Introduction
Welcome...
to the world of 900 MHz Digital Spread Spectrum (DSS). Based on
technology originally developed for military applications, DSS provides a
level of performance for range, security, clarity over the range, and
immunity to interference that is unparalleled by any other cordless
telephone technology currently on the market.
Your Mæstro 900 DSS allows you to originate and receive calls anywhere
in your home, yard or even many blocks away from the Base. 900 MHz DSS
is the most sophisticated telephone technology available today. It provides
the ultimate in security because the voice signal is digitized and then
encoded by means of a random code that changes over time and that only
your Base and your Handset recognize. Anyone listening on a scanner hears
no intelligible signal. In addition, to increase immunity to interference, the
resulting DSS signal is not transmitted over one single frequency but instead
is transmitted over a 1.3 MHz band of frequencies.
These characteristics are what make the 900 DSS different from 900 MHz
Digital, 900 MHz Analog and 25 Channel 43/49 Mhz Analog cordless
telephones.
