Upgrading Wi-Fi — What, When, and Why
I don't expect a lot from wireless. It's sort of like plugging a wonky network cable into a hub. You're connected to the network, but everything is delivered at 'best effort' or worse. Most of the time, that's really all that you need.
Can I open a web page? Check.
Send an email? Check.
VNC into a box? With some patience, check.
SSH into a device? Check.
Can I do 95% of what I do at work over a wireless connection? Check.
The other five percent? I'm hoping for Gig-E because I'm using all of it.
The key is having realistic expectations of wireless. If your users don't understand that then they'll probably be disappointed with whatever you rollout.
