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
Affects of the Channel in LTE MIMO To understand the impact of the channel, let’s assume that the base station receiver is facing many challenges in the same MIMO receiver that universal areas, but also must receive data simultaneously from multiple users. In terms of MIMO UM, each signal is derived from a separate UE, … 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
Advantages of Intelligent Network (IN) Concept of Intelligent Network: The introduction of new services and access to the GSM service are based on the concept of Intelligent Network (IN). This is because of the independence between: Conventional call processing handled by the exchange, Mobile radio functions handled by a dedicated server. Dialog between these two … Read more
As From the Name VLR means Visitor Location Register and HLR means Home Location Register so HLR having all detail of subscriber and VLR having temporary details for mainly call processing related. Let’s check in detail HLR and VLR in Function in telecom. Hlr and Vlr in Mobile Communication Home Location Register (HLR) – Main … Read more
The radio waves are distributed in 3Hz ~ 3000GHz. This spectrum is divided into 12 bands, as shown in the above table. The frequencies in each specific band present unique propagation features: The lower the frequency is, the lower the propagation loss will be, the farther the coverage distance will be, and the stronger the … Read more
Radio wave can be propagated from the transmitting antenna to the receiving antenna in many ways: perpendicular incidence wave or ground refraction wave, diffraction wave, troposphere reflection wave, ionosphere reflection wave, as shown in the diagram. As for radio wave, the most simple propagation mode between the transmitter and the receiver is free space propagation. … Read more
The Logical Channel is used in time multiplex in a physical channel, which is categorized according to the types of messages transmitted in the physical channel. Different logical channels are used in transmission of different types of information between BS and MS, such as the signaling or traffic data. In GSM system, five different types … Read more
When we talk about Mobile Business then its worst useful without authentication means to make Network as business all user required to be authenticate lets understand how authentication done in gsm. Authentication Center (AUC) The AUC is a processor system, it performs the “authentication” function. It will normally be co-located with the Home Location Register … Read more
