Cell Phone Spying and Encryption
Higher quality picture - Digital conversion takes out the “noise” from the signal.
Less bandwidth – digital data is compressed which allows for more “white space” for other data.
Compatibility with other digital devices--tv’s are now designed for digital/computer compatibility.
Digital TV – Why go digital?
With analog signals shut down, US and other countries are forced to get a converter box for analog (rabbit ear) TVs.

Interconnected VoIP providers must transmit all 911 calls, as well as a callback number and the caller’s registered physical location, to the appropriate emergency services call center or local emergency authority.
