What is WiMAX

Published by:

With the presence of Wireless access in cities, businesses of different kinds have revolutionized their set up and service status. Yet there were some remote areas where customers were caught inaccessible to internet or a network. To meet the demand of present time where immobility has no concept the idea of WiMAX is quite appealing. WiMAX is a technology comes up with multiple solutions.

WiMAX Specifications
Whereas Wi-Fi specification is IEEE 802.11b there WiMAX is introduced as IEEE 802.16 which has totally changed the horizon of computer world. There is no boundaries to get connect anywhere, anytime. Hurdles are crossed over and WiMAX is now eligible to penetrate through for the connectivity in all sorts of conditions. Previously, Fixed WiMAX was introduced but lasted mobile WiMAX has replaced its market quickly as its features are more appealing and beneficial as compared to fixed WiMAX.

WiMAX Bandwidth
WiMAX comes up with a greater bandwidth support. To gain the instant speed FFT has been scaled for the bandwidth into channel form. It is to be considered that the channels are of equal space so that spectrum should be broader. This is known as a wide channel while there is narrow channels as well which offer less expenditure.

WiMAX Range

The specification (802.16e) latest standard of WiMAX offers more than 70 GHz range. It is providing scalable orthogonal frequency-division multiple accesses and is showing much better performance than fixed standard.

WiMAX Features

If we consider the features of WiMAX, it has nearly taken place of all the mediums used for connectivity and display. With the introduction of this new specification, the use of internet and the coordination through networking has excelled the efficiency of users.

Mobility

Mobility is the first benefit seen when we come from DSL or any other wired communications. The removal of restrictions or limitations gives the ease of connectivity in any way, no matter where the user stands. This mobility is not available in an enclosed premise of a specific place. Wimax range is wider now and accessible under the cities or across the countries.

Access

WiMAX offers connectivity is fulfill the meaning of the phrase last mile fully well. It is supporting wide range to access the frequency in the near surrounding to overlap it to connect. This feature is the most important one as it supports the service in the remote rural areas.

Versatility

It is better to say that WiMAX is a versatile mobile broadband. It is not only supporting the wireless connectivity but also a large amount of data is transferred through it. Different services like Voice over IP and especially Triple play is possible by using the WiMAX only. It stands alone as powerful giant to meet the criteria for all those services which are obtained by using various equipments. WiMAX replaces all those gadgets and offers its services with full confidence.

Connectivity

Once deployed the WiMAX then forget the disconnection. WiMAX will become responsible and make you forget about problems related to internet or network. It is fulfilling the responsibility through different medium available in the market called subscriber units like, cell phone, Net books, iPods, etc. Now-a-days, gaming consoles are also supported by this WiMAX service. This services is accessible in a multiple ways by using Wi-Fi access point, Ethernet ports are also supporting the WiMAX connectivity, while telephone jacks are convenient way to access this WiMAX service.

Limitations

After reading so many plus points, one will think about it as a best option ever had. However there are certain limitations attached to Wimax which cannot be negligible.

Speed / Distance

Speed is inversely proportional to distance as when go away from the access point you will lose the speed. The greater the distance the lesser the speed will be in Wimax network.

Quality / Bandwidth

Performance is dependent on the available bandwidth in Wimax network. If the bandwidth is divided into different users active at the same time, surely you are going to lose the quality of service.

 

WiMAX Vs WiBro -Comparison of WiMAX & WiBro

Published by:

WiBro is a new wireless technology developed to consent user to watch TV on their cell phones. South Korea telecom industry developed IEEE 802.16e as international standard. Wibro implement TDD for duplexing. It uses OFDM for manifold access with 8.75 MHz as a channel bandwidth. WiBro was developed to defeat the data rate restrictions of cell phones as CDMA. WiBro also used to adjoin mobility to broadband Internet access like ADSL. WiBro wireless technology is still in the developmental process and when it improves it may call for an entirely different standard on the whole with a finally different name.

