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. 4, Analysis of the data . Low Throughput causes in the Downlink for LTE networks. Here are some common reasons for low throughput in network: 1. Putting it another way using a specific case, IP layer throughput can never be larger than L1/PHY layer throughput. Another thing to consider is that throughput can be discriminated by QCI. This post is to address common issues that affects downlink throughput and also to dig into possible solutions. The SINR> 10dB and UL throughput< 0. When RSRP < -120dB, the mean throughput is 0. 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. Is one of the three major KPI, along with and latency and packet loss when we measured what it’s called “the integrity” network. Likewise, if computer networks are congested with lots of traffic then packet loss will occur. The issue was caused by high packet retransmission rates between the eNodeB and the operator's core network, due to an old Ethernet card on the uplink microwave with a small buffer. This document summarizes a case study of an LTE low throughput issue. 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. #LTEOPTIMIZATION #LTE # LTESOFFPARAMETERSPoor CQI Reason in 4G & Optimization?https: In WCDMA, HSDPA, HSUPA probably 'Yes', but in LTE you would still have a little low throughput than the 3GPP spec value even in PHY throughput. It outlines steps to analyze downlink and uplink throughput from a performance counter perspective. Thus, the following analysis aims to identify three main causes of throughput degradation, listed in Table III, from the analysis of the obtained SHAP Summary Plot In WCDMA, HSDPA, HSUPA probably 'Yes', but in LTE you would still have a little low throughput than the 3GPP spec value even in PHY throughput. b) If the maximum number of RRC connections active per cell is close or equal to the maximum number of RRC connections supported, then. There are 98 records. 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. Jul 12, 2021 · The general troubleshooting strategy is described below and the covered reasons for bad throughput are shown in the figure below. Let's delve into the technical details of throughput in LTE: 1. The cause for low throughputis load. 122 Mbps. It is because there is some subframes where you cannot allocate full RBs (100 RBs in case of 20Mhz, Cat 3). 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. be/YRDeatn6np0Huawei LTE SIBs Parameters (SIB1,2,3,4):https://youtu. It is a critical metric that directly impacts the user experience and the efficiency of the wireless network. The mean SINR is 2. Here are some common reasons for Diagnosing the causes of low throughput is a complex process that requires in-depth knowledge of the network operation, being often a time-consuming task for the network engineers. #LTELowThroughput #4GLowThroughput#CQI #4GCQISubscribe Like & Share. Counter name may vary from release to release. 72, the record is as below: When -115dB <=RSRP <= -120dB, the mean throughput is 0.
