Question
A consultant is called in to help troubleshoot connectivity problems an office is experiencing with their 802.11a wireless network. The office manager reports that at random times during the day, workers will lose wireless connectivity for different spans of time. There is no pattern to the drops in connectivity. Which of the following causes should the technician explore FIRST in troubleshooting the office issues?
Options

Explanation
802.11a operates exclusively on the 5 GHz frequency band. A 5 GHz portable phone system would directly compete for the same radio frequency spectrum, causing intermittent interference and random connectivity drops - exactly the pattern described. 2.4 GHz phones (A) and microwave ovens (B) operate on the 2.4 GHz band, which does not overlap with 802.11a's 5 GHz band and would not cause interference. Two-way RF radios (D) typically operate on frequencies well outside the 5 GHz range. The 5 GHz phone system is the most likely culprit and should be investigated first.