Differnce between Wimax vs Wibro

  • Wibro has been in the workings for around the same time as from WiMax. This wireless technology introduced as a mobile broadband access in Korea as a mobile broadband but since it is based on Wimax and only Korean deploy Wibro.
  • The base station of Wibro provides data 30 Mbits to 50 Mbits per carrier and conceal 1 to 5km radius permit for the use of moveable internet usage for moving devices it provide 120 km/h (74.5 miles/h).While the coverage range of wimax is 70 kilometers along 4km radius.
  • The technology of Wibro also offers high quality services such as inclusion of video streaming content and loss responsive data in consistent manner and it is a great advantage over fixed wimax technology.
  • There are many telecom industries trying to commercialize the WiBro such as TI, TVA, PORTUS, and Arialink. WiBro is fairly exact in its necessities from spectrum use to equipment design. While Wimax leaves much of this up to the equipment supplier while provided that sufficient element to make sure interoperability among designs.
  • WiMax is calm of two versions in which one is stationary and second is mobile. Commonly WiMax is for public in fixed locations while Wibro and Mobile specifications are mobility.
  • Wibro facilitate the user to get access to internet doesn’t matter traveling at the speed of up to 120 kilometers while WiMax at present lacks such capability.
  • WiMax is being sponsored and developed in India by Intel while Samsung Electronics is the foremost developer of Wibro.
  • Wibro is better than Wimax because the Wimax technology still facing compatibility problems while Wibro is already broadcast data on fast-moving equipment at 60km/h and through.
  • The broadcasting of data between two bases station in possible in Wibro. WiMAX network with 802.16 standards allows only a lot of users on the standard and if any user trying to use the connection it will immediately cut off any additional users.
  • Wibro network technology is very alike Wimax the transmission speed of both technologies are the same, but the difference is that a Wibro can mark out a receiver that is stirring from one location to another location, while Wimax does not propose this because it requires a stationary antenna for the purpose of receiving signal.
  • Wimax is a telecommunication technology based on IEEE 802.16 standards offering sending and receiving of wireless data over long distance in a different manners from point to point or point to multipoint, while WiBro is a wireless broadband technology being developed and it is the Korean service name for IEEE 802.16e.
  • WiBro design offer very high speed which is up to 74MPH while Wimax offer connectivity over 31 miles. Wibro provide exact figure which is 74 MPH and Wimax provide best connectivity only in specified region or if user exist very near to tower.
  • The WiMax technology is well recognized than WiBro but it has become more important and in the future WiBro wireless technology will be resolute more thoroughly.

What is WiMAX Technology

Published by:

Wimax stands for Worldwide Interoperability for Microwave Access. Wimax technology is a telecommunications technology that offers transmission of wireless data via a number of transmission methods; such as portable or fully mobile internet access via point to multipoints links. The Wimax technology offers around 72 Mega Bits per second without any need for the cable infrastructure. Wimax technology is based on Standard that is IEEE 802.16, it usually also called as Broadband Wireless Access. WiMAX Forum created the name for Wimax technology that was formed in Mid June 2001 to encourage compliance and interoperability of the Wimax IEEE 802.16 standard. Wimax technology is actually based on the standards that making the possibility to delivery last mile broadband access as a substitute to conventional cable and DSL lines.

Wimax (802.16) technology often misinterpreted by the people by the names of mobile WiMAX, 802.16d, fixed WiMAX and 802.16e. Actually 802.16-2004 or 802.16d is developed by the third party as a standard and it is also referred to called as Fixed WiMAX because this standard is lacking behind just because of the non-mobility feature that’s why it’s often called as Fixed WiMAX. During the maturity period of Wimax (802.16) technology some of the amendments were made to the above mentioned 802.16d and they referred this amending standard as 802.16e. 802.16e introduced mobility and some other features amongst other standards and is also known as Mobile WiMAX.

Less than one out of five people of the developed world and an even smaller, little percentage of people across the world have broadband access today. Existing technologies such as Digital Subscriber Line (DSL), cable, and fixed wireless are overwhelmed by expensive installs, problems with loop lengths, upstream upgrade issues, line-of-sight restrictions, and poor scalability.

Wimax Technology

Wimax Technology

Wimax (802.16) is the next stage to a broadband as well as a wireless world, extending broadband wireless access to new locations and over longer distances, as well as considerably reducing the cost of bringing broadband to new areas. Wimax (802.16) technology offers greater range and bandwidth than the other available or forthcoming broadband wireless technologies such as Wireless Fidelity (Wi-Fi) and Ultra-wideband (UWB) family of standards. It provides a wireless alternative to wired backhaul and last mile deployments that use Data Over Cable Service Interface Specification (DOGS1S) cable modems, Digital Subscriber Line technologies (DSL), T-carrier and E-carrier (Tx/Ex) systems, and Optical Carrier Level (OC-x) technologies. (Jiffy Networks, 2006)

The general initiative of metropolitan area wireless networking, as envisioned with 802.16, begins with what is called fixed wireless. A backbone of base stations is connected to a public network, and each base station carries hundreds of fixed subscriber stations, which can be both public hot spots and fire-walled enterprise networks. Later in the development cycle of 802.16e, Wimax (802.16) is expected to encourage mobile wireless technology specifically wireless transmissions directly to mobile end users, This will be similar in function to the General Packet Radio Service (GPRS) and the one times Radio Transmission Technology (RTT) offered by mobile phone companies.

