This way, authors and contributors share information about their
progress.
Community messages include target dates and
deadlines for publication of new editions,
addition of new chapters or topics,
major new contributions, file check-in
check-out, major changes of directory
structure.
Access is open to anyone who indicates
an interest in publishing on the wireless
communication CD-ROM. See
wireless.per.nl for details.
... Send
us a photograph of a cellular base station in your part of the world.
| If you are a hobby photographer and enjoy seeing your photographs on this CD ROM, why not send us your picture. Remember, this is a multimedia presentation and we are interested in much more than textual contributions only. We would like to include your photographs of antenna installations, measurement set-ups, circuit boards, chip designs, products, etc.

audio or video contributions, etc.
Please choose file names that adhere to the
DOS 8.3 character format, except for Java &trad; animations.
Do not use uppercase in any filename.
Please use the same four characters for all files that belong together. Please appropriately use subdirectories audio, video, images slides, postscrp and software.
This helps to keep the file structure of the CD ROM manageble.

files. We have had very positive feedback from matlab code included on the
CD-ROM. It allows other researchers to elaborate on your work, thus use your
work as a reference. Further, good research means that other can verify what
you have been calculating. Just a curve of a BER doesn't say anything unless
you explain the assumptions and model. Even better, also allow other to see
the model being translated into math and software code.

Material will be reviewed, similar to the review process for a journal papers, but with a special focus on reference and educational values.
As a special project, a revision and extension of the glossary is welcome.
Particularly, we would like to have translations into foreign languages, including a pronounciation example as audio file. Preferred languages are Chinese, French, German, Japanese, Korean, Russian, Spanisch.
