1. 全球微波接入互通(WiMax):
全球微波接入互操作性 (WiMax) 是指基于 IEEE 802.16 的无线通信标准,它是一种更新的点对多点无线网络技术,意味着它指定了不同无线设备如何在广域中通过空中/网络进行通信。

两种类型的 WiMax 规范:

  • 固定无线 WiMax:在此固定无线 WiMax 规范中,一个人从家里或其他永久位置的台式计算机访问 Internet。
  • 移动无线 Wimax :在此移动无线 WiMax 规范中,一个人使用移动计算机和智能手机等移动设备访问 WiMax 网络。

2.长期演进(LTE):
长期演进 (LTE) 是指实现 4G 速度所遵循的路径。它是无线数据传输的标准,意味着它位于 4G 之后,4G 在全球范围内用于通过蜂窝网络传输数据。因此,更快的数据传输成为可能,例如,与以前的 3G 技术相比,现在下载喜爱的音乐、网站和视频的速度确实快得多。这是为蜂窝移动通信系统提供高性能空中接口的第四代 (4G) 的最后一步。所以在 2G 之前,3G 就在那里,而这种 LTE 以 4G 的形式销售。

WiMax和LTE的区别:

S.No. WIMAX LTE
01. Worldwide Interoperability for Microwave Access in short referred as WiMax. Long Term Evolution in short it is referred as LTE.
02. WiMax is a wireless communication standard based on IEEE 802.16 and it is a newer technology for point to multipoint wireless networking means it specifies how wireless devices communicate over the air in a wide area. LTE is not a technology rather it is a path followed to achieve 4G speed and a standard for wireless data transmission means it is behind 4G which is used worldwide for transferring data over cellular networks.
03. Its network architecture is Flat and IP based, Access Service Network Gateway (ASN-GW). Its network architecture is Very flat and IP based, Evolved Node B (ENode B).
04. It provides mobility with target up to 120km/h. It provides mobility with target up to 350km/h.
05. The subcarrier spacing can be variable due to which capacity can be varied. Subcarrier spacing constant at 15Khz.
06. In this due to high channel utilization, processing that much information requires 1000 point Fast Fourier Transform (FFT). In this due to organization of data into smaller chunks makes it process the information by lower point Fast Fourier Transform (FFT) like 16 point FFT.
07. Duplex mode mostly focus on Time Division Duplex (TDD). Duplex mode mostly focus on Frequency Division Duplex (FDD).
08. It mostly provides fixed bandwidth. It mostly provides flexible bandwidth.
