January 29, 2008 Statement of Conditions In the interest of improving internal design, operational function, and/or reliability, NETGEAR reserves the right to make changes to the products described in this document without notice. [. . . ] NETGEAR's Powerline HD family of products delivers up to 200 Mbps to any power outlet, and connects to your devices and network using standard Ethernet cables. Note: You need at least two Powerline HD adapters to make this type of connection in your network. · · 5-7 Data transmissions are encrypted for security, and you can configure an individual network password to prevent neighbors from connecting. The Powerline HD family of products can coexist on the same network with older generation XE family products or HomePlug 1. 0 products, but they are not interoperable with these older products. · Wired Ethernet As Gigabit Ethernet ports become common on newer computers, wired Ethernet remains a good choice for speed, economy, and security. Gigabit Ethernet can extend up to 100 meters with twistedpair wiring of CAT-5e or better. A wired connection is not susceptible to interference, and eavesdropping would require a physical connection to your network. Assessing Your Speed Requirements Because your Internet connection is likely to operate at a much lower speed than your local network, faster local networking technologies may not improve your Internet experience. For example: · Streaming HD video requires 10 to 30 Mbps per stream. Because latency and packet loss can disrupt your video, plan to provide at least twice the capacity you need. · Streaming MP3 audio requires less than 1 Mbps per stream and does not strain most modern networks. Like video, however, streaming audio is also sensitive to latency and packet loss, so a congested network or a noisy link can cause problems. · Backing up computers over the network has become popular due to the availability of inexpensive mass storage. The table below shows the time to transfer one gigabyte (1 GB) of data using various networking technologies. Table 5-1.

Network conditions and environmental factors, including volume of network traffic, building materials and construction, and network overhead, can lower actual data throughput rate. Optimizing the Performance of Your Home Network To get the best performance from your home network, you should optimize each portion of the network, as well as place files in the network where they will get the bandwidth their use will demand. 5-9 Optimizing Wireless Performance The speed and operating distance or range of your wireless connection can vary significantly based on the physical placement of the wireless router. You should choose a location for your router that will maximize the network speed. Tip: To find the best location, start the Network Test (on the Supervisor functions menu) running on the Digital Entertainer HD, and then move the Digital Entertainer HD, the antenna on the Digital Entertainer HD, and the wireless router. Monitor the Network Test results, to determine which location maximizes network speed. Note: Failure to follow these guidelines can result in significant performance degradation or inability to wirelessly connect to the router. For complete range and performance specifications, please see "Technical Specifications" in Appendix A. The following list describes how to optimize wireless router performance. If your network has several wireless devices, decide which wireless devices need the highest data rate, and locate the router near them. Many wireless products have automatic data-rate fallback, which allows increased distances without losing connectivity.
