Simultaneous dualband (2,4GHz and 5GHz), 40MHz, 400ns in Wireless Charts

[DaveMcLain]

What Tim has said is very simple: A router with dual radios can produce a connection that's 300Mbs in each band and that can happen simultaneously. BUT while this would give a total throughput of 600Mbs TWO or more clients would have to be used to achieve this setup. One machine operating in the 2.4Ghz band and the other one operating in the 5Ghz band. Would it be possible to bond both bands together and serve one client with all of this bandwidth? I don't know is that possible? Either way this is not the same as the N technology that has not emerged yet which supports four spatial streams for 600Mbs. When that happens will a dual band AP support 1200Mbs and 8 streams?


4 stream N is still in the future:

This would be similar to calling an 8 port gigabit switch a switch capable of 8-Gigabits links. You might be able to hook your one computer to all 8 ports and bond them somehow, but people normally do not do this.

Similarly, there are two radios in those routers, but you'd only connect to one radio. As far as I know, there aren't any cards that connect to both bands at the same time. Also, I think that client cards only have one radio, so you can use two streams but only on one band at a time.
