Chapter 16Security in Wireless Metropolitan Area Networks (802.16)

Metropolitan area networks (MANs) link local area networks (LANs) to larger networks, such as the Internet, through a high-speed connection. This chapter presents the security mechanisms in the newly approved IEEE 802.16 standard for wireless MANs, which provides the interface to high-speed wireless links using licensed and unlicensed radio bands to fixed locations, such as rooftop antennas. We describe the protocol, the security mechanisms, and potential limitations.

16.1 Broadband Wireless Access

MANs link commercial and residential buildings to the Internet through a high-speed connection. Typically, an Internet service provider (ISP) supplies the MAN. The links can be dedicated ...

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.
