SiRRAN Communications Ltd provides world leading mobile services and solutions which range from individual secure handsets, tactical network deployment to global network switching infrastructure, which seamlessly link the full range of our solutions in a highly secure and resilient environment. The mobile handset has become the device of choice and provides a highly portable and cost effective solution to the communication requirements of Military Personnel and Government Agencies alike. While there are many technology options, the key component to any approach implemented today is the support of commercially available user devices. When the network infrastructure supports the commoditized technology at the user level, unique approaches can be taken in the infrastructure build-out to optimise the network.

Other Operators SIM - In Roaming
As determined by the individual handset registration policy of the Customer non SiRRAN SIMs can be registered to both an individual GSMnet and also the SiRRAN core. This means that if enabled handsets will be able to register and make outgoing and receive incoming calls and text messages on their mobile number. This provides a truly seamless User experience whilst builds in the controls to ensure that only authorised handsets are registered.
SiRRAN Core network
To enable multiple GSMnet systems to interwork the SiRRAN core network provides a cohesive switching matrix to maximise the benefit of a Customer owned network. The core is built around a presence engine that stores information on all GSMnets in a Customers network and also every handset that is registered to each GSMnet node this ensures that when calls are placed handset to handset on-net the most secure and cost effective path is established for voice, text and data calls. As our Customers requirements vary SiRRAN are able to build stand-alone/on premise solutions that ring-fence a SiRRAN Core behind the Customers own firewall and only access network information from our Roaming Partners when required.
