Hi all,

I just want to know at what speed the beacons are transmitted on wireless network.

TIA

They should be sent at a BSS basic rate. It seems to depend on AP manufacturer. For HR-DSSS and ERP-OFDM, default BSS basic rates on most APs include at least 1 and 2 Mbps.

Some APs always send beacons at 1Mbps, some will send at 2Mbps. I did a quick scan using OmniPeek, which shows about 3 mixed mode BSS transmitting beacons at 1Mbps and 2 transmitting beacons at 2Mbps.

If your AP is transmitting beacons at 2Mbps or a higher basic rate if set, this may decrease your APs range. Beacons sent at 1Mbps would give the greatest range. I don't think the beacon data rate is generally tuneable - does anyone have any experiences with this?

Success Stories

I literally just came out of the testing centre having taken the CWDP exam. The certification process opened my mind to different techniques and solutions. This knowledge can only broaden your perspective. Great job, CWNP, you have a great thing going on here.

Working through the CWNP coursework and certifications helped not only to deepen my technical knowledge and understanding, but also it boosted my confidence. The hard work it took to earn my CWNE has been rewarding in so many ways.

I want to commend you and all at CWNP for having a great organization. You really 'raise the bar' on knowing Wi-Fi well. I have learned a ton of information that is helping my job experience and personal career goals, because of my CWAP/CWDP/CWSP studies. Kudos to all at CWNP.
