Hey guys,
I have an app that the protocol requires fast responses or low latency.
The problem I am seeing with 8022.11b radios is that occasionally the radios will go into a state where there are many retires then rts/cts kicks in and everythng slows down.
The data rate also scales down to 2mbs. I will then get packets that will burn thru all the retries and rts/cts and still not get there ack.

All this will happen for a few seconds and then the application will return to working normally for a couple more minutes.
My RSSI is good and I do not have any other interferences.

My question is; is it normal for the data rate to scale down for retries? I know that after a rts/cts the next packets rate will be 2mbs. But should
all packets scale down if there is excessive retries or traffic? Also how abnormal or what could possibly happening that a packet using rts/cts does not get a ACK?

My packet rate is about 600 packets per second and ~ 100 bytes per packet.

Regards

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.
