Powerline Ethernet describes data transfer over electrical energy lines. What this simply means is as you are able to plug in one powerline Ethernet adapter in to the wall, hook it into your router, and plugin in another adapter near your personal computer, and connect your personal computer to it. You are using these adapters as a means to use your existing electrical lines to transfer internet data. Your online is going right on through existing electrical wire!
This sounds great, and it could be, with some caveats. Let’s dig in. How fast is the powerline adapter. Netgear has some models we are able to use as an example super wireless ethernet bridges the entry-level XE102 model supports up to 14mbs, whilst the mid-range model supports 85MBps, and the most truly effective model claims speeds up to 200 MBps. Gigabit Ethernet over electrical wire is also available.
These ranges are under ideal conditions, and are likely never to be achieved practically. Before getting into the nitty gritty, lets look at wireless speeds. Common wireless technology in 2010 is either 802.11g or 802.11n. wireless-g claims speeds of 54MBps, and Wireless N claims theoretical speeds of 300 Mbps. Actual life issues such as not enough channel bonding, radio interference, overhead of protocols, and so on limit Wireless N to practical limits of 70 MBps.
Measured speeds in non-lab conditions for electrical internet adapters indicate practical speeds of 30-45 Mbps. This depends on encryption, the circuitry of the electrical system, and other electrical interference. There’s not plenty of difference between gigabit Ethernet and 200 MBps when it comes to speeds.
Looking at the data, you would think that wireless is the clear choice. However, really the only way to find out which system works healthier is to test both out. Powerline Ethernet works better than wireless-g for several people, including my house. Your decision for me personally was whether I should upgrade from Wireless-G or simply just get powerline Ethernet. The adapter is cheaper, and it’s possible to connect an instant router to one of these simple adapters as a repeater. I used it, and it worked better for me personally than wireless-G, and was cheaper than upgrading to wireless-N.
