Mass-produced modems in the United States began as part of the SAGE air-defense system in the year the word modem was first used [2] , connecting terminals at various airbases, radar sites, and command-and-control centers to the SAGE director centers scattered around the United States and Canada.

The rapid update of modems led to a similar rapid increase in BBS use, which was helped by the fact that BBSs could control the modem simply by sending strings, rather than talking to a device driver that was different mpdem every direct-connect modem. Wireless modems can be embedded inside a laptop or appliance, or be external to it. Wireless ac,ink come in a variety of types, bandwidths, and speeds. Please help improve this article by adding citations to reliable sources.

Echo cancellation eliminated this problem. The next major advance in modems was the Hayes Smartmodemintroduced in Once the connection is completed, they send their signals into the phone lines as normal, but also into the delay, which is inverted. They transmit information that is modulated onto a carrier frequency to allow many simultaneous wireless communication links to work simultaneously on different frequencies.

Many other standards were also introduced for special purposes, commonly using a high-speed channel for receiving, and a lower-speed channel for sending.

When more flexible solutions were needed, third party ” dialers ” were used to automate calling, normally using a separate serial port to communicate with the dialer, which would then control the modem through a private electrical connection. This is accomplished through hardware flow control using alink lines on the modem—computer connection.

A USB modem used for mobile broadband Internet is also sometimes referred to as a dongle. This package supports the following driver models: It was similar in design, but used the lower frequency set for transmission.

Error correcting avlinkwhich encode code words sets of bits in such a way that they are far from each other, so that in case of error they are still closest to the original word and not confused with another can be thought of as analogous to sphere packing or packing pennies on a surface: This was why earlier modems split the signal frequencies into “answer” and “originate”; the modem could then ignore any signals in the frequency range it was using for transmission.

One typical example was used in the French Minitel system, in which the user’s terminals spent the majority of their time receiving information. A single additional channel in the reverse direction allowed the two modems to communicate how much data was waiting at either end of the link, and the modems could change direction on the fly.

The drawback of this approach is a loss in quality, which causes image content to mldem pixelated and smeared. Using a modem also allows for frequency-division multiple access to be used, making full-duplex digital communication with many users possible using a single wire.
