Experiments:

Introduction to course experiments:


1. Signal strength measurement for wireless access points

The goal of this lab is to understand the coverage model and channel characteristics of 802.11 Wireless LANs. Students are guided to use PocketPC (or their own laptop) computers and detection/visualization software to perform various WLANs coverage studies. With this lab, students will be able to understand how to detect 802.11 LANs, identify access point locations, and find coverage of 802.11 networks. This experiements consists of two parts - indoor coverage experiment(use Netstubler) and ourdoor coverage experiment(use Wififofum and Knsgem). Each group is required to check out GPS-enabled PDAs(HP iPAQs) or bluetooth-GPS from the lab for outdoor coverage experiment.

2. Bluetooth encounter

The goal of this lab is to understand a possible scenario of delay tolerant networks (DTNs) via short-range radio (e.g. Bluetooth) on the portable mobile devices. Students will gain hands-on experience to explore the chances for inter-device communication through collecting Bluetooth encounter traces, post-processing and analyzing the traces, comparing it to other encounter traces and brain storming on how to utilize this encounter information in DTNs. Each group will check out several devices (Nokia N800, Nokia N810, HP iPAQ or Openmoko) for trace collection, and carry them as often as possible during suggested period.
