    If it is a strong enough laser, you can just make it scan (a simple mirror attached to a small motor will do it). You'll create a light triangular plane, instead of a light line.

    By staying at the side of the runway, and pointing your light 'wall' to the plane, you'll greatly enhance your chances that the pilot's window will cross the laser beam, and that the pilot's eye will be hit. A high-speed vibrating mirror with an adjustable vibration angle will further enhance your odds (you can have it crossing the window hit area more times per second).

    We currently use Office 2k.

    Because some partners and clients who are still using Office 95/97 (and even 2k itself) sometimes couldn't open our Office files, we now only send stuff in pdf (automatic conversion through a linux virtual shared printer and ps2pdf).

    Then the only thing that forces us to have Office is that sometimes we RECEIVE stuff in those formats.

    I'm thinking about this:
    - Have one single license of Office 2k (or XP, for that matters) on a windows server on the network,
    - setup VB/VBA programs/macros to automagically open any file it sees in such and such directories (shares) and both print them to the "pdf" printer (saving the original formatting) and saving them to a KOffice / StarOffice compatible Office older version (allowing edits).

    Has anyone already done this? Would it be LEGAL? (I was about to setup Acrobat Writer in the windows server to create the pdfs, when I found out it was not legal, so I switched to gs)

    I believe "printing" to pdf would be straightforward and easy from VB. What about saving? How would I open a file (disallowing its own - untrusty - macros to run) and then run a pre-defined macro which is not in the file itself?

    GSM is a digital communications standard that is not limited to frequencys.

    Correct. Just allow me to fix and add some other data:

    US uses:
    824MHz - 894MHz for "Cellular" (824-849MHz Phone->BaseStation, 869-894MHz BaseStation->Phone), using AMPS (analog), TDMA/IS136(or ANSI-136) and CDMA/IS95 (digital), with some IS136 operators testing GSM 800.

    806MHz - 866MHz for "SMR" - iDEN/Nextel (806-821MHz Ph->BS, 851-866 BS->Ph)

    1850-1990MHz for "PCS" (1850-1910MHz Ph->BS, 1930-1990MHz BS->Ph), using CDMA, TDMA/IS136, and GSM (GSM was up and running in Europe when PCS appeared in the US. I know that "GSM standard is part of the PCS standard" was not exactly what you meant, but...)

    Europe (and others) use:
    880-960MHz (880-915MHz, 925-960MHz), and 1710-1880MHz (1710-1785MHz, 1805-1880MHz) for GSM.

    Europe was a mess of different systems, and they've cleverly converged to GSM. The USA once had mostly AMPS, then diverged to a mess of different systems. Clever.

    GSM was the result of a planned evolution; a list of desired features drove the engineering, and it always offered more features to the user than the American digital standards, which were likely driven by a "let's do something digital quick, before someone does it and get the market". Example: for many years IS95 and IS136 had NO FAX/DATA capabilities, while GSM had 9600 (this was fast, one day).

    The number of GSM subscribers in Europe alone is much bigger than the number of all technologies subscribers (analog and digital) in all America (South, Central and North, including the USA ;)).

    Although GSM 1900 require more BaseStations than Cellular 800 due to less propagation of higher frequencies, it is not true for GSM 800 or GSM 900, coverage-wise.

    GSM does have less conversations per MHz of freq.band than IS136 and IS95 (that may not be true if using half-rate channels, with lower audio quality), but the GSM infrastructure is normally cheaper than the ones for IS136 and IS95 (because in a way, GSM Base Stations are dummier than the IS136/IS95 ones), so operators can deploy more GSM sites than IS136/IS95 with the same money.

    True, CDMA is the future, and a technologically superior solution (bear in mind that IS95 is CDMA, but CDMA is NOT IS95). Even GSM will probably migrate to a CDMA solution in the future (***CDMA is not IS95***).

    GSM is a "open system" standard (ok, unless you want to design all the chips and algorithms from scratch, you DO have to pay royalties to someone if you manufacture a GSM phone or Base Station using them)

    If you want to download the GSM standards (or part of it - it's probably about 10,000 pages by now), you can do it for free at etsi.

    If you want to have or use the IS95 standards you have to pay (eia/tia). Although the IS95 (AKA CDMAone) standard is open (for ~360USD), the technology is Qualcomm proprietary.

    By the way, Brazil had followed USA on the 800MHz band (we're mainly IS136 and IS95, few hard-headed AMPS users left), but our "PCS" will be GSM 1800 (European frequency). I have no complains about my IS136 phone or operator, but I'll be the first in line when they start selling GSM 1800 (like I was, for IS136).
