Next Generation Wireless LANs
If you’ve been searching for a way to get up to speed on IEEE 802.11n and 802.11ac
WLAN standards without having to wade throu gh the entire 802.11 specification, then
look no further.
This comprehensive overview describes the underlying principles, implementation
details, and key enhancing features of 802.11n and 802.11ac. For many of these features,
the authors outline the motivation and history behind their adoption into the standard. A
detailed discussion of the key throughput, robustness, and reliability enhancing features
(such as MIMO, multi-user MIMO, 40\80\160 MHz channels, transmit beamforming, and
packet aggregation) is given, in addition to clear summaries of the issues surrounding
legacy interoperability and coexistence.
Now updated and significantly revised, this 2nd edition contains new material on
802.11ac throughout, including revised chapters on MAC and interoperability, as well as
new chapters on 802.11ac PHY, and multi-user MIMO, making it an ideal reference for
designers of WLAN equipment, network managers, and researchers in the field of wireless
communication.
Eldad Perahia is a Principal Engineer in the Standards and Technology Group at Intel
Corporation. He is Chair of the IEEE 802.11 Very High Throughput in 60 GHz Task Group
(TGad), the IEEE 802.11 Very High Throughput in <6 GHz Task Group (TGac)
Coexistence Ad Hoc Co-Chair, the IEEE 802.11 liaison from the IEEE 802.19 Wireless
Coexistence Working Group, and the former Chair of the IEEE 802.11 Very High
Throughout Study Group. He was awarded his Ph.D. in Electrical Engineering from the
University of California, Los Angeles and holds 21 patents in various areas of wireless
communications.
Robert Stacey is a Wireless Systems Architect at Apple, Inc. He is the IEEE 802.1 1 Very
High Throughput in <6 GHz Task Group (TGac) Technical Editor and MU-MIMO Ad Hoc
Co-Chair. He was a member of the IEEE 802.11 High Throughput T a sk Group (TGn) and a
key contributor to the various proposals, culminating in the final joint proposal submission
that became the basis for the 802.11n draft standard. He holds numerous patents in the field of
wireless communications.
“The authors are renowned experts in the field. The book is a must read for engineers
seeking knowledge of recent advances in WLAN technologies.”
Dr Osama Aboul-M agd; IEEE 802.11ac Task Group Chair.
“First edition of the book “Next Generation Wireless LANs” by Eldad and Robert is
excellent and very popular. The second edition adds newly developed IEEE 802.11ac
standard with the same excellence in addressing technical features and easy to read
writing style.”
Vinko Erceg, Broadcom Corporation
“The 802.11 standard has been evolving for over 20 years and now contains nearly
3000 pages of information. The authors have had direct involvement in writing many of
those pages. This book represents a significant accomplishment in conveying and
explaining the engineering behind the features for two of the most important radio
options provided by the standard. Radio engineers approaching the standard for the
first time as well as those already engaged in product development will find this text
remarkably rewarding.”
Bruce Kraemer, Marvell Semiconductor and Chair, IEEE 802.11 Working Group
