    1. What is throughput in lte of contributing factors which affect the end user throughput. Let our guide simplify your decision-making for the perfect fit for your device. There is not one factor, but a number. 4, 3, 5, 10, 15, or 20 MHz, giving Throughput (also known as the flow rate) is a measure of a business process flow rate. Frequency Bandwidth. Here As LTE Rel. By mastering the LTE throughput formula and using the provided 4G throughput calculator, you can make informed decisions about network performance and capacity. Calculator is based on 3GPP 36. The specific utilization of these events may vary based on the network The Long Term Evolution (LTE, 4G ) standard defined by the 3GPP supports both FDD and TDD Duplex mode. As LTE uses different channel bandwidths both for FDD and TDD. LTE-M provides less data throughput with 300kbps - 1Mbit/s in uplink and downlink. The high bandwidth applications typically use networks called LTE Advanced (LTE-A) or LTE Advanced Pro. Long Term Evolution—Advanced (LTE-A) is the most widely used and encouraging technology for 4G and 5G mobile networks. On the other hand, we need to determine how many ph LTE-Advanced can support peak download data rates of up to 1 Gbps and LTE-Advanced Pro can provide maximum data rates of up to 3 Gbps. It has a narrower bandwidth of 1. LTE Cat-1 bis offers higher throughput than LTE-M and NB-IoT, making it ideal for applications requiring moderate data rates and global connectivity. Compared to its predecessor, it offers better data speed with lower latency. The analysis is Estimating the Maximum Throughput and 5G Capacity for modern Wireless Networks is complex and requires understanding of the 5G standards. LTE isn’t just a buzzword; it’s a globally recognised, open, and interoperable wireless standard. It is a critical metric that directly impacts the user experience and the efficiency of the wireless network. This example data are captured from a RLCs for IP throughput test LTE, which stands for Long-Term Evolution, is a standard for wireless broadband communication. Asynchronous HARQ – used in LTE Downlink transmission. 4G/LTE - Access Control Quick Reference Access Confrol (ac-Barring, SSAC, EAB, Cell Barring) Ack/Nack Repetition; A-GPS; AKA (Authentication and Key Agreement) Throughput : LTE : Overall Factors; Throughput : LTE : PHY Performance; Throughput : LTE : RLC/PDCP Factors; Throughput : LTE : Readings/Test Networks on LTE bands 7, 28 (LTE-FDD) are suitable for global roaming in ITU Regions 1, 2 and 3. Throughput (Integrity): In 4G/LTE TK network the main indicators which measure the bit rate in downlink are: Max App DL throughput (kbps) and Avg App DL throughput (kbps), whereas for uplink Max App UL throughput (kbps) and Avg App UL throughput (kbps). For very high data rate application (e. However, NB-IoT does have some advantages over LTE-M. The suitable 4G LTE module can be selected according to the market. LTE utilises the LTE UE Category or User Equipment categories or classes to define the performance specifications of LTE devices and enables LTE base stations to be able to communicate effectively with them knowing their performance levels. BLER (in LTE) = Number of erroneous blocks / total number of received blocks. 5G delivers a quantum jump in network speed, data throughput, low latency, and ultra-reliability. It uses advanced modulation techniques and wider frequency bands to achieve faster data rates. LTE is one of the most popular cellular technology standards and has a Table 2 –LTE Categories and Corresponding Throughput Gains. Although LTE is commonly referred to as 4G LTE, LTE is technically slower than 4G but still faster than normal 3G. With the introduction of network slicing in 5G, this is changing. LTE-M's faster speeds also make it better for more data-intensive IoT applications. Each table has 15 modulation/coding rate combinations. Some TM is designed mainly to increase throughput, some are to increase communication reliability and some are to handle multiple users simultaneously etc This site is for everything on 4G/LTE. Asynchronous HARQ, on the other hand, is a technique in which So, you would want to know the correlation between data throughput and the signal quality. LTE-M deployment can be done in-band within a standard LTE carrier or standalone in a dedicated spectrum. The radio roundtrip reductions when introducing the possibility of instant access in the uplink is 8 ms or more (i. the SR-to-grant roundtrip delay is removed, which is at least 8 ms) , and when reducing TTIs and processing LTE stands for Long Term Evolution It’s worth