New organizations as well as individuals are increasingly adopting broadband, whereas those already using broadband are becoming dependent on it and are demanding better services with added benefits. To support this exceptional new demand, Wimax (802.16) has emerged as a feasible solution, because of its inherent features that holds great promise for the future of wireless communications. (Teri Robinson, 2005)

There has been a lot of excitement about Wimax (802.16) and the impact that this standards based wireless network technology will have on the broadband access market. All this hype has generated great expectations, and the industry has responded with exceptional aggression and commitment toward taking broadband to the next level with Wimax (802.16).

How WiMAX Works

The backhaul of the Wimax (802.16) is based on the typical connection to the public wireless networks by using optical fibre, microwave link, cable or any other high speed connectivity. In few cases such as mesh networks, Point-to-Multi-Point (PMP) connectivity is also used as a backhaul. Ideally, Wimax (802.16) should use Point-to-Point antennas as a backhaul to join subscriber sites to each other and to base stations across long distance.

A wimax base station serves subscriber stations using Non-Line-of-Sight (NLOS) or LOS Point-to-Multi-Point connectivity; and this connection is referred to as the last mile communication. Ideally, Wimax (802.16) should use NLOS Point-to-Multi-Point antennas to connect residential or business subscribers to the Wimax Base Station (BS). A Subscriber Station (Wimax CPE) typically serves a building using wired or wireless LAN. (Steven J. Vaughan-Nichols, June 2004)

WiMAX standards & Specifications

Published by:

Many standards are often referred to as Wimax (802.16)or broadband access standards just like Wi-Fi. Technically, Wimax supports IEEE 802.16 wimax specifications and will continue to developments as the specifications evolve, but other standards have also been produced based on the 802.16 specification. Some of them are extensive enough to get attention by the Wimax Forum, including HiperMAN and WiBro. Wimax (802.16) effectively holds all of Wimax (802.16) standards.

IEEE 802.16-2004

This standard is the formal one being used for current fixed and nomadic Line Of Sight(LOS) and Non Line Of Sight(NLOS) Wimax (IEEE 802.16) implementations and is based on and backwardly compatible with 802.16 and 802.16a . The WiMAX Forum profiles supporting IEEE 802.16 2004 are in the 3.5 GHz and 5.8 GHz frequency bands. Vendors are currently creating indoor and outdoor customer subscriber stations equipment and laptop PCMCIA cards to support this specification. This standard will be used for cell creation in non-mobile scenarios and LOS distance links.

The theory of duplexing refers to the management of upstream and downstream traffic flows. Frequency division duplexing (FDD) uses two channels. One channel is used for upstream traffic and the other is used for downstream traffic. Time division duplexing (TDD) uses a single channel, and the devices at each end must exchanges between sending and receiving. (Jeff Goldman, July 2, 2004)

IEEE 802.16e

802.16e standard is an extension to the 802.16-2004 specification and supports mobile communications. This mobility is provided through handoffs and roaming support built in to the standard. While intended to provide mobility, this technology is used by service providers to provide fixed access as well. 802.16e specification operates in the 2.3 and 2.5 GHz frequency bands. (Vikki Lipset, September 2, 2003)

ETSI HyperMAN

The European Telecommunications Standards Institute produced the HiperMAN standard for broadband wireless MAN implementations. The HiperMAN standard operates in the frequency ranges between 2 GHz and 11 GHz. It was purposely made in close association with the IEEE Standards; it is based on 802.16 and is compatible with the 802.16a-2003 specification. Like WiMAX, HyperMAN supports both point-to-multipoint and mesh network implementations. (Wimax.com)

WiBro

WiBro Stands for Wireless Broadband, it is a wireless Metropolitan Area Network (MAN) standard initially built by the Telecommunication Technology Association (TTA) of South Korea. Phase 1 of WiBro was approved in November 2004. The standard was developed to fill the space between 3G and Wireless Local Area Network (WLAN) standards; providing more data rate, mobility and coverage required delivering internet access to mobile clients via handheld devices.

