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. |
