Low Cost Implementation of High Density Wireless Networks

"Phase II of this project will provide a prototype high-capacity frequency agile shipboard wireless LAN system. The system is intended to provide uninterrupted network connectivity in the event primary or secondary hardwired WAN and/or LAN transportsystems are compromised. The proposed system will integrated concepts and knowledge gained in Phase I to produce a hybridize wireless LAN node capable of concurrently establishing and managing three independent high bit rate (5-15 Mbps) full duplex IPbase wireless links in a dense shipboard RF environment.Fundamental to successful implementation is the ability to search and find moderately wide and relatively free spectral transmission and transmission widows over a wide controlled bandwidth. Utilizing discovery and classification algorithms investigated inPhase I together with fourth generation COTS wireless LAN integrated circuit technology, the system will be able to provide sub-second alternative back-up service to a wide range of C4I and HM&E systems.Initiated in Phase I, ongoing inter-compartment and inter-deck measurement exercises will be extended to additional vessel classes. This effort will form the basis of an ongoing propagation profiling and cataloging effort, which will be immensely useful infleet deployment.On-air system verification will consist of installing and independently testing 10 to 15 wireless LAN nodes in a variety of nominal and fault induced operational scena
