LTE TDD (Long-Term Evolution Time-Division Duplex) is a variant of LTE that uses time-division multiplexing to separate uplink and downlink transmissions within the same frequency band. In LTE TDD, the same frequency band is used for both transmitting and receiving data, but at different times. This allows for more flexible and efficient use of the … Read more
What is 3G and what is it used for? 3G, or the third generation of mobile telecommunications technology, is designed to provide faster data transfer rates and enhanced voice quality compared to its predecessors. It supports a wide range of services, including internet browsing, email, video calling, and multimedia messaging. 3G technology enables mobile devices … Read more
3GPP stands for the “3rd Generation Partnership Project.” It is a collaboration between various telecommunications standards organizations aimed at developing and maintaining global technical specifications and standards for mobile communications. The project was originally focused on 3G technologies but has since expanded to include 4G, 5G, and future mobile communication standards. What does 3GPP mean? … Read more
The difference between SRVCC (Single Radio Voice Call Continuity) and VoLTE (Voice over LTE) lies in their functions and roles within a network. VoLTE is a technology that allows voice calls to be carried over the LTE network, providing high-definition voice quality and enabling simultaneous voice and data usage. SRVCC, on the other hand, is … Read more
3GPP is owned by its member organizations, which include a range of industry stakeholders such as telecommunications operators, manufacturers, and other entities involved in mobile communications. The project operates through a collaborative model where these members contribute to the development and maintenance of global standards for mobile networks. Who founded 3GPP? 3GPP was founded by … Read more
PUCCH (Physical Uplink Control Channel) is a channel in cellular networks used for transmitting control information from the user equipment (UE) to the base station. It carries uplink control information such as acknowledgments, scheduling requests, and channel quality indicators. What is Pucch and UCI or its format? UCI (Uplink Control Information) refers to the information … Read more
LTE450 refers to a specific implementation of LTE (Long-Term Evolution) technology that operates in the 450 MHz frequency band. This variant of LTE is designed to offer mobile broadband services in rural and underserved areas where lower frequencies provide better coverage and signal penetration. LTE450 can deliver data rates and performance similar to other LTE … Read more
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 … Read more
MNC stands for Mobile Network Code, MCC stands for Mobile Country Code, and LAC stands for Location Area Code. The MNC is a code that identifies a specific mobile network operator within a country, the MCC identifies the country itself, and the LAC is used to identify a particular area within the network’s coverage region. … Read more
Yes, there was a 1G network, which refers to the first generation of mobile telecommunication systems. The 1G network primarily used analog technology to provide basic voice communication services. It was the first step in the evolution of mobile networks, marking the beginning of mobile telecommunications. There are no 1G networks left in operation today. … Read more
