3G EVDO
What is EVDO?
EVDO, also known as EV-DO, 1xEvDO and 1xEV-DO, is an ideal for high speed radio broadband. The acronym is abruptly 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 flag is known as W-CDMA. The major EVDO preparations in the US are by Verizon and Sprint, and there is also a large network in Korea. At present, EVDO has not made substantial affect in Europe or other major Asian markets; W-CDMA is the 3G standard of choice in those regions.
This saves bandwidth for use by other devices; when incomplete party on a phone call is talking, the connection consumes no bandwidth because there are no packets to send. Or, when an internet web site is accessed, no bandwidth is used till the site starts sending the web page. EVDO instead adopts the same approach used for the internet. IP, the Internet Protocol, breaks data into small pieces called packets.
