Facts About WiMAX And Why Is It “The Future of Wireless Broadband”

WiMAX in detailIn this article we will talk about wimax in detail. WiMAX is a technology standard that enables Wireless transmission of data at broadband data rate.

WiMAX(Worldwide Interoperability for Microwave Access) is one of those telecommunication technologies, which have been quoted as the ‘Future of Data Communication’ by many industry experts and there are enough reasons for WiMAX to be called so.

WiMAX is basically a technology that enables Wireless transmission of data packets at broadband data rate. It empowers computer or mobile terminals with enhanced mobility and ability to access ‘High Speed Internet’ without the need of connecting the terminal to any cable network or Wi-Fi hotspot.

WiMAX is often confused with Wi-Fi, another wireless telecommunication standard, but both of these standards are much different in terms of infrastructure pre-requisites and network capabilities. Wi-Fi is basically a limited wireless extension of the conventional wired telecommunications network, using which we can access wireless internet within a small range of 10-100m from the Wi-Fi access point, whereas WiMAX provides long range wireless internet access at broadband speed, with the help of a dedicated network infrastructure, built exclusively for wireless data communication at much higher speed.

Below are facts related to WiMAX, which elaborate the concept, fundamentals and technical details of WiMAX:

Definition: Technically, WiMAX is a Broadband Wireless Access technology based on the IEEE 802.16 standard, which enables high speed packet data access on a mobile terminal (laptop, smartphone..) without any access point dependency

Types: There have been majorly two developments with regard to WirelessMAN broadband: Fixed WiMAX and Mobile WiMAX. The earlier of the two WirelessMAN standards,Fixed WiMAX(or IEEE 802.16d) employs High gain-low portability uni-directional antenna at user’s end and provides a limited wireless broadband access. It supports following sub-channels: Single High Gain  carrierOFDM 256 FFT(Fast Fourier Transform) and OFDMA 1K-FFT

Mobile WiMAX(or IEEE 802.16e) takes the Wireless broadband access to much larger coverage area as it employs Low gain-High portability Omni-directional antennas at user’s end(in the form of Flash drive sized modem). Mobile WiMAX supports not only Single carrierOFDM 256 FFT and OFDMA 1K-FFT but also OFDMA 2K-FFT, 512-FFT and 128-FFT sub-channels

Infrastructure: Implementation of WiMAX requires a similar scale of basic telecommunication infrastructure, as built in case of a voice communication network(GSM, CDMA). Base Stations, sectorized antennas, control center and other critical constituents are generally a part of such infrastructure

Coverage: WiMAX network has often been claimed in media to be capable of providing broadband speeds to a coverage of over 30 miles(with a single base station) but that’s possible only in ideal conditions(Line-Of-Sight(LOS) area, No real-time traffic, negligible attenuation..). Practically, a single base station can provide a satisfactory broadband access within a range of 4-5 miles(Non-LOS and real-time traffic conditions). With LOS conditions, the coverage can go upto 10 miles. Rest of the coverage and Quality-of-Service(QOS) details are solely dependent upon the terrain and population conditions

Terminology: IEEE 802.16 standard is generally referred as “WirelessMAN” but the term “WiMAX” was actually given to IEEE 802.16 standard by WiMAX Forum,founded in mid 2001 to take care of conformity, interoperability and promote the IEEE 802.16 standard(or Wireless broadband) at a global scale

Limitation: The major limitation of WiMAX is the effect of QOS in high traffic, non-LOS areas. It’s quite impractical for WiMAX networks to support over 40 Mbps of internet speed at a distance of 15-20 miles. This limitation is quite unavoidable and found in other wireless networking standards as well.

Future: The future of WiMAX looks brighter as there are already over 475 WiMAX networks deployed in 140 countries worldwide and the network extension is happening at a very fast pace. See the list of deployed WiMAX networks here. Also, as it offers a cheaper and more bandwidth-efficient way of providing Wireless broadband(compared to 3G), it is likely to become the De-Facto standard in Wireless Broadband services.

      I would be surprised if Sprint has a sonrtg future due to some basic business practices of theirs. Like many of the other huge wireless corporations, Sprint insists on locking people into long contracts. If Sprint was confident in their offerings they wouldn’t try to lock people into staying with them.My company is in Austin, TX and Sprint insisted that they have excellent coverage and could provide us the GPS tracking that we needed. We got over a dozen phones and two high-speed data cards. Since we started service, we have had terrible coverage, text messages take up to 12 hours to reach the recipients, and the high-speed data cards have never worked. The GPS tracking was a joke and NOT what they showed to us.We have talked to the sales people, tech support, corporate, and have never gotten a response. Recently they have raised the text messaging rates even though we were under contract.What is the purpose of a contract if the company can change the rates but won’t let the consumer out of the contract?People are starting to wise up about Sprints deceptive practices and how cellphone contracts do not benefit the consumer, only the vendor. All they do is lock you into service that doesn’t work.I worry about the 4G rollout. What good is a high-tech network if the management of that network is substandard? Let’s hope Google wins their auction for the new opening spectrum and leases it out to anyone who wants a slice. Adam BrownLonghorn Services longhorn-services.comSeptember 7, 2007 | 12:34 pm

    Wimax offer more bandwidth and more services than traditional microwave communications. “~*

      I’m a Wimax subscriber for more than a year now. The first time I etnouncered Internet issue was last July 22. The issue is still unresoved until now August 15. Their CSRs don’t know squat about internet service. One even stole my MAC and Device ID for his own use. Their field techs don’t even bother to check if the issue has been resolved. They kept closing the ticket as no trouble found so that Globe will recreate a job order and they do get paid per job. These field techs are subcontractors. It’s also not the signal. they’ve checked and rechecked already. It’s just slow because that’s how Globe configured the connections at the base to squeeze all subscribers in a few cards. To new subscribers, DO NOT GET ANY GLOBE DSL OR WIMAX SERVICE. It’s unsecure, slow, and bad customer service. Trust me, I’m still in Globe hell now.

    I’ve already been studying your records all through my morning hours crack, and that i should acknowledge the entire article continues to be really educational and really well written. I assumed I would allow you to realize that for reasons uknown why this kind of weblog does no more view well within Net Explorer Eight. I would like Microsoft may stop altering their software. My partner and i’ve a query for you. Could you ideas replacing website move back links? That could be in fact well put together!

      thanks brothers for the nice adeicvs that you had given above and yesi agree to you all that in philippines stil need lots of improvment for internet providers that all they saying is all lies.i recently buy smartbro power plugit 5mbps speed and when we buy we ask that in my locationg it can works thy say yes with full signal so we buy that and we chek ahh its really shit on me its give us only a GPRS connection and abt 3G ahh evn no single bar and we ask to smartbro thy saying thy will report abt this bt until now its not wrking.browsing takes to load a webpage morethan 3mins and voice and video chatting its really sucks.every min thy dc and makes me so we try to buy wimax from globe and what i read here now i decide not to buy cz of wasting lot of money and result is a BIG ZERO ..
