Over the Ocean RF Propagation Modeling and System Design for Wireless Broadband Systems
The research presented in this document considers the development of a terrestrial wireless communication system for providing connectivity to vessels within coastal waters. The system operates in the 2.4GHz ISM band and can provide throughputs that are on the order of 1-20Mbps. Several important aspects of the system design are considered. First, the propagation path loss in the2.4GHz band over the coastal water is characterized. The characterization is performed through an extensive measurement campaign. A practical propagation model is developed. Second, since 2.4GHz is an unlicensed spectrum, it hosts many other wireless systems. These systems create substantial noise in the band. The research presented in the document performed the characterization of this noise. The characterization was performed through an extensive measurements campaign. A theoretical model for the noise floor is developed. The model is calibrated and verified using measured data. Finally, a nominal system design is performed for the coastal area of Brevard County, FL. The performance of the nominal design is accessed through computer simulations.
