Chapter 10. Designing Enterprise Wireless Networks

After completing this chapter, you will be able to

Identify the wireless LAN solution
Design wireless LANs for enhanced enterprise communications

Simply put, a wireless local-area network (WLAN) does not require wires. It uses radio frequencies instead of a traditional media, such as copper or fiber. It provides real-time access to the network. With a WLAN, the covered area is essentially comparable to that of a wired LAN. In large applications, by deploying a series of access points throughout a building or campus, enterprises can achieve more coverage than a wired network, with the benefits of high-speed data rates and the freedom of mobility from being able to access broadband data anywhere within ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
