(Sysops Note: None of this material COMPILED by Raven appears to be his own
work! After examining some other files on cellular phreaking, I discovered
some of the primary sources of his material are several articles written by
The Mad Phone Man, an article on IMTS by The Researcher (of this bbs (P-80),
and numerous other sources. Raven would suggest that this is his knowledge.
One example of this a question and answer segment that Mad Phone Man had in
one of his cell phreaking series. Raven has substituted his name where the
answers are similar to a type writtin copy of a conversation, whereby the
person speaking at the moments name is at the beginning of that line or lines.
Thus it appears that Raven would like us to beleive him knowledgable on this
subject. NOT! He has also removed all original credits of the real authors.
Sounds like another teenager on an ego/power trip. However, even though some
of this material is duplicated on this system, some is not, so im gonna run it.
I do hope the technical data survived his COMPILING of this data better than
his spelling and use of the english language. Scan Man)
Hmmm.... Another text file.. Make sure that you keep this one for your
collection!! There is no other text file that is more complete or up-to
date that explains cellular phone phreaking like this one for 1992!!!
Since this is going to be a complete manual it has been broken-up into
2 parts so this is manual 1. I'm hoping that there will be some info.
on cellular phreaking published in PHRACK that may be able to help you and
me with our endevors but I'm waiting.
Another thing that I just found out is that the Hack/Phreak Community is
in need for a BBS that doesn't give bullshit info (most do!) and thats cause
our world has been infiltrated with narcs and telco/bell agents that try to
spread as much misinformation as possible!! But there are a few bbs's that
keep the faith and they will be listed at the end of this text.

CELLULAR PHREAKER TYPES
-----------------------
There are two types of cellular phone phreakers. The first type is the one
whos's intrested in scanning cellular phone channels basically to overhear
conversations. The second type is the one who obtains and modifies cellular
equipment so that he can make free phone calls at someone elese's expense.
I. IMPROVED MOBILE TELEPHONE SERVICE
This system that was used prior to cellular phones was the Improved Mobile
Telephone Service (IMTS), which was much easier to scan for.
Most scanner enthusiasts are familiar with this standard mobile phone
system; this system has gone thru little evolution in the past decade in the
U.S. It has remained a considerably limited service. A large metro area may
only have several hundred users, (New York City has about 900 mobile phone
subscribers) dur largely to limitations imposed by spectral overcroeding.
Land mobile commo has seen a 10-12% annual growth rate for the past two
decades. The result is that the 40, 150 and 450 MHZ bands are overcrowded.
Even the utilization of the new 900 MHZ band (with 30-40 times more channels
available than other bands) is a short-lived solution to the problem.

The VHF high-band freqs. are the most popular IMTS channels. If you live
within 25-50 miles of even a moderate sized town, you should have at least
one VHF high-band channel. VHF low-band IMTS is used in rural areas and
those with hilly terrain. UHF IMTS is primarily used in cities where the
VHF channels are crowded. If you live in a major city, expect to have most,
if not all, of these channels available to you.
II. GENERAL CELLULAR INFO
This section is a little boring but it's needed to set a basic foundation
of cellular phone phreaking so that part 2 doesn't sound like all
technicial talk!
The FCC originally estaablished 3 cellular bands. One was given to the local
Bell or Telco, (wireline carrier), one to an independent firm (non-wireline
carrier), and one reserved for future use. Originally there were 666 cellular
freqs or channels. In recent years the FCC has tacked on another 156 freqs
for a total of 832 freqs, and all cellular makers have upgraded their phones
to accomodate the new channels. Some of the new channels appears above the
original 666 while others appear below.
The cellular system cannot know whether or not a cellular phone can be
switched to one of the 156 channels without the phone telling it. This is done
by the Station Class Mark (SCM), which is a 4-bit binary number.
(1) Bit #1 is "0" for 666 and "1" for 832
(2) Bit #2 is "0" for a mobile unit and
"1" for a voice activated
