Uses of WiMAX
- Providing portable mobile broadband connectivity across cities and countries through various devices.
- Providing a wireless alternative to cable and digital subscriber line (DSL) for "last mile" broadband access.
- Providing data, telecommunications (VoIP) and IPTV services (triple play).
WiMAX is a telecommunication and mobie technology used for broadcasting of wireless data by the use of a number of transmission methods. WiMAX stands for Worldwide Interoperability for Microwave Access offering internet access point to point or point to multipoint or path. The WiMAX network is just like a cell phone.
Go to the nearest BSNL exchange with relevant documents (Address proof, Pasport Size Photo and an ID proof), you will get the new connection within few days. Now you can register for a new WiMax connection through BSNL at doorstep online portal also.
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. Wifi is defined under IEEE 802.11x standards where x stands for various WiFi versions.
Range. Wi-Fi typically provides local network access for a few hundred feet with the speed of up to 54 Mbps, a single WiMAX antenna is expected to have a range of up to 40 miles with the speed of 70 Mbps or more. As such, WiMAX can bring the underlying Internet connection needed to service local Wi-Fi networks.
WIFI: Wireless Fidelity
WIFI also Spelled as Wi-Fi is a local area wireless technology. It allows an electronic device to transfer data or connect to the internet using ISM radio bands. It is an underlying technology of wireless local area network (WLAN).5G: As much about fixed as mobile
5G has been just as much about fixed as it is about mobile. Sure, there are fixed wireless access networks based on LTE, but that has never been the big push for the LTE ecosystem. Both WiMAX and 5G came with talk about new business models.According to some estimates, the current subscriber equipment costs about $300, about two times (roughly speaking) the price of WiFi, cable and DSL customer premise equipment. In-Stat, estimates that it would take a total of $3 billion to set-up a national WiMAX network in the US.
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.
WiMAX - Salient Features
- Two Type of Services. WiMAX can provide two forms of wireless service −
- OFDM-based Physical Layer.
- Very High Peak Data Rates.
- Scalable Bandwidth and Data Rate Support.
- Adaptive Modulation and Coding (AMC)
- Link-layer Retransmissions.
- Support for TDD and FDD.
- WiMAX Uses OFDM.
One difference between LTE and WiMAX is that they function on different frequencies, making their deployment slightly different. WiMAX is made to work with new deployments, while LTE is made for existing mobile and broadband deployments. WiMAX is meant more for new deployments and networks.
802.11 and 802.11x refers to a family of specifications developed by the IEEE for wireless LAN (WLAN) technology. 802.11 — applies to wireless LANs and provides 1 or 2 Mbps transmission in the 2.4 GHz band using either frequency hopping spread spectrum (FHSS) or direct sequence spread spectrum (DSSS).
The world's first publicly available LTE service was opened in the two Scandinavian capitals, Stockholm (Ericsson and Nokia Siemens Networks systems) and Oslo (a Huawei system) on December 14, 2009, and branded 4G. The user terminals were manufactured by Samsung.
WiMAX (Worldwide Interoperability for Microwave Access) technology, can provide a speed of up to 37 mbps. It is being deployed in Kerala with 900 BTS (Base Transmitting Stations) to cover the entire state, Principal General Manager, BSNL, Ernakulam, E M Abraham said.
WiMAX Forum™ was formed by equipment and component suppliers to support the IEEE 802.16 BWA system by helping to ensure the compatibility and interoperability of BWA equipment, which will lead to lower cost through chip-level implementation.
3G follows a pattern of G's that the ITU started in the early 1990s. The pattern is a wireless initiative called the International Mobile Communications 2000. 3G, therefore, comes just after 2G and 2.5G, the second-generation technologies. 2G technologies include, among others, the Global System for Mobile.
Access Point (AP) – The AP is a wireless LAN transceiver or “base station” that can connect one or many wireless devices simultaneously to the Internet. Wi-Fi cards – They accept the wireless signal and relay information. They can be internal and external.
Sprint just made it official that they will be rolling out 4G LTE, and basically slowly backing away from their current 4G network, WiMax.
HSPA+, or Evolved High-Speed Packet Access.
HSPA or HSPA+ is a technical standard for wireless, broadband telecommunication. HSPA+ enhances the widely used WCDMA based 3G networks with higher speeds for the end user that are comparable to the newer LTE networks.The IEEE 802.16 mesh standard uses a combination of a 16-bit mesh node identifier (node ID) and a 16-bit connection identifier (CID) to identify the source and destination of every transmission. The CID in mesh mode is a combination of an 8-bit link ID and an 8-bit QoS description for the connection.
wireless local area network
The Internet is a global network of billions of computers and other electronic devices. With the Internet, it's possible to access almost any information, communicate with anyone else in the world, and do much more. You can do all of this by connecting a computer to the Internet, which is also called going online.
