By contrast, a cordless telephone is used only within the short range of a single, private base station. In addition to telephony, modern mobile phones also support a wide variety of other services such as text essaying, MS, email, Internet access, short-range wireless communications (infrared, Bluetooth), business applications, gaming and photography. Mobile phones that offer these and more general computing capabilities are referred to as smoothness.
Landlines phones:A landlines telephone (also known as land line, land-line, main line, homophone, landlines, fixed-line, and hireling) refers to a phone which uses a solid medium telephone line such as a metal wire or fiber optic cable for transmission as distinguished from a mobile cellular line which uses radio waves or transmission.
SMS / Text Messaging: Short Message Service (SMS) is a text messaging service component of phone, web, or mobile communication systems. It uses standardized communications protocols to allow fixed line or mobile phone devices to exchange short text messages.
The term “SMS” is used for all types of short text messaging and the user activity itself in many parts of the world.
SMS is also employed in direct marketing, known as SMS marketing. SMS as used on modern handsets originated from radio telegraphy in radio memo pagers using standardized phone protocols. These were defined in 1 985 as part of the Global System for Mobile Communications (GSM) series of standards as a means of sending messages of up to 160 characters to and from GSM mobile handsets.
Though most SMS messages are mobile-to-mobile text messages, support for the service has expanded to include other mobile technologies, such as ANSI CDMA networks and Digital AMPS, as well as satellite and landlines networks. Fax Machines: Fax (short for facsimile), sometimes called telescoping or telltale, is the telephonic transmission of scanned printed material (both text and mages), normally to a telephone number connected to a printer or other output device.
The original document is scanned with a fax machine (or a telescopic), which processes the contents (text or images) as a single fixed graphic image, converting it into a bitmap, and then transmitting it through the telephone system. The receiving fax machine reconverts the coded image, printing a paper copy. For many decades before digital technology became widespread the scanned data was transmitted as analog. Pagers: A pager is a wireless telecommunications device that receives and splays numeric or text messages, or receives and announces voice messages.
One-way pagers can only receive messages, while response pagers and two-way pagers can also acknowledge, reply to, and originate messages using an internal transmitter. [l] Pagers operate as part of a paging system which includes one or more fixed transmitters (or in the case of response pagers and two-way pagers, one or more base stations), as well as a number of pagers carried by mobile users. These systems can range from a restaurant system with a single low- power transmitter, to a nationwide system with thousands of high-power base taxation.
POI (voice over IP) phones: A Poi phone or IP Phone uses voice over IP (Poi) technologies for placing and transmitting telephone calls over an IP network, such as the Internet, instead of the traditional public switched telephone network (EST.). Digital IP-based telephone service uses control protocols such as the Session Initiation Protocol (SIP), Skinny Client Control Protocol (SCUP) or various other proprietary protocols. Keep / Face time: Keep is a free-MIM voice-over-IP service and instant messaging client developed by the Microsoft Keep Division. The name originally rived from “sky” and “peer”.
The service allows users to communicate with peers by voice using a microphone, video by using a WebMD, and instant messaging over the Internet. Phone calls may be placed to recipients on the traditional telephone networks. Calls to other users within the Keep service are free of charge, while calls to landlines telephones and mobile phones are charged via a debit-based user account system. Keep has also become popular for its additional features, including file transfer, and videoconferencing. Competitors include SIP and H. 323-based services, such as Linchpin and Google Voice.
