Soft AP for WL1271

I have a few follow-up questions on this topic.  Let me know if you want me to take any of these offline.

• What imposes the 5 client/station limitation?
• What kind of MIPS impact is expected on the ARM per client
• How long does it take for the AP to be configured (e.g. time in seconds/milliseconds from driver load to SSID broadcast)?

Thanks,
Brad

Brad,

a. 5 Station limitation is on-chip SW limitation.

b. Less that 1 MIPS per Client is required for management. CPU load for data handling does not depend on the number of connected clients passing the traffic and is the same as for single client connected.

c. This is dependant on HLOS/Processor/Memory etc and would need to be measured on specifc platform.

Can you perhaps give a specific example?  My customer is using OMAP3530.  At a bare minimum I could really use some approximation within an order of magnitude, i.e. are we talking 100s of milliseconds, seconds, 10s of seconds?

Hi Brad,

We are talking on an order of 100s of milliseconds.

Just to be clear, can the software be modified/upgraded to support more or does some other hardware factor such as the amount of RAM preclude this?

This is a limitation in the WL1271 Firmware/ROM and cannot be upgraded to support more than 5 Stations.

Hi Brad,

It's a limit which takes into consideration some HW limitations, yes.
It can't be upgraded easily by just updating the SW.
