The wiring is exempt from cost advantages, convenient installation, later
extended easily -- only increase system transmission power and increase the
terminal. Defect is low anti-interference capability, with the passage of time
and the surrounding environment changes, such as temperature, humidity, etc.),
electronic components will continue to aging, electrical parameters are big or
small change, especially the resistance and capacitance (frequency changes
precisely the inseparable relations) so in the long run, to ensure reliability
and radio is quite difficult for.
