Evaluation
This chapter seeks to evaluate the measurable affects of the limiting factors outlined
in sections 1.3.1 and 2.1.2 on the implemented application.
6.1
6.1.1
Testing
Test Environment
The testing was performed in a test environment with as little interference as possible,
i.e. no 802.11 activity was taking place. Two Nokia 6600 handsets were used to conduct
the tests. Identical MIDlets were installed on each device. The mobile phones had full
battery life on commencement of testing.
6.1.2
Discovery
Bluetooth is entirely responsible for devices discovery. The tests revealed that discovery
did not work at every attempt. Discovery was successful in approximately 90 percent of
tests conducted. The length of time consumed before discovery allowed a connection to
be established ranged considerably. An average time of 30-90 seconds was calculated,
with the quickest being under 10 seconds, and the longest being almost 3 minutes.
