Common questions

Does WiMAX use OFDM?

Does WiMAX use OFDM?

The WiMax (Worldwide Interoperability for Microwave Access) is a technology in broadband wireless access, which employs OFDM (Orthogonal Frequency Division Multiplexing) as an alternative transmission to enable high speed data in communication system.

What is WiMAX and LTE?

To start with, the basic technical difference comes from the bandwidth LTE-A uses upto 100 MHz while WiMAX (802.16m) has max. 40 MHz bandwidth to its disposal. Both are based on flat-ip architecture. LTE-A can handle mobility speeds upto 450-500 Km/Hr (max), while 802.16m can support speeds upto 120 Km/hr.

Which technologies are used to schedule WiMAX uplink and downlink communication?

1) OFDMA is applied in both the uplink and downlink. 2) Both time division multiple access (TDMA) and FDMA are supported for both the uplink and downlink. 3) MIMO technology is introduced to improve system performance.

Why is LTE more acceptable than WiMAX now?

But if there were any 802.16 networks it is possible to switch, if both 802.16 networks are compatible. WiMAX is more suitable for laptops since it is less mobility, but for cellular devices LTE is more suitable, since it moves a lot and with its extensive coverage there are no problems even with the slower connection.

Why was OFDM used in WiMAX?

OFDM is a spectrally efficient version of multicarrier modulation, where the subcarriers are selected such that they are all orthogonal to one another over the symbol duration, thereby avoiding the need to have non-overlapping subcarrier channels to eliminate inter-carrier interference.

Where is WiMAX normally used Class 10?

It is a long range system covering many kilometres and is typically used where DSL or Cable Internet Access cannot be used.

Which is faster WiMAX or 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….Difference between WiMax and LTE :

08. It mostly provides fixed bandwidth. It mostly provides flexible bandwidth.

Is WiMAX better than WiFi?

WiMax handle a larger inter-operable network. WiMax can be used to provide internet services such as mobile data and WiFi spots….Difference between WiFi and WiMax:

WiFi WiMax
WiFi is short range technology. WiMax is long range technology.
WiFi connection can transmit upto 54 mbps. WiMax connection can transmit upto 70 mbps.

What is WiMAX how it works?

WiMAX delivers ‘last-mile’ wireless broadband Internet access. Compared to the more prevalent Wi-Fi (IEEE 802.11), whose coverage maxes out around 300 feet, WiMAX will, in theory, transmit a high-speed signal for 30 miles in every direction from a fixed station.

Can WiMAX be used as WiFi?

WiMax can be used to provide internet services such as mobile data and WiFi spots.

Which is better LTE or WiMAX?

Is WiMAX the same as 4G?

Along with a competing standard called “LTE,” WiMax, short for Worldwide Interoperability for Microwave Access, represents 4G or the “fourth generation” of wireless Internet. The new technology is similar to Wi-Fi in that it allows users to connect to the Internet without wires.

Is there a WiFi to LTE handover?

This page covers LTE to WLAN (WiFi) handover.It also mentions WLAN (WiFi) to LTE handover with message flow diagram. Due to huge increase of data traffic, telecom operators are adopting technologies like LTE, LTE advanced. Though it is not sufficient to address rise in demand.

How does PDN Gateway help in LTE handover?

Hence PDN gateway helps in handover between the two systems. • Assume that UE is connected with LTE network. • UE detects existing WLAN APs (wifi hotspots), it selects the one which can provide connectivity to its mobile subscriber.

What does intra E UTRAN mean in LTE handover?

LTE Handovers – Intra E-UTRAN Handover. Posted on 10. Intra E-UTRAN Handover is used to hand over a UE from a source eNodeB to a target eNodeB using X2 when the MME is unchanged.