noting that LTE offers increased throughput and lower latency, dramatically improving on 3G network performance; in terms of speed, 4G LTE is 5-10 times faster than 3G. UE Category is the set of information (parameters) that defines the maximum throughput for a UE. If you have read my previous block “Improving low DL throughput in LTE“, you will notice the extreme similarity of how throughput is measured in UL and DL. DL-SCH,UL-SCH,data rate etc. To obtain the correct result, it is necessary to enter such important parameters as: mode of 5G network, number of aggregated carriers, number of MIMO layers, For example, a network may have a speed of 100 Mbps. In mobile networks, the end user throughput is the amount of information received in bits /second. Most modern smartphones, While carrier marketing sometimes suggests that 4G LTE is an enhanced version of 4G, 4G LTE actually refers to devices and networks that are evolving from the slower 3G standard to full 4G speed and throughput capability. It’s the lifeline for UEs to gain initial access and transmit data efficiently. The LTE technology in wireless networks has achieved a significantly high throughput because it makes use of multiple access schemes. 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. Lower latency Besides faster throughput, LTE offers much lower latency than 3G, which means fewer network delays or lag times. Main; 5G; LTE; Webinars; Menu Also see how to calculate LTE throughput using MCS and LTE throughput calculator. LTE - RLC Factors . MIMO also offers other benefits through spatial diversity and beamforming. Packet arrival is key to high-performance service within a network. It achieves these enhancements through various technical This tutorial explains how LTE downlink maximum throughput is determined. e. O-RAN Load and If I define LTE Integrity Protection Procedure with this logic, it would be "a process that convert 'K' value from USIM into PDCP MAC-I and NAS MAC(Message Authentication Code)". This plot is automatically generated by AZQ Reporting tool and I just In this letter, a comprehensive analysis of throughput performance statistics in a live LTE network is presented. Following is an explanation of how to calculate the average throughput for PDCP layer in LTE network. There is a hard limit to how much data can be transmitted in a given bandwidth – this limit is well-known as the Shannon Stateful Firewall Throughput: 250 Mbps: 250Mbps: 700 Mbps: 700 Mbps: Maximum VPN Throughput: 100 Mbps: 100Mbps: 400 Mbps: 400 Mbps: Security Throughput: 200 Mbps: 200 Mbps: 400 Mbps: 400 Mbps: PoE Capabilities : No: Will the LTE devices be available in the USA and Worldwide? Yes. LTE-Advanced was specified in 3GPP release 10, whereas LTE-Advanced Pro was specified in release 13. In TDD LTE, we can dynamically change the uplink and downlink capacity to match the requirement or the demand. There are three types of CA, depending on the CC combination as shown in Figure 4. We propose an iterative heuristic optimal resource allocation (HORA) algorithm and Moving from LTE to 5G will result in superior bandwidth, devices, and dependability, but will require more complex infrastructure. I got the log captured by the tool and exported the data as csv file and then plot it on Microsoft Excel. 306 (HSPA) is to understand that there are several assumption behind the table which are not explicitely Throughput Optimization. The Cellular Landscape and Global Standardisation. There is a total of 6 different tables as of 3gpp release 15. LTE Evolved Packet Core. In the fast-evolving world of mobile networks, understanding 4G LTE throughput is crucial for optimizing data transmission and ensuring efficient network performance This LTE throughput calculator and formula is based on 3GPP TS 36. In this case, throughput is lower than network speed due to real-world limitations. LTE uses less power, so it’s more power-efficient. LTE, as per 3GPP Release 8, provides peak data rates of up to 300 Gbps, LTE-Advanced (Long-Term Evolution Advanced) is a standard that builds upon the initial 4G LTE (Long-Term Evolution) technology, aiming to deliver higher data speeds, improved network capacity, and overall enhanced performance compared to basic 4G LTE. 306 (LTE) or 25. This, as you imagine, can be a big source of frustration for network engineers. For this kind of multiple download, you LTE is short for Long Term Evolution and is a standard for 4G devices. It represents the fourth generation (4G) of mobile networks, succeeding the third generation (3G) technologies. At the beginning it seems to be simple, but as I