The GSM1800 basestation in San Francisco is part of Orange's R&D centre, which they opened in 2005 (see:
http://www.orangepartner.com/site/en...er_centres.jsp). The exact location (500 m away from the Hampton Inn) is:
Orange Labs
801 Gateway Blvd, Suite 500
South San Francisco,
CA 94080, USA
Btw in Germany, where we've only GSM900 and GSM1800, there's a GSM1900 basestation from Cingular at the USAF airbase in Ramstein.
