>If your argument is that Wi-Fi by itself can not supplant broadcasting=20
fine. I agree.=20
The subject like on the thread answers that one.
>wireless technology and connections to fiber nodes then yes Wi-Fi can=20
be part of a wireless system that can supplant current one way TV/DTV=20
broadcasting as regulated by the FCC as full power broadcasters to fixed =
receivers.
At the edge you have WiFi boxes, all unicast based, and all unable to =
handle
more than a hundred or so users per node. Throw the easy ability to jam =
the
access points with a cordless phone and the fact that this is truly a
hacker's dream (much packets to sniff and RSTs to send) and you have a
disaster waiting to happen.
You need nextgen WiFi standards and boxes to make this a success. Anyone
doing it now is doing it for fun. Anyone doing it commercially (for
broadcast replacement) is surely either na=EFve, insane, or careless.
>The multiGbps meshnet MAN will be GigE wireless. It obviously is GigE I =
don't see why you say it isn't. Such a network for backhaul eliminates=20
That=92s to the backbone. Users don't connect to the backbone - period =
end of
story - so this point is completely moot. You're still constrained by =
the
small pipes at the edge. Your backbone could be 10GigE for all we care - =
it
would make no difference.
A GigE wireless AP costs $25-35k. There are no consumer versions. Nice =
try
though.
>I expect content providers to be attracted more and more to this new =
way=20
to reach their customers bypassing all current gatekeepers. One way OTA=20
broadcasting will be limited to mobile and portable reception. The fact=20
that it can be received fixed also will be incidental.
Waving of hands.=20
Where can I buy a WiFi STB with service? How many content companies =
(people
with real content, not fly-by-nites) do you know that distribute all =
their
content on the internet vs. satellite DTH? Howcome almost all the WiFi =
APs
out there have such crappy backplanes that they can't even carry =
multicast
traffic at low bitrates without falling over, or squelching other =
sessions?
Name a fully redundant mesh that covers 50k people and provides full =
bitrate
to all 50k people (I chose 50k for a conservative viewer base compared =
to
OTA). The list goes on.
Maybe in 5 years this will start to happen and things will mature (and
attract content delivery folks) - but for right now, you're pipe =
dreaming.
I have some Streaming Media conference tickets to sell you...
