electric fields.
Step 2 Place your terminal in an open area.
Although radio signals can pass through obstacles, the transmission
effects of WLAN radio signals are affected if radio signals pass through
too many obstacles, such as cement or wooden walls.
Step 3 Place your computer close to your terminal.
If your computer is far from your terminal, the effects of the WLAN are
affected.
Step 4 Place your terminal and computer in another direction.
Step 5 Do not use your terminal to access the WLAN during thunderstorms.
After a broadband terminal is installed, does Internet access degrade call quality or
do telephone calls lower the Internet access rate?
No. The terminal uses the frequency division multiplexing (FDM) and splitter
technologies to separate voice signals from data signals. Although the two types of
signals are transmitted through one telephone line, they are carried by different
frequency bands. Therefore, they do not interfere with each other. In this case, you
can make a telephone call and access the Internet simultaneously, without degrading
call quality or lowering the Internet access rate.
