What is A5 Inter-Frequency Handover in LTE? In LTE, A5 inter-frequency handover refers to the process of transferring an active mobile device (User Equipment or UE) from one frequency band to another during an ongoing call or data session. This process occurs when the network decides that the current frequency is no longer suitable for … Read more
What is a TAC in LTE? The TAC, or Tracking Area Code, is a crucial element in the architecture of Long-Term Evolution (LTE) networks, which are designed for high-speed mobile communications. TAC is used to manage the location of mobile devices within the network, facilitating efficient communication, mobility management, and network resource allocation. It provides … Read more
What is a Tracking Area in LTE? Let me explain what a tracking area (TA) is in LTE, and why it’s essential for network operation. A Tracking Area is a designated geographical region within a mobile network where user equipment (UE), such as smartphones or tablets, can be tracked for location-based services. The concept of … Read more
What is a RACH Attempt in LTE? In LTE, the Random Access Channel (RACH) is a critical mechanism used by the User Equipment (UE) to establish communication with the network, particularly when the device is trying to connect to the network for the first time or after it has been in idle mode. A RACH … Read more
What is a Reference Signal in LTE? In LTE (Long Term Evolution), a Reference Signal (RS) is a known signal that is transmitted by the base station (eNodeB) and received by the User Equipment (UE) to help measure the quality of the radio signal. Reference signals are crucial for a variety of functions such as … Read more
What is a Resource Block in LTE? In one of the previous articles, we explored how LTE uses OFDM to transmit data efficiently. Now, let me explain how that data is organized and sent — and that’s where Resource Blocks come in. If you understand Resource Blocks, you’ll have a clearer view of how the … Read more
What is a High Signal-to-Noise Ratio (SNR)? Signal-to-Noise Ratio (SNR) is a measure used in telecommunications to quantify the quality of a signal compared to the level of background noise. In simple terms, it tells you how clear or strong your signal is relative to the unwanted noise. A high SNR means that the signal … Read more
What is an IFHO in LTE? An Inter-Frequency Handover (IFHO) in LTE refers to the process of transferring a mobile device’s connection from one cell to another, but this time, the handover occurs between cells operating on different frequencies. The goal of IFHO is to maintain continuous service as the user moves across different frequency … Read more
What is a Low RSRP? Reference Signal Received Power (RSRP) is a measurement used in LTE networks to evaluate the strength of the reference signal received by a mobile device (User Equipment, UE). The RSRP is critical in determining the quality of the signal and plays a key role in handover decisions and cell selection. … Read more
What is a Good SINR? SINR stands for Signal-to-Interference-plus-Noise Ratio, and it is a key metric in wireless communication systems like LTE and 5G. SINR measures the quality of the signal received by the user equipment (UE) relative to the interference and noise present in the network. The higher the SINR, the better the quality … Read more
