Powerline Ethernet describes data transfer over electrical energy lines. What this simply means is that you can plug in one powerline Ethernet adapter 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’re using these adapters as an easy way to make use of your existing electrical lines to transfer internet data. Your online is going through existing electrical wire!
This sounds great, and it can be, with some caveats. Let’s dig in. How quickly could be the powerline adapter. Netgear has some models we can use for example super wireless ethernet bridges the entry-level XE102 model supports up to 14mbs, while the mid-range model supports 85MBps, and the most effective model claims speeds up to 200 MBps. Gigabit Ethernet over electrical wire can be 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 for instance insufficient channel bonding, radio interference, overhead of protocols, and etc 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 is dependent upon encryption, the circuitry of the electrical system, and other electrical interference. There is not a lot of difference between gigabit Ethernet and 200 MBps in terms of speeds.
Looking at the data, you’d believe that wireless could be the clear choice. However, the sole way to ascertain which system works much better is to test both out. Powerline Ethernet works better than wireless-g for all people, including my house. Your choice for me was whether I would 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 adapters as a repeater. I used it, and it worked better for me than wireless-G, and was cheaper than upgrading to wireless-N.
