What type of network is used in WiMAX?

WiMAX is a long range system, covering many kilometres, that uses licensed or unlicensed spectrum to deliver connection to a network, in most cases the Internet. Wi-Fi uses the 2.4 GHz and 5 GHz radio frequency bands to provide access to a local network. Wi-Fi is far more popular in end-user devices.

What is the principle behind WiMAX communication?

Mobile WiMAX uses Orthogonal frequency division multiple access (OFDM) as a multiple-access technique, whereby different users can be allocated different subsets of the OFDM tones.

What are the two types of connections supported by WiMAX?

WiMAX supports both fixed and mobile users, based on IEEE 802.16-2004 [802.16, 2004] and IEEE 802.16e-2005 [802.16, 2005] standards, respectively. IEEE 802.16 system is connection oriented and provides Quality of Service (QoS) assurances through service flows and scheduling services.

What is the advantage of IEEE 802.20 over IEEE 802.16 E?

“They do have some minor differences, but they both are aimed to serve similar users.” Essentially, 802.16e is looking at the mobile user walking around with a PDA or laptop, while 802.20 will address high-speed mobility issues, he said. One key difference will be the manner in which the two are deployed.

What is an IEEE 802.16 network?

IEEE 802.16 also known as WiMAX (Worldwide Interoperability for Microwave access Networks) has been designed to provide wireless and wired broadband access with QoS guarantees in Metropolitan area networks [1].

Which one of the modulation scheme is supported by WiMAX?

Explanation: WiMAX supports a variety of modulation schemes such as binary phase shift keying modulation, quadrature phase shift keying modulation, and quadrature amplitude modulation and allows for the scheme to change on a burst-by-burst basis per link, depending on channel conditions.

How does WiMAX Internet access work?

An Internet service provider sets up a WiMAX base station 10 miles from your home. You would buy a WiMAX-enabled computer or upgrade your old computer to add WiMAX capability. You would receive a special encryption code that would give you access to the base station.

Does WiMax support voice and video?

WiMAX can support voice and video as well as Internet data. 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.

How do I limit broadcast packets on my switch?

Storm control and equivalent protocols allow you to rate-limit broadcast packets. If your switch has such a mechanism, turn it on. Ensure IP-directed broadcasts are disabled on your Layer 3 devices. There’s little to no reason why you’d want broadcast packets coming in from the internet going to a private address space.

What is a broadcast packet and how does it work?

A broadcast packet consists of the following Layer 2 and Layer 3 destination header: The Dynamic Host Configuration Protocol (DHCP) is the most common way for a networked host to obtain an IP address from a network controller. Think about when you take your laptop to a coffee shop and hop on WiFi.
