I have repeatedly asked Apple to submit the product for review and they have not.
I echo the "too bad" sentiments expressed earlier. I was going to submit a post asking about the possibility of a review myself until I saw this thread had already been started.
Aside from the basic "how well does it work?" questions, I saw something else in the product announcement articles that seemed very interesting.
"Inside Apple’s AirPort Extreme, Time Capsule updates" by Glenn Fleishman, Macworld.comNormally, Wi-Fi devices choose somewhat arbitrarily which base station they connect to when multiple base stations share the same network name for roaming purposes. Wi-Fi adapters typically try to get the best connection, such as that with the best signal strength, but standard Wi-Fi doesn’t offer better choices.
Apple senior product manager Jai Chulani, who focuses on the company’s Wi-Fi line, said that Apple had modified that for its hardware. He explained that an algorithm looks at the signal strength and also the available network speed to determine which band’s network to join.
I use a D-Link DIR-655 (Rev A4) and have absolutely no experience with a simultaneous dual band router. More than that though, I'm more than a little "hazy" on exactly what advantages simultaneous 2.4 & 5GHz is supposed to provide.
I believe one (the only??) advantage is that if you have a mixed protocol environment you could split things and run the 802.11n devices by themselves in the 5GHz band. But again, exactly how one does that escapes me. I have assumed you'd assign different SSIDs to the 2.4GHz and 5GHz bands and separate the traffic by selecting the 5GHz SSID for the "n" clients and the 2.4GHz SSID for the others.
It sounds like Apple is claiming that with their latest Airport Extreme you wouldn't have to bother with such details. You could have just one SSID for both bands and the Airport would automagically and dynamically select the "best" band for each client.
If that
is what Apple is implying, it would be nice to have someone with an inquiring mind run some pertinent tests to see how well it actually works. Heck, I'd be happy even with some impertinent testing ...
Oh, well. Maybe you could keep asking them for a review copy, say once a month or so?
