BANGALORE, INDIA: The high-speed EVDO (Evolution Data Optimized) data cards launched by Bharat Sanchar Nigam Limited (BSNL), Bangalore Telecom District, a year ago, is finding more takers with 4,000 plus customers in the city. EVDO-based data services on CDMA are available in the city covering most of the areas. It has up to 10 times the peak data rate of the next best public wireless solution - 400 to 1,000 Kbps average and allows the user to be "connected" wherever they are - not only for email, but for downloads, large files, photos and spreadsheets.
In order to further popularize the use of EV-DO data cards, BSNL is offering EVDO (USB-type data card) as a bundled solution along with the Type II broadband plan on copper. This plan comes with a discount of Rs. 250 with unlimited usage on EVDO. The requirement is you should have a monthly broadband or combo plan of > Rs. 499.
With both wired and wireless connectivity, the user can have a unique combination of backup and mobility. With speeds technically up to 2.4 mb, EVDO cards are set to make a huge impact, a senior BSNL official said.
However, depending upon the traffic density, when you are the move, you get up to 1.8 Mbps speed, he added.
"Presently, EVDO gives you mobility within Bangalore city, and in case you have a broadband connection at home, the EVDO also works as a backup," the official said.
Today, EVDO also has a second application which is enterprise-centric. In addition to offering high speed connectivity, EVDO offers a link back-up to banks. BSNL has tested the same with over 10 banks. Bangalore Telecom is the first one in BSNL to test this application with banks in the country. "BSNL is planning to extend the same all over the country," he added.
"Even the security aspect of this technology is critically tested with these banks. This system supports any organisation having multiprotocol label switching (MPLS) connectivity."
Features of EVDO: * EVDO/1x is based on CDMA and is deployed in most parts of the country. * In CDMA, the signal is much lower than the noise. The signal to noise ratio is less than 1.
