Comprehensive Spectrum Management for Wireless Networks

Wireless local area networks (WLANs) have become standard technology for government, commercial business, and DoD networks. With this widespread proliferation of RF technology has come a myriad of problems such as how to architect the WLAN for optimum performance, how to easily set-up and configure the WLAN and how to secure the WLAN to protect it from hackers. Solutions for such problems are available and still evolving. However, a newly recognized and just as insidious problem has gotten a lot of attention recently; that is the problem of Spectrum Management. Develop advanced hardware and software technologies for analysis and management of the RF component of shipboard wireless networks. In this SBIR Phase I we plan to demonstrate the feasibility of spectrum management for a wireless network system that utilizes the common unlicensed frequency bands and has the ability to shift to other desired frequency bands. The solution developed will address improvement of throughput through avoidance of interference as well as the ability to avoid the usage of specified frequencies when required by policy. We will accomplish this through the use of extensions to an existing WLAN Management System coupled with adding special purpose spectral analysis ICs to wireless Access Points. Comprehensive spectrum management will include provisions for spectral analysis and characterization as well as RF emitter location techniques. Advanced power management coupled with the use of directional and smart antenna technology is another key aspect of this project. The primary focus will be development of system suitable for handling the complex shipboard RF environment. The system will be capable of being used for Naval and military applications, including requirements for ruggedization, electromagnetic compatibility, information assurance and open architecture. The developed solutions will also have applicability for typical shore-based installations as well.
