VoIP (Voiceover Internet Protocol)

Voice over Internet Protocol (VoIP) is any of a family of methodologies, communication protocols, and transmission technologies for delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. Other terms frequently encountered and often used synonymously with VoIP are IP telephony, Internet telephony, voice over broadband (VoBB), broadband telephony, and broadband phone.

Broadband & ADSL Cable

Broadband

The term broadband refers to a telecommunications signal of greater bandwidth, in some sense, than another standard or usual signal (and the broader the band, the greater the capacity for traffic). Different criteria for broad have been applied in different contexts and at different times. Its origin is in radio systems engineering, but became popularized after MediaOne adopted it as part of a marketing campaign in 1996 to sell their high speed data access. The slogan was "This is Broadband. This is the Way". The term has never been formally defined, even though it is used widely and has been the subject of many policy debates, and the FCC National Broadband Plan.

ADSL Cable

Asymmetric Digital Subscriber Line (ADSL) is one form of the Digital Subscriber Line technology, a data communications technology that enables faster data transmission over copper telephone lines than a conventional voiceband modem can provide. It does this by utilizing frequencies that are not used by a voice telephone call.

Bluetooth

Bluetooth is an open wireless technology standard for exchanging data over a short distance (using short wavelength radio transmissions) from fixed and mobile devices, creating personal area networks (PANs) with high levels of security. Created by telecoms vendor Ericsson in 1994, it was originally conceived as a wireless alternative RS-232 data cables. It can connect several devices, overcoming problems of synchronisation.
