Routers: Simultaneous dual band vrs concurrent?

[sswilson]

In the past, simultaneous dual band (wireless N) routers have come with a fairly hefty price, but just today I came across a netgear product at Costco (not on the website, and I unfortunately didn't jot down the model number) which claims to be able to run both wireless N and 2.4G connections concurrently but was priced at a reasonable $45 (vice the $120 that the linksys "simultaneous" router was priced at). While I couldn't find the trendnet online, they did list an ASUS which also uses the "concurrent" wording rather than simultaneous. ( Costco - ASUS® Concurrent Dual Band Wireless N Gigabit Router= )

Anybody else come across this yet? Is it just a change in the wording of the marketing, or is there a difference that I'm not aware of?

edit:

Hrmmmm.... looks like it was this one.... TRENDnet | Products | 300Mbps Wireless Dual Band Routers | TEW-671BR .... maybe it's so cheap because it's only 10/100?

Bingo.

I have that RT-56U model, and it can transmit both frequencies simultanously.
