View Full Version : Wireless - Single vs dual radio

What are the benefits of dual radio access points over a single?
I'm looking at a situation where there are 20 to 30 users on one or two access points in a wireless network. There will be a mix of wireless cards.

If it is the same ones as I am thinking, dual radio ones mean you can run both G and N networks at full speed;
G on the 2.4GHz band and N on the 5GHz band.

The advantage is that you get better speed (if you have both N and G traffic sharing the same 2.4GHz band, it slows both down). But they cost more than normal ones.

So dual radio doesn't really provide any load balancing of wireless devices on the same channel.
It is more about diff cards being able to run at full speed.

well in a sense it does offer load balancing; for home users for example, they can put all their normal traffic on the 2.4GHz G network (eg web browsing etc) and all their high speed things like file transfers, media streaming etc on the 5GHz N network.

But I dont think they do load balancing on the same channel, I haven't investigated that. It is possible though, eg 2 radios, both on 2.4ghz, but one is for G and the other for N. It will depend on the router itself.
