General Comments
Over time, testing cellular phones on voice calls has become very consistent and reliable.
Customers expect and rely on repeatable, consistent performance from cellular phones.
This applies to both “real” customers who use phones in real networks, and to Agilent
customers who use our test equipment to verify phone performance.
However, data transmission over cellular phones is a different story (at least at this time:
around May 2003). Using a phone as a wireless modem can be very frustrating, because the
behavior is sometimes not repeatable and inconsistent when connecting and making data
calls. From my experience, this applies to commonly available phones from multiple
vendors, and in multiple technologies: GSM, GPRS, cdma2000, W-CDMA.
When you hook a phone up to a PC, it takes on some of the characteristics of a PC that most
people know well. So, when you use this demo guide, do not be surprised if you must reboot
your PC and your phone multiple times to get a demo to work. If a phone seems to have
stopped responding, it is probably the phone equivalent of Microsoft Window’s “blue screen
of death”.
