Dave, it was 1986 they started Qualcomm with a view to creating cdma, which they had been thinking about probably for 3 years before that when they were working in Linkabit creating TDMA. They did a lot of the work which invented TDMA! They sold out to go on to the cdma world. They have had thousands of people working on cdma and how many hundred patents issued. I was hoping you and Clark would get together - being both intellectual property experts. Go ahead, knock yourselves out; we are hanging on every word. We want to know that Qualcomm has got patent rights for multimedia cdma for mobile phones buttoned down. Meanwhile, some figures from "Global Wireless" May-June 1998 Volume 1, number 3, so it is a bit out of date, but near enough.globalwirelessnews.com But I got the figures from the paper edition, page 8. United States: Annualized Wireless Industry Data Date....total............cell sites.......annual.......local..... ........subscribers.......................service $.....bill $..... 1997....55.3m...........51600......27.5bn......42.78...... 1996....44.0m...........30045......23.6bn......47.70...... 1995....33.8m...........22663......19.1bn......51.00...... 1994....24.1m...........17920......14.2bn......56.21...... 1993....16.0m...........12805......10.9bn......61.48...... 1992....11.0m...........10307........7.8bn......68.68...... 1991......7.6m.............7847........5.7bn......72.74...... 1990......5.3m.............5616........4.6bn......80.90...... 1989......3.5m.............4169........3.3bn......89.30...... 1988......2.1m.............3209........2.0bn......98.02...... 1987......1.2m.............2305........1.2bn......96.83...... cdmaOne network construction only began in late 1996 and continued during 1997 and is still continuing at a high rate. The other figures are for analog, GSM and TDMA. As you can see, there is a rapid increase in subscribers. The 34m who were signed up in 1995 are using oldish handsets, most of which will be analog. Coverage remains an issue, but cheap calls must be tempting a lot of people to swing over to cdmaOne. 1998 figures will be fun. Mqurice
