Frequently Asked Questions
The core idea of Powerline networking is to extend Ethernet and Wi-Fi over the electrical power lines using Extollo Powerline adapters or communication modules. Similar to cable and telephone lines, electrical power lines are also capable of transmitting digital signals such as Voice, Video and Data.
Extollo specializes in Powerline technologies for home networking and industrial applications.
Our products are easy to install, simple to use and are designed using industry standards.
We focus on building the highest quality and performing Powerline products on the market. When working as designed, our products support the highest throughput and lower and more consistent network latency.
G.hn and HomePlug Powerline technologies can operate in the 2-86MHz frequencies across
the electrical power lines. Physical Layer (PHY) data rates range from 200Mbps to 2Gbps. With
Network Layer - Internet Protocol (IP) throughput rates ranging from 10Mbps to 1Gbps.
Powerline coverage and performance will vary depending on the age of your electrical home wiring, distance between the Powerline adapters, noise on the power lines and if the Powerline signal has to go from electrical phase 1 to electrical phase 2.
Yes, the real killer metric for online gamming is “application latency” - how long does it take from your input to the desired response across your home’s network. Powerline has lower latency then Wi-Fi, therefore being more responsive.
Yes, Extollo’s 2000 series of Powerline adapters uses a technique that efficiently aggregates multiple video packets which significantly increases network throughput to support Ultra-HD/4K TV’s which have higher bandwidth requirements.
Extollo supports up to 16 Powerline adapters for home networking. For industrial IoT applications, we can support up to 1,024 Powerline nodes per network domain.
Yes, a multiport switch can be connected to the far-end adapter to provide more network connections.
It depends on which product(s) you are using, typically holding the “Sync” or “Pair” button down for twenty plus (20+) seconds will reset the Powerline adapter to factory default. Please consult the appropriate product manual for complete instructions.
Yes, Extollo’s Powerline adapters provide a seamless network experience. Any device with a standard Ethernet connection regardless of the platform type will work.
G.hn is an “any wire” specification for networking. Extollo uses the G.hn standard over the
electrical power lines. The standard was developed by the International Telecommunication
Union - Telecommunication (ITU-T) the latest iteration being G.9963 ratified July 2015.
The HomePlug organization developed the Powerline Audio Video (AV1 & AV2) standards. The HomePlug organization is no longer a functioning organization. Prior to disbanding in 2016, they released all of their standards documents to other alliances and the public domain. NOTE: G.hn and HomePlug standards are not compatible.
G.hn (G.9963) is faster then HomePlug AV2. G.hn. It supports MIMO and has less overhead which results in higher IP data throughput rates.
The Powerline signal is superimposed through a coupler at a high frequency between 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 Powerline signals. Other adapters on the same power lines decouple and process the Powerline signal.
Extollo’s adapters employ a 128-bit AES encryption key. Data is encrypted as it is transmitted across the powerlines.
The maximum in home distance between two Extollo Powerline 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 Powerline network.
Generally speaking, “normal” household appliances and electronic devices will not affect the
performance of Extollo’s 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 power lines, Extollo’s Powerline adapters modify the frequencies they transmit across, therefore avoiding the frequencies 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 supplies.
Yes, for a detailed expiation read the tech note called “Home Electrical Wiring and Cross Phase Coupling Overview”.
GFCI’s have integrated circuit switches which can affect the Powerline 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.
No, the electrical power grid in a house normally carries electricity at a frequency of 50 to 60 Hz. Extollo’s Powerline products use frequencies between 2 and 68 MHz, much higher than that of the power your appliances need.
No, Una meshed Wi-Fi adapters are designed to work in conjunction with your existing router, only taking over your router's Wi-Fi duties.
First, Wi-Fi is not a network, it is a cluster of individual separate networks which allow wireless
devices network access. Wireless Access Points are aware of each other purely as interference,
and avoid one another.
Meshed wireless Access Points use special software to communicate with each other. It tells each wireless Access Point how to interact and co-ordinate traffic within the larger Wi-Fi network. The software optimizes network capacity by reducing network congestion and auto- selecting the fastest available connection and frequency band for each device. It also uses a single Wi-Fi network name (SSID) for the 2.4GHz and 5GHz frequencies.
