Ireland’s national police service, An Garda Síochána, has taken delivery of RSI’s Aries TETRA and Aries LTE network performance survey tools for monitoring their TETRA digital radio communications network provided by TETRA Ireland as well as public LTE networks. The tools will be used to identify and investigate any problems or coverage black spots in the TETRA radio network to help ensure that the Garda continue to receive the best possible TETRA service.
The Garda has a total of 14,000 officers, 2,500 vehicles and 700 stations using the TETRA radio network for their mission-critical communications. The TETRA radio network provides 98% land mass coverage across Ireland of both dense urban and remote rural areas regardless of population concentration. It also provides Air-Ground-Air coverage giving fixed and rotary wing aircraft excellent communications and a wide area communications which includes Ireland’s islands and up to 20kms off-shore.
RSI’s Aries TETRA survey tool provides near real-time TETRA network performance information and is intended to be used for the life of the network constantly monitoring and detecting any problems before the users are affected. The tool can support large numbers of monitoring probes spread over the whole country all of which log and send back data 24hrs a day to a central server for analysis.

RSI has just completed a consultancy project to analyse all radio communications to be used for Phase II Full Field Development of the Al-Nasr offshore oil field currently under development about 131km North-West of Abu Dhabi in the Arabian Gulf.
The project was carried out under contract from Atlas Telecom of U.A.E for the Abu Dhabi Marine Operating Company (Adma-Opco). The Nasr Super Complex consists of 7 separate platforms for processing, gas treatment, accommodation, utilities, flares and power distribution with interconnecting walkways and will eventually have the capacity to produce 65,000 bpd (barrels per day).
Analysing the radio communications has been a complex and challenging task involving multiple technologies including VHF Marine, VHF Aeronautical, UHF Pager, UHF TETRA and Radar. As well confirming the wide area coverage out to sea the study has analysed the indoor coverage from the radiating cable system on all floor levels of the platforms. An important aspect of the study has been to analyse potential interference issues from receiver blocking and intermodulation from so many communications systems in such a small area as well as determining the risk of inadvertent ignition of flammable gases by radio frequency radiation.
RSI has a track record of radio communications consultancy for other offshore platform projects in the Arabian Gulf including the Upper Zakum 750 project built on 4 artificial islands and the NAP demothballing project shown below:Click for pdf article
