1. Worldwide Interoperability for Microwave Access (WiMax) :
Worldwide Interoperability for Microwave Access (WiMax) refers to 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 different wireless devices communicate over the air/network in a wide area.
Two types of WiMax specification :
- Fixed wireless WiMax : In this Fixed Wireless WiMax specification, a person accesses the Internet from a desktop computer at home or other permanent location.
- Mobile wireless Wimax : In this Mobile Wireless WiMax specification, a person access the WiMax network with mobile computers and mobile devices such as smart phones.
2. Long Term Evolution (LTE) :
Long Term Evolution (LTE) refers to a a path followed to achieve 4G speed. It is a standard for wireless data transmission means it is behind 4G which is used worldwide for transferring data over cellular networks. Due to this, faster data transmission is possible for example, now downloading favorite music, websites, and video really much faster as compared to previous 3G technology. It is the last step towards Fourth Generation (4G) which provides a high performance air interface for cellular mobile communication systems. So before 2G, 3G were there and this LTE marketed as 4G.
Difference between WiMax and 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.|
