Robotics-Based Location Sensing Using Wireless Ethernet

Tags:
ethernet

Overview A key subproblem in the construction of location-aware systems is the determination of the position of a mobile device. This paper describes the design, implementation and analysis of a system for determining position inside a building from measured RF signal strengths of packets on an IEEE 802.11b wireless Ethernet net-work. Previous approaches to location-awareness with RF signals have been severely hampered by non-linearity, noise and complex correlations due to multi-path effects, interference and absorption. The design of the system begins with the observation that deter-mining position from complex, noisy and non-linear signals is a well-studied problem in the field of robotics.

Peter Cochrane's Blog: Searching for wi-fi in Norwich

Not a sausage - no signals, no users and no nodes in evidence. Perhaps the muninet boys were having a bad day, and I was too - I had just wasted two hours footing it around the city looking for wi-fi signals in the streets and in stores and shops.
