dLAN® 200 Mbps



Are devolo dLAN® HS devices "triple play" compatible?

Yes, in every respect.
Up


Are dLAN® 200 AV devices suitable for triple play, i.e. the simultaneous use of data, voice and video applications?

Yes, triple play is supported. In developing HomePlug AV, we focused specifically on the simultaneous use of multimedia applications.
Up


Are standard 100 Mbps network adapters fast enough for devolo dLAN® 200 AV adapters, or are Gigabit Ethernet adapters required for use with dLAN® 200 AV adapters?

Under ideal conditions, devolo dLAN® 200 AV adapters have a physical gross data rate of up to 200 Mbps. The effective net data rate is somewhat lower. A 100-Mbps network adapter is therefore adequate in most cases to operate the devolo dLAN® 200 AV adapter.

Can users of my dLAN® network surf the Internet, play online games, use Internet telephony and watch videos at the same time?

Yes. The high data rate and reliable Quality-of-Service (QoS) functions supported by devolo dLAN® 200 AV devices are the basis for the simultaneous use of triple-play multimedia applications.

Do dLAN® 200 AV devices feature security mechanisms to protect the network against intruders?

Yes. of course! dLAN® 200 AV devices feature AES 128 security. This is a combination of 128-bit AES encryption and a time lock when entering a new password that effectively protects your dLAN® against unauthorised access. Two possible approaches are conceivable for attacks, both of which are effectively thwarted by AES pro encryption: A brute force attack could be launched in order to find the key for decrypting the data. In such an attack, all possible combinations of characters and digits in the chip are tried consecutively. However, given the variety of the keys and a maximum transfer rate between the PC and chip of 100 Mbps (Ethernet interface), a brute force attack of this kind would, on average, take 45,000 years to succeed. Another form of attack would be the interception of the encrypted raw data. The encrypted raw data could provide clues to the key, thus allowing access to the unencrypted raw data. In dLAN® technology, however, it is not possible to intercept the encrypted raw data from the electrical wiring, as the chip does not send encrypted data directly to the network interface. The chip not only encrypts the signal, but also modulates it directly, ensuring that it is only possible to intercept modulated data. That would be pointless, however, as an attacker would not have any way to demodulate the data.

Does the technology also support multicast video server streams (IPTV)?

Yes!

How can I ensure that the dLAN® will have enough bandwidth for my sensitive HDTV video applications when large volumes of data are being transferred within the network at the same time? Is there a Quality of Service feature?

Yes. Devices that comply with the HomePlug AV standard feature Quality-of-Service (QoS) functions. The necessary settings are made by the connected network devices such as computers, set-top boxes, game consoles and VoIP telephones and supported by the dLAN® 200 AV devices. The devices themselves do not require any configuration by the user.
Up


How do dLAN® 200 AV devices achieve a higher bandwidth than dLAN® Highspeed and HomePlug 1.0 devices?

The dLAN® 200 AV devices that use the HomePlug AV standard attain higher data throughput by: using a wider frequency spectrum (2-30 MHz instead of 4-21 MHz), more bits per carrier. 
Up


How do I prevent someone else (such as a roommate) from buying a dLAN® adapter and intercepting data transfer between my dLAN® adapters?

Using the device's internal encryption, which is enabled using the software provided.
Up


How does power-save mode work? How much savings does power-save mode provide?

If the adapter does not detect any USB voltage or Ethernet link, such as when the connected computer is switched off or in standby mode, the adapters switch to power-save mode and use approx. 30% less energy.
Up


How secure are my data? Can they be intercepted in any way?

We recommend that you always use the device's internal encryption. Enable it by entering a password other than the factory password.
Up


I already use dLAN® Highspeed devices in my network. Can I integrate dLAN® 200 AV devices into my existing dLAN®?

Yes, devices based on HomePlug 1.0 and HomePlug AV standards can coexist. However, HomePlug 1.0-compatible devices cannot exchange data directly with dLAN® 200 AV devices. Data communication between HomePlug 1.0 and HomePlug AV networks can be realised with a bridge: simply plug one HomePlug 1.0 adapter and one HomePlug AV adapter into neighbouring outlets and connect them with an Ethernet cable.
Up


I am looking for a dLAN® repeater to increase the range of the dLAN® network. Do you offer such a product?

You can increase the range by combining two dLAN® networks with two different dLAN® passwords. The repeater function is implemented by two standard dLAN® Ethernet adapters, which you can easily connect using an Ethernet cable. When doing so, keep in mind that you are still using only one physical medium, i.e. the bandwidth is split between the two networks. You can repeat this procedure more than once.
Up


I am not computer savvy. How difficult is it to set up a network with dLAN® 200 AV devices or high-speed adapters?

Unpack them, plug them in, and you have a network! Even the most inexperienced users can set up a dLAN® network with ease. No installation is required—just plug and play. The simple configuration software is only needed when assigning passwords to protect the network against intruders.
Up


Is it possible to transmit high-resolution videos using high-speed adapters?

Yes, in full DVD quality.
Up


What data transfer rates do I need for HDTV (High Definition TV)?

"Various HDTV resolutions exist. The following are the most frequently used resolutions:
720p, mpeg2: 09-10 Mbps
720p, mpeg4: 06-08 Mbps
1080i, mpeg2: 12-15 Mbps
1080i, mpeg4: 08-10 Mbps
"
Up


What is the maximum net data rate that dLAN® 200 AV devices provide for my network applications?

Depending on the protocol version used, the maximum net data rate is between 65 and 90 Mbps. As UDP has less protocol overhead than TCP, UDP can result in a slightly higher data rate than TCP.
Up


What kind of cables do I have to buy to connect a dLAN® 200 AV to my set-top box or computer?

None. All required cables are included in the package.
Up


Which operating systems are compatible with dLAN® 200 AV devices?

dLAN® 200 AV devices are supported by Windows 98/ME/2000/XP/Vista, Linux and Mac OS-X.
