Powerline Ethernet describes data transfer over electric power lines. What this simply means is as possible plug in a single powerline Ethernet adapter into 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 an easy way to use your existing electrical lines to transfer internet data. Your internet is going 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 as much as 14mbs, as the mid-range model supports 85MBps, and the most effective model claims speeds as much as 200 MBps. Gigabit Ethernet over electrical wire can also be available.
These ranges are under ideal conditions, and are most likely not 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. True to life issues such as for instance insufficient 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 is not a lot of difference between gigabit Ethernet and 200 MBps with regards to speeds.
Looking at the data, you’d genuinely believe that wireless is the clear choice. However, really the only way to find out which system works much better is to check both out. Powerline Ethernet works better than wireless-g for all people, including my house. Your decision for me was whether I will upgrade from Wireless-G or simply 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.
