Low throughput reason in lte 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. Low Throughput causes in the Downlink for LTE networks. Low Throughput causes in the Downlink for LTE networks. When a UE is at the cell border it will need to transmit a strong signal to reach the tower. of contributing factors which affect the end user 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. Uplink Interference – LTE uplink interference is caused by UEs near the cell border. Jan 11, 2024 · Although similar to DL throughput, UL throughput has special considerations to take when analyzing performance issues on a network. Counter name may vary from release to release. 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. 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 If devices like routers are experiencing performance degradation, faults, or are simply outdated then you can end up with low throughput. Step 1 Jul 12, 2021 · The general troubleshooting strategy is described below and the covered reasons for bad throughput are shown in the figure below. Definition of The SINR> 10dB and UL throughput< 0. 83Mbps, there are 139 records. Low Cost (As low as an EGPRS modem) Low Energy Consumption; As I said there is no problem with achieving Low Throughput with the current LTE implementation, but there would be limitation to achieve Low Cost, Low Energy Consumption as required in this area (Actually Low Throughput itself is not a goal of the design. So, in stead of directly jumping into max throughput test, increase the throughput step-by-step and check CPU utilization (e. . Oct 21, 2019 · The RACH resource adjustment function adaptively adjusts the PRACH configuration index based on the RACH load in a cell. Ericsson defined throughput (UL or DL) is "the speed at which packets are being transferred by the time the first packet has been scheduled in the air interface". It is because there is some subframes where you cannot allocate full RBs (100 RBs in case of 20Mhz, Cat 3). The customer was notified and replaced the 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. Speaking of low quality area, you might want to look up to pZeroNominalPusch and pZeroNominalPucch parameters as having them too high will higher signal power that might increase interference Feb 21, 2023 · If low CQI values are found after a CQI report is obtained, then downlink interference might be the cause of low throughput. This can occur due to distance from the cell tower or obstacles like Dec 29, 2022 · The fairness or not of the scheduler will impact not only how an UE in a low quality area is treated, but also it will shape the overall cell throughput. There is not one factor, but a number. #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. Step 1: Identify cell with low UL (uplink) throughput a) The first thing is to identify those cells with low throughput. Step 5: Low Demand a) Run areportusingthe counters provided by the OEM to find. There are 574 records left. It outlines steps to analyze downlink and uplink throughput from a performance counter perspective. 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. Feb 18, 2024 · Low throughput in LTE networks can be attributed to various factors, both within the network and at the user equipment (UE) level. PREREQUISTE : General Guidelines Before diving into Throughput Investigation: #LTELowThroughput #4GLowThroughput#CQI #4GCQISubscribe Like & Share. In LTE, end user quality of service is impacted by the cumulative effect of various nodes and interfaces. 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 This document summarizes a case study of an LTE low throughput issue. Here are some common reasons for low throughput in network: 1. Likewise, if computer networks are congested with lots of traffic then packet loss will occur. be/FL7CqL6E734LTE(4G Reason for low throughput LTE. Low Throughput causes in the Uplink for LTE networks. Step 1: Identify cell with low DL (downlink) throughput a) The first thing is to identify those cells with low throughput. 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?
