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
