What is EVDO?
EVDO is an acronym for “Evolution Data Only” or “Evolution Data Optimized” which is a standard for high speed wireless networks used for Broadband Internet connectivity. EVDO enables computer users to have high speed Internet access without the help of a hotspot. Just by inserting an EVDO card into the computer, users get connected to the Internet within seconds and have Net access at DSL-compatible speeds.
EVDO, also known as EV-DO, 1xEvDO and 1xEV-DO, is a standard for high speed wireless broadband. The acronym is short for “Evolution, Data Only” or “Evolution, Data Optimized”. The official name, defined by the Telecommunication Industry Association, is “CDMA2000, High Rate Packet Data Air Interface”. It is one of two major Third Generation, or 3G, wireless standards. The competing standard is known as W-CDMA. 3G is designed to provide voice and high-speed mobile data using the cellular approach already proven to work in mobile phone networks. The biggest obstacle to implementing high speed wireless networks is the lack of bandwidth, or range of usable frequencies. Just as only so many radio stations can be squeezed onto the FM dial, only so much data can be transmitted across the available bandwidth. EVDO is an advanced CDMA technology developed by Qualcomm to deal with this limitation. CDMA, Code Division Multiple Access, uses advanced mathematical techniques to allow multiple wireles
Just the Basics: • EV-DO – Evolution Data Optimized • Personal broadband wireless service for a wide range of customers, from business people to students • Always on – – similar to DSL (wherever DO capability is available) • Rides on CDMA signal- 1x data capability available everywhere CDMA voice service available • Up to 10 times the peak data rate of the next best public wireless solution – 500 to 1,000 Kbps average(kilobits per second), comparable to DSL speeds • Allows the user to be connected herever they are are not only for email, but for downloads, large files, photos, spreadsheets, etc. • Advantages over WiFi: • Always on with seamless roaming! • Signal can travel on same cell sites as cell phones • No 300-ft range from the cell tower or “hotspot” • Customers can access their corporate VPN (virtual private network) anywhere they can get a cellular signal via a secure, encrypted signal • Can download and run video clips in real time • Can provide service to customers outside of
