Hello Skooter Blog readers. Today I talk about buying a Pair EP-Rede Adapters Powerline 200Mbps HomePlug PLC5506 (EP-PLC5506 200Mbps Home Plug Powerline Network Communication Adapters (Pair)) acquired on DealExtreme, whose I've purchased in the last article I reported. HomePlug is the name given to a family of protocols used to enable data transmission (computer network) through the electrical wiring residential.
The Pair EP-Rede Adapters Powerline 200Mbps HomePlug PLC5506 uses standard HomePlug AV, allowing theoretical 200Mbps transmission in a physical layer. The manufacturer is EDUP and the model is the EP-PLC5506, com chipset Atheros AR6405. HomePlug (IEEE 1901) is the ideal solution for situations where you can not pass network cabling: the famous cable pairs locked CAT3/CAT4/CAT5/CAT5e/CAT6/etc. Com o HomePlug, electrical wiring is used to establish network communication, without breaking the walls to pass a new cable. This is a common situation in most homes, which often already have taken all the conduits for electrical wiring, phone, antenna broadcast TV, TV antenna TV out ou, Internet, etc. The installation of the HomePlug is cheap, substantially only the cost of By Adaptadores, and fast. Power outlets are usually available in every room in the house, then the network can be brought to any convenient effortlessly. Devices with Ethernet support usually need electricity to work, then it is very likely that there is already an outlet close by.
The Adaptadores de Rede EP-PLC5506 HomePlug Powerline 200Mbps They are plugged directly into the power outlets, use plug 100% compatible with the new Brazilian standard and also with the old taken, because they use the hexagonal base and two round pins, without ground pin. They work with any voltage between 100 e 240, in 50 ou 60Hz, This means that can be used in Brazil or any region of the world. Each adapter provides an Ethernet port. The most common use on a home network is to connect one of Adapters to an outlet near the router, and then connect it to the router via an Ethernet cable (even). The other Adapter It can then be plugged into any outlet in the house, and an Ethernet cable (even) can be used to connect it to the device you will have access to the network. The connection between the two devices will be done by electrical home network.
Note que os Adaptadores de Rede EP-PLC5506 HomePlug Powerline 200Mbps They operate on the network link layer, therefore do not interfere with anything in the higher layer protocols. This means that your devices connected via HomePlug will acquire the router's IP (if you use DHCP) the same as if they were connected to a common Ethernet cable. The adapter can also be connected to switch (switches), so that multiple devices that are in the same room can share the same communication adapter, each with its IP acquired by DHCP, as in a traditional Ethernet. It is also possible to use more than one pair of Adaptadores de Rede EP-PLC5506 HomePlug Powerline 200Mbps, so that the network is carried out several rooms.
The first version of HomePlug (HomePlug 1.0) was introduced into 2001. In 2005 created the HomePlug AV, capable of providing sufficient bandwidth for TV and high definition applications Voice over IP. The HomePlug AV standard offers maximum speed of 200Mbps in its physical layer, and about 80Mbps in the MAC layer, close to the offered by the standard Fast Ethernet. The Ethernet ports of Adaptadores de Rede EP-PLC5506 HomePlug Powerline 200Mbps use the standard Fast Ethernet, de 100Mbps. Security is provided by AES encryption 128 bits, preventing the signal from your network can be captured by neighbors, even if the signal reaches them.

What I have to review the specifications? We go the. Most specifications are standard HomePlug AV own. The modulation scheme and access control means is something quite complicated, which is natural in the case of a half full of interference. Note that any equipment connected to the power grid can be producing noise with the HomePlug AV standard has to deal. Some of these modulation standards are also used in WiFi, other times from the Internet only via dial-up, etc. Note that while the Ethernet normally works with 4 pairs of twisted cables, HomePlug works with a single pair of parallel wires, who are potential antennas, capturing all kinds of interference. Make a network of functional data in these conditions is already in itself a great prowess. 🙂
The operating frequency, from 2 a 28 MHz is also something to be commented. As the HomePlug works with electricity cables, which by default does not have any type of shield, it is possible that your signal will interfere with other devices that use these frequencies. I do not use, but I've seen some complaints of those who like to listen to shortwave radios, because the HomePlug can impair tuning of these radios.
The operating temperature of 40º C may be worrying for those who live in the region North / Northeast of Brazil, because here in Southeast temperatures are already reaching 35 C, at the time of writing this article, in the dead of night. I believe, however, the device will not refuse to work at room temperature, even if it is a bit higher than 40 ° C specification.
Power connectors, as I have mentioned, has hexagonal base and two round pins. Therefore, are fully compatible with Brazilian jacks on both the old model, as the new standard. They should also fit perfectly in Schuko plugs used in most of Europe. In other countries should work with adapter.
The most intriguing is such a software utility, since it does not accompany the product and found it anywhere. If someone find it, please let me know. It seems to be interesting to have a software to diagnose and configure the encryption keys. However, the product does not require a software to work. Encryption keys can be exchanged and / or synchronized with other adapters using only a small button at the bottom of each adapter.
A common doubt who want to buy such devices is that they work at different stages, in the case of households with two-phase power. The answer is no. I have not tried this test, but the fact is that in two-phase installations, one phase has no communication with others (nor could), at least not without either through own transformer, and the HomePlug signal certainly be lost there. Then there would be no way the signal passes from one phase to another. Neutral is common in both phases, but only one thread not allow communication. The only way to use HomePlug in two different phases is to buy two pairs of devices, using two of them to make a bridge between one phase and another, somewhere where there are different stages physically close.
