The TORNADO MRCC™ Digital Multirole Communication System is specifically designed to support all types of control rooms from very small to very large centres.

 

Since the first production model, hardware and software have been augmented to suit a variety of users including police, emergency services, civil defence, private security, border and harbour patrol and various financial institutions. Its ease of operation is an asset to its integration into control and emergency centres.

 

Each system is tailor-made to meet the client’s exact requirements on a simple ‘plug and play’ basis.

 

Designed from the outset to integrate call taking and dispatch functions into a single system by combining digital and analogue telephony and radio control.

 

The System features the ability to interface with all standard types of communication circuits and has been designed to cater for interface modules providing communication to specialised circuit types.

 

The TORNADO MRCC™  employs distributed processing to provide maximum reliability and allowing new functions to be added at any time while maintaining compatibility with the existing modules.

 

Employs modular concepts to facilitate expansion thus ensuring maximum flexibility.

 

Based on a distributed architecture with built-in redundancy to ensure 100% uptime.

 

The Tornado Multirole Communication System combines all communication circuits into a single operator console.

 

The client has the ability to opt for the deployment of operator positions in the following formats:

  • Hardwired system 

  • VoIP

  • Browser Based

The communications system can be accessed from an operator position based anywhere in the world with full centre functionality when Browser Based operator consoles are employed.

DIGITAL RADIO TECHNOLOGIES

Digital Radio Technologies – Reference Information

TETRA

Tetra employs four-slot TDMA in a 25 kHz frequency channel.

Most suited where there are a large number of users in a small geographic area.

Very expensive to deploy for wide-area radio networks where RF coverage is key.

To cover the same area as analog, approximately 3 times the number of repeaters are required. More repeaters may be required depending on the geographical features.

A much smaller range of frequency bands is available for 25 kHz channel spacing.

Data throughput for Tetra is theoretically the highest, although seldom employed at a higher rate than 10 Kbit/s.

No analog migration is possible, the entire network and devices need to be converted simultaneously.

 

DMR

DMR employs two-slot TDMA in a 12.5 kHz frequency channel (6.25 kHz per timeslot).

Compression techniques allow speech to be transmitted in a single 6.25 kHz slot of the 12.5 kHz channel and therefore a second channel of 6.25 kHz is available for speech or data.

When operated in Tier 3 mode (trunked), the two channels can be used for full-duplex speech, for data at higher speeds or one for speech and one for data.

The RF coverage for DMR is approximately the same as for analog.

Owing to the technique of digitizing the full 12.5 kHz band, existing sites used for analog can be converted for DMR operation.

For the same reason, networks can easily be migrated on an area by area basis.

Data throughput is 9 Kbit/s when both timeslots are used.
