Did you get permission to use that WiFi link from the house next door?
If not, you're breaking privacy laws, and they could sue you. You fall
into the same category as a hacker.
See, this is one of the small sticking points that none of the 'WiFi
can be used for broadcast' clowns latch on to.
What defines that WiFi is not relevant for broadcast is:
1. WiFi access points are *private*. Its not a free for all.
2. WiFi access points are unicast. Nearly all vendor AP hardware is
configured to squelch UDP traffic in favor of TCP traffic of any sort.
3. There is no TV on the internet.
4. You cannot roam transparently without service interruption between
APs.
5. IF you increase the service radius of a wifi network, your clients
won't be able to connect back to it if they are out of their own
operating range.
The model is about as different from a television broadcast station
model as you can get. Just because they both use RF doesn't make them
equal in any way. But then again when I listen to some of the people
spouting nonsense when comparing the two, its easy to conclude that
they don't know what the heck they are talking about anyway.
Just because someone broadcasts their SSID, doesn't give you any rights
at all to use their link - even to the point of just grabbing a DHCP IP
address.
WiFi APs might be littered all over the place, but almost all of those
are not for free public use. So its a moot point, really.
So my response to Powell's comment would be - what are you smoking, and
where can I get some of that?
BTW In a keynote speech at the PBS Tech Conference, APTS suggested we
change the name 'DTV' to 'WiFiTV', since WiFi is the 'in thing'. How
does one even begin to address such a comment? Mind boggling.
