3-1v1.0, December 2009Chapter 3 Wireless Network PerformanceThis chapter explains how to use your wireless-N USB adapter to connect to your wireless local area network (WLAN) and how to maximize the performance of your wireless-N USB adapter within your network. Included are scenarios for setting up your network in a mixed-use environment and the trade-off of using different types of technology—wireless, wired, Powerline, and so on. Optimizing Wireless PerformanceThe speed and range of your wireless connection can vary significantly based on the location of the wireless router. You should choose a location for your router that maximizes the network speed.The following list describes how to optimize wireless router performance.• Identify critical wireless links.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 loss of connectivity. This also means that devices that are farther away might be slower. Therefore, the most critical links in your network are those where the traffic is high and the distances are great. Optimize those first. • Choose placement carefully. For best results, place your router:– Near the center of the area in which your computers will operate.– In an elevated location such as a high shelf where the wirelessly connected computers have line-of-sight access (even if through walls).• Avoid obstacles to wireless signals.– Keep wireless devices at least 2 feet from large metal fixtures such as file cabinets, refrigerators, pipes, metal ceilings, reinforced concrete, and metal partitions.– Keep the devices away from large amounts of water such as fish tanks and water coolers.• Reduce interference.Avoid windows unless communicating between buildings.Place wireless devices away from various electromagnetic noise sources, especially those in the 2400–2500 MHz frequency band. Common noise-creating sources are:
Wireless-N 300 USB Adapter WNA3100 User Manual3-2v1.0, December 2009– Computers and fax machines (no closer than 1 foot)– Copying machines, elevators, and cell phones (no closer than 6 feet)– Microwave ovens (no closer than 10 feet)• Choose your settings.– Use a scanning utility to determine what other wireless networks are operating nearby, and choose an unused channel.– Turn off SSID Broadcast, and change the default SSID. Other nearby devices might automatically try to connect to your network several times a second, which can cause significant performance reduction. Optimizing Your Network BandwidthThe speed of network connections depends on the type of equipment that you use. Try to use high-speed technologies for network connections with the heaviest traffic to avoid lower-speed bottlenecks in the path. Figure 3-1 on page 3-3 shows a home network that includes many different connection speeds.In this network, the two computers with gigabit Ethernet adapters have a gigabit connection through the router to the storage server. With a high-speed router this connection allows for extremely fast backups or quick access to large files on the server. The computer connected through a pair of Powerline HD adapters is limited to the 200 Mbps speed of the Powerline HD connection. Although any of the links in this example would be sufficient for high-traffic applications such as streaming HD video, the use of older devices such as 10 Mbps Ethernet or 802.11b wireless would create a significant bottleneck.
Wireless-N 300 USB Adapter WNA3100 User Manual3-3v1.0, December 2009In planning your network, think about which tasks will have the heaviest traffic flow between them. Examples are:• A media center in one room streaming high-definition video from a server in another room• A storage device that is used for backing up your computersSmall Office and Home Office (SOHO) Networking TechnologiesCommon connection types and their speed and security considerations are:•Broadband InternetYour Internet connection speed is determined by your modem type, such as ADSL or cable modem, the connection speed of the sites to which you connect, and general Internet traffic. ADSL and cable modem connections are asymmetrical, meaning they have a lower data rate to the Internet (upstream) than from the Internet (downstream). Keep in mind that when you connect to another site that also has an asymmetrical connection, the data rate between your sites is limited by each side’s upstream data rate. A typical residential ADSL or cable modem connection provides a downstream data rate of about 1 to 3 megabits per second (Mbps). Newer technologies such as ADSL2+ and Fiber to the Home (FTTH) l increase the connection speed to tens of Mbps.Figure 3-1
Wireless-N 300 USB Adapter WNA3100 User Manual3-4v1.0, December 2009•WirelessA high-speed wireless router can provide a wireless data throughput of up to 300 Mbps using technology called multiple-input multiple-output (MIMO), in which multiple antennas transmit multiple streams of data. The use of multiple antennas also provides excellent range and coverage. With WPA and WPA2 encryption and authentication protocols, wireless security is extremely strong.To get the best performance, use newer adapters such as RangeMax adapters for your computers. A high-speed router might be compatible with older 802.11b and 802.11g adapters, but the use of these older wireless technologies in your network can result in lower throughput overall (typically less than 10 Mbps for 802.11b and less than 40 Mbps for 802.11g). In addition, many older wireless products do not support the latest security protocols, WPA and WPA2.•PowerlineFor connecting rooms or floors that are blocked by obstructions or are distant vertically, consider networking over your building’s AC wiring. NETGEAR’s Powerline HD family of products delivers up to 200 Mbps to any outlet, while the older-generation XE family of products delivers 14 Mbps or 85 Mbps. Data transmissions are encrypted for security, and you can configure an individual network password to prevent neighbors from connecting.When you add new Powerline products, you can continue to use older models, but they might not be able to share the same Powerline network.•Wired EthernetAs 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 twisted-pair 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 Network Speed RequirementsBecause your Internet connection is likely to operate at a much lower speed than your local network, faster local networking technologies might not improve your Internet experience. However, many emerging home applications require high data rates. 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.Note: Actual data throughput varies. Network conditions and environmental factors, including volume of network traffic, building materials and construction, and network overhead, can lower actual data throughput rate.
Wireless-N 300 USB Adapter WNA3100 User Manual3-5v1.0, December 2009• 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.
