CDMA (Code Division Multiple Access) and TDMA (Time Division Multiple Access) are two different types of multiple access technologies used in telecommunications to manage how multiple users share the same communication channel. CDMA allows multiple users to occupy the same channel simultaneously by assigning unique codes to each user, which enables the separation of signals. … Read more
1xEV-DO, or 1x Evolution-Data Optimized, refers to a high-speed data technology used in CDMA (Code Division Multiple Access) networks. It is designed to enhance data transmission rates for mobile devices, providing faster internet access compared to earlier technologies. 1xEV-DO improves performance by optimizing the way data is transmitted over the network, allowing for better support … Read more
CDMA, or Code Division Multiple Access, is a digital cellular technology used in mobile communications. It allows multiple users to share the same frequency channel by assigning unique codes to each call. This method of spreading signals over a wide frequency band makes CDMA efficient in managing network capacity and reducing interference. What is CDMA … Read more
GSM stands for Global System for Mobile Communications. It is a standard developed to facilitate mobile communication across different networks and regions. GSM defines the protocols for mobile telephony that enable voice and data services, allowing users to make calls, send text messages, and access mobile data services on a global scale. A GSM number … Read more
The Home Location Register (HLR) is a central database in mobile networks responsible for storing and managing subscriber information. It maintains details such as user profiles, subscription data, and current locations of subscribers. The HLR plays a crucial role in facilitating call routing, managing network resources, and supporting various network services. It is primarily used … Read more
GSM only” refers to a mobile phone or device that supports only the GSM network standard. This means that the device can only connect to networks using GSM technology and will not be compatible with other network standards such as CDMA, 3G, or LTE. This is relevant in regions where GSM is the primary mobile … Read more
HLR and VLR in mobile computing, as discussed on Javatpoint, are fundamental components in the architecture of mobile networks. The Home Location Register (HLR) is a central database that stores permanent subscriber information, including user profiles, service subscriptions, and authentication details. The Visitor Location Register (VLR) is a temporary database that handles information about subscribers … Read more
UMTS, or Universal Mobile Telecommunications System, is a third-generation (3G) mobile cellular system for networks based on the GSM standard. It provides higher data transfer rates and more efficient use of the available radio spectrum compared to its predecessors. UMTS supports a range of services, including high-speed internet access, video calling, and mobile TV. It … Read more
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
