From the intro:"INTRODUCTORY I suppose every thoughtful person from time to time takes up with himself the question of prayer. It was not a good man who said: "What profit should we have, if we pray unto him?" (Job 21:15). But it was a very natural question and a thousand others than he has framed it, sometimes in thought, and at other times in words. How can God answer prayer if He be all-knowing and all-powerful? Why should a Being who could create a universe like this care to listen to beings like us, so ignorant, so short-lived, so sinful, so helpless? Nevertheless, the impulse to prayer is irresistible. Someone has said: "Man is incurably religious; man is incurably prayerful." I was talking with a lad not long since, and asked him if he prayed. He replied: "Yes, sometimes." I said: "When do you pray?" He said: "When I get scared." He was not peculiar in this respect; in a cyclone or in a storm at sea, in a time of deathly illness or of financial disaster, men pray, naturally they do this. They do not have to be taught, they simply pray. Infidels, even those who call themselves atheists, when- these times of stress and storm come upon them, reach out into the dark for God."
Broadband Fixed Wireless Access provides a systematic overview of the emerging WiMAX technology, and much of the material is based on the practical experiences of the authors in building new systems. This material will be of significant interest to network architects and developers of broadband fixed wireless access products. With the advent of the IEEE 802.16 standard (has the standard or any part of it been adopted or is likely to be adopted soon?) and next generation equipment, this technology has been growing in interest. The authors discuss applications at microwave frequencies between 2 and 11 GHz that could be attractive options for operators without an existing access infrastructure for reaching end users. This introductory volume demystifies the technology and provides technical exposure to the various system trade-offs. Additionally, the book features the following highlights:
- Detailed modeling of broadband fixed wireless access propagation channel, including new measurements for its time variation
- An extensive overview of the IEEE 802.16 standard
- A tutorial on implementation challenges for WiMAX terminals
- Discussion of the suitability of various multi-antenna techniques
- Elaboration of various techniques, i.e. autodirecting antennas, bridging with WLAN, and multi-hop networking, that can be used to reduce the cost of ownership of a WiMAX network for an operator
The authors cover a wide range of topics, from network deployment to implementation of terminals. Wireless professionals will gain a head start from the information on WiMAX technology. This is a must read book when starting with broadband fixed wireless access.
