I'm not going to disagree with you, Lee, on anything related to fuller-featured silicon and powering. My only point of disagreement would be with compatibility -- I think what the vendors are offering now will work with the final standard with minimal or no compatibility issues.
I believe people will later make some apple and oranges comparisons because the final-standard based silicon will have more capabilities (things that are optional in the spec now) and so there will be some confusion in regards to that, but nothing in regards to compatibility.

Yikes, Frank- you're painting one expensive "work around" scenario for big WLANs- especially when "better silicon is right around the corner"... why not just wait for better silicon? (Not being contentious- just not yet getting the payoff of jumping in now but not leveraging what you're buying on hardware you underpower and that can't be guaranteed to stay compatible). Seems like even if you wait a year, you're still going to be a pre-standard early adopter who has better hardware to choose from- by all the expectations expressed pretty much everywhere that I'm seeing. -----Original Message----- From: Frank Bulk [mailto:[EMAIL PROTECTED] Sent: Thu 1/17/2008 3:59 PM To: [email protected] Subject: Re: [WIRELESS-LAN] The Aesthetics of 11n? Are you suggesting a dongle that plugs into two Ethernet ports on a Cisco switch that transports the Ethernet and power over different pairs to the Aironet 1250? I'm pretty sure that Cisco will/would not do this. They're in business of selling switches, too, so they are more likely to point customers this fall (my guess) to 802.3at-capable switches, while in the meantime point out their support for the 1250 with their 3750E and newer 4500 and 6500 blades. Newer chipsets and designs will use less power, something I see Cisco using in a 1100-like device that is likely to come out within the next 12 to 18 months. Combine that with turning down the power, using less TX/RX antennas, using a 20 instead of 40 MHz-wide carrier and 802.11b/g instead of 802.11n at the 2.4 GHz range, I think people will find a compromise that works for them in the short term. Fall 2009, I don't think as many compromises will need to be made because people will have some 802.3at gear, but more likely, enterprise WLAN vendors will have 2nd-generation gear that can work without compromise within 802.3af specifications.

I'll restate my concern with Cisco 802.11n wireless strategy: Hopefully it's not too late for Cisco to reconsider providing an the option to bond two 802.3af ports to get dual radio capable 802.3at power at the switch... I can't think of any large existing POE deployed site that would consider going from a well managed POE environment to unmanaged injectors. I know that's the "official line" at this point but it doesn't make sense. And, forcing an large switch (or blade) upgrade on customers will make possibly make these customers look elsewhere for a centralized/controlled-based wireless platform that *can* use the existing 802.3af POE infrastructure... Good news for non-Cisco vendors (which seem to be very present on this list!) People generally look at a whole picture when doing large upgrades.
