I was reading a cable television trade publication, Multichannel News,
and I come across an adverti***t that descibes how cable systems
can utilize unused channel capacity to offer PCS services.

What are the frequencies used by this system?
Can these signals be intercepted?

It would depend on the cable company as to what frequencies are used.
PCS is digital.  Its very difficult to intercept.

Wrong again. PCS is digital but on a copper line it is easy to intercept.
Ever here of an
IFR??

If it's so easy then why hasn't digital cable been hacked yet?

I said it was difficult, not impossible.  The cops in this town have gone to a
digital radio system just to prevent nosey ears from listening in.

The same ones used for PCS!!!

Quote:> Can these signals be intercepted?  

Sure! As well as you can intercept any PCS signal. Tune to
1.9GHz...But you probably can't do much with it!

All they are doing is using the CATV "trunk" as a link to connect
the little cell-sites with the central office.

*Something* has to carry the traffic from the remote cell site to
the main switching office. That "something" is usually leased
land lines or microwave radio.

Modern CATV systems are two-way - Signals in the field can be
sent back to the head-end. Ever wonder how the cable company gets
the city council meetings from across town? The two-way
capability is the heart of high speed "cable modems".

What they are doing is placing tiny PCS "cell sites" along the
cable TV trunk cable, and using the CATV trunk as a "conduit" to
carry the traffic back to the switching office (and also provide
power). No land-lines or microwaves needed - and since they are
already up on poles - no expensive towers needed.

If there is a "hole" in the cell companies coverage - they can
slap one of these low-power sites on the nearest CATV trunk to
fill in the "hole" - without having to dump tens-of-thousands of
dollars into setting up a conventional cell site, obtaining
permits, finding a site, etc, etc.

Simply, the mini PCS "cell sites" work like any other cell site,
but they receive their datastream on an unused TV channel and
send their data on the sub-bands. By using the existing CATV
wiring and poles, the PCS company saves having to install cell
towers.

Pretty neat idea, really...

Paul Grohe

you can use IFRs, NOHAUs, etc..      there is equipment available from HP,
Rhodes and Schwartz...
Do you want a training course???!!!!!

Not true there have been hundreds of post of people wishing to
descramble digital tv. You are just the only one stupid enough to say
you can hack it... Now everyone can write you for the hack you don't
have.

******   ATTENTION EVERYONE   ***********************************

This guy has a hack for digital cable tv.. I am sure if you e-mail him
he will tell you how to do it....

I said intercept. Complete hacking is another story. I can intercept and
descramble...but it would cost you over
$100,000. to do so. We have the Equipment here to do so, but it has many
applications besides CATV theft.!!!!! You said
it was impossible. I said "NOT TRUE"!!!
