802.11g). In addition, many older wireless products do not support the latest security
protocols, WPA and WPA2.
• Powerline. For 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.
• 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-speed Ethernet ports (10/100/1000 Mbps) 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.
Note: Actual data throughput will vary. Network conditions and
environmental factors, including volume of network traffic, building
materials and construction, and network overhead, can lower actual
data throughput rate.

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 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.
• 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 following table shows the time to transfer 1 gigabyte (GB)
of data using various networking technologies.
