Module 4: Wireless Networking

CMPS 161: Networking and Security


In the previous module we looked at one way signals could be transmitted, namely cables. In this module, we will look at an alternative; electromagnetic waves (specifically micro and radio). There are many standards that define wireless networks, grouped in the 802.11 wireless LAN standard, and we will look at them. In addition, we will look at how both cabled and wireless networks can be used to interconnect LANs. Specifically, we will look at devices that connect networks such as routers and switches.
