IEEE 802.15 and IEEE 802.16 standards are for metropolitan
systems using wireless access.

Complete specifications are available to the public for download
at no charge.

The colloquial term "Wi-Fi" is for wired systems using other IEEE
802 standards.

The point is do something cheaper than the satellite. Anything really
intended to work a block away probably wouldn't be.

One of the higher decimal number IEEE 802 Standards is for up
to 30 miles range. That might be a "Texas block" to some, but
most cities aren't 30 miles across. :-)

I have some of those 802 Standards but I'm not going to bother
with looking up any details for the regulars in here. Those (nearly
all PCTAs) will just tell me to go to the ARRL website for "a good
read." :-)

If you want the link to free IEEE 802 standards downloads, send
me e-mail.
