We are now approaching the end of the second decade of the 21st
century. Digital content is constantly growing in size, and it's not
unusual to hear of games that have a size of 30GB or more. Data
Alliance estimates that we're transferring more than 1,100 billion of
GB on the Internet each year!
How does this happen? We stream, download and run content on a
wide variety of Wi-Fi devices: smartphones, tablets, laptops,
desktop computers, and so on. But that's not all! Lots of other
devices in our homes are connected to the Internet. We've got
smart fridges, smart coffee makers, smart lightbulbs, smart garage
door openers, and more.
Okay, so this book is quite short. It's only got 35 pages!
But, truth be told, it includes everything you need to know about
the new 802.11ac standard. And, unlike most tech books, it's 100%
free. Yeah, this means no affiliate commission for me. It's a clear
proof that I pursue my readers' best interests.
The book was sponsored by Intel; it's got a blue "Intel Special Edition" stripe at the top of the cover. And
when you also take into account the fact that it's one in the successful "For Dummies" series, you bet it's a
It's clear that yesterday's Wi-Fi technologies can't keep up with the increased data transfer speed. But
don't despair! The newest Wi-Fi standard - 802.11ac - has arrived, and it is 600% faster than the previous
iteration. Yeah, now you can safely stream your YouTube TV movies in full HD, even if your kids are
playing the most demanding online multiplayer game on their consoles.
Hold on, it's just the beginning! The new Wi-Fi version can handle 300% more clients. Let's be frank and
admit that this is a necessity in most American homes, because we've got a total of 7...9 devices that can
connect to the Internet in every household.
Signal range has increased as well, due to better, more reliable data compression algorithms. And since
your data can be transferred faster now, smartphone batteries will last longer!
You can tell that I'm excited about 802.11ac, right? So, what's so great about this book?
The author starts by discussing a major Wi-Fi roadblock: wireless signal congestion. According to him, 60%
of the Wi-Fi traffic consists of videos, which need a high speed, reliable wireless Internet connection.
There are a few interesting (and funny) stats in this chapter, so don't skip it - you'll see what I mean ;)
The second chapter is my favorite. It explains the technologies behind Wi-Fi for beginners, and David is
really good at it. If you've ever wanted to find out about wireless access points, Wi-Fi standards, MIMO,
hotspots, Wi-Fi adapters, theoretical data transfer speeds, REAL data transfer speeds, this is the chapter
to read. Oh, and it's got lots of useful illustrations as well!
The third chapter will help you pick the best Wi-Fi equipment that fits your needs. It's a fantastic addition
for people who want to purchase a new tablet or laptop, for example. David also lists several access
points vendors; I have studied his list and it's one that I'm happy to recommend as well.
If the mere thought of opening the computer case sends shivers down your spine, fear not, because the
author shows you how to identify the Wi-Fi devices that are installed inside your PC or laptop. He
produces top Wi-Fi adapters indeed.
The last chapter discusses the top 10 Wi-Fi equipment shopping tips. They range from being connectivity
conscious to buying your wireless equipment for tomorrow, to much more.
I really like this book. Too bad it's so short! You can probably read it all within 20 minutes or so. But hey,
that's not necessarily a bad thing, because people like to consume information in small bits these days.
If Wi-Fi terms and technologies scare you, this book is just what the wireless doctor ordered for you. Go
and download it now and (as the author says) "keep this guide handy".
