Frequently asked questions about the dLAN 200 AVQuestions:
Answers: Here are all of the answers for your questions related to dLAN. Question What is the maximum net data rate that dLAN 200 AV devices provide for my network applications? Answer: Depending on the protocol version used, the maximum net data rate is between 80 and 90 Mbps. As UDP has less protocol overhead than TCP, UDP can result in a slightly higher data rate than TCP. back Question How do dLAN 200 AV devices achieve a higher bandwidth than dLAN Highspeed and HP1.0 devices? Answer: dLAN 200 AV devices that comply with the HomePlug AV standard achieve higher data throughput by using a broader frequency spectrum (2-28 MHz rather than 4-21 MHz), an improved access method (TDMA—Time Division Multiple Access—rather CSMA/CD—Carrier Sense Multiple Access/Collision Detection) and a greater bitload per Hz (thanks to higher processing power) back Question: Are dLAN 200 AV devices suitable for triple play, i.e. the simultaneous use of data, voice and video applications? Answer: Yes, triple play is supported. In developing HomePlug AV, we focused specifically on the simultaneous use of multimedia applications. back Question: Can users of my dLAN network surf the Internet, play online games, use Internet telephony and watch videos at the same time? Answer: 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. back Question: 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? Answer: 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. back Question: What data transfer rates do I need for HDTV (High Definition TV)? Answer: A variety of HDTV resolutions are available. The following are the most common resolutions:
back Question: Do dLAN 200 AV devices feature security mechanisms to protect the network against intruders? Answer: Yes, of course! dLAN 200 AV devices feature AES pro 128 security. This is a combination of 128-bit triple AES encryption and a time lock when entering a new password that effectively protects your dLAN against unauthorized access. Two possible approaches are conceivable for attacks, both of which are effectively thwarted by AES pro encryption: A hacker could launch a brute-force attack to determine a suitable key with which to decrypt the data. In such an attack, all possible combinations of characters and digits in the chip are tried consecutively. Considering the range of possible keys and a maximum transfer rate of 100 Mbps between the PC and the chip (Ethernet port), a brute-force attack would take an average of 45,000 years to succeed. Another form of attack would be the interception of the encrypted raw data. An analysis of raw encrypted data would permit conclusions to be drawn about the key, thus permitting access to the unencrypted raw data. With dLAN technology, however, it is not possible to intercept encrypted raw data from the power line, as the chip does not send encrypted data directly to the network port. 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. back Question: I already use dLAN Highspeed devices in my network. Can I integrate dLAN 200 AV devices into my existing dLAN? Answer: Yes, devices based on HomePlug 1.0 and HomePlug AV standards can coexist. However, HP 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 realized with a bridge: simply plug one HomePlug 1.0 adapter and one HomePlug AV adapter into neighboring outlets and connect them with an Ethernet cable. back Question: Which operating systems are compatible with dLAN 200 AV devices? Answer: dLAN 200 AV devices are supported by Windows 98/ME/2000/XP/Vista, Linux and Mac OS-X. back Question: I'm an inexperienced PC user. How difficult is it to set up a network with dLAN 200 AV devices? Answer: 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. back Question: What kind of cables do I have to buy to connect a dLAN 200 AV to my set-top box or computer? Answer: None. All required cables are included in the package. back Question: 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? Answer: 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. back |