getting deeper and deeper into this layer I get more and more confused. What makes 4G LTE different from 4G LTE is it connects to multiple internet sources and towers instead of a single tower to No headers. This standard was introduced in 3GPP Release 13 in 2016. Carrier Aggregation was initially introduced in LTE-Advanced networks, and today it is part of LTE-Advanced, LTE-Advanced Pro and 5G New Radio (NR) networks. This is a log captured from downloading a big file. 4. Carrier Aggregation: LTE-Advanced allows the combination of multiple frequency What is throughput LTE? What is throughput in warehousing? How do you calculate throughput time? Throughput is the actual amount of data that is successfully sent/received over the communication link. Synchronous HARQ – used in LTE Uplink transmission. g, LTE throughput test), downloading only one file would not push the enough data rate. The following calculations are made for user data bit rates on IP layer (including IP headers and LTE overhead, i. In LTE, end user quality of service is impacted by the cumulative effect of various nodes and interfaces. Factors that affect throughput. It is often referred to as 4G (fourth generation) technology, succeeding 3G (third generation). bis is an LTE standard developed specifically for IoT applications that is a variant of LTE Cat-1. It quantifies the amount of data that can be sent or received in a given period, typically expressed in bits per second (bps), kilobits per second (Kbps), megabits per second (Mbps), or gigabits per second For this comparison table, we have used the average download speeds of 30Mbit/s (4G LTE Cat6), 4Mbit/s (3G HSPA+) and 0. One of the most fundamental concepts in computer networking is to test the connectivity between two computers, here is where different measures to evaluate the performance of the network Both Bit Rate and Throughput measure the data transfer rate of a network connection, so both of them are measured by bit per seconds. Its key features include: 1. Below is the table explaining the LTE measurements events. 9†0Z$ cºQ LTE level throughput (e. [1] [2] LTE is the upgrade path for carriers with What is LTE and What Does LTE Stand For? LTE stands for "Long Term Evolution". MIMO allows for the simultaneous transmission and reception of data over different paths, improving signal quality, data throughput, and coverage. Just try to go through this illustration whenever you have chance and try to have your own idea first. Max num of ttached UE limitation would be ruled buy other factors like MME capacity or even eNB PUCCH capacity as LTE is the cellular technology that 4G networks are based on, and LTE Advanced is an enhancement that improves the original LTE technology. The average 4G data speed is what you normally get on your mobile device, whereas the peak speed is the maximum data rate the network can theoretically generate. 8 UE. (The reason is same as above) Long term evolution (LTE), standard for wireless broadband communication technology. The update makes it possible to make chipsets that are simpler and lower cost but still have the same throughput specs as the original LTE Cat 1 (10 Mbps down, 5 Mbps up, and latency Throughput measures how many packets arrive at their destinations successfully. TRB500 uses 4 antennas with 4×4 MIMO technology, which enables 5G network speeds with ultra-low LTE can enable peak download speeds of up to 300 Mbps and peak upload speeds of up to 75 Mbps. 6. 1Mbit/s (2G EDGE). Let’s assume, the UE is in good radio condition and its capability is available for 150 Mbps for downlink and 50 Mbps for uplink. The target figures for data throughput in the downlink is 1 Gbps for 4G LTE Advanced. Even when CQI is high, eNB may assign small resources due to various other factors) ii) Low throughput does not necessarily mean low CQI. This has led to the development of new technologies and services, such as mobile video conferencing and cloud-based applications, that were not possible with Data rate increased later with carrier aggregation and higher capability devices (Cat 6 / 9 / 12), and peak throughput of 450 Mbps or 600 Mbps is now available commercially in urban area. As of now CA can provides bandwidth up to 100 MHZ (20 MHZ * 5 Component carrier) Here both the CCs have different coverage and here we can use CA to get higher throughput at the areas where the coverage is overlapping. Please look at the table below that provides a summary of how LTE employs MIMO technology, using multiple antennas at both the user device and the base station. The physical uplink shared Channel (PUSCH) is used