  • Address to the readers by the WiMAX Forum president Ron Resnick

    P Dear readers! Let me congratulate you on the new book WiMAX encyclopedia. Way to 1;, appearance. Why is it so important nowadays?

    The world population is 6.75 billion people, 4.05 of which use various types of telephone communication cellular networks. 3.5 billion use the Internet and only half of a billion use a broadband wireless access to diverse networks. Modern technologies and progress in general causes the rapid growth of broadband wireless access. However, the growth is restricted by various factors including necessity of large financial expenditures on the global networks infrastructure. It took mankind more than a century to develop a global telephone network: this very network was used for the Internet access at the first stage of its development. Howev-

    er. ii rapidly became apparent that novel networks are absolutely necessary for the broadband access. Not to spend another hundred of years on global network development it is natural to use the mobile radio communication technology.

    Thus broadband wireless communication networks became one of the main directions of telecommunication industry development. For the countries with vast territories and low density of population, wireless networks have special significance since they make it possible to develop a large scale telecommunication infrastructure effectively and efficiently.

    Even if WiMAX is not the only broadband wireless communication technology. it took in all the best from the borderline technologies like 3G. I E E E 802.11. DVB. DAB etc. That is why from our point of view it is WiMAX that is the best solution for broadband wireless internet access unpeople in both developing and developed countries. WiMAX technology enables both mobile and fixed line providers, including absolutely new ones start ing from scratch, to progress rapidly. More Thau 475 WiMAX networks in 140 countries are developed already. There are numerous WiMAX providers in Russia and CIS. .Nearly half of a billion people live in the regions where WiMAX providers operate or WiMAX licenses have effect. A year later the amount of people will reach the number of 800 million. International nonprofit association WiMAX Forum includes more than 400 companies hardware components developers. OEM companies, all kinds of telecoms operators

    and WiMAX ecosystem. That is why the book in your hands is

    so highly important and timely. WiMAX is a bunch of thriving technologies connected to almost all of the telecommunication areas. Most of the technologies from indispensable basics of communication theory to description of specific tech-

    nologies. equipment, and network architecture are fully represented in this monograph. Thai is why this hook is rightly called .WiMAX encyclopedia. I believe it is vital that authors didn't confine themselves to the only technology. There are descriptions nf related and rival standards in the hook as well, which make it possible for a thoughtful reader to arrive at a conclusion himself ahout the future of the global mobile telecommunications.

    All stated above makes this hook a unique and actual publication which will surely make a contrihution to the development of the 4G networks. This hook is equally useful for everyone who deals with development, using or adjusting of the broadband wireless systems, hut first of all for those who deals with WiMAX. Go for it!
