What is MNC and MCC for GSM MCC MNC – Telecom What is mcc and mnc :- Both are very first question in your mind when you start learning on telecom its basic behind numbering system in telecom lets understand each one in details. MNC full form in telecom : Mobile Network Code. MCC full form in telecom … Read more
Radio Protocol Architecture in LTE The EUTRAN radio protocol model specifies the protocols terminated between UE and eNB. The protocol stack follows the standard guidelines for radio protocol architectures (ITU-R M1035) and is thus quite similar to the WCDMA protocol stack of UMTS. The protocol stack defines three layers: the physical layer (layer 1), data … Read more
In GSM, the Network Identity Parameter CGI (Cell Global Identity) is a code that uniquely identifies a specific cell in a mobile network. It comprises the Mobile Country Code (MCC), Mobile Network Code (MNC), Location Area Code (LAC), and Cell Identity (CI). The CGI helps in identifying and differentiating cells within a GSM network, facilitating … Read more
LTE TCP Throughput vs Round Trip Time (RTT) In Long-Term Evolution (LTE) networks, the relationship between TCP throughput and Round Trip Time (RTT) is a critical factor influencing the performance of data transmission. Let’s explore the key considerations: TCP Throughput: Definition: TCP (Transmission Control Protocol) throughput refers to the rate at which data can be … Read more
LTE Possible Dimensioning Concepts LTE network dimensioning involves planning and optimizing various aspects of the network to ensure efficient use of resources and meet performance objectives. Here are some key dimensioning concepts in LTE: Coverage Dimensioning: Cell Size: Determine the coverage area of each cell based on the expected traffic density, terrain, and interference considerations. … Read more
OFDMA Principles in LTE Orthogonal Frequency Division Multiple Access (OFDMA) is a key technology used in Long-Term Evolution (LTE) to efficiently manage the transmission of data over the radio interface. Here’s an explanation of OFDMA principles in LTE: Frequency Division Multiplexing (FDM): OFDMA uses FDM to divide the available frequency spectrum into multiple subcarriers. Each … Read more
How 26 and 51 Multiframes in GSM GSM is very complicated when we talk about its rf side and in it very complicated to understand the structure of 26 and 51 Multiframes, here my try to make you understand simply. The 26-frame Traffic Channel Multiframe in GSM The Below Figure shows the time relationship between … Read more
What is VSWR (Voltage Standing Wave Ratio) and How tilting antenna VSWR means voltage standing wave ratio which everyone knows but why it comes to calculate in Telecom? When BTS transmit any signal (LTE, CDMA, GSM, WCDMA anyone) then in radio wave transmit through cable and reach to antenna so what? Now I give you … Read more
What are Interference and its source, effect and types in GSM Interference is the sum of all signal contributions that are neither noise not the wanted signal. Lets understand how its effect, its type and what possible source for it. Effects of Interference Interference is a major limiting factor in the performance of cellular systems. … Read more
How and What Spatial Diversity Antenna Systems in GSM The spatial diversity antenna system is constructed by physically separating two receiving base station antennas. Here I write on spatial diversity antenna system criteria, configuration. SPATIAL DIVERSITY ANTENNA SYSTEMS Once they are separated far enough, both antennas receive independent fading signals. As a result, the signals … Read more
