EVDO is short for Evolution-Data Optimized or Evolution-Data Only. It is the new emerging standard for wireless data transmission via radio signals. This technology is currently used for wireless broadband Internet access. In the constantly advancing telecommunication technology, EVDO has come up using multiplexing techniques like CDMA or Code Division Multiple Access and TDMA or Time Division Multiple Access to improve and maximize the performance of the individual user and the overall system. EVDO travels on the CDMA network, just like cell phones.

This 3G wireless broadband Internet access service called EVDO is in direct competition with Wi-Fi. While Wi-Fi has limitations, EVDO transcends most of this and provides always-on Internet services. Wherever your cell phone has range, EVDO will work and provide high-speed Internet. The US has seen a rise in EVDO service providers with the emergence of Verizon and Sprint as the leading contenders. In India, state-owned communications giant BSNL has already gone ahead and rolled out EVDO wireless broadband services in selected Indian cities and towns. With EV-DV, EVDO’s voice counterpart slated to arrive, the wireless Internet service scene looks bright.

Broadband Internet services in India have recently come of age. But rapid advances in this area belie India’s late entry into the field. Various public and private service providers already compete with each other and the fierce competition has already seen price cut wars. With EVDO being adopted by public and private players, the competition is heating up. Tata Indicom, one of the largest private players, has already introduced the USB Internet modem based on the CDMA platform. Tata Indicom was earlier eclipsed by Reliance Infocomm, another big private player in its rush to launch the internet data card or usb-CDMA modem. Now the BSNL has entered the scene with a fancy launch of the EVDO data card.

Whether it’s DSL broadband or EVDO wireless broadband or WiFi, customers will enjoy surfing the web at breakneck speeds at virtually rock-bottom prices.
