Dual Band 'N'

[Dolby]

How does it work if it runs at 2.4ghz/5ghz simultaneously and the device does the same - considering 5ghz doesn't travel as far as 2.4ghz?

Is it 5ghz when close enough and as you move further away and signal drops, it automatically goes to 2.4ghz?
Or is 1 packet sent on each frequency as and when needed?

If it's proper, simultaneous dual-band, then you have 2 wireless networks basically. Some devices can connect on 2.4 GHz, others on 5. The 2 networks can have different SSID's, passwords, etc. It's like having 2 separate routers combined into one.

If it's the other, El Cheapo dual band, it just means you have to decide which band to use and set the router for that.

If you connect to both networks at the same time, it probably picks the
fastest one based on signal strength, altgough I might be wrong...

It doesn't automatically switch. You have two SSIDs in wireless networks e.g mynetworkG and mynetworkN. Both are seperate networks.
Dual band just mean one device can connect to your router using 5Ghz(N) and another device can connect to 2.4Ghz(G) at the same time.

Yea - that was actually what I was looking for.
I'll keep Googling ... thanks though!

The way I understand it is like TJ99 explained :

You get a dual band with true simultaneous and then the cheaper ones which you have to select either 2.4 or 5. So a device that supports both bands will automatically switch if it's a more expensive unit?

I'll check though

I have a dual band router.

A single band router means that it can only support one band at a time in its settings. In the settings you have the option either use 802.11G or 802.11N. A 802.11G wireless stick won't work (unless you are right in front of the router) if the network is set to 802.11N mode. Same goes for the other way round.

Dual band means one device can connect to your router using 5Ghz(N) and another device can connect to 2.4Ghz(G) at the same time.

Example of single band router:Netgear DGN2200
Example of dual band router:Netgear DGN3300

Switching between networks is possible but not on the router itself the OS will handle that. MS windows does not switch unless disconnected and only supports one active wireless network connection

Proper dual band devices, the ones claiming 450Mbps, can aggregate channels from both 2.4 & 5 on a single connection. Problem is there are few clients with that capability e.g. standalone 450Mbps PCIe cards or the very latest high-end laptops with integral Centrino Ultimate-N 6300 adapter.
