We are frequently asked “How can I set up my broadband connection so that I use it in a difference location in my house?”. Sometimes there is a need to use several computers at the same time and sometime it one computer, which is situated a long way from the ‘master’ socket.
There are a number of technologies involved in producing the optimum solution. An appropriate combination of these will depend on the exact layout of your desired system. In this article we will consider four methods, which, in some combination, cover 99% of all requirements.
These technologies are:
Wireless Networking (WiFi)
Networking over the Mains (HomePlug)
We frequently are contacted with questions relating to how to improve wireless reception in the home or just generally in a building.
Wireless networking using the unlicensed and (licensed) 5GHz frequency bands is the new kid on the block. It uses the same basic technology and methods as 802.11g (54Mbps) wireless but operating in the 5.1-5.8GHz frequency bands instead of the 2.4GHz band. Also, unlike 802.11g, it uses OFDM technology over the whole speed range (1-54Mbps); 11g only uses OFDM at speeds above 20Mbps.
