In telecommunications, a Tracking Area Code (TAC) is a unique identifier used to designate a specific area within a network where mobile devices can be tracked. The TAC helps the network manage device locations and support efficient handovers as devices move between different tracking areas. It is an essential component in both 4G and 5G networks for mobility management and efficient data routing.
A Tracking Area Code (TAC) is a numeric code that uniquely identifies a tracking area within a cellular network. It is used to segment the network into manageable areas to facilitate the tracking of mobile devices. Each TAC corresponds to a particular geographic region within the network, allowing for efficient location management and signaling.
In 5G, the Tracking Area Code (TAC) continues to serve its role as a unique identifier for tracking areas. It is used in combination with a Network Identifier (NID) to create the Tracking Area Identifier (TAI), which provides a globally unique identifier for tracking areas. The TAC in 5G helps in managing the location of devices and routing data effectively within the network.
In 4G, the Tracking Area Code (TAC) is used to identify specific tracking areas within the network. The TAC allows the network to manage devices efficiently as they move from one tracking area to another. It is part of the Tracking Area Identifier (TAI), which includes both the TAC and a Network Identifier (NID) to ensure unique identification of tracking areas.
The range of Tracking Area Codes (TAC) typically consists of a numeric value within a specified range. The TAC is usually a 16-bit number, allowing for a maximum of 65,536 unique TAC values. This range provides sufficient granularity to identify a large number of tracking areas within a network, accommodating both large and small network deployments.
