Tetrad of the telephone

TELEPHONE TETRAD

ENHANCEMENT Mobile phones today have continually enhanced wired and cellular phones since the first cellular phone public customers in Chicago in 1977.	OBSOLESCENCE Alexander Graham Bell's success with the telephone came as a direct result of his attempts to improve the telegraph. Mobile cellular phones have since made landline wired phones obsolete.
RETRIEVAL Retrieves previous inventions of communication such as the wired phone and early cellular phones as well as means and access to internet information using desktop and laptop computers.	REVERSAL Reverts to previous means of communication and information access via the Internet.

Today, we have an abundance and variety of cellular mobile communication devices. The telegraph, operating since the 1840s, and the early telephone were both wire-based electrical systems (http://inventors.about.com/od/bstartinventors/a/telephone.htm). It was long ago that individuals began experimenting with wireless telephones. In 1865, Dr. Loomis was one of the first to communicate with another through the atmosphere (http://cellphones.org/cell-phone-history.html). Dr. Cooper designed and used the first cellular phone in 1973 and in 1977; the Chicago community were the first public customers of the cellular phone. Since this time, the cellular telephones have changed and diffused rapidly around the globe. In the 1990s, 2G digital networks were online and replaced analog network frequencies making them obsolete (http://www.tech-faq.com/history-of-cell-phones.html). Soon after, 3G mobile phones arrived and included SMS text, email, and Wi-Fi Internet access.

Mobile phones today are capable of instant communication and information access with increasing miniaturization, speed, and quality. Today we have smart phones, touch phones and more. We can take photos and video and instantly send them to others around the globe or post them to the internet. We can have face to face calls and instantly send a text message. We can download and read books on our phones and play games on the internet with that same device. We can watch television on our phones.

Over the past few years, the cellular phones have continually been improved with changes to retrieved information from earlier devices. Mobile cellular capabilities and use may revert to earlier communication and information access through wired systems such as landline telephones and wired computers. It may even revert back to older forms of communication such as good old letter writing and face to face meetings. Reasons for this reversal could include: newly recognized health risks due to mobile device use, newly discovered environmental risks to due to mobile devices, or a realization of some cultures that mobile devices have destroyed the benefits of our earlier social interactions, pace of life, and personal values.
