Powerline Ethernet describes data transfer over electrical energy lines. What this simply means is that you could 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 an easy way to utilize your existing electrical lines to transfer internet data. Your internet is going through existing electrical wire!
This sounds great, and it may be, with some caveats. Let’s dig in. How quickly could be the powerline adapter. Netgear has some models we could use as an example super wireless ethernet bridges the entry-level XE102 model supports around 14mbs, as the mid-range model supports 85MBps, and the very best model claims speeds around 200 MBps. Gigabit Ethernet over electrical wire is also available.
These ranges are under ideal conditions, and tend not to be performed 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. Real life issues such as for example not enough 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 lots of difference between gigabit Ethernet and 200 MBps with regards to speeds.
Considering the info, you would believe that wireless could be the clear choice. However, the only real way to determine which system works healthier is to check both out. Powerline Ethernet increases results than wireless-g for many people, including my house. The decision for me personally was whether I would upgrade from Wireless-G or simply get powerline Ethernet. The adapter is cheaper, and one can attach 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.
