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 [5] to /home/olpc/ folder on XO using
cp -r cdmamodem.zip /home/olpc
3. Unzip it using
unzip cdmamodem.zip
4. Run modemXO script using
bash modemXO or ./modemXO or bash /home/olpc/modemXO
Please Note: Necessary Packages will be installed by the script modemXO. 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
5. Using command
route -n
You can test that ppp0 is added as an interface. If it is there, you can start using Internet on XO!
