Unreferenced date August 2008 Image PCI V.92 Fax Modem Card Digon3.jpg thumb right A V.92 fax modem card A fax modem enables a computer to transmit and receive documents as fax es. A fax modem is like a data modem but is designed to transmit and receive documents to and from a fax machine or another fax modem. Some, but not all, fax modems do double duty as data modems. As with other modem s, fax modems can be internal or external. Internal fax modems are often called fax boards. History In the early 90 s small business PCs commonly had a PC based fax modem card and fax software typically WinFax Pro . Now largely replaced by E mail, PC based faxing with a fax modem is more and more a rarity. Where faxing from a PC is required there are a number of Internet fax Internet based faxing alternatives. So, while it s still common to see businesses with a one or more traditional fax machines churning out pages, they are often surrounded by a forest of PCs processing even more E mail. PC faxing Computer users may set up a PC fax modem with card, telephone line access and software, or use a service similar to printing from a PC or sending an E mail message. Fax integration is available in unified communications e.g. E mail, Voice Mail and Fax managed together , in a number of Business telephone system Hosted PBX systems Hosted PBX products where standard features allow users to send a fax by using the fax phone number as the address of a E mail message, and receive incoming faxes via E mail with the Fax content presented as a PDF attachment. The use of fax modem cards after the 1990s became a last resort, as compared to a high speed Internet connection. Few users saw a reason for the effort of making this old technology approach work.

Image Teleplay large.jpg thumb 200px right The Teleplay Modem attached to a NES and a Sega Genesis. The Teleplay Modem was a modem for the Nintendo Entertainment System created by Keith Rupp and Nolan Bushnell , designed to provide online play between NES users, while also possessing compatibility with the Sega Genesis and Super Nintendo Entertainment System Super Nintendo . The first prototype, called the Ayota Modem , had a maximum speed of only 300 bit s, too slow to render normal NES quality graphics. It was unveiled at the 1992 consumer electronics show in Las Vegas, where it received a fairly good reception. Bushnell later dropped out of the project, and Keith Rupp founded the company Baton Technologies . He continued to develop the modem, changing its name to the Teleplay Modem, increasing the speed to 2400 bit s, and also conceiving the idea of Sega Genesis and Super Nintendo system compatibility. The modem would also allow cross platform play between Nintendo and Sega with properly coded games. Three games were developed internally Battle Storm, Terran Wars, and Sea Battle but never released. Both Nintendo and Sega refused to license the Teleplay Modem or the games developed for it. Sega instead licensed AT&T to develop a modem the Edge 16 , but no hardware was ever sold at retail. The venture capitalists behind Baton Technologies feared competing against AT&T and attempting to sell hardware games without the all important licensing, so Baton was unable to fulfill its first 300,000 order, and quickly folded thereafter in the summer of 1993. Later Catapult Entertainment developed the 2400 baud XBand modem, similar to the Teleplay Modem in many respects. Although well funded by Old Viacom Viacom , Catapult failed to receive sufficient developer and gamer backing, folding in early 1997.

ITU V.21 V.21 Capable of only 300 bit s, it is an international standard used mainly outside of the U.S. V.22 Capable of 1200 bit s at 600 baud. Used mainly outside the U.S. V.22bis Used in the U.S. and out, it is capable of 2400 bit s at 600 baud. V.23 Used mainly in Europe, it allows the modem to send and receive data at the same time at 75 and 1200 bit s. V.29 A one way half duplex standard that is used mostly for fax machines. Capable of 9600 bit s. V.32 A full duplex standard capable of 9600 bit s at 2400 baud. V.32 modems automatically adjust their transmission speeds based on the quality of the lines. V.32bis A second version of V.32, it is capable of 14,400 bit s. It will also fallback onto V.32 if the phone line is impaired. V.32ter The third version of V.32, capable of 19,200 bit s. V.34 Capable of 28,000 bit s or fallback to 24,000 and 19,200 bit s. This standard is backwards compatible with V.32 and V.32bis. V.34bis Capable of 33,600 bit s or fallback to 31,200 bit s. V.42 Same transfer rate as V.34 but is more reliable because of error correction. V.42bis A data compression protocol that can enable modems to achieve a data transfer rate of 34,000 bit s. V.44 Allows for compression of Web pages at the ISP end and decompression by the V.44 compliant modem, so transmitting the same information requires fewer data packets.

Unreferenced date April 2009 Radio modems transfer data wirelessly across a range of up to tens of kilometres. Using radio modems is a modern way to create Private Radio Networks PRN . Private radio networks are used in industrial critical applications, when real time data communication is needed. Also Radio Data Modem enables user to be independent of telecommunication or satellite network operators. In most cases users use licensed frequencies either in UHF or VHF band. Licensed frequency is reserved for given user in certain area thus ensuring that there is less likelihood to have radio interference from other RF transmitters . Also licence free frequencies are available in most countries, enabling easy implementation, but at the same time other users may use same frequency, thus making it possible that given frequency is blocked. Typical users for Radio Data Modems are Surveying Land survey differential GPS , fleet management applications, SCADA applications utility distribution networks , automated meter reading AMR , telemetry applications and many more. Since applications usually require high reliability of data transfer and very high uptime, radio performance plays a key role. Factors influencing radio performance are Antenna radio antenna height and type, the Sensitivity electronics sensitivity of the radio, the output power of the radio and the complete system design.