Another frequent question is whether the HomePlug and replaces the wired and WiFi network. Well, the wired network is always the best option, if you can run Ethernet cabling, do it, for without doubt is the best option for speed, stability and latency. But if you do not want to break walls and do not need such high speeds as Gigabit Ethernet, then HomePlug is the best solution. If the idea is just to share the Internet with a computer in the room, a HTPC in the living room, a video game (PS3, XBox, etc.), or SmartTV, etc. he will probably do their job well.
What about WiFi? The IEEE standard 802.11 (WiFi) is the ideal solution for mobility. If you have a mobile device like a laptop or cell phone, HomePlug is not an option as well as Ethernet is not, then WiFi is your only option. But many people are using WiFi (as I also had been using) to connect devices which are actually fixed, como a Smart TV, the game, o Blu-ray player, among others. In this case, HomePlug is usually a better choice, it reaches higher speeds than WiFi when used at the same distance, besides being more stable, because the WiFi is subject to more interference, is other WiFi networks in the vicinity, is from other devices using the same frequency, as Bluetooth, etc. Even if the power source is very subject to interference, it is even less subject to interference than the wireless networks. Anyway, both protocols are quite robust for error correction, so that higher-level protocols (network, transport, application) do not usually notice these weaknesses.
And how are the speeds in practice? Firstly, worth mentioning that the Adaptadores de Rede EP-PLC5506 HomePlug Powerline 200Mbps shall not be binding on UPS or stabilizers, as this seriously degrades performance. These rules which are often just extensions without any filter or protection do not appear to significantly decrease bandwidth, but it is good to avoid them and connect the devices directly into the outlet when possible.
My goal with Adaptadores de Rede EP-PLC5506 HomePlug Powerline 200Mbps It was to bring the router's network to devices in the room, including a Smart TV, a Playstation 3, um WD TV Live, and more recently a Blu-ray player. All were connected via WiFi, o Playstation 3 with the native adapter, Smart TV with a bridge Netgear and the WD TV Live with a USB adapter Netgear. The performance of all was somewhat tolerable, well short of the IEEE 802.11g standard offered by even more offered by the IEEE 802.11n standard (supported by the two Netgear). The poor performance reason probably are the various walls between the two rooms, beyond the neighborhood WiFi networks. The speed with WiFi was just enough to take the same 2Mbps Speedy, sometimes not even that.
But connect the HomePlug here also was not an easy task, because the room is where the router is also the computer and other devices that use the same wire. And the electrical wiring to get to the room must pass at least another couple of breakers on the way. The speed I could use the same socket on the PC and router to the mains TV was about 9Mbps the router sense -> room, which was sufficient for 2Mbps Speedy and gave some comfort to possible fluctuations. But when I changed the Speedy 2Mbps to 10Mbps Net lack of speed began to bother. Some unexpected interference sometimes let the speed at about 1Mbps, what hinders not play online on the Playstation 3, for example, but hinders watch a movie on Netflix, passing from HD to SD and sometimes even gives a tangled if the speed is too low. Eventually the connection came to be lost.
To solve the problem did test several other outlets. The fastest speed I got was 36 Mbps in one direction and 21 Mbps in the opposite direction (the velocities in both directions always tend to be different), taken using in adjacent rooms. In the end I opted for an outlet in a corridor adjacent to the router of the room and take TV, obtaining an approximately 20Mbps speed on the router sense -> room and ecerca of 12 No sense Mbps reverse. For it had to take an Ethernet cable from a 6 meters from the router to the outlet, but it is still better to take the cable through the house.
Not notice much variance in velocity over short periods of time, but there seems to be some equipment in the house with potential to degrade the performance considerably on occasion, but have not figured out what yet. Perhaps the villain is the very quality of the energy supplied by the concessionaire, since the times I hear the relays UPS by switching at frequencies somewhat out of the ordinary. The fact is that 20Mbps offers some slack, so no need to worry about the speed when viewing a movie on Netflix, for example. But, if he wanted to use the PC as a media server to the TV or Playstation, watch movies in high definition perhaps could present any problems. Note that in any test the LED that indicates the speed of the grid left the red, indicating slower speeds as mais. Yellow and green indicate average speeds indicate higher speeds. I think my wiring is not good enough to get a yellow or green. I did not get to test the two adapters on the same ruler or even in the same room, then it is possible that in all my tests were breakers on the way, did not get to check it out.
Note that network to distribute the signal to all room equipment used a Switch Fast Ethernet 10/100Mbps com 8 ports Auto MDI / MDIX (8-Port 10/100M Fast Ethernet Desktop Switch (Auto MDI/MDIX)), of which I will speak in the next article. Speed measurements were made using the LAN Speed Test software, writing and reading data on external hard drive WD TV Live, from a PC connected to the router with unshielded twisted pair Cat5e, using Gigabit Ethernet.
I can say that I am quite satisfied with the Pair EP-Rede Adapters Powerline 200Mbps HomePlug PLC5506, that meet my expectations and offers a faster rate than I used to get with a WiFi network (IEEE 802.11n) theoretical 300Mbps. Furthermore, stability is also higher, you can test the latency for hours without noticing any significant variance and no packet loss.
