Step 1: Identify cell with low UL (uplink) throughput a) The first thing is to identify those cells with low throughput. Likewise, if computer networks are congested with lots of traffic then packet loss will occur. #LTELowThroughput #4GLowThroughput#CQI #4GCQISubscribe Like & Share. This document provides an overview of the solution process for analyzing the root causes of sudden dropping throughput and low throughput in LTE networks. The process involves filtering out top cells, checking basic parameters and alarms, evaluating problem routes, analyzing coverage of problem data points, demarcating faults and locating the root cause for problem routes. 72, the record is as below: When -115dB <=RSRP <= -120dB, the mean throughput is 0. Poor Signal Strength: Weak signal strength) can significantly impact throughput. Low Throughput causes in the Downlink for LTE networks. Here are some common reasons for low throughput in network: 1. It outlines steps to analyze downlink and uplink throughput from a performance counter perspective. In no particular order, here are some of the pointers: BLER (Block Error Rate) – The BLER should be less or equal to 10%. be/FL7CqL6E734LTE(4G Feb 13, 2024 · Low Throughput causes in the Downlink for LTE networks. 4, Analysis of the data . Dec 29, 2022 · Throughput is a basic KPI on any LTE network. Let's delve into the technical details of throughput in LTE: 1. I have added Huawei and Ericsson DL user throughput formula at the end of this post, just as reference as they might not been updated. Step 1: Identify cell with low DL (downlink) throughput One simple and obvious rule in throughput is "Higher Layer throughput can never be larger than Lower Layer throughput". There are 574 records left. 122 Mbps. The analysis flow includes checking KPIs, parameters, and features related to coverage 5G EN-DC Call Drop//Mute Issue Troubleshooting Points: https://youtu. Jul 12, 2021 · The general troubleshooting strategy is described below and the covered reasons for bad throughput are shown in the figure below. . What are main reasons of Low Throughput in 4G LTE? There are too many Reason is possible Low Throughput Issue 1 - Poor coverage (BLER) 2 - Avaibility issue 3 - Uplink Interference 4 - A poor RACH Jan 2, 2024 · Throughput in LTE (Long-Term Evolution) refers to the actual data transfer rate or the amount of data transmitted over the network in a given time period. The customer was notified and replaced the Reasons of low throughput (4G) Low throughput in LTE networks can be attributed to various factors, both within the network and at the user equipment (UE) level. Definition of What are main reasons of Low Throughput in 4G LTE There are too many Reason is possible What’s the BW configured in transmission level? Low mcs, Low sinr, Low rsrq , high prb usage, wrong earfcn May 17, 2012 · Low Throughput causes in the Uplink for LTE networks. Another thing to consider is that throughput can be discriminated by QCI. Domain Support Specialist at Ericsson India Pvt Ltd in Bharti SRF Team | Ex Dy Manager Reliance industries Ltd NHQ Mumbai| LTE & NR-5G ZTI & Manual Integration What are main reasons of Low Throughput in 4G LTE - Read online for free. Feb 5, 2017 · The general troubleshooting strategy is described below and the covered reasons for bad throughput are shown in the figure below. The output is the Sep 27, 2014 · b) If low CQI values are found after a CQI report is obtained, then downlink interference might be the cause of low throughput. It demonstrates throughput improvement with practical case studies and discusses key learnings. 08 Mbps. The document lists many potential reasons for low throughput in 4G LTE networks, including: 1. There are 116 records. be/YRDeatn6np0Huawei LTE SIBs Parameters (SIB1,2,3,4):https://youtu. Low Throughput causes in the Downlink for LTE networks. Graphs and tests showed high quality wireless signals but evidence of transmission problems. Putting it another way using a specific case, IP layer throughput can never be larger than L1/PHY layer throughput. Jun 24, 2021 · What is the reason for low throughput? If devices like routers are experiencing performance degradation, faults, or are simply outdated then you can end up with low throughput. The mean SINR is 2. The SINR> 10dB and UL throughput< 0. c) Common sources of interference in the 700 MHz band (LTE deployment in the USA) are: inter-modulation interference, cell jammers and wireless microphones Low throughput in LTE networks can be attributed to various factors, both within the network and at the user equipment (UE) level. This document summarizes a case study of an LTE low throughput issue. It is a critical metric that directly impacts the user experience and the efficiency of the wireless network.
