Sample Products in the Field of Data Transfer Over Powerline Ethernet
Homeplug and Universal Powerline Association (UPA) are the 2 principal standards for powerline ethernet. With both standards, you would just plug in your first adapter into the outlet, and your second adapter into the second outlet, and connect your network cable to each of these adapters, and the network will be complete. Do keep in mind that the standards aren’t cross compatible; you either have to use Homeplug, or UPA. Technical support is available if things do not proceed as smoothly as planned. Sometimes, either electrical interference, or having the adapters on different circuits causes a problem. Powerline ethernet is preferred in situations where wireless cannot reach, or just because of cost reasons. You probably would need a Wireless-N connection to match the speed of a good powerline ethernet connection. What follows are some adapters that are popular in the marketplace in 2010.
The D-Link DHP-303 PowerLine HD is a two hundred Mbps powerline package, and comes with two DHP-302 adapters. This setup is compatible the Universal Powerline Association (UPA) standard, therefore only adapters supporting UPA can be added to the setup. Other common adapters use Homeline AV, but because it is recommended to stay with the same manufacturer, this limitation is probably not too concerning. Performance-wise, the adapter kit gives speeds of somewhere between seventy-five to ninety Mbps which is better than Homeplug AV adapters.
A great feature is the powersave technology. Whenever no data is being sent, the powerline adapters can power down saving energy. The port, there’s just one, supports 10/100 ethernet. Both IEEE 802.3 and IEEE 802.3u are supported. The encryption available is Triple-DES. This is a robust mechanism, however it is a less efficient algorithm than AES. Triple-DES must do encryption in 3 passes, while AES needs only a single pass to encrypt data. The kit does include a 1 year limited warranty.
The Western Digital Livewire Powerline AV Network Kit is model #WDBABY0000NBK
and is a 200Mbps powerline AV kit. It consists of 2 4-port HomePlug AV adapters, and a couple of electrical power cables. As the name says, this is HomePlug AV compatible, and comes as a compact box of around 4.7 x 3.4 x 1.3 inches. The great thing about these kinds of box models is the fact that they don’t use up an entire outlet. Instead, you plug them in with a small plug, and so they sit as a separate box. WD has a nice claim that setting the kit up is as simple as plugging in a table lamp. Yes, it is a lamp with ethernet cables, as well as 128 bit AES encryption, but I like the imagery and it is a good thing to aspire to with every technical product.
I believe the best selling point is that each adapter includes 4 ethernet jacks. This really offers versatility in the network architecture, and leaves room to grow. At the moment this data rate is adequate for most home applications.
