Performance of the IEEE 802.11b WLAN Standards for Fast-Moving Platforms

Kasch, William T., Burbank, Jack L., Andrusenko, Julia, Lauss, Mark H. 10 1900 (has links)
International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada / This paper addresses the physical and MAC layer performance of the IEEE 802.11b wireless local area networking (WLAN) standard in range-extended outdoor applications for high speed network platforms. Physical layer performance is quantified by bit error rate (BER) and packet error rate (PER) vs. range performance as well as acquisition and tracking performance considering Doppler effects caused by such high-speed platforms. This performance assessment is ascertained through the use of modeling and simulation and hardware-in-the-loop testing.

RT TELEMETRY NETWORK UPGRADE BASED ON ETHERNET

Taylor, Gene 11 1900 (has links)
International Telemetering Conference Proceedings / November 04-07, 1991 / Riviera Hotel and Convention Center, Las Vegas, Nevada / New techniques for using Ethernet in real time systems are applicable to the typical requirements of high performance Telemetry installations. Most TM installations around the world today are currently implemented using specialized, high speed, point-to-point data paths which have reached their limits in performance. By using Ethernet in real time as a “Data Highway” path, system performance is optimized, and the effective life of a Telemetry system can be significantly extended. Additionally, by integrating a Local Area Network into the system, further advantages are realized. New graphics display hardware and software may be used to provide virtually an “offthe-shelf”, and very cost-effective major system upgrade. Meanwhile, little modification to the host processor hardware or software system is required. This paper examines these premises, and discusses several examples of major Telemetry systems which have made this upgrade.

Network Telemetry: Practical Experiences and Unique Features

D’Amico, William P., Stadter, Patrick A., Lauss, Mark H., Hooper, Andrew 10 1900 (has links)
International Telemetering Conference Proceedings / October 21, 2002 / Town & Country Hotel and Conference Center, San Diego, California / The US Army’s Yuma Proving Ground (YPG) uses a wireless local area network (WLAN) to gather test data. It is desired to extend this WLAN to support tests of gun-launched munitions where miniature and rugged data acquisition hardware will be required. The Two Way Robust Acquisition of Data (2-RAD) program has been initiated under the Central Test and Evaluation Investment Program (CTEIP) to develop a process to expand the use of WLAN technology, which is now primarily used at YPG for internal ballistic test data acquisition.

OptoNet- a non-directional infrared communication link for local area networks

Liu, Dongtai 05 December 1990 (has links)
This thesis work researches the theory and application of systems performing omnidirectional, non-direct path optical data communication (ONP systems). Such systems are characterized by 1) the communication involves a local, usually circular area; 2) Obstacles are allowed between a transmitter and the receivers. This is in contrast to the point-to-point and line-of-sight communications performed by almost all existing infrared data communication or transmission systems. The elimination of the point-to-point limitation makes ONP systems suitable for optical local area networking. The feasibility of ONP systems employing infrared LEDs and silicon photo detectors has been analyzed and the performance of such systems predicted. The analysis shows that indoor ONP systems are both feasible and practical. Only a few LEDs are required to cover the entire area of a large room. Efforts have been made in finding rules for optimal design of the ONP systems. A set of design criteria and curves have been established. The theoretical analysis has been verified in a successful experiment done with OptoNet, an ONP infrared datalink for local area networks. This experimental system consists of two identical communication units employing FSK modulation and microprocessor controllers. The experiment has demonstrated that the ONP optical data communications can be realized by relatively simple electronic hardware. / Graduation date: 1991
