The VLR (Visitor Location Register) works by managing the temporary details of mobile subscribers who are roaming outside their home network. When a subscriber enters a new network area, the VLR in that area temporarily stores information about the subscriber, such as their location and service availability. It communicates with the HLR (Home Location Register) … Read more
Node B in telecommunications refers to the base station in a 3G UMTS (Universal Mobile Telecommunications System) network. It serves as the interface between mobile devices and the network, handling the transmission and reception of radio signals. Node B is responsible for converting radio signals to digital signals and vice versa, facilitating communication between mobile … Read more
BSC in telecommunications stands for Base Station Controller. It is a critical component in 2G GSM (Global System for Mobile Communications) networks. The BSC manages the radio resources for multiple Base Transceiver Stations (BTS) within a network. Its primary functions include managing handovers between BTSs, allocating frequencies, controlling power levels, and ensuring efficient use of … Read more
A cell phone repeater, also known as a signal booster, amplifies weak cellular signals to improve reception and call quality in areas with poor signal strength. It works by receiving the existing weak signal through an external antenna, amplifying it using an amplifier, and then retransmitting the strengthened signal indoors through an internal antenna. This … Read more
PLMn (Public Land Mobile Network) refers to a network operated by a particular mobile operator that provides land-based wireless telecommunications services to users within a specific geographic area. The PLMn identifies the network and its associated services, ensuring that mobile devices connect to the correct network for communication, roaming, and service access. What is PLMn … Read more
In a Multi-Carrier Wireless Communication (MCWC) system, the Home Location Register (HLR) and Visitor Location Register (VLR) serve distinct roles. The HLR is responsible for maintaining a subscriber’s permanent data, such as their profile and subscription details. It stores information about user identities, such as the International Mobile Subscriber Identity (IMSI), and is crucial for … Read more
The Serving GPRS Support Node (SGSN) and Gateway GPRS Support Node (GGSN) are two key components in the GPRS (General Packet Radio Service) architecture within mobile telecommunications. The SGSN is responsible for managing and delivering data packets to and from mobile devices within its coverage area, including tasks such as mobility management, session management, and … Read more
CDMA (Code Division Multiple Access) in a cell phone refers to a technology used for cellular communication that allows multiple users to share the same frequency band by assigning unique codes to each user’s signal. This method enables efficient use of the available spectrum and provides a way to handle numerous simultaneous calls and data … Read more
