Hi,
We created small robot, based on Java cell phone with camera.
(See: www.RoboHobby.com)
Now we are going to create a group of small robots, walking together.
But we should decide what RF chips to use and what kind of connection technology to use.
Recently we did some tests on the fields of some typical Bluetooth and Wi-Fi devices.
We found that real outdoor range is much shorter then range from the specification.
Real distances were:
Bluetooth Class 1 devices: 16-50 meters (not 100 meters).
Wi-Fi was able to work in a distance 132 meters (not 300 meters).
Have you ever done such a distance tests?