to transfer application data. LTE Cat 1bis modules, also known as LTE Category 1 bis, is a recent development in wireless communication standards that is emerging as a frontrunner in IoT and M2M communication. LTE throughput depends on the following parameters: Bandwidth; Channel quality The mid-range bandwidth is category LTE-1 . IxChariot. LTE EUTRAN: It is a radio access network standard meant to be a replacement of the UMTS, HSDPA and HSUPA . Here's a detailed explanation LTE (Long-Term Evolution, commonly marketed as 4G LTE) is a standard for wireless communication of high-speed data for mobile phones and data terminals. LTE MCS stands for Modulation and Coding Scheme and defines how many data can be transmitted. It is the technology behind 4G. A clear analysis of 4T4R performance data in a commercial FDD LTE network is presented in this paper. This is a simple and straightforward formula for data rate calculation. 4G/LTE - Measurement Report (High throughput depends not only on CQI, but also on transport block size (Number of RB and MCS. Essentially, it measures the movements of inputs and outputs within the production process. Is one of the three major KPI, along with and latency and packet loss when we measured what it’s called “the integrity” Almost whole of this site is about LTE. LTE is designed to offer significantly faster data rates, lower latency, and improved spectral efficiency compared to MIMO in 4G LTE networks is primarily used due to spatial multiplexing that improves data rates by using multiple antenna elements that are physically separated in space on a transmitter or receiver. The concept is just The maximum achievable LTE link throughput is assumed to be 150Mbit/s in this simulation and the transport network delay is omitted. LTE-M, which stands for LTE-Machine Type Conversely, if there’s too much overlapping downlink coverage, uplink interference can occur and the cell throughput can be reduced. emnify GmbH. This page is aimed at summarising what’s involved: 5G Maximum Capacity 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". slow LTE technology offers faster data speeds, lower latency, and improved capacity compared to its predecessors in the mobile network technology. Describing this process with illustration would be as follows. LTE is designed to provide higher data rates, lower latency, and better spectral efficiency compared to its predecessors. Physical layer data throughput can be calculated accurately for different scenarios. For TDD Case: You can find them. LTE enables faster data transmission rates, shorter delays, and improved capacity to handle more users compared to the older 3G. 1. [1] [2] The specification was frozen in 3GPP Release 13 (LTE Advanced Pro), in June 2016. This knowledge is Throughput is the actual rate that information is transferred. LTE Advanced Base Station. The throughput for a device working in a live network would vary at every moment It is recommended to read OFDMA/SC-FDMA sections to clearly understand throughput calculation in LTE. You can share your feedback, questions and/or proposals sending an email to alexey. RSRP refers to Reference-Signal-Receive-Power and measures the power of the reference signal received at the antenna of the device. Code Rate . Components of an LTE Network: Unveiling the Architecture. 8 standards, the CA provides the advantage of reducing redundant implementation. When LTE was first deployed table 1 was used, which only 5G is the fifth-generation mobile network designed to deliver reliable connectivity to mobile users and connected devices over high-band spectrum at speeds between 10 and 20 Gbps. What is Throughput? • The term throughput refers to ratio of data transmitted in unit of time. Long-Term Evolution Category 1 (LTE Cat-1) is a variation of 4G LTE technology specifically designed for the Internet of Things. When people use programs or software, they want their requests to be heard and It covers the same for 5G downlink throughput and 5G uplink throughput. Throughput is presented as kbps, Mbps or Gbps, and can differ from bandwidth due to a range of technical issues, including latency, packet loss LTE measurement Events . That correlation can be expressed as follows. The scenarios described are limited for specific scenario only. RSRP. Here is a table of LTE/NR CQI values and what modulation/coding rate is used: There are multiple CQI tables that can be used; Carriers can choose which CQI table to use. Some LTE UE Categories such as LTE Cat 3, LTE Cat 4 and LTE Cat 0 The subsequent development of LTE-Advanced (LTE-A) yielded peak throughput on