Title Connecting Land-Based Networks to Ships.
Publication Date Sep 2012
Media Count 107p
Personal Author P. Chatzigiannis
Abstract Today it's important for ships at sea to be able to communicate and exchange information with a shore network, like file transferring, database access, e-mail, web/intranet browsing, or video conferencing. Navy ships might even want to send a live video feed from the field. To accomplish this, most ships use satellite communications, an expensive and slow method. When a ship is near shore, it can use alternative methods of communicating with the shore network, which are typically faster and cost less. This thesis evaluates several such technologies to connect a shipboard local area network (LAN) to a wide-area land-based network. The equipment/hardware needed for each is described, a thorough analysis of each proposed connection implementation is presented, and the various alternatives in terms of cost, range, bandwidth, quality of service (QoS), and reliability are compared. Furthermore, experiments are conducted using cellular networks, satellite communications, 802.16 WiMAX, and Persistent Systems' proprietary Wave Relay. The results of the experiments are used to determine the method that would be best suited for various use cases.
