X-Telecom-Digest: Volume 12, Issue 372, Message 5 of 9
I am happy to announce that Qualcomm has released most of the text of
the CAI (Common Air Interface) for its CDMA (Code Division Multiple
Access) digital cellular technology, as recently submitted to the TIA
TR45.5 standards committee evaluating wideband spread spectrum digital
cellular telephone technologies.
It can be retrieved by anonymous FTP from lorien.qualcomm.com
(126.96.36.199) in the directory /pub/cdma.
Due to copyright considerations, chapters 2-5 of the CAI are not yet
available for FTP. They deal only with the analog FM mode used for
backward compatibility with existing cellular systems and as such
contain material previously copyrighted by TIA. If or when we receive
permission to release these chapters, we will.
The /pub/cdma directory contains the following files:
announce - this file (ascii text)
copyright - copyright notice (ascii text - please read)
FrontMatter.ps.Z - Table of Contents, compressed Postscript
Chapt1.ps.Z - Chapter 1, " "
AppendA.ps.Z - Appendices
The RSA MD-5 message digests for these files, as computed on a Sun
Sparcstation, are as follows:
As Qualcomm's connection to the Internet is a 56kb/s link, we
encourage other sites with faster connections to also make these files
available so we can minimize the load on our connection.

Subject: CDMA Overview Document Available by Anonymous FTP
Organization: Qualcomm, Inc
X-Telecom-Digest: Volume 12, Issue 457, Message 4 of 9
A new CDMA document is now available by anonymous FTP from
lorien.qualcomm.com. The title is "An Overview of the Application of
Code Division Multiple Access (CDMA) to Digital Cellular Systems and
Personal Cellular Networks". The file name is /pub/cdma/Overview.ps.Z
and is in compressed Postscript format.
The 64-page document provides a comprehensive technical overview of
the basic design principles behind Qualcomm's CDMA system. Some of the
material was originally in our internal version of the CAI, but being
tutorial in nature it was removed from the official version released
to the TIA standards process. Considerable new material has also been
added to reflect actual results from the field tests in San Diego.
When logging into lorien.qualcomm.com, use "anonymous" as your user
name, and give your actual name as the password. Be sure to specify
image (binary) mode when retrieving this file. You will need the UNIX
"uncompress" command (or equivalent) and a Postscript printer or
interpreter to print or display this document.
As before, we encourage other sites to pick up this document and make
it available to others by anonymous FTP to help limit the load on
Qualcomm's 56k connection to the Internet.
