and Electronics Engineers) Standards Committee. Each of these wireless technologies
and standards provides a specific connection method or way of transferring data over
your home wireless network. The 802.11b and 802.11g standards use the 2.4/2.5 GHz
radio frequencies, and have average connection speeds of 4.5 Mbit/s (1 million bits per
second) and 20 Mbit/s respectively. The newest standard 802.11n uses both the 2.4 GHz
and the 5.0 GHz radio frequencies, and has an average connection speed of 74 Mbit/s,
making it the choice for fast wireless connections. Though the latest standard 802.11n
standard has not been fully ratified, it does exist in draft form and products exist that can
be used for home networking. Because 802.11n uses the 5.0 GHz frequency band, it can
avoid many interference effects from home appliances and neighboring wireless networks.
Can other home electrical products interfere with my Powerline adapter or Wireless
bridge?
Yes, depending on the type of product used, such as a microwave oven, a vacuum, a hair
dryer, or cordless home phone you may experience a reduction in the connection speed of
your home powerline network or wireless network when you use certain home appliances
while using your BRAVIA Internet Video Link. Some home appliances operate at the
same frequencies or close frequencies to your home networking devices, and thus the
wave signals can “bounce” off each other causing a slower connection speed. This
“noise” is common among home networks, though many networking devices have ways
of filtering out much of the interference to compensate for the signal degradation.
Examples of these are powerline devices that “hop” frequencies that are congested, and
wireless MIMO (multiple-in, multiple-out) technologies that send data over many radio
frequencies at once.
Can my powerline adapters interfere with my lighting or electrical home products?
Yes. Depending on the type of lighting or lamps that you have in your home, and if you
have a dimmer switch or touch-sensitive on/off switch that sends or receives data signals,
you may experience interference with that function when using your powerline devices.
Some home electrical products send or receive data signals at higher frequencies as part
of their control features. These signals may also be used by powerline adapters, and the
resulting signal noise can temporarily affect performance.
Can I plug my powerline adapter into a power strip or surge-protector?
We do not recommend that you plug your powerline adapters into a power strip or surge-
protector because the throughput or speed of your connection can be significantly
reduced using this method. Most power strips or surge-protectors have noise filters
which affect the quality of the powerline signal. Moreover, as with all networking
connections there is the potential for interference with the signal that is received by the
Ethernet cable. Therefore, we recommend that powerline adapters be plugged directly
into the nearest wall power outlet, unless your power strip brand clearly states that it is
compatible with powerline technology.
