast message recording service at no charge during the lifetime of the system.

Information Station Specialists supplies Remote Technical Support and Potential Interference Notification Services (PINS) for the life of each station.

VoiceStar systems are made available in partnership with the American Signal Company.

Broadcast Content Frequency & Licensing
Information radio stations may broadcast content relating to public safety and travel, such as road conditions, weather, directions, emergency and other general interest topics to motorists.

Broadcasts must be voice-only with no commercial content.

See our Permitted Broadcast Content webpage for details.   
VoiceStar Portable Information Radio Stations are licensed on frequencies 530 to 1700 kHz AM, secondary to standard AM broadcast stations. 

Via solar wireless communication, operators can program broadcast messages and the changeable sign display remotely. Range is 3-5 miles (25-75 square miles) across average terrain. The FCC’s special “broad area” license (good for 10-years and renewable) affords operators a territory in which each VoiceStar may roam. Licenses can also specify a fixed operation point, if desired.

See our Frequency/Licensing page where you can download a form to complete and return, requesting this service.
