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 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.

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. 
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. 

Table 3-1

 shows the time to transfer one 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.
