Maximum number of CC3000 per Wifi Access Point

Post by pdp8e »

I would like to use the CC3000 as an alternative to an Xbee module. Power is not an issue, as it will not be battery powered.

I have Xbee modules and the the most it can handle is about 60 packets per second, before it starts to drop data. ( the data size is 10 bytes, using API protocol)

That is with no encryption and from the end device to the coordinator.

I want to monitor many devices, around 100 to 200, and have them connect to an access point ( gateway, to pass the data onto a server via Ethernet)

Is the limitation the access point? Very hard to find information on the number of clients that can connect to an access point. Does anyone know which wifi gateways can handle this?

Hope any one can help.

Thanks in advance,
Manuel

The limitation would be the access point. There's no logical reason why an AP couldn't handle 200 clients. If it becomes a problem in practice, however, you could always use two or more access points.

Actually, multiple access points should work better anyway, as there will be less contention for each channel - meaning fewer collisions and dropped packets.

Thanks for your reply.

Do you know of any access points that can provide that capacity?

Are the current CC3000 libraries at a point where it could be used for this?

Over 90% of the traffic would be from the cc3000 to the access point, then passed on to the server.

On occasions the server will need to get back to the cc3000.

Thanks again.

As I said, there's no reason why any access point shouldn't be able to do that. I don't know of any specific examples. You could look for the kind they use in h.otels and public hotspots.

Even more reason to use multiple access points instead of a single one.
