Hosting hundreds of specialised events and catering for over 250,000 visitors each
year is a formidable task that tests even the most experienced convention centre
teams. But management at the Aberdeen Exhibition and Conference Centre (AECC)
in Scotland has always maintained that good communication is the cornerstone of
quality service delivery. To this end, the AECC has migrated its existing two-way
radio system to a MOTOTRBO Capacity Plus digital solution to further improve the
coordination of teams across this popular venue.


The AECC had been using a four-channel analogue repeater system with a variety of portable radios but there were a number of concerns, mostly notably the lack of radio coverage across the venue.

One of the reasons for this was that the repeaters and omni-directional antennas had been installed on top of a high viewing tower. They were also using radios operating in the VHF band which is not ideal for use in a building such as the AECC, where the internal walls are constructed mainly of aluminium cladding.

With a need to provide the best possible service at the centre, AECC decided to upgrade its entire communications system and subsequently chose MOTOTRBO.

“As a large venue, with separate teams working together we have the option of transmitting on departmental or company wide frequencies – which stops everyone getting every broadcast which goes out. With functionality reminiscent of a mobile phone, these handsets are brilliant for our company.”

AECC’s MOTOTRBO solution comprises 72 DP 3600 portable radios and four DR 3000 repeaters operating in the UHF band with a single down-fire antenna.

The foresight to include the intelligent software solution, Capacity Plus means the venue now has increased system capacity to link hundreds of additional MOTOTRBO radio users should they be required for special events.

The system configuration includes an all-call option, per-group option and also various sub-groups which can be easily navigated via the radio menu. The radio PTT buttons have been assigned to work in a manner that suits individual groups or sub groups, thus avoiding all radios automatically receiving general broadcasts. This means that when the PTT is pressed from an individual radio, only specific members of the group receive that call.

The teams are also using MOTOTRBO’s text messaging capability which allows for an alternative means of communicating when ambient noise levels increase to a point where it becomes difficult to hear clearly or when sensitive information needs to be sent.

And to help with operational efficiency, the AECC is using Motorola Solutions’ IMPRES smart battery technology which is delivering up to 12 hours of battery life. This was a major issue with the old system as it involved regularly swapping out batteries, causing unnecessary disruptions.



The implementation of the MOTOTRBO system has seen radio coverage and audio clarity improve dramatically which has had a major impact on AECC’s operations and bolstered efficiency overall.

In fact, there’s not a single area within the arena that’s without radio coverage.

Teams have also found that the overall usability of their radio network has improved significantly through the ability to make individual one-to-one private calls and calls to specific groups, which have cut down on radio traffic.

With the inclusion of Capacity Plus, the system can cater for extensive talk time even during the busiest periods. Adding temporary radios to the system – usually required by sub-contractors for larger events – is a simple task and the system equipment rack has been designed to accommodate four additional channels should they be needed in the future.
