Good analsys of public wifi: Two clues for vendors:
1) It costs nothing to provide WiFi. If that’s not true, you’re doing
it wrong. The billing infrastructure is probably 90% of Starbucks’
cost. So loosen up on access, don’t freak out if somebody finds a
hole that gives them free access, and focus on keeping costs down.
2) If users can’t log in and get going in a hurry, your WiFi is
useless. You can’t charge a premium *and* provide bad service, and
since charging a premium means that you have lock down the system
so tightly that it takes a while to log in, don’t do either. Thanks Gary for the pointer.
