Internet Connectivity using Mobile Technologies (3G, GPRS, CDMA)

Motivation

These different technologies use the infrastructure of mobile telephone networks. Recently there has been a boom in the development of these technologies as exemplified by the following facts:

  • Tanzania: The deployment of the 3G network by Vodacom, deployment of CDMA 800 networks by TTCL and Zantel, deployment of CDMA 450 network by BOL. Excerpted from [1]
  • India: This is the only option for users in rural areas where no other means of broadband Internet are available. GPRS Enabled Cell Phone costs around $10 p.m., Charge about $0.025 per megabyte. Vendors: Hutch/Airtel/Reliance Excerpted from [2]
  • Beijing: 6-month plan costs RMB650 and an annual plan that includes a high-end GPRS modem costs RMB2400, which can work anywhere in China. Excerpted from [3]
  • Finland: GPRS will be suitable option in the rural areas for offering the Internet connectivity in the near future. Excerpted from [4]

How to connect XO to Internet using Franklin CDU-680DOrA Mobile Broadband USB Modem

The following steps are needed to have this modem working with XO:

1. Insert the modem into any USB slot on XO. The device will be shown as a removable storage. 2. Copy the following files to a directory on XO. Here [5] you will find the necessary components that include:

  • Packages

1. Wvdial : wvdial-1.54.0-5.2.2.1.i386.rpm 2. PPP: ppp-2.4.4-2.i386.rpm 3. Libwvstreams: libwvstreams-4.2.2-3.fc7.i386.rpm

[2] and [3] are the dependencies for installing [1].

  • Files

connect, itfchg, cdu680config, execute.sh, run.sh

These are needed for installing the drivers for this particular modem.

3. Run the run.sh script so that the device is recognized as a modem.

4. You can test that ppp0 is added as an interface by writing route -n command on the Linux console.

5. If it is there, you can start using Internet on XO!