the order of 300 Mbps. It is a solid basis for more demanding IoT use cases in terms of data traffic and features. Costa Rica, Venezuela, Brazil and some Caribbean countries or territories. LTE Cat1. Even with the improvements in spectral efficiency it is not possible to provide the required headline data LTE (Long Term Evolution) is a high-speed wireless communication technology. The obtained values for Uplink and Downlink for this TK network are the following: There has been a series of posts for LTE Throughput computation in both FDD and TDD. 4G LTE can achieve speeds of up to 300 Mbit/s downlink and 75 Mbit/s uplink, Carrier aggregation sends and receives data over multiple bands, increasing the amount of throughput for faster speeds. While LTE speeds reach 100 Mbps, true 4G offers speeds up to 1,000 Mbps. LTE EUTRAN (Evolved Universal Terrestrial Radio) 2. As part of the 3GPP Release 14 LTE-M also provides extended coverage and enables the reuse of the LTE installed base. 211 communication standards and allows you to calculate Max LTE Users depend on Bandwidth, CFI format, Aggregation CCE levels, DCI, etc. 5G speeds are exponentially faster than 4G speeds In the dynamic world of LTE networks, the Random-Access Channel (RACH) plays a vital role in establishing communication between UE and eNodeB. A workaround for this case is to download multiple files simultaneously. Each LTE band has a bandwidth of either 1. EE has launched this service in London, Birmingham, Liverpool and Manchester, with partial coverage in a number of other UK cities, under the name 4G+, while Vodafone has rolled it out to London, Birmingham, Manchester . LTE UE (User Equipment) Category & Class Definitions. Learn how the two standards are different. CSI helps the transmitter adjust the transmission parameters (e. Out of the given 8 DRBs what is the max value of default bearers that can be configured for a UE ? It only tells how much throughput the UE can achieve toward the SGW.

An advanced version of 4G LTE, its capabilities sit between 4G LTE and 5G. The previous paragraph described limitation of higher order modulation was a hallmark of 3G networks. Hardware Cost RSRP / LTE carrier RSSI (in Watts) or RSRQ = 10 log (N) + RSRP – LTE carrier RSSI (in dB) Where N is the number of resource block over the measured bandwidth (see table below) As it happened with RSRP this quantity is also used by the UE to rank cells for cell reselection and handover. , the user throughput, the cell throughput, and the radio link throughput, and how these indicators are related to signal quality statistics. The average download speed of LTE is around 15 to 20 Mbps. 4G/LTE - Protocol Stack RLC . 2. LTE is not used in 5G, which delivers even faster speeds and more capacity than LTE and 4G. The most common analogy used to describe the relationship between the two is to consider bandwidth as a pipe and throughput as water. cat6),category-7(cat7),category-8(cat8),category Narrowband Internet of things (NB-IoT) is a low-power wide-area network (LPWAN) radio technology standard developed by 3GPP for cellular network devices and services. The major difference in TDD and FDD is that in TDD system a single frequency is shared in time domain between Uplink and Downlink where as in FDD separate frequencies are used for Uplink and Downlink transmission. 4G comes in different flavours for connected objects. Modulation Techniques in LTE. It is an important metric in the operations management of a company. bis uses existing LTE networks for operation. The LTE standard is intended to provide a downlink speed of 150 Mbps and an uplink speed of 50 Mbps over a wide area. Here are some examples of IoT devices and their specific bandwidth needs. The peak download throughput for LTE Advanced Pro is up to 3 Gbps. Example 1: SNR (SINR) vs Throughput in a LTE Live Network . Mobile devices are categorized as LTE devices if they improve upon third-generation (3G) technology while still falling short of 4G standards. So, the peak speed of a mobile connection is the So, for example, if we think LTE cell will provide 100 Mbps of throughput while in reality can only do 50 Mbps, the operator will be short by 50% of capacity in the access network resulting in poor user experience (e. The throughput values shown above is not an exhaustive list of all the throughput values you can achieve in practice. In mobile networks, the end user throughput is the amount Throughput is a basic KPI on any LTE network. Any one network connection – eg at the LAN layer – has a data rate: the rate at which bits are transmitted. It adds new capabilities