I've decided to give up waiting for the 802.11n standard to be ratified. When you spend hard earned cash on a piece of kit, you want to have some confidence that it will work in a year or so. Most of the high-end routers on sale today use a proprietary pre-802.11n or draft 802.11n, which may or may not be compatible with devices that meet the standard, when the IEEE pull their finger out.
What is Powerline networking?
Powerline networking has been around for sometime. Essentially it uses your electrical mains wiring as the media to send data over as if it were category 5 cable. You simply plug a box into the wall socket, which converts these signals that multiplex over the mains wiring to Ethernet. Typically you'd have one next to your router, which connects to your routers Ethernet socket, and the other in the room where your computer is located.
Advantages of Powerline over Wireless networking?
One of the main advantages of Powerline networking over Wi-Fi is that there are no dead spots where you can't get a good connection. As long as you are near a mains outlet, you can have a connection; Albeit with an Ethernet cable connected to the wall.
The latest batch of Powerline networking kits are sporting theoretical speeds of up to 200Mbps! Although in practice, overhead in the system, mains wiring and the 100Base-T outputs limit this maximum throughput; However, I have been getting speeds of over 100Mbps along my mains wiring, easily more than 802.11g, and more reliable too.
Installation does not require software drivers, it literally is a case of plugging them into the wall sockets, and connecting up the Ethernet cables and turning them on. This also means out-of-the-box Linux, Vista and OSX support! They'll also work with games machines and media extenders, or any other piece of kit that has an Ethernet port.
I purchased the Devolo HomePlug dLAN 200 AVDesk Starter Kit, which comes with two HomePlug adapters. They include Quality of Service for uninterrupted Internet TV and IP telephony circuitry, and they were given a "best buy" from PC Pro magazine.
There are other manufacturers who produce Powerline networking equipment, like Netgear's HD Powerline adapters, but after reading this review in PC Pro I decided to opt for the devices that conform to the Powerline AV standard.
