Suppose that an 802.11a device moves away from a transmitter. As the signal strength decreases, which one of the following might the device or the transmitter do to improve the signal quality along the way?
- Aggregate more channels
- Use more radio chains
- Switch to a more complex modulation scheme
- Switch to a less complex modulation scheme
Explanation: By switching to a less-complex modulation scheme, more of the data stream can be repeated to overcome worsening RF conditions. This can be done automatically through DRS.
