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 station, for connection to one wireless appliance at a time, with complete connectivity
through to outside GGSN’s. (A GGSN provides the gateway between the GPRS network and the
public packet data network, also known as the Internet). This means you can quickly and easily
connect a wireless device to your choice of real Internet websites through a simple LAN
connection to the Internet.
You can also perform protocol logging 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 tutorial uses a WAP (Wireless Application Protocol) browser built into the phone to show
how IP datagrams can be transmitted and received. Data will be exchanged using WML
(Wireless Markup Language), which is derived from HTML for wireless device use. Using the
phone’s WAP browser, you will connect to a WAP Proxy Gateway program running in your PC.
The WAP Gateway program will “pass through” the Internet addresses that you enter into the
phone’s browser, and will act as a go-between the phone and the Internet.
This tutorial uses the WAPlite Proxy Gateway.
To run the Infinite WAPlite Proxy Gateway software on your PC:
1. On your PC choose Start…Programs.
2. Choose the “WAPLite” directory
3. Select “WAPLite”. A window will appear with multiple tabs.
4. In the WAPLite window, select the “Options” tab
a. If your LAN DOES NOT use a firewall to access the Internet:
i. Check the box next to “Use HTTP Proxy Server”
ii. Other boxes on this tab should NOT be checked
iii. Type the name of a valid proxy server in the box next to “HTTP Proxy
Server” (You may find the name of your proxy server in Internet Explorer
Tools menu. Select Internet Options…Connections…LAN
settings…Proxy server. You should also consult your local IT department
for this information.)
iv. At the bottom of the tab, if the word “Apply” is in black letters, click the
“Apply” box (if grayed out, skip this step).
b. If your LAN DOES NOT use a firewall to access the Internet:
i. All boxes on this tab should NOT be checked, including “Use HTTP
Proxy Server”
ii. At the bottom of the tab, if the word “Apply” is in black letters, click the
“Apply” box (if in gray letters, skip this step).
5. On the “Stats” tab, click on “Install Service” to turn on the WAP Gateway software in
your PC.
With the WAPLite software running on your PC, external devices (like a phone) can
access this gateway server via the PC LAN port. The WAPLite server has one set of
