What is the maximum range for using the infrared wireless port when updating a PDA from a laptop?
1. 100 feet
2. 5 feet
3. 30 feet
4. >>20 feet -->Correct
Explanation : The maximum range for Infrared Data Association (IrDA) devices is no more than 20 feet. It is typically given as 10 to 20 feet, but it can be affected by ambient light (if it is too bright) or dust. It also requires unobstructed line of sight between the devices.
The range is greater than 5 feet. If the devices are unable to communicate at less than 10 feet, you should suspect problems.
Both 30 and 100 feet exceed the maximum rated range for IrDA devices. If these ranges are required, other interface types should be used.
