Critical communications solution tailored to your industry

Uninterrupted voice and data connectivity

PRISM PTT+ is a hybrid communications system leveraging LTE and satellite connectivity to increase resilience and coverage. It is a user-friendly voice and data solution turning Radio systems (LMR/DMR), Cellular devices (3G/LTE) and Satellite networks into one unified network.

The solution provides real-time voice and data across the multi bearer environment. PRISM PTT+ is easy to scale, deploy and manage and the perfect solution to cost effectively extend radio networks to any coverage area without building expensive ground infrastructure.

With crystal clear voice and uninterrupted data connectivity in even the most remote locations, PRISM PTT+ is the most cost-effective and dependable critical communications platform available today.

Your link for resilient and unified field communication

The EXPLORER Mobile Gateway harmonises diverse Land Mobile Radio (LMR) networks. It seamlessly extends LMR coverage and capacity from line-of-sight to beyond-line-of-sight so that workers can enjoy the safety and operational benefits of voice and data communication coverage in areas where they would previously have been ‘off-grid’.

Our technology connects essential personnel and equipment to a unified, redundant critical communications ecosystem.

Integrated with existing radio solution

With voice protocol optimised for satellite and poor link conditions at the edge of radio coverage, PRISM PTT+ expands your existing radio solution for reliable coverage anywhere. It interconnects seamlessly with any LMR system transforming your existing portable and in-vehicle VHF/UHF devices to beyond line-of-sight. Reliability is high and roll-out is simple, with a staged, ‘one radio at a time’ process developed to ensure simplicity and redundancy.

Seamless switching between networks

The most crucial element of field communication is clarity, which can only be achieved with a stable and reliable line. PRISM technology provides network resilience and enables immediate switching between networks depending on the current link conditions. Even mid-transmission, PRISM can seamlessly switch networks without dropping out for even a millisecond, providing unmatched stability and reliability in every transmission.

Global, beyond-the-horizon coverage

Expand your coverage area immediately by utilising the coverage of the biggest service providers within terrestrial and satellite communications. PRISM leverages Internet Protocol (IP) traffic, which means that with just two pieces of equipment, global coverage is easily achieved. When your current radio system is integrated to PRISM, all your in-vehicle and personal radios become beyond-line-of-site, instantly.

Future-proof network compatibility

The EXPLORER Mobile Gateway utilises up to three different networks simultaneously. For instance, it can be configured to monitor Inmarsat BGAN, a LAN and a 3G/4G service and will automatically select the lowest-cost stable link intelligently and based on user-defined settings. And because the unique design of the Mobile Gateway is network agnostic it is already compliant for use with future networks including 5G, and future LEO and MEO satellites.

Secure voice and data communications

To ensure secure communication, all communication between the EXPLORER Mobile Gateway and the PRISM PTT+ system is encrypted with AES256 CTR encryption. Installed Mobile Gateways are equipped with a hardware security chip to ensure unique identification and safe provisioning into the network and any systems that may be lost in the field can have its network permissions remotely revoked quickly and easily.

Business and service continuity

PRISM PTT+ can be configured as a turnkey solution with all elements of the service – including deployment and management of the communications server – delivered by Cobham SATCOM. This reduces the technology know-how your organisation needs to significantly improve its field communications coverage and capacity. The package is completed with 24/7 global support to always ensure high service availability.