to the UMTS networks by introducing a high-speed downlink channel that can be shared between multiple users. It covers LTE Advanced UE category-6(i. Calculation of Throughput in LTE. Cat1. The 5G throughput in the downlink refers to 5G-NB to UE data rate while in the uplink it refers to UE to 5G-NB data rate. It is based on the GSM/EDGE and UMTS/HSPA network technologies, increasing the capacity and speed using a different radio interface together with core network improvements. (LTE only): There is also Table 2 –LTE Categories and Corresponding Throughput Gains. So, in stead of directly jumping into max throughput test, increase the throughput step-by-step and check CPU utilization (e. It employs Orthogonal Frequency Division Multiplexing (OFDM) and Multiple Input Multiple Output (MIMO) antenna systems to increase data throughput and HARQ for LTE Uplink and Downlink. Measuring the throughput only for payload is not enough for operators to closely monitor the health of their LTE network. FDD and TDD in LTE. Factors Affecting Throughput. This Page provides LTE Max (Maximum) users capacity calculator based on CCE. But if heavy congestion occurs, the actual throughput may only be 50 Mbps. 0 In this blog, we will introduce "throughput" in LTE. This article Plus, as 4G/LTE slowly rides off into the sunset, low-band 5G frequencies will no longer need to contend with sharing the digital highway, resulting in better speeds for those who live or wander HSDPA (High-Speed Downlink Packet Access) enhances the downlink throughput in the UMTS networks to improve the download speeds. For the most part, throughput capacity is measured in bits per second, but it can also be measured in data per second. As mentioned KPI is the short form of Key Performance Indicator. 4 MHz compared to 20 MHz for regular LTE, giving a longer range, but less throughput. While power consumption is higher than Low-Power Wide-Area Spectral efficiency is an important consideration for 5G-NR radios, as it was for 4G/LTE: The amount of information that fits in a given channel bandwidth or one just say how efficiently can that piece of spectrum be used to transmit information. As LTE evolves, the length of UE category list gets longer and longer, and the interpretation of the category gets more complicated, you will need to go through many tables listed below to figure out the exact throughput capability of a UE. The measurements in the Internet throughput, often referred to simply as "throughput" or "internet speed," is a measure of the rate at which data is transmitted over an internet connection. bis has been designed to operate using a single antenna while This site is for everything on 4G/LTE. Like LTE Cat 1, LTE Cat1. The fifth generation of mobile networks, 5G, is the successor of LTE and was specified in 3GPP Releases 15 and 16. It became the first Internet of Things (IoT) specific variant of LTE. 4G LTE covers the entire range of download speeds from 3G’s 10 th of Mbps to 4G’s 100 th of Mbps. The throughput by definition is the maximum data rate transmitted by the communication system. 4G LTE-Advanced is a faster version of 4G with typical real-world download speeds of 42Mbps and theoretical limits of 300Mbps. The throughput is 375 kbps uplink and 300 kbps downlink, providing approximately 100 kbps application throughput running IP. It provides an indication of the radio link quality between the device and In lte a UE can have max 11 bearers, 3 SRBs and rest 8 DRBs. The analysis shows the relationship between several widely accepted throughput performance indicators, i. 4G LTE Throughput Calculator and Formula with Step by Step calculation. One very important thing about the Category Table in 36. 1 – This ensures that both FDD LTE and TDD LTE are able to meet the high data throughput requirements placed upon them. the ability to use a SIM card from a network operator on another operator’s network abroad. For example, if you are testing a Category 3 Max throughput case (System BW 20 Mhz, Number of RB = 100), the idea max throughput is LTE, or Long-Term Evolution, is a standard for wireless broadband communication that provides high-speed data transmission for mobile devices. In order to determine physical layer performance, we need to calculate the total physical resources available for different bandwidths of downlink transmission. 4G LTE carrier aggregation basics. The maximum data rate depends on channel bandwidth. 8 we know, that PDCCH (Physical Downlink Control channel) carries The values for throughput shown in the tables are peak connection throughputs not average cell throughput.

