Dual-Mode
The NeoPoint 1600 is a cellular band, dual-mode wireless phone, compatible with
both digital (CDMA) and analog (AMPS) networks operating at 800MHz
The term dual-mode represents the ability of your NeoPoint 1600 to transmit and
receive signals from both analog and digital cellular phone systems..
The benefits of having a dual-mode phone include being able to use your phone when
traveling and in an area where CDMA digital is not yet activated. Your NeoPoint
1600 phone will automatically find an analog cell site, allowing the call to be
processed.
About CDMA...
Code division multiple access (CDMA) is the type of digital wireless transmission
that the NeoPoint phone employs. The following sections provide information on
CDMA performance and advantages. These sections are designed to help you
understand how to better use your NeoPoint phone.
Signal Strength and Phone Performance
Like other portable wireless phones, signal strength is affected by the surrounding
environment of the user. Buildings, parking garages, elevators, and basements are
some examples of structures that reduce signal strength. Problems initializing a call,
muting of the audio during a call, or a call drop are signs of low signal strength.
Moving toward a window (if indoors) or open space (if outside) and extending the
antenna fully are ways to optimize signal strength. Traveling in a vehicle through
varying terrain, tunnels, and tall buildings may also cause rapid changes in signal
strength.
CDMA Advantages
Security Each conversation is digitized and encoded with a separate
assigned key to prevent eavesdropping.
Voice Clarity Uses digital voice coding techniques to enhance quality and
reduce background noise.
Lower Average Using sophisticated power control, the phone transmits the
