You are a help desk support technician at a retail department store and you receive a call from a manager in the administrative offices. He complains that the performance of his 802.11g/n notebook computer decreases several times throughout the day. Upon visiting the customer, you realize several people are performing inventory using 802.11b barcode scanners in the adjacent room.

Answer:

Extended Rate Physical OFDM

Explanation:

Based on the scenario being described within the question it can be said that the most likely cause for this poor performance is Extended Rate Physical OFDM. This is a technology that increases the bandwidth of 802.11 radio signals. Unfortunately this is also causing those radio signals from the bar-code scanners to increase their bandwidth and interfere with your notebooks performance.
