Effective Isotropic Radiated Power (EIRP) is a measure of the radiated power by an antenna in a particular direction, accounting for both transmitter power and antenna gain. It’s essential for ensuring compliance with regulatory power limits in wireless communication systems and helps engineers select antennas for optimal signal strength and coverage. EIRP is expressed in … Read more
Beamforming is a technique in multiple antenna systems that focuses transmitted signals (Transmit Beamforming) or selectively listens to signals from a specific direction (Receive Beamforming). It’s accomplished by adjusting the phase and amplitude of signals from individual antenna elements, creating a concentrated “beam” of RF energy. Beamforming enhances wireless communication range, reduces interference, and increases … Read more
How do you calculate total radiated power antenna? Calculating the total radiated power (TRP) of an antenna involves determining the power radiated in all directions by the antenna. The TRP is a measure of how effectively an antenna transmits energy into free space. Here’s a detailed explanation of how to calculate the TRP of an … Read more
Yes, MIMO (Multiple Input Multiple Output) technology entails the use of multiple antennas at both the transmitter (MIMO-TX) and receiver (MIMO-RX) ends of a communication system. This enables simultaneous transmission of multiple data streams, enhancing data rates, reliability, and performance in wireless communication standards like 4G LTE and 5G. Does MIMO mean both transmitter and … Read more
Time Division Duplexing Long Term Evolution (TDD-LTE) is a wireless communication technology used in 4G LTE networks. It enables simultaneous data transmission in both directions by dividing time into frames and dynamically allocating time slots for uplink and downlink traffic. TDD-LTE is known for its flexibility, high spectral efficiency, and suitability for applications like mobile … Read more
What is the secondary synchronization signal in LTE? The Secondary Synchronization Signal (SSS) in LTE is a signal transmitted periodically by the base station (eNodeB) to assist mobile devices (UEs) in identifying the specific cell they intend to connect to. It carries information about the cell’s identity group and cell identity, ensuring that UEs accurately … Read more
The primary synchronization signal (PSS) in LTE is a signal transmitted periodically by the base station (eNodeB) to help mobile devices (UEs) synchronize with the cell they want to connect to. It carries vital timing and frequency information, allowing UEs to identify the cell, align their synchronization, and establish communication within the LTE network. What … Read more
Another term for Long-Term Evolution (LTE) is “4G LTE,” where “4G” stands for “Fourth Generation.” LTE is the technology standard for high-speed wireless communication that followed the 3G (Third Generation) technology. It is often referred to as 4G LTE to emphasize its fourth-generation status and its capability to provide faster data speeds and improved network … Read more
The interface name between the eNodeB (Evolved Node B) and the SGW (Serving Gateway) in an LTE network is called the “S1 Interface.” It serves as the crucial link for communication, handling tasks such as bearer management, control signaling, and the transfer of user data packets between the base station (eNodeB) and the core network … Read more
The interface between a User Equipment (UE) and an evolved NodeB (eNodeB) in LTE or 4G networks is called the “Uu interface.” It’s a wireless link that handles all communication between your mobile device (UE) and the cellular base station (eNodeB). This interface manages radio resources, ensures data reliability and security, supports various services, and … Read more
