Wired and Wireless Home Networks

As explained in this post, you can build your home network by using either wired or wireless infrastructure. Ethernet, Power Lines and Phone Lines can be used for wired home networks, whereas the dominant technology for wireless home networks is the WiFi 802.11 standard.Below we give you a quick snapshot and comparison of the different home network technologies available.

Home Network Security
A factor that must never be omitted when building a home LAN network, especially when the network is connected to the internet, is how to protect data and preserve your privacy. “Defense in Depth” is the best security approach to take. This layered security concept refers to implementing an outer perimeter layer of security using a firewall (included in the Home Gateway broadband router for example), and then implement inner layers of security (on your internal home network computers) to protect against viruses, spyware etc.
