1. Rare combination of in-depth technical details at the same time serving as a ready reckoner / cheat sheet for specific lookup of information. e.g. specific examples from my case - quick read-up on 802.11 k/v/r details instead of having to go through several pages of the spec., quick look up on DFS radar detection and channelization in 6 GHz.
2. Newbies to WiFi not left behind : Even though this book is dedicated to WiFi 6, it does give a good overview of the previous generations of WiFi from 1 to 5, with all important details concisely provided for the reader to pickup the fundamentals.
3. Authors have combined technical details from IEEE and WFA specifications with their practical hands-on experience with products and handled the subject in a pragmatic manner. E.g. The section on “When to do SU, MU-MIMO and MU-OFDMA” discusses various factors that would impact the performance in these different modes and illustrates them with examples that does quantitative analysis.
4. A peculiar trait that I saw in this book is a chapter dedicated to a WiFi product implementation starting from Hardware, covering lower layers of embedded software all the way to the host software and upper application layers. It talks about the WiFi Chipset SoC aspects like CPU, memory, bus interface to the host platform and seamlessly switches over to Radio characteristics like impairments and calibrations to mitigate them, Tx EVM, Rx Sensitivity, & then gliding over to specific aspects of firmware and host software implementation considerations. This would give a unique end-to-end perspective to the reader.
5. The book is for the embedded hands-on developer as well as for a system level WiFi engineer looking at a deployment level across a home or an enterprise. You could use it when developing specific pieces of WiFi firmware or host software as well as one could use it while looking at an enterprise or home deployment and troubleshoot intricate problems like performance, coverage and connectivity.
6. Terse and to the point focusing on the specifics and the intent of the authors is loud and clear. This makes the book less bulky in size while providing all the relevant and precise information.
I strongly recommend this book for all newbies to WiFi as well as to experts to use as a ready reckoner. I have worked on WiFi products since WiFi 2 onwards up to WiFi 7 and I find this book very useful and relevant for my day job today. My sincere thanks to the authors for bringing this book out for the benefit of the wider WiFi community.