Una uses a protocol called “Self-Organizing Networks” (SON) to manage and coordinates multiple Una’s into a single unified and intelligent Wi-Fi network that provides Wi-Fi coverage to the entire home. Wi-Fi SON monitors network conditions and Una’s self-adapt as needed. Wi-Fi SON guides smartphones, tablets, and other user wireless devices to the optimal Una, enabling a seamless experience, even when moving throughout the home.
Una Wi-Fi meshed system works a little differently. It uses your homes electrical power lines to
travel throughout the home brining a wireless signal to an area of the home where Wi-Fi
coverage is weak or non-existent.
Other Wi-Fi meshed systems use wireless repeaters to extend the Wi-Fi signal throughout the home. Wireless repeater signals can be affected by common architectural features of the home, like walls and floors which impact the wireless signal and make it more difficult to reach certain areas of the home
The HomeMesh app enables you to install and manage your Una meshed Wi-Fi System. It allows
you to monitor your home’s Wi-Fi network and make changes right from your smartphone or tablet.
It’s available for free on Apple and Google Play stores.
SSID stands for “Service Set Identifier”. A SSID is a sequence of characters that uniquely names a Wireless Local Area Network (WLAN). An SSID is sometimes referred to as a "Wi-Fi network name." This name allows wireless devices to connect to the desired Wi-Fi network when multiple networks are available in the same physical area.
Multi-user, multiple-input, multiple-output (MU-MIMO) allows a Wi-Fi Access Point to
communicate with multiple devices simultaneously. Previously, each device would communicate
sequentially. This technology is only available with 802.11ac Wave 2 wireless Access Points.
Una supports MU-MIMO.
Beamforming is an advanced algorithm which focuses the Wi-Fi signal towards the
location of the sending/receiving device. By shaping and narrowing the Wi-Fi beam in
the direction of the transmitter/receiver, it improves signal quality, extends the range
and speed, resulting in a higher quality Wi-Fi connection.
Una supports beam forming for 802.11ac devices and “implicit beamforming” for older devices.
Una’s dynamic band steering detects devices capable of using the Wi-Fi 5GHz frequency and
steers them to that frequency, this leaves the more crowded 2.4GHz band available for legacy
devices. This helps improve the user experience by reducing channel utilization, especially in
high density environments.
Una supports “Prefer 5 GHz connections” and “Load-balance connections”.
Unlike wired networks, Wi-Fi networks are susceptible to interference from neighboring wireless
networks and even noise from other RF and electronic devices.
Una’s dynamic channel selection software performs an auto-channel scan in the 2.4GHz and 5GHz frequencies and selects the best channel with the least amount of congestion and interference and assigns that channel to your Wi-Fi device. This results in a significant improvement in performance.
Have you ever wondered why certain channels in the 5 GHz band, more specifically in the 5.25-
5.35 GHz (UNII-2) and 5.47-5.725 GHz (UNII-2e) frequency bands are (almost) never in use by
Wi-Fi Access Points? These unlicensed frequency bands are also used by radar systems. So,
for a Wi-Fi Access Point to operate in one of these bands, it must support Dynamic Frequency
Selection (DFS) and TPC (Transmit Power Control).
DFS combined with TPC allows wireless Access Points to coexist with radar systems. It automatically selects a frequency that does not interfere with radar systems while operating in the 5 GHz band. If a radar system is detected, DFS and TPC will automatically adjust the channel and power output of the Wi-Fi Access Point so it doesn’t interfere with military, radar, weather station signals.
Una supports both DFS & TPC.
RSSI stands for “Received Signal Strength Indicator”. It is a measurement of the wireless signal strength between your wireless device and the Wi-Fi Access Point / router. It's a value that is useful for determining if you have enough signal to get a good wireless connection. The higher the RSSI number, the stronger the signal.
|RSSI Value||Signal Strength|
|-30 to -60dBm||Excellent|
|-60 to -70dBm||Good|
|-70 to -85dBm||Fair|
|-85 to -100dBm||Poor|
