NT EVDO – Wireless Broadband Internet in Nepal

EVDO device connected on laptopTelecommunication must be the only field in Nepal which is the most developed in developmental infrastructure. Following March 2, 2010 (Falgun 18, 2066), Nepal Telecom is going to launch another internet service in Nepal- this is NT-EVDO Wireless Broadband Internet Service as a part of CDMA WIRELESS Telephone Service of Nepal Telecom. EVDO (Evolution Data Optimized) is a third generation (3G) telecommunication standards/protocol, also called as cdma2000 1xEvDO. With this there is going to be wireless broadband internet access to majority of people.

As the name suggest EV-DO only supports data (DO- Data Only), there is no voice/phone call service , the  service which supports voice as well like is EVDV ie Data cum Voice. This service is much more expensive than traditional data services at the expense of higher data transmission rate.

Technical Side of 3G Wireless System:

1xDV: 3G extension of IS-95B, shared data and voice
1xDO: 3G extension of IS-95B, data only
1xEV: 3G extension of IS-95B, data with circuit-switched voice
1xRTT: 3G extension of IS-95, one RF channel only

The cdma2000 1xEV (DO and DV) is the wireless data technology with channel bandwidth of 1.25MHz on FDD (duplexing) which require software and digital card upgrade on 1xRTT networks on the infrastructure side. However, this does not require new spectrum – meaning government assigned older/used frequency spectrum can be used. The requirement for new handset is important but not compulsory. New handsets will work on 1xEV at 2.4 Mbps, 1xRTT at 144 Kbps, IS-95B at 64 Kbps. Older handsets can work in 1xEV but at lower speeds.

Nepal Telecom’s EV-DO is featured with downlink air interface speeds of up to 2.4 Mbps and uplink speed of up to 153 Kbps. (Telecom says interface speed in Rev A is up to 3.1 Mbps and 1.8 Mbps respectively)

What is EVDO exactly and what can I do in EVDO?

EVDO, a 3G system evolved from CDMA IS-95,  is a relatively newer telecommunications standard for the wireless transmission of data and voice signals through radio signals, typically for broadband Internet access. It uses multiplexing techniques including code division multiple access (CDMA) as well as time division multiple access (TDMA) to maximize both individual user’s throughput and the overall system throughput.

EVDO is a perfect choice for broadband solution on the move. For frequent travelers (inside the valley), EVDO provides packet data services to achieve high speed, high capacity and excellent portability. It lets you move seamlessly from cell to cell, creating a true mobile wireless broadband internet experience at any time or place, including real-time video streaming, large volume data downloads and web browsing.

How can I get NT EVDO Wireless Broadband Internet in Nepal?

Nepal Telecom has started this service as the extension of the present CDMA (IS-95) system. The service is enabled in the EVDO R-UIM provided by NT and it can be used in various devices like USB EVDO modem, PCMCIA EVDO modem, EVDO mobile, etc. EVDO devices can be used as a modem to achieve higher data bandwidth in user’s portable device like laptop or fixed desktop computers.
