agreed - you will always have those legacy issues, good thing for
backwards compatibility. But its not like we are just get accustomed to
WLAN now. The expectations are higher. g rolled out much quicker than
b and n will roll out much quicker than g.

Good point, though those legacy client devices seem to stick around
longer than you think. In any case, shipping chipsets will be
predominately 802.11n by 2009 and my guess is that the installed base of
clients will reach 50% that year.
I think Kevin's 5 to 8 years is much too conservative.

Actually, all but the lowest end of client devices are already shipping
with n. With that said, assuming a conservative 4 year refresh cycle,
in just 2 years the simple majority of the clients will be n and in 4
years the overwhelming majority will be n. Besides, with MIMO you will
see better performance from your legacy abg clients so the move to n aps
has mutiple drivers/benefits.

We are currently rolling out Cisco a/b/g wireless and asked the vendor
about designing with 802.11n in mind. The overall response was that the
technology is too immature and any predictions would be highly
speculative. They also said that the consumer base would not be
populated with N - capable devices within the next 5-8 years in
sufficient numbers to realize an advantage.
So what does the population think about the lifespan of the current
802.11a/b/g technology?
