Why Digital Two Way ?

 |
|
| Clearer voice
communications over a greater range.
When signal strength drops off with distance, digital
error-correction technology can accurately deliver both
audio and digital content with virtually no loss over a far
greater area. |

|
| Static
and noise rejection.
Analog signals become distorted, producing audible static as
signal strength degrades. By contrast, digital receivers
simply reject anything they interpret as an error. TDMA
divide power-intensive transmissions into two independent
time slots. That means each individual transmission only
uses half the battery power of an analog system transmitting
at the same wattage. |

Additional
functionality.
Digital systems based on TDMA divide power-intensive
transmissions into two independent time slots. That means
each individual transmission only uses half the battery
power of an analog system transmitting at the same wattage.
Since transmitting is the most energy-intensive operation,
digital two-way radios can typically function 40 percent
longer between recharges compared to analog radios.

|
Additional
functionality.
Digital two-way radio systems based on TDMA can provide
additional features beyond two-way voice by using the second
time slot for a second call, dispatch data, enhanced