1.4.2 1x
1x provides a digital cellular telephony system and can provide wireless Internet
access at speeds between 60 and 80 kbps, with bursts up to 144 kbps.
1.4.3 Security
1x and EV-DO data transmissions are highly secure. Originally developed based
upon the "spread spectrum" pioneered by the US Department of Defense,
security in CDMA technologies is obtained by spreading the digital information
contained in a particular signal of interest over multiple coded paths, over a much
greater bandwidth than the original signal.
