The Coming Time for 802.11a?

abhikhurana writes " This article on 80211-planet.com predicts a real boom in the market for 802.11a in the coming year. An excerpt from the article: In tests in my SOHO LAN, I found that in real world conditions, 802.11a averaged four times faster than 802.11b. In addition, with its 5GHz frequency, 802.11a avoids the interference slow-downs that b must suffer with microwave ovens, high-end wireless phones, and other 802.11b networks. Also makes an interesting read for knowing about the technologies which maybe driving the wireless bandwagon in the coming years."

802.11b is good enough

[joshv]

I think we have reached the 'good enough' point with wireless networking. 802.11b is faster than any internet connection I will have in the forseeable future, and performs perfectly well for the small day to day file transfers over the LAN. It doesn't work for large file transfers, but when I need to do those, I pull out the Wi-Fi card, walk the laptop over to the hub, and plug a spare cable into it's ethernet port.

I won't be upgrading until there is a compelling reason, and I can't see there being one for at least the next 3-5 years.

And how long....

Until the 5 GHz band becomes just as crowded as 2.4?

802.11a is not the wave of the future. It's going to be a nice for those hardcore who absolutely need obscene speed and live in an interference-prone environment.

It has to compete against the HUGE installed base of 11b hardware that is *far cheaper* than 11a and is more than adequate for 90% of the people out there.

I was thinking of upgrading to 11a since I happen to be a power user - But that means that the card I bought would be useless on most networks I might roam to (such as my former college's wireless network). In the end, 11b won out because:
a) I already had some 11b equipment
b) My parents had 11b equipment
c) I have never had problems with 11b interference - Spread spectrum is pretty resistant to CW interference (Microwave ovens - People could run microwaves all they want in my apartment and I wouldn't notice any difference on my network.) and 900 MHz analog is "good enough" for me in the cordless phone arena, which means that the most famous 802.11b interference culprit (2.4 GHz phones) isn't present.
d) 11b hardware was a helluva lot cheaper than 11a hardware.
