1. FD-LTE Band 3 operates on the 1800 MHz frequency band, which encompasses the range of 1710-1785 MHz for uplink and 1805-1880 MHz for downlink.2. This band is widely used internationally but may experience interference from GSM systems, which also utilize parts of the frequenc...
在LTE中,频段是用来划分不同的频率范围以及对应的频点。 LTE的频段主要分为FDD(Frequency Division Duplex)和TDD(Time Division Duplex)两种模式。FDD模式中,上行频段与下行频段是分开的,而TDD模式中,上行和下行共用同一频段。 LTE的频段被分为多个频带,每个频带对应着不同的频率范围和频点。每个频段都有其特定的用途...
LTE系统引入了OFDM(Orthogonal Frequency Division Multiplexing,正交频分复用)和MIMO(Multi-Input & Multi-Output,多输入多输出)等关键技术,显著增加了频谱效率和数据传输速率(20M带宽2X2MIMO在64QAM情况下,理论下行最大传输速率为201Mbps,除去信令开销后大概为150Mbps,但根据实际组网以及终端能力限制,一般认为下行峰值速...
