Frequently Asked Questions

What is powerline networking?

The core idea of powerline networking is to extend your home network over the electrical powerlines using Extollo powerline adapters connected to the electrical sockets in your home. The term powerline refers to the electrical connections in your home. Similar to cable and telephone lines, powerlines are also capable of transmitting digital signals such as Voice, Video and Data.

What is the difference between HomePlug and powerline networking?

HomePlug is a standards organization. In 2000, a group of networking and electronic firms created the HomePlug Alliance with a goal to standardize pow- erline technologies for home networks. This group has produced a series of technical standards named as versions of "HomePlug".

What does PLC stand for?

PLC stands for Power Line Communications.

How is the information transmitted over the electrical powerline network?

The PLC signal is superimposed through a coupler at a high frequency (2 to 86 MHz) with low energy levels onto the existing 50Hz or 60Hz AC electrical power lines. The power lines then become the transmission medium for the PLC signals. Other adapters on the same powerlines decouple and process the PLC signal.

How fast is HomePlug networking?

HomePlug 1.0 supports a physical layer data rate of 14Mbps. A follow-up “turbo” specification increased the physical layer data rate to 85Mbps. HomePlug AV standard has a physical layer data rate of 200Mbps. Some vendors have added the IEEE 1901 extensions to their HomePlug AV hardware that boost its physical layer data rate to 500 Mbps. HomePlug’s AV2 standard defines two profiles, a 500Mbps and a 1.5Gbps physical layer specification.

What are the HomePlug standards?

HomePlug 1.0 was first introduced back in 2001 and had a physical layer data rate of 14Mbps. It's now becoming obsolete. HomePlug AV, introduced in 2005, has a physical layer speed of 200Mbps, which is fast enough to carry multimedia content, hence the AV designation for Audio and Video. This stan-dard also supports 128-bit AES encryption for security. HomePlug AV is backward-compatible with HomePlug 1.0 and is typically marketed as HomePlug AV 200. IEEE 1901, in 2010 the IEEE ratified the 1901 standard which was based off of the HomePlug AV standard. Whereas previously HomePlug was anindependent standard, this brought it under the same IEEE umbrella as the other networking standards and protocols. The 1901 specification guarantees interoperability between adapters from different semiconductor vendors, and on top of that, the physical layer speed was increased to 500Mbps. Home-Plug AV2 standard is a further evolution of the previous AV iteration, providing physical layer improvements to 1.5Gbp. HomePlug AV2 is backward-compatible with HomePlug AV.

Why is HomePlug AV2 better?

HomePlug AV2 has several technical advances over the previous standard called HomePlug AV.

  • AV2 MIMO improves the physical layer rate to 1.5Gbp versus 200Mbps with AV.
  • AV2 extends the performance coverage throughout the home with repeating capabilities.
  • AV2 increases the frequency band up to 86 MHz, where it was previously limited to 30MHz in AV.
  • AV2 implements Multiple Input Multiple Output (MIMO) technology.

MIMO is a technology that is already deployed by the IEEE 802.11n and 802.11ac Wi-Fi standards. Similar to using multiple Wi-Fi antennas, HomePlug AV2 MIMO uses the three wires in a typical electrical outlet to simultaneously transmit more data on the different paths.

What are the advantages of Extollo’s HomePlug powerline networks?

Extollo’s HomePlug adapters are simple to use. Simply plug the adapters into an electrical outlet, connect the Ethernet cables to your digital device (rout-er, PC, STB, gaming console etc.) and a secure network has been created – “Plug and Network”. Residences often have power outlets installed in every room, cabling a computer to the powerline network can normally be done quickly anywhere in the home. Although whole-house Ethernet wiring is an option for some residences, the additional effort or cost can be high especially in larger residences. HomePlug powerline connections can also reachareas where Wi-Fi wireless signals cannot. Extollo’s HomePlug powerline networks avoid the wireless radio interference from consumer electronics that can disrupt home Wi-Fi networks. When working as designed, Extollo’s powerline connections support lower and more consistent network latency than Wi-Fi, a significant benefit for multicast IPTV, online gaming and other real-time applications.

Will noise on the powerlines affect my Extollo HomePlug network?

Generally speaking, “normal” household appliances and electronic devices will not affect the performance of Extollo’s HomePlug powerline network.Switching power supplies and adapters such as cell phone chargers, washing machines, hair dryers and air conditioners can cause noise on the power-lines. When noise is detected on the powerlines, Extollo’s HomePlug adapters modify the frequencies they transmit across, therefore avoiding the fre-quencies that are affected by noise. It is recommended that you avoid plugging in the Extollo adapter adjacent to one of the aforementioned mentioned switching power adapters.

Will the adapters affect the power in my house?

No, the electrical power grid in a house normally carries electricity at a frequency of 50 to 60 Hz. The HomePlug AV and AV2 standards use frequencies between 2 and 68 MHz, much higher than that of the power your appliances need.

Will the adapters work between different electrical phases?

Yes, for a detailed expiation read the tech note called “Home Electrical Wiring and Cross Phase Coupling Overview”.

How do I restore the device to factory defaults?

With the device plugged into an electrical outlet you will need to press and hold the Sync/Reset button on the side of the device for 15 seconds.

Why is the Power light blinking?

A blinking Power light means that your unit is in standby mode. See the product guide for a detailed overview of the LED’s.

Is my Extollo HomePlug network secure?

Extollo’s adapters employ a 128-bit AES encryption key. Data is encrypted as it is transmitted across the powerlines.

Do Extollo HomePlug adapters support QoS?

Extollo HomePlug adapters provides advanced QoS functions and features geared towards meeting the latency and jitter requirements of OTT and IPTV applications.

How many Extollo HomePlug adapters can I have connected?

Two adapters are required to form a HomePlug network. It is not recommend to have more than 16 Extollo HomePlug adapters per network.

What is the distance limitation of Extollo’s HomePlug adapters?

The maximum distance between two Extollo adapters is approximately 1,000 feet (300m). However, the maximum distance can vary from site to site based on the electrical wiring conditions and noise on the electrical power lines. The distance between adapters and noise on the power lines are factors that affect the overall performance of the HomePlug network.

Do Extollo’s adapters work when plugged into Ground Fault Circuit Interrupter (GFCI) plugs?

GFCI’s have integrated circuit switches which can affect the HomePlug’s signal strength. The reduction in signal strength may affect the adapter’s ability to communicate and form a network connection with other adapter(s) on the network.

What is nVoy?

nVoy is the certification and marketing program for the IEEE 1905.1 hybrid networking standard. HomePlug and Wi-Fi technologies are seamlessly harmonized to create a unified home network architecture.

I have an existing Extollo HomePlug network; can I add a switch to the far-end adapter?

Yes, a multiport switch can be connected to the far-end adapter to provide more network connections.

Do Extollo’s adapters work with Macs?

Yes, Extollo’s HomePlug adapters provide a seamless network experience. Any device with a standard Ethernet connection regardless of the platform type will work.
