Imagine a bank where every cashier had their own queue and you, the customer, could not change queues. You could be standing waiting for service while a neighboring cashier had no customers. Placing a call on a conventional radio system can be just as frustrating. Your channel may often be busy while neighboring channels are available and under-utilised.

Conventional ATM.	Trunked ATM.

Just as a modern bank provides access to a pool of cashiers, trunking provides access to a shared pool of radio channels. When you want to place an individual or group call, a channel is allocated to all participants. The call takes place in private and once it's completed, the channel is returned to the pool for others to use. Sharing channels increases the availability of airtime to all users. The result is increased quality of service and reduced infrastructure and operating costs.

British Ministry of Post and Telecommunications (MPT) defined the MPT 1327 protocol in 1988 as an open protocol and an international standard, it has since become the most widely used trunked radio protocol in the world.

MPT is just like the PC which has been around for some time but their performance today would never be likened to the PCs of the 1980s. It is important to remember that MPT is a digital trunking system. The call set up and all signaling for data is digital. Only the voice on traffic remains analogue. We consider this to be an advantage where speech clarity is paramount.

MPT 1327 trunking is ideally suited for providing individual or group calls, it offers fast call set up time along with a wide range of advanced features and functionality. Examples of such features include emergency and priority call management, status messaging, dynamic regrouping of users, and data/text messaging.

MPT 1327 uses a digital control channel with analogue voice channels. The digital control channel provides a data gateway that allows enhanced features including security and subscriber verification, mobile data communications, system administration, and seamless multi-site roaming.

Emergency Services

The 22 site MPT 1327 system delivers county-wide radio coverage with telephone-grade speech quality, it also provides telephone integration, an automatic vehicle location capability and data facilities with mobilising message delivery in under 2.5 seconds.

“We’ve been absolutely delighted” says Assistant Chief Officer Steve Webster. “We’ve actually got a far better level of coverage than we ever anticipated.” The new system with its superior wide-area coverage and superb performance has left Cornwall Fire Brigade in the odd position of having a secondary network that out-performs their primary system in every way and is far cheaper to run!

This regional system was installed and is maintained by Gould Electronics. The 22 site public access system also supports other services such as Cornwall County Council, Doctors, Vets, Security, Taxi companies & shop watch schemes.

Shop Watch Schemes

Shoplifting costs retailers in the UK around £3 billion a year. Shop watch communication schemes help tackle the problem.

Help prevent shoplifting and credit card fraudsters from going unrecognised by circulating suspects' descriptions to other members of the scheme and the police.
In almost all shop watch schemes the police are actively involved, relying on information to apprehend suspects.

The Trunked shop watch system has the Potential to deliver county-wide radio coverage with telephone-grade speech quality, it can also provides telephone integration facilities.

We offer handsets on the Camborne / Redruth scheme from £5.00 per week on a rental basis which includes maintenance and licensing, and from £10.00 per month if the radio unit is pre-purchased.

Cornwall County Council

The system is used by Cornwall County Council’s Estates & Highways Departments as their primary system.

The 22 site MPT 1327 system delivers county-wide radio coverage with telephone-grade speech quality, it also provides telephone integration, an automatic vehicle location capability and data facilities.

This regional system was installed and is maintained by Gould Electronics. The 22 site public access system also supports other services such as Cornwall Fire Service, Doctors, Vets, Security, Taxi companies, shop watch schemes, Haulage & Waste disposal.

Veterinary Care

Clear, on demand communication in rural areas is a challenge for any technology; for example, cellular phone coverage is sparse and un-reliable as coverage follows revenue. Few local users results in poor or no coverage

Gould Electronics on the other hand delivers telephone grade speech quality throughout the rural areas of Cornwall. The radio system is capable not only of delivering clear speech but it also offers the capability for vehicle location and calls to telephone land lines.

Penbode Veterinary Group supports the rural farming community in Cornwall. Practice Manager Ian Lorraine says “On demand communication is essential for the efficient day to day running of the practice. Often our vets are out all day and at night. Reliable communications allows us to keep in close contact offering help and support where required. Gould Electronics’ radio network offers us a grade of service at almost every location we have ever been in the county. Our clients benefit from quicker response times and we benefit from the health and safety aspect for our vets”. The radio network has a direct link to a message handling service for contact in out of hours situations.

Hoopers Haulage...

Hoopers Transport is based in Cornwall in the Fraddon area. Hoopers Transport is involved in the transportation of hardcore from quarries and depots to customer sites in and around the Fraddon area. Hoopers Transport came to Gould Electronics looking for a reliable solution after disappointments with cellular coverage.

Coverage is Paramount:
Radio’s must be in service In the quarries and the remote location on route. for example: access to some customer site’s are down single track lanes. These lanes are regularly being used by several of the HGV fleet at once. A vehicle to vehicle down a narrow mile long lane is a big problem.

Gould Electronics has the perfect solution:
Rugged vehicle mounted radios allowing communications with one another and the dispatcher office. All this is made possible via Gould’s county wide MPT1327 trunk radio network.

Features used by the company include:
• Person to person calls.
• Dispatcher to person calls.
• Data messages.

Future Upgrade
Hoopers Transport is planning to upgrade the system in 2009 to include Gould’s GPS tracking and vehicle management over the trunked radio network.

Difficult Coverage? No problem..

A Single Channel Cell Extender system is the perfect, low cost tool for seamless MPT1327 infill in ‘local’ areas like buildings or basements, or to cover areas where the traffic demand simply does not justify more elaborate (and far more expensive!) solutions.

Key Features..

• Creates a new MPT1327 site, by seamlessly mirroring an existing MPT1327 (Donor) Site onto a new MPT channel frequency.
• Does not require expensive microwave links or land lines, nor any changes to the Parent Network infrastructure.
• Easily installed, true plug and play package.
• Readily upgraded to future Multi channel operation.

In System Example...

Mobile Repeater (G2 Smartbridge)

A G2 Smartbridge Mobile Repeater system will make a “local” conventional radio network (e.g. a small fleet of one or more conventional portable radios) fully transparent to the wider Trunked network, by intelligently cross connecting a conventional radio and a trunked radio, which are both installed in a “base” vehicle.

Key Features..

• Provides Full MPT1327 functionality in difficult coverage areas. For example: basements, In Building and Geographic areas where a mobile unit can be dispatched.
• Vehicle mounted equipment for easy deployment.
• Emergency and data features.
• Lone worker safety (Personnel working away from their vehicle with a handheld radio will be linked via the vehicle to the dispatch office or a co-worker)