The SolarWinds Bandwidth Analyzer Pack is designed to be compatible exclusively with Windows Server versions 2008 R2 SP1, 2012, 2012 R2, and 2016. Many factors can affect throughput; some of these factors include: This site is for everything on 4G/LTE. While LTE is commonly used with 4G, it is not the same as 4G. 306 standard: NR User Equipment (UE) radio access capabilities and uses formula to obtain a 5G NR Throughput data rate in the DL (downlink) and the UL (uplink). For many people working in LTE, one of the most important question would be what is the maximum throughput for a network, device or network operator. In the context of Long-Term Evolution (LTE) wireless communication, the terms "uplink" and "downlink" refer to the two primary directions of data transmission between a user device and the cellular network infrastructure. Today is the start of uplink throughput computation. IxChariot is a product developed by Ixia, which is a side business of the LTE Cat20 is currently (as of February 2023) the most advanced LTE standard available to consumers in th UK. real user bit rate will be a bit lower). What is Ideal/Expected throughput ? One of the most common questions that I have been getting for the past 10 years or so (probably from early HSDPA period and all the way up to now) was 'I have a UE with such and such category, what kind of throughput I need to get from this device ?' (Usually they carry the document like SINR is used a lot by operators, and the LTE industry in general, as it better quantifies the relationship between RF conditions and Throughput. In the theoretical limit it is equal to the Shanon channel capacity C. • The unit of throughput is bits per second or bps. As the bandwidth increases, the amount of data that can be sent at one time increases, resulting in faster communication speed. It's a standard for wireless broadband communication, succeeding 3G. With 4G and LTE, users can enjoy faster internet speeds and improved network reliability. It also offers better signal penetration than 3G, so indoor coverage is much improved. The LTE-M (also known as Cat-M1) is designed for low-power applications requiring medium throughput. This is from one of the most famous rule in communication theory called Shannon's law. –of LTE Cat 11 UE.

LTE also introduces scheduling for shared channel data, HARQ and AMC (Adaptive Modulation and Coding). 213 document. Carrier Aggregation (CA) in 4G LTE networks is a technique that allows them to combine multiple frequency carriers into one to offer larger carrier bandwidths and higher data rates to end-users. In Long-Term Evolution (LTE) networks, PDSCH (Physical Downlink Shared Channel) and PDCCH (Physical Downlink Control Channel) are two essential components of the LTE downlink transmission, each serving a distinct purpose in delivering data and Although signal strength may appear to be adequate, throughput speeds may vary due to dependencies on cellular tower loads; Note that Power parametrs are expressed in dBm, Quality parameters in dB. The main difference between Bit Rate and Throughput in a mobile network is that, Learn 4G-LTE Evolved Packet Core (EPC) Network for Beginners ?. It is defined as the quantity of data being sent/received by unit of time. . Unlike HSPA, LTE's E-UTRA is an entirely new air interface system. In reality though, due to interference, the throughput won't be exactly doubled, 4G LTE A. LTE uses a combination of technologies to achieve high-speed data transmission. LTE Cat 1 standard was introduced in the 3GPP Release (Rel) 8 in 2008. 211 Chapter 6. TDD LTE does not require paired spectrum as both uplink and downlink communication happens through the same channel. Additionally, LTE-M, as a natural extension of 4G LTE, benefits from out-of-the box roaming, i. Typical file sizes used in our calculations: 2MB for a webpage, 10KB for a basic e-mail, 2MB for a high-quality photograph, 5MB for a music track and 30MB for a typical application download. Example 1 > PHY throughput and RLC Throughput in a drive test . It is often referred to as 4G (fourth generation) technology, succeeding 3G (third Increased Data Speeds: LTE significantly boosts data transfer speeds, providing higher throughput compared to 3G networks. Personally to me, RLC layer is one of the trickest area to understand in very detail. It enables all singular device use case - even for image or video content - but may not be Explore popular LTE IoT standards: LTE Cat 1, LTE Cat 1bis, LTE-M, and NB-IoT.

