Packet Data Service Example Procedure (via Simple IP)

Last updated: August 31, 2009

This section is only applicable to the lab application.

The following procedure is an example of how to use the test set for IP packet data transfer over simple IP protocol. For example procedure using mobile IP protocol, see Packet Data Service Example Procedure (via Mobile IP) .

This procedure is to demonstrate how to access the test set's built-in web server via the RF interface over packet data service from a laptop computer (PC). A cdma2000 mobile station used as a wireless modem will be connected to the USB port on the PC running USB port software developed by the manufacturer of the mobile station.

The purpose of this procedure is to serve as an overview of the tasks required for a typical data channel application. If your particular application involves accessing internet or intranet sites via the test set's LAN interface, additional requirements such as getting through corporate firewalls may complicate setup procedures.

A. PC Setup

Install and Configure Device Driver

Install the USB and modem drivers provided by the wireless modem manufacturer. Connect the USB port from the wireless modem to the PC. When run for the first time, the software prompts the user for setup information. When properly configured, the PC will recognize the wireless modem on the USB (or other) port.

Configure the PC for a dial-up connection to the Internet via the wireless modem

The laptop has to be configured to include the wireless modem in its list of networks. The network dial-up connection properties must be configured according to the requirements of the wireless modem and the data port driver. When the PC is properly configured, the "Network and Dial-up Connections menu" should include the wireless modem in its list of connections.

In this example, on the PC running the Windows 2000, select the Network and Dialup Connections from the Control Panel. Select Local Area Connection icon, right click, and select Disable. Then select the Make New Connection icon, set up an internet connection with the new added modem (the connection is named as "Wireless Modem", for example).

B. Hardware Connections

There are many different configurations for testing wireless modems (or other wireless appliances such as WAP enabled mobile stations) data handling performance. See HTTP Functional Test for a diagram of the configuration used for this example.

Note that if the test set has LAN 2 PORT , the LAN port, the LAN 2 Port and the server should all be connected to a hub. In this example (access the test set's built-in web server via the RF interface over packet data service from a laptop computer (PC)), you should just connect the LAN port with the LAN 2 port using a LAN cable.

RF (Wireless Modem to Test Set)

Connect the wireless modem RF cable to the test set's RF In/Out port.

PC to Wireless Modem

For this example, the USB port provides the connection. Connect the USB port from the wireless modem to the PC.

C. Test Set Setup

Press the SYSTEM CONFIG key.
Press the Instrument Setup ( F1 ) key, set up test set's LAN settings (see A. Configure instrument information and setup. ). For example,
- Set LAN IP Address to 130.29.181.1
- Set Subnet Mask to 255.255.0.0
- Set Default Gateway to be blank (enter a 0 to make it blank)
- Set LAN IP Address 2 (Data+) to 130.29.181.90 (Note that the LAN IP Address 2 (Data+) must be set properly if the test set has the LAN 2 Port.)
- Press F6 (Close Menu ).
Press the Call Setup key to go to the Call Setup screen on the test set.
Press the Radio Config ( F11 ) key and select the radio configuration, for example, (Fwd3, Rvs3) , in which you would like to bring up the call.
Press the FCH Service Option Setup ( F12 ) key, select SO33 (+F-SCH) in the Service Option for Fwd3, Rvs3 for this example.
You may need to set some parameters that are required for your mobile station to find service. For example, Cell Band, Channel, SID, etc. See How Do I Set Up an IS-2000 Call? .
Press the left More key to go to Call Control 3 of 3 menu.
Press the Data Channel Info ( F2 ) key.
Press the Data Channel Parameters ( F1 ) key. See How Do I Set Up Data Channel Parameters? .

In this example the network consists of only two IP addresses, the PC and the Test Set. The DUT IP Address will be sent to the PC if you set the Internet Protocol (TCP/IP) Properties to "Obtain an IP address automatically" menu. You should set the DUT IP Address and the test set's IP address (set in step 2) unique and in the same subnet (see IP Address Requirements ). For example,
- Set F-SCH Data Rate to 153.6 kbps
- Set DUT IP Address to 130.29.181.2
- Set the External PDSN State to Off (Indicating simple IP service). For mobile IP settings, see Packet Data Service Example Procedure (via Mobile IP) ).
- Press F6 (Close Menu ).
To improve the data transfer speed, we recommend you set the Cell 1 F-SCH Level to -7 dB on the Code Channel Parameters menu (see How Do I Change Generator Information? ).
Now, the test set setup are ready for a dial-up connection from the PC.

D. Functional Test

In order to test the functioning of the wireless modem, it must first complete a dial-up connection between the test set and the PC.

Turn the wireless modem on and wait for a power-up registration. The mobile station information should appear in the Mobile Reported Information window after a successful registration. Otherwise, you may need to change some settings appropriate for your mobile station to find service. For example, Cell Band, Channel, SID, etc. See How Do I Set Up an IS-2000 Call? .
On the PC (for example, Windows 2000), select Start, Settings, and Control Panel. In the Control Panel window double click Network and Dial-up Connections.
Double click the icon labeled with "Wireless Modem" which is set up during the procedure (see Configure the PC for a dial-up connection to the Internet via the wireless modem )
In the Dial-up Connection window, select the Dial button.
Verify that a connection is active by looking for Connected + Data shown in the Active Cell field on the bottom center portion of the test set's screen. Now, you are ready for the demonstration to continue.
Open the browser on the PC (for example, Internet Explorer). Enter the IP address of the test set in the PC browser Address window (in this example, http://130.29.181.1). The PC browser should display the test set's internal web server page:
As data is transferred, monitor the Counters window (see Data Counters ). and the Data Throughput Monitor window (see Data Throughput Monitor ). These tools are useful for analyzing data transfer rates under various RF and call processing conditions.
You can also use the Wireless Protocol Advisor (WPA) to log cdma2000 control and stack messages, PPP (Point-to-Point Protocol) packets, RLP frames, and IP (Internet Protocol) packets for analysis of the data channel. See Protocol Logging .
