5-18 Fine-Tuning Your Network
v1.0, June 2008
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.
Assessing Your 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.
• 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. Tabl e 5-2 shows the time to transfer 1 gigabyte (1 GB) of data using
various networking technologies.
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.
