Is the AP following the controller communication speed?

[GaeMi]

When installing a Cisco 2504 Wireless Controller and a 1850 Wireless AP, can the wireless AP not communicate beyond 1 Gbps?

What do you mean? You are limited by the port on the AP which you would never cap out.

[GaeMi]

The data sheet for the wireless controller 2504 states that it supports up to 1 Gbps.

In contrast, the 1850 AP's data sheet states that the 5Ghz band supports up to 1.7Gbps.

If so, is the communication speed limited to 1 Gbps when a client communicates wirelessly?

You are confusing yourself on hardware throughout and wireless throughput.

Simple, the WLC has 1gig ports, but you can lag all four to give up up to 4gig. The ap has a 1gig port, but some AP’s support lag which you need two Ethernet cables which can give you 2gig. Some of the newer AP’s support mGig which gives you 1, 2.5 and maybe 5gig support.

Now throughput from a wireless client is different as wireless is half duplex. If your device shows you are connected at 600mbps, your Mac theoretical throughput in a good RF environment would be half of that. The more clients connected on the same channel, the throughput goes down. You can search the internet and research this topic. Wireless and wired are different... half duplex vs full duplex.

Hope this gives you a better understanding.
