Now that most people have cellular phones making them work at sea has been one of the next steps forward for cruise lines. Thanks to the InterReach Unison and Wireless Maritime Services WMS cellular service has taken to the sea and Island Cruises was among the first to offer it. A joint venture of Royal Caribbean Cruises Ltd. and First Choice Holidays Island Cruises offers cruises of the Mediterranean in the summer and transatlantic cruises to Brazil during the northern winter. Its ships the Island Escape and the Island Star each carry 1740 passengers and 550 crew members and feature 770 passenger cabins. Founded in 2003 as a joint venture between Cingular Wireless and Maritime Telecommunications Network MTN WMS is a one-stop vendor that deploys shipboard cellular systems integrates them with MTN s satellite data network and then routes calls to the caller s home network through Cingular s roaming agreements with more than 250 cellular carriers worldwide. Most of the world s cruise lines already use MTN s satellite network for data services such as onboard Internet access so it was relatively easy to add cellular traffic to these links. CASE STUDY The challenge was to extend cellular coverage throughout a ship. Ships are problematic for cellular coverage because their steel construction interferes with wireless signals. Delivering on-board coverage requires installation of a distributed antenna system but installation of these systems can be difficult because of the tight spaces allowed for communications cabling on ships. But with the Unison system Wireless Maritime Services WMS overcame these problems. The system s active electronic architecture ensures that each of its remote antennas delivers maximum signal strength to a specific area. And the system uses standard multi-mode fiber
