Abstract

This work represents an effort to support an on-going project by characterizing the wireless communication link of a teleoperated robot. The purpose of this research is to make the robot operational using its untested 802.11n wireless technology, to define measurement and experiment procedures for testing the link performance, and to make preliminary measurements of the robot's communication link. (The 802.11n standard is said to have better multipath performance than the earlier 802.11g standard with which the robot had previously been equipped.) By installing network performance software on both the robot and its base station, the wireless communication link is tested for throughput and packet loss rate. These tests are performed in both line-of-sight (LOS) and non-line-of-sight (NLOS) environments. It is found that the robot's wireless configuration provides LOS communication with relatively high throughput and minimal packet loss over at least 400 feet, while in NLOS environments, the signal can fade completely in a much shorter distance.
