3.6 Product feature:
Data channel
This is one of the most useful and
powerful features of the E6701A.
The test set acts as a GPRS base sta-
tion, for connection to one wireless
appliance at a time, with complete
connectivity through to outside
GGSN’s. (A GGSN provides the gate-
way between the GPRS network and
the public packet data network such
as the Internet). This means you can
quickly and easily connect a wire-
less device to your choice of real
Internet Web sites through a simple
LAN connection to the Internet.
You can also perform protocol log-
ging during data channel operation,
and even though IP data is usually
discontinuous, the E6701A allows
you to make TX and RX parametric
measurements during data channel
operation.
This demonstration uses a WAP
browser built into the phone to
show how IP datagrams can be
transmitted and received. Data will
be exchanged using WML, which is
derived from HTML for wireless
device use.
Using the phone’s WAP browser, you
will connect to a WAP proxy gate-
way program running in your PC.
The WAP gateway program will
“pass through” the Internet address-
es that you enter into the phone’s
browser, and will act as a go-between
for data between the phone and the
Internet.

With the WAPLite software running
on your PC, external devices, such

WAPLite server has one set of local
“test” data (a logo and some text)
provided with the software that can
be accessed by an external WAP
browser.
