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 WiMAX technology and how it works?
WiMAX delivers ‘last-mile’ wireless broadband Internet access. WiMAX is an alternative to wired broadband, such as DSL and cable modem, and according to the forum, “provides fixed, nomadic, portable and, soon, mobile wireless broadband connectivity without the need for direct line-of-sight with a base station.”
What is the role of ASN and ASN Gateway in WiMAX?
Access service networks (ASN) provide a means to connect mobile subscribers using OFDMA air link to IP backbone with session continuity. ASN comprises base stations (BS) and access gateways named ASN-GW. The interface between the ASN and mobile subscriber is through BS with IEEE 802.16e-2005 (IEEE 80w.
How ASN is different from CSN in WiMAX?
An ASN can consist of one or more base stations (BSs) and access service network gateways (ASN-GWs), which are all managed by a single network access provider (NAP). The CSN, on the other hand, is the entity which provides all the IP core network (CN) functionalities to the WiMAX radio equipment residing in ASNs.
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].
What is the difference between WiFi and WiMAX?
WiMax uses licensed or unlicensed spectrum to deliver connection to network. 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 connection can transmit upto 54 mbps. | WiMax connection can transmit upto 70 mbps. |
What is ASN gateway?
The ASN GW is the key to the IP mobility scheme. It provides the termination of the mobility function across base-stations and the foreign agent function. The ASN GW maps the radio bearer to the IP network. It works with the CSN and the policy servers to control policy on behalf of the user.
What is access service network?
An access network is a type of telecommunications network which connects subscribers to their immediate service provider. It is contrasted with the core network, which connects local providers to one another.
What is network Reference Model?
In computer networks, reference models give a conceptual framework that standardizes communication between heterogeneous networks. The two popular reference models are − OSI Model. TCP/IP Protocol Suite.
