Fixed–mobile convergence

Fixed–mobile convergence (FMC) is a change in telecommunications that removes differences between fixed and mobile networks.'Fixed Mobile Convergence is a transition point in the telecommunications industry that will finally remove the distinctions between fixed and mobile networks, providing a superior experience to customers by creating seamless services using a combination of fixed broadband and local access wireless technologies to meet their needs in homes, offices, other buildings and on the go.''Seamless is defined as there being no perceptible break in voice or data transmission due to handover (from the calling party or the called party's perspective)'.'Extension to Cellular technology: software seamlessly bridges office phone services to mobile devices, permitting the use of just one phone number and one voice mailbox. Client software extends the capabilities of the PBX to a mobile smartphone, creating a virtual desk extension. This software runs on Nokia Series 60 phones and works in conjunction with Extension to Cellular.' Fixed–mobile convergence (FMC) is a change in telecommunications that removes differences between fixed and mobile networks. In the 2004 press release announcing its formation, the Fixed-Mobile Convergence Alliance (FMCA) said: In this definition 'fixed broadband' means a connection to the Internet, such as DSL, cable or T1. 'Local access wireless' means Wi-Fi or something like it. BT's initial FMC service, BT Fusion used Bluetooth rather than Wi-Fi for the local access wireless. The advent of picocells and femtocells means that local access wireless can be cellular radio technology. The term 'seamless services' in the quotation above is ambiguous. When talking about FMC, the word 'seamless' usually refers to 'seamless handover', which means that a call in progress can move from the mobile (cellular) network to the fixed network on the same phone without interruption, as described in one of the FMCA specification documents:
