The act of transferring a mobile from one voice channel to another, providing constant seamless communications when moving. Used when the quality of the original voice channel reduces and another channel can be found to provide a better link. The handoff can be between cells, or between sectors. The handoff command is sent over the FVC to the mobile and contains the new channel number, MAC (power level) and the new SAT code.
Telephony: The automatic channel change that occurs when a cellular user moves from one cell to another.
When a wireless network automatically switches a mobile call moving into an adjacent cell site.
The transfer of responsibility for a call from one cell site to the next. The process by which the MTSO, sensing by signal strength that cellular mobile is reaching the outer range of one cell, transfer or "hands off" the call to an adjacent cell with a stronger signal. See also Cell Site.
Transferring control of a flight to another ATC facility.
Transfer of duplex signaling as a mobile terminal passes to an adjacent cell in a cellular radio network.
The process of transferring the radar identification of an aircraft target and radio communications for that aircraft to another controller to ensure the uninterrupted provision of radar service. Fr: transfert
In cellular mobile systems, the process of transferring a phone call in progress from one cell transmitter and receiver and frequency pair to another cell transmitter and receiver using a different frequency pair without interruption of the call. In satellite communications, the process of transferring ground-station control responsibility from one ground station to another without loss or interruption of service.
Process by which a cellular telephone call is transferred from one cell site to another.
Refers to the process when a mobile phone call is automatically switched from one cell site to another as you move between coverage areas.
Transfers calls from one cell system to the next with no loss of cellular or PCS call.
a transfer of responsibility of an aircraft from one controller to another including a frequency change (in FS, this involves both text and voice modes - they are automatic when choosing a controller into the ATC directory of Squawkbox)
The process of passing a Radio Frequency (RF) connection to another available channel either at the originating cell site, a neighboring cell site, or in another service provider's coverage area. As the subscriber moves from one location to another, the connection is continually handed off from channel to channel and from cell site to cell site.
The process by which the Mobile Telephone Switching Office passes a cellular phone conversation from one radio frequency in one cell to another radio frequency in another. The handoff is performed so quickly that users rarely notice.
A communication channel will be changed to a new communication channel (without the user's intervention) as the mobile terminal moves from from one cell to another. Handoff may involve the assignment of a new frequency, time slot, and/or spreading code depending upon the channel access method.
Passing control of an aircraft from one controller to another.
The process when a wireless network automatically switches a mobile call to an adjacent cell site with a stronger signal.
The act of transferring control of a mobile station from one base station to another. See also Soft Handoff, Hard Handoff.
The process, invisible to the user, of transferring a cellular phone conversation from one base station (cell tower) to another without interruption to the call. There are two types of handoffs: hard and soft. See Also: Base Station, Hard Handoff, Soft Handoff
An ongoing call is switched from one cell to another. In GSM,the term is Handover.
The transfer of a wireless call in progress from one transmission site to another site without disconnection.
A frequency channel will be changed to a new frequency channel as the vehicle moves from from one cell to another without the user's intervention.
The process of maintaining a radio link between a cellular radio telephone and the cellular system. The handoff occurs when the radio telephone moves out of range of one cell site and comes into range of another, relying on Received Signal Strength Indication (RSSI) to determine when handoff is necessary.
The process by which a cellular phone conversation is transferred from one BST to another without interruption. When a cellular user is in motion, in a car for example, and travels out of range of the original BST, the BSC acts as a switch and ensures that the call is effectively passed over to the next BTS. There are two types of handoffs: hard and soft. A hard handoff requires the connection to first be broken in the original cell before it is made in the successor cell. Hard handoffs are required in TDMA and GSM systems because these systems employ different frequencies in adjacent cells. A hard handoff may affect data communications adversely as information may be lost when the connection is broken before it is transferred. Conversely, a soft handoff does not require the original connection to be broken when entering an adjacent cell. Soft handoffs employ a “make and break†handoff algorithm. Soft handoffs are used in CDMA systems which do not require the use of different frequencies in adjacent cells. See also BSC, BST, TDMA and CDMA.
Switching a cellular phone transmission from one cell to another as a mobile user moves into a new cellular area
The process by which wireless subscribers traveling throughout the system coverage area are switched from cell to cell (and different channels) with better coverage for that particular area when poor-quality conversation is detected.
In cellular telecommunications, the term handoff refers to the process of transferring an ongoing call or data session from one channel connected to the core network to another. In satellite communications it is the process of transferring satellite control responsibility from one earth station to another without loss or interruption of service. The British English term for transferring a cellular call is handover, which is the terminology standardised within such European originated technologies as GSM and UMTS.
