The InterReach Unison systems will provide GSM and CDMA mobile coverage in the ships? public areas as well as passenger cabins and crew quarters.

Each ship will typically be fitted with one main hub, four expansion hubs, and 25 remote units to provide the wireless coverage, and traffic will be connected with mobile networks on the mainland via existing satellite data links on each ship.

According to ADC, Unison systems are ideally suited for high-density environments such as ships (which pose unique wireless coverage challenges due to their myriad bulkheads and cabins), because each remote antenna unit delivers the same signal strength to ensure uniform coverage.

In addition, the Unison system automatically alerts MCP's control centre if there is a component failure so this can be patched remotely and the fault is temporarily rectified until maintenance staff can fix the problem when the ship reaches port.