It improves on those standards' capacity and speed by using a different radio interface and core network improvements. An LTE Rel. 95G. The calculation is based on CRC (Cyclic Redundancy Check) evaluation which is used for inspection the transport blocks at receiver side. Start Learning ! LTE (4G) Network Architecture. For this reason, LTE may also be called 3. 0 Mbit/s and an uplink data rate of 51. Supports TDD, FDD and SDL, Carrier aggregation and MIMO LTE throughput calculator Introduction The post presents the simplest way how to calculate LTE throughput. From 3GPP 36. Simply put, the code rate can be defined as the ratio of the data rate that is allocated for a subframe and the maximum data rate that ideally can be allocated in the subframe. In some LANs (eg Wi-Fi) the data rate can vary with time. On the surface bandwidth and throughput appear to be similar but they couldn’t be further apart in practice. Throughput ©3G4G Throughput is the actual rate that information is transferred. The main difference between the two standards is that LTE. Throughput is measured at Layer 1/2 or even at application layer. Specifically, devices use LTE if their mobile data download speed is LTE Cat 11 (LTE Category 11) is an LTE user equipment (UE) category that defines the performance and specifications – such as data rate, power, type of modulation, bandwidth, etc. The analysis shows several important performance indicators affecting 4T4R performance, such as RRC_connected user, PRB utilization, cell throughput, user throughput, and RI ratio, how these indicators are related to modulation and coding scheme The different test cases of LTE KPI are mentioned for each of the KPI categories. Difference Between Latency and Throughput: In a computer network computers are connected using different types of devices like routers switches, etc that form the network. Throughput refers to the overall effective transmission rate, taking into account things like transmission overhead, protocol inefficiencies and perhaps even competing traffic. Understanding PDSCH (Physical Downlink Shared Channel) and PDCCH (Physical Downlink Control Channel) in LTE. Networks on LTE bands 1, 3 (LTE-FDD) are suitable for roaming in ITU Regions 1, 3 and partially Region 2 (e. It takes advantage of radio waves which deliver wider coverage when compared to microwaves in 3G and WiMAX. Calculate the maxium theoretical throughput of a specified LTE Configuration. UE Category for PHY layer throughput . Similarly, the lower the UE Category, the lower the device’s data throughput capability. There will be two models: a North American model (µ/ý X” ê^zm4€JÑT= —Edë'QE 9n»Þý$‰$E’”(Rð þ i†©kK áAÇ -ç(¶ËqXÓ}òù È ° ŠËP/ ]·ìüliDÄC¼ÐØõÍòUÅ0 BQUTò𠨥Oõxø This site is for everything on 4G/LTE. For example, in FDD, when the bandwidth doubles, the communication speed (throughput) also doubles. In LTE, usually they use multiple Antenna for downlink (at least from Category 3 UE and higher), meaning that eNode (Network) has use multiple Tx Antenna and UE use multiple Rx antenna. MIMO Modes in LTE: LTE supports RSRQ 3GPP DefinitionReference Signal Received Quality (RSRQ) is defined as the ratio N×RSRP/(E-UTRA carrier RSSI), where N is the number of RB’s of the E-UTRA carrier RSSI measurement bandwidth. emnify IoT SuperNetwork. These events are essential for determining when to initiate handover procedures in LTE networks, ensuring smooth and seamless transitions between cells or different radio access technologies. LTE Cat 11 UEs are based on LTE Advanced (LTE-A) technology with support for a downlink data rate of 603. Multiple LTE carriers each with Bandwidth of 20MHZ can be transmitted in parallel to and from from the same UE. 10 UE that is CA-enabled would achieve higher user throughput than an LTE Rel.
