这篇文章介绍了基于来自商业部署的频带3中的第三代合作伙伴计划（3GPP）版本8LTE网络的现场测试结果的长期演进（LTE）蜂窝系统的实际性能分析（即，1，800 MHz，有时称为LTE 1，800 MHz），信道带宽为20 MHz。所呈现的分析展示了移动性条件下的下行链路（DL）和上行链路（UL）吞吐量以及LTE系统的其他方面，诸如链路预算、小区覆盖、频谱效率和切换性能。LTE的关键特征，例如多输入多输出（MIMO）和高阶调制[即，64正交幅度调制（QAM）]在不同的射频（RF）条件下进行评估。在LTE和3GPP版本8演进的高速分组接入（HSPA+）与基于具有10-MHz带宽的通用移动的电信系统（UMTS）2，100-MHz商用网络的双小区高速DL分组接入（DC-HSDPA）特征之间呈现比较（即，2 x 5-MHz相邻载波）。本文提出的LTE网络性能分析以及与HSPA+网络的比较可以用来对LTE进行基准测试
his article introduces a practical performance analysis of the long-term evolution (LTE) cellular system based on field test results from a commercially deployed Third-Generation Partnership Project's (3GPP's) Release 8 LTE network in Band-3 (i.e., 1,800 MHz, sometimes termed LTE1,800 MHz) with 20-MHz channel bandwidth. The presented analysis demonstrates the downlink (DL) and uplink (UL) throughputs in mobility conditions in addition to other aspects of the LTE system such as link budget, cell coverage, spectral efficiency, and handover performance. LTE's key features such as multiple-input, multiple-output (MIMO) and higher-order modulation [i.e., 64 quadrature amplitude modulation (QAM)] are assessed in different radio frequency (RF) conditions. A comparison is presented between LTE and 3GPP Release 8 evolution of high-speed packet access (HSPA+) with a dual-cell high-speed DL packet access (DC-HSDPA) feature based on the universal mobile telecommunications system (UMTS) 2,100-MHz commercial network with 10-MHz bandwidth (i.e., 2 x 5-MHz adjacent carriers). The presented LTE network performance analysis and the comparison with the HSPA+ network can be used to benchmark the LTE
