TaitNet QS² Simulcast broadcasts simultaneously from several transmitters on the same frequency. The transmitters then operate as a single transmitter giving superior coverage.

Reliable Performance

TaitNet QS² Simulcast uses Digital Signal Processing (DSP) technology to simplify and improve on the traditional form of simulcast - the transmission of the same frequency from multiple transmitters. DSP gives highly stable equalisation characteristics, which do not drift over time.

DSP techniques and computer control combine to make an advanced system that virtually eliminates the expensive and regular maintenance normally required to ensure clear audio in area where transmitter coverage overlaps.

Superior Coverage, Enhanced Reception

Wide area coverage is achieved using only a single frequency pair, eliminating the need for multiple channel licences and releasing precious frequency spectrum. QS² Simulcast can saturate a local area providing coverage in traditional 'dead spots' like large buildings and parking basements.

Superior Audio

Full audio bandwidth gives crystal clear audio. About 400 staff from three law enforcement agencies in Sonoma County, California, use a five channel TaitNet system. "The audio quality is distinctly better than our previous system," says Joe Perez of Sonoma County.

Seamless Roaming Between Sites

Because simulcast is a technology that provides wide area coverage from one frequency pair, users can travel throughout their area of operation without needing to change channel. It's so simple to use that mobile staff don't require training when you upgrade to a simulcast system.

Fast, Multi-Site System Access Time

System access is at the press of a PTT button, giving fast wide area multi-site operation.

Easy to use All-Informed Network

The open channel provides instant contact between all users for the fast, efficient sharing of information. The single button press-to-talk operation also reduces the workload for despatchers.

Modular System

TaitNet QS² Simulcast is designed and configured to a customer's precise needs and can be easily expanded in the future. The system control equipment takes up just 3U of rack space, reducing site installation and operation costs.

Compatible with Existing Equipment

The cost of upgrading to QS² Simulcast can be reduced by using the control equipment with existing base station infrastructure, and mobile and portable radios. QS² Simulcast also supports encrypted radios.

Multiple Link Types

The system supports the use of different link types for different sites.

Automatic Adaptive Audio Equalisation

TaitNet QS² Simulcast is believed to be the only system that automatically equalises the three key parameters of system audio: bulk delay, phase delay and amplitude. The Line Equaliser Module (LEM) is self-adaptive. It analyses the characteristics of its neighbouring transmitter and adapts its own characteristics to match.

This process is known as training. It completely eliminates the need for manual measurement and adjustment of parameters. Any realignment that is required takes place in less than 20 seconds per transmitter.

Generic System Configuration

The system can be configured with any standard VT100 terminal. All system control functionality is embedded in the Central Site equipment.

Stored Back-up Configurations

A full set of equaliser co-efficients can be preset and stored for a back-up/redundant site link path. This provides immediate switchover to an alternate site link if there is a fail alarm from the main site link.

Comprehensive Selection of I/O for Integrators

TaitNet QS² Simulcast represents 10 years of Tait experience with simulcast systems. A range of inputs and outputs are provided to give solutions to the many and varied scenarios that can be encountered. These include:

  • Disable remote noisy receiver
  • Change channel on monitor receiver
  • Pre-emphasis selection
  • Site busy indication
  • Link fail indication
  • Train system input
  • Site transmitting indication.
