Today it is important for Navy ships at sea to be able to communicate and exchange information with a shore network for services such as file transfer, database access, e-mail, web/intranet browsing, or video conferencing. To accomplish this, most ships use satellite communications, which is an expensive and slow method. When a ship is near shore, it can use alternate methods of communicating with the shore network that are typically faster and cost less than satellite-based services. Examples of these methods are IEEE 802.16 WiMAX, 2.5G/3G/4G cellular networks, and Wave Relay systems. This paper evaluates the various methods available in terms of cost, range, bandwidth, quality of service (QoS), and reliability, by conducting experiments in Monterey Bay, CA. The experimental results are reported and used in this paper to determine which method would be best suited for various use cases.
