Wireless IR System to support multiple rooms

I am installing a HDMI distribution system that will feed 4 rooms (over Cat5). I would like to be able to use a remote in any of those rooms to control the source device. does anyone know of an IR wireless system that can handle 4 receivers in each of the rooms to 1 transmitter? I have thought about just buying 4 wireless sets figuring they all work on the same frequency and just chuck the extra transmitters.

What exactly is the "source device"?

Would it be possible to use a Bluetooth remote instead?

The IR wireless transmitters you're talking about most likely each have a unique code, so they only work in pairs.

However, with some creativity, you could probably tack all 4 transmitters to the same device.

You could use Logitech Harmony RF remote system with "IR mini blasters" for each device.

There are also several smartphone apps which use "bluetooth to IR repeaters" but they are shorter range.

The Harmony's all have to be paired between remote an receiver, so you would need a separate RF receiver set for the remote in each room.
But you could use their Smart Control, which puts a box at the source than can be controlled from any cell phone/tablet on the network.

You won't be happy with wireless based IR, I did this for two customers who's houses were not wired correctly, both complained there is too much lag after pressing a button on the remote. Also they complained the batteries don't last very long on the remotes. The unit I used was this: »www.amazon.com/Next-Generation-R···00C1Z0HA

I would suggest you distribute the IR over the HDMI link, examples...

I was vaguely familiar with CEC protocol but extending IR is an unusual but useful application.

Wireless IR extenders could use simpler protocol and non-ISM frequency (like 433Mhz or DECT) to improve performance.
