Great ThinkPad Hack: Wireless Site Surveys
Wireless site surveys are indispensable for developing accurate data models of network coverage in a variety of environments. Current options for creating a signal-strength map of a large area require time-consuming manual operations to designate points and record signal strengths. ThinkPads with the Hard Disk Active Protection System (HDAPS) accelerometers allow for the automation of much of this work through computed distance traveled and signal-strength measurements.
Use the accelerometer embedded in a ThinkPad to record your movements while monitoring your network connectivity. Use custom algorithms to extract footstep features from the recorded data, then automatically plot signal strengths on a floor-plan map to determine the best areas of coverage.
Requirements:
A ThinkPad that supports HDAPS.
You need a Linux distribution with kernel support for HDAPS. The HDAPS driver must be included in the kernel to enable access to the accelerometers. Newer kernel distributions, including Red Hat, Debian, Gentoo, and Ubuntu include HDAPS drivers.
Take your ThinkPad out for a walk to create wireless site surveys
