WiMax For A Wire Free World
ADVERTISEMENTS
Worldwide Interoperability for Microwave Access or WiMax is a leap in wireless technology giving wide are wireless broadband technology in a short span of time. As it can cover relatively long distances, it has the potential to serve everything from low density residential applications to enterprise customers. Before we get to know Wi-Max technology deeper lets cover up today the basics so we can be ready for more details.
Wi-Max Basics
WI-Max is defined as standards based technology enabling the delivery of last mile wireless broadband access as an alternative to generally used cable and DSL. It offers advantages over Wi-Fi, in terms of greater range and bandwidth efficiency. It can give speed upto 75 MBps at every station (Station are points from where wireless waves are send to other places so signal doesn’t get weak). With this speed it can cover up the whole city and make them free of wires.
How it is better than DSL and Cable Modems
DSL and Cabel Modems suffer from two biggest disadvantages low speed (you can say they have good speed but when you have to download movies and games its still very slow) and lot of wires. They need to boost up the speed every few kilometers and hence fills up cities with wires everywhere.
With WI-MAX these disadvantages are removed
- Being wireless there is no cluttering around
- Each station can provide a boost of 75MBps download speed which can cover the entire city easy. Imagine how it will be if DSL are going to cover everything with wires.
- This also removes the problem of maintaining the wires and their connection which has definite shortcomings when it gets damaged somewhere
Even Intel has started implementing Wi-Max technology in it’s motherboard. So soon we will be seeing Wi-Max ready computers. Take a look at the image below and you will get the idea of how Wi-Max works.

Nice post Ashish wi-max technology is the real future of broadband connection and the pic you have posted is also very nice which clear every doubt about working process of wi-max technology information .

: Glad the picture was clear, but I am little biased w-max being the future. Mobiles are the future of coming generation and wi-max is not so great on portable devices. It might work for the current scenario but we have another set of protcol which is coming soon specially for portable devices. Just wait to know about it.
: Great you liked it Chris,

WiMax wouldnt definitely be the future. When it comes to mobile world there will be/are already a lot of technologies like GPRS/EDGE/HSPDA.
Irrespective of the access (Wired/Wireless) the next big thing would be IMS (i.e. when operators start adopting it
)

: GPRS and others are things of past, they are 2.5 or 2G technology. We are now looking at 3g( like Nokia N72 and E series) and 4G enabled devices now, 2G phones will be outdated soon.
can you give the longform of IMS?

Ashish, not sure if GPRS a “past” but EDGE and HSPDA are supersets of GPRS itself.
We in India haven’t still looked at 3G as far as I know. I had a change to experience HSPDA network in US (Cingular).
In India we are still stuck with Airtel/Hutch/Reliance providing sucky EDGE speeds (download at 3KB-6KB/second)
My comment on IMS (IP Multimedia System) was in support of your comment saying “Mobiles are the future of coming generation”
IMS is based on packet based IP networks and access to this packet base can be anything WiMax,WiFi,DSL,GPRS/EDGE etc

: There is one reason India is still not ready. If you chnage from one tech to another, its really necessary to change infrastructure. Second 3g phones are still costly in India. You might get some supersets just to increase speed but how long they will live ? They might have a life in India from a while coz of the drawback of infrastructure but not in advanced tech.
IMS I need to look around. I know one tech coming for mobile tech which is comparative to wi-max…its called as Mobile-Fi which is 802.20 standard while wi-max is 802.16
So we have to wait and see how it goes. But one thing is sure if you want a phone don’t buy a 2g phone get nokia n series or E series. They will be good for future.

I don’t wether Wimax will be the lead connection-technology in future, I think it will be one between many.

: I agree to you on that. There are lot of standards coming up as an alternative to wi-max. Check out the ping list on this post

i wnat to know how to setup a wimax network and the equipments and softwares used to be able to connect 3 offices together to share resources amongst them and to one VSAT to be able to share one internet connection to minimise costs. Please could you give me an idea on how much it would cost and where i could purchase the equipment from.

Please send me
1. how threshold cryptography can be used in WiMAX?
2. Secured authentication in Wimax initialisation
3. How digital X.509 certificate is used in WiMAX initialisation
4. Is it possible to divide digital certificate into different BSs. If so how?
5. Some relevant ppt for the above points.

hello friends iam dng project on wimax
topic is “connection admission control framework with QoS support ieee 802.16(wimax) for broadband wireless network”.
i want framing algoritham using TURBO C based plz any one have tel me and more details of wimax.
