From Bradley Mitchell, your Guide to Computer Networking
The speed of a wireless network depends on several factors. But one thing is clear: Your network connection will rarely if ever achieve the rated numbers quoted by manufacturers. See - How Fast Is Wi-Fi Wireless Networking?.

Introduction to Computer Network Speed
Bandwidth in computer networking refers to the data rate supported by a network connection or interface. Network bandwidth is not the only factor that contributes to the perceived speed of a network. A lesser known but other key element of network performance - latency - also plays an important role. Learn more about both here.

Free Internet Speed Test Services
An Internet speed test measures the network bandwidth (and sometimes latency) of your connection by using sample data files and test Web servers. You can use these speed test services to measure your download speeds and verify the Internet service provider is supplying you the expected amount of bandwidth. These tools will also help you measure the results of performance tweaking your network setup.

DISCUSS: Comparing DSL and Wi-Fi Speed Ratings
"I really don't understand the relationship between the different theoretical 'speed' claims for DSL (typically 2,3,6,10 or 20 Mbps) and the theoretical claim for WiFi ('g' for example 54Mbps, 'n' 150Mbps). On the face of it WiFi should be substantially faster, but in practise we know that isn't the case, so what am I missing here?" -Cash13

What Is Home Automation
Ask five different people what home automation is and you will probably get five different answers. Simply put, home automation uses technology to make your everyday tasks in the home (or office) simpler, safer, or less expensive. Home automation systems can control lights and dimmers, create or enhance home theater and entertainment systems, strengthen home security, automate locks and doors, increase energy efficiency, and maybe more.
