Abdo A. Husseiny, Golden G. Richard III, Yun Gao, Zeinab A. Sabri (June 23, 2003). Develop Wireless LAN Design & Validation Tools. TII-VA Report # TILA-020308-osdwt01; Contract # N00178-03-C-2008; Dahlgren Division; Naval Surface Warfare Center.



This project addresses the development of working models of WLAN DesAnVal, a suite of Wireless Local Area Network (WLAN) Design and Validation (survey) tools to reduce the time and effort spent in what is currently a trial and error process for each installation. The tools are developed for use during a site survey in complicated military environment where there is vulnerability to security, electromagnetic interference (EMI), radio frequency interference (RFI), and ordnance.

EMI/RFI generators on platforms, such as electronic equipment, microwave ovens, and rogue APs that will degrade the performance of the WLAN if not compensated for in the design. Military environments with steel walled compartments can be very difficult when it comes to positioning RF equipment, due to obstructions and combinations of both large and small spaces.

The WLAN DesAnVal capability encompasses: (1) a survey tool that uses a directional antenna to determine, measure, and locate sources of EMI/RFI in the 802.11a/b spectrums; (2) a survey tool to determine when multi-path interference (MPI) will be encountered; (3) aid in determining a method to eliminate/reduce the impact of EMI/RFI/MPI on the WLAN; (4) a tool to generate traffic at adjustable rates (packets of adjustable size) and measure the throughput, errors, and collisions between any two points on the WLAN; and (5) measure the nominal transfer rates of the most commonly used Internet Protocols (IPs); such as the Transmission Control Protocol (TCP), User Datagram Protocol (UDP), and Internet Control Message Protocol (ICMP) between certain critical points in the WLAN, such as uplinks to core and distribution devices or between clients and Access Points (APs).

The working models of the WLAN DesAnVal tools comprise adapted state-of-the-art Components-Of-The-Shelf (COTS) as the hardware tools and mapping software for site survey, in addition to custom-made software tools for traffic generation, site mapping augmentations, and link analysis for pre-survey planning and survey validation. All tools are selected and/or developed to work in complex military environments, are optimized for minimal life-cycle costs and are geared to provide the basis for development of an integrated WLAN DesAnVal prototype level functioning tool.

Production level products of the WLAN design and validation tools have value in both of the commercial and government sectors. The WLAN DesAnVal tools especially meet the needs of Navy ships, military mobile platforms, Army proving grounds, and commercial boats. Potential commercial applications encompass military bases, the defense industry, NASA repair and maintenance shops, nuclear facilities, chemical and petrochemical industries, factory floors, communication and data transfer between downstream and upstream operations in factories and assembly lines.
