What is the standard for WiMAX?

What is the standard for WiMAX?

WiMAX (a term originally developed as an abbreviation for Worldwide Interoperability for Microwave Access), is a revolutionary communications technology based on the IEEE 802.16 standard. It provides for mobile wireless links, at broadband speeds, with a new and growing family of internet-connected devices.

What are the main key aspects of WiMAX security?

WiMAX – Security Functions

• Support for Privacy. User data is encrypted using cryptographic schemes of proven robustness to provide privacy.
• Device/user Authentication.
• Flexible Key-management Protocol.
• Protection of Control Messages.
• Support for Fast Handover.

What is WiMAX architecture?

The WiMAX architecture developed by the WiMAX form supports is a unified network architecture to support fixed, nomadic and mobile operation. The WiMAX network architecture is based upon an all-IP model. The WiMAX network architecture comprises three major elements or areas.

How secure is WiMAX?

WiMAX has security vulnerabilities in both PHY and MAC layers, exposing to various classes of wireless attack including interception, fabrication, modification, and replay attacks [Narsreldin08]. Some vulnerabilities of WiMAX originate from flaws of IEEE 802.16 on which WiMAX is based.

Where is WiMAX normally used Class 10?

WiMAX is a wireless communications standard designed for creating metropolitan area networks (MANs). It is similar to the Wi-Fi standard, but supports a far greater range of coverage. While a Wi-Fi signal can cover a radius of several hundred feet, a fixed WiMAX station can cover a range of up to 30 miles.

What is the IEEE 802 standards for local wireless networks?

IEEE 802 wireless standards. IEEE 802 is a collection of networking standards that cover the physical and data-link layer specifications for technologies such as Ethernet and wireless. These specifications apply to local area networks (LAN) and metropolitan area networks (MAN).

Which of the following frequencies is not used in WiMAX for communication?

Explanation: The 2.4GHz ISM frequency band is used for personal area network technologies such as Bluetooth and hence is not suitable for WiMAX which is mostly used for Metropolitan Area Networks.

What are the basic components of WiMAX?

The system has two main components: A WiMax tower and a WiMax receiver. Like Wi-Fi, WiMax can connect directly to the Internet by sending a signal from a WiMax tower to a WiMax-enabled computer via a wired connection.

What are the WiMAX protocols used for?

WiMax developed to provide wireless broadband access to buildings, either in competition to existing wired networks or alone in currently unserved rural or thinly populated areas. It can also be used to connect WLAN hotspots to the Internet. WiMAX is also intended to provide broadband connectivity to mobile devices.

How is WiMAX different from WiFi in the context of security concerns?

WiFi is for LAN (Local Area Network) applications. WiMax is for MAN (Metropolitan Area Network) applications. WiFi does not guarantee any Quality of Service (Qos). WiMax guarantee Quality of Service (Qos).

Which of the following encryption techniques are supported by WiMAX to provide high security *?

Since DES is no more secure enough, AES is recommended in WiMAX with many supported modes: CCM-Mode and ECB-Mode (in IEEE 802.16-2004), CBC-Mode, CTR-Mode, AES-Key-Wrap.

Which is faster wifi or WiMAX?

With regards to Speed, Broadband Wifi 802.11N is actually faster than Wimax 802.16e. For the Wimax Standard 802.16e, they are talking about 70 Mbps. So Wimax is actually slower than Broadband Wifi. On the other hand Wimax 802.16e is ready today with a range of 40 Miles.

IEEE 802.16: WiMAX Overview, WiMAX Architecture  wireless newcomer, WiMAX always has been viewed as Abstract—WiMax, the Worldwide Interoperability for Microwave Access is a new technology dealing with provision of data over long distance using wireless communication method in many different ways.

Is WiMAX an alternative broadband?

What is conconcept WiMAX?

Concept WiMAX (Worldwide Interoperability for Microwave Access) is a connection-orientedwide area network [1].

What is IEEE WirelessMAN air interface?

The IEEE 802.16, the Air Interface for Fixed Broadband Wireless Access Systems, also known as the IEEE WirelessMAN air interface, is an emerging suite of standards for fixed, portable and mobile BWA in MAN.