The standard uses 100 MHz of licensed Radio Frequency (RF) spectrum, from 2.30 to 2.40 GHz, allocated by the South Korean Ministry of Information and Communication for mobile wireless internet usage, and adjacent to the international unlicensed 2.4 GHz ISM band. The IEEE 802.16-2004 and Draft 3 of the 802.16e standard were the basis for the development of WiBro, and the key PHY parameters are compatible between the two standards. (Steve Rackley, 2007)

The WiBro Medium Access Control (MAC) supports three discreet service levels including guaranteed Quality of Service (QoS) for delay sensitive applications, based on real time polling of station requirements, and an intermediate QoS level for delay tolerant application that require a minimum guaranteed data rate.

Phase 2 of the standard is designed to focus on network capacity enhancement technology, including Multiple Input Multiple Output (MIMO) radio, adaptive antenna systems and space time coding, as well as additional standardization with 802.16e (WiMAX). (Steve Rackley, 2007)

Security of WiMAX Technology

Published by:

Wireless systems always make some people worried when speaking of security. After all, every wireless system broadcasts, by definition, everything you’re doing on the network to the world or at least the part of the world within range. Security is an important consideration in any communication system design but is particularly so in wireless communication systems. The fact that connection can be established in a loosen fashion makes it easier to intrude in an ordinary and undetectable manner than is the case for wired access. Further, the shared wireless medium is often perceived by the general public to be somewhat less secure than its wired counterpart. Therefore, a robust level of security must be built into the design of wireless systems.

From the point of view of an end user, the primary WiMAX security concerns are privacy and data integrity. Users need assurance that no one can eavesdrop on their sessions and that the data sent across the communication link is not tampered. This is usually achieved through the use of WiMAX network encryption. I am going to discuss the encryption in the next chapter in detail.

From the service provider’s point of view, an important WiMAX security consideration is preventing unauthorized use of the network services. This is usually done using strong authentication and access control methods. Authentication and access control can be implemented at various levels of the network such as the physical layer, and the privacy sub layer. The service provider’s need to prevent fraud should be balanced against the inconvenience that it may impose on the user.

WiMAX Technology (802.16) Overview

Published by:

The 802.16 standard was first available on April 8, 2002 after two years in development. The WiMAX Forum was formed in April of 2001 and established in June of 2001. This order might seem odd, but it’s common to shape certification bodies before completing or passing a standard. The Wimax certification will certify that a technology is compliant with Wimax specifications not 802.16. This is because the WiMAX Forum created a certification that is compatible with a portion of the 802.16 standard. Wimax certified hardware should be compatible with other WiMAX certified hardware, but it is important to remember that WiMAX certified hardware not necessarily compatible with 802.16 compliant hardware.

The founding organizations of the WiMAX Forum included Wi-LAN, Ensemble, CossSpan, Harris, and Nokia. The OFDM Forum and Fujitsu joined in 2002. In 2003, Aperto, Alvarion, Airspan, Intel, Proxim, and others joined the group. At this time, the forum has over 200 members with representatives from service providers, system manufacturers, chip vendors, and business organizations. The major focus of this group is to provide interoperability between vendors’ Wimax hardware. (Tom Carpenter, 2006)

In January 2005, at a WiMAX conference called “WiMAX: beyond the Hype,” Gordon Antonello clearly stated that

  • There are no WiMAX networks today.
  • There are no WiMAX form certified products available today.
  • WiMAX Forum certified testing will begin later this year in 2005.
  • Vendors are shipping pre-Wimax products today.

These statements are essential for us to understand that Wimax is brand new and any existing 802.16 compliant hardware might, or might not work with future Wimax Forum Certified hardware. However, some vendors are promising to provide upgrades through firmware or chip replacements to meet the Wimax specifications.

The Wimax Forum began their lab trials in the third quarter of 2005 and field trials in the fourth quarter of 2005. General production deployments are expected in 2006 as true Wimax Forum Certified equipment enters the marketplace.

The final standard being implemented in hardware systems today will support the 802.16-2004 specification of the IEEE. Vendors are building their hardware to this specification and then sending that same hardware to the Wimax Forum for certification.
