802.11n Access Points and Power over Ethernet: Key Considerations
Want to implement IEEE 802.11n but concerned over the power demand?
As we have noted before, IEEE 802.1n is the only wireless-LAN (WLAN) technology that matters today. The outstanding improvements in rate, range, and price/ performance now being seen in both residential/SOHO-class as well as enterpriseclass products, as demonstrated by our own testing, have previously led us to conclude that the time to install .11n is now and that waiting will only result in an investment in last year’s technology.
Truly conservative technology adopters will of course take comfort in delaying action until the ink is dry on the still-under-development IEEE 802.11n standard, but the evergrowing demand for network throughput and capacity, as well as the need to support greater time-bounded traffic, indicates to us that .11n is today a far better investment than the venerable .11g and .11a. And the existence of a widely-implemented interim .11n specification from the Wi-Fi Alliance simply drops the last real barrier to adoption.
We sincerely doubt that the official standard will differ in any meaningful way from this spec, and, if it does, backwards compatibility is all but assured.
