PW0-270 · Question #50
In the analyzer trace shown, the TBTT is nominally 102.5 milliseconds. Why does the Beacon transmission interval vary?
The correct answer is A. The access point must arbitrate to gain access to the RF medium in order to transmit a Beacon. See the full explanation below for the reasoning.

Exhibit
Options
- AThe access point must arbitrate to gain access to the RF medium in order to transmit a Beacon.
- BThe DCF Interframe space (DIFS) is nominally 50 祍, but typically varies by as much as 10 祍,
- CThis trace shows an HT network where HR/DSSS nodes are active on the network. The access
- DBeacon frames vary in size, and therefore some take slightly longer to send than others.
