Hey, have you guys heard of wimax? I heard a blurb about it on the news this morning and did a little reading about it.
Instead of a wireless range of only a couple hundred feet, it is supposed to increase that range up to about 30 miles.

And the encryption is supposed to be much better

to avoid what happened with 802.11." The WiMAX specification mandates AES-CCM encryption between CPEs and base stations, along with key management based on X.509 digital certificates, RSA public-key encryption algorithm [PKCS #1].

Couple other introductory pages:

Sounds good. I wonder how it will play out in the real world?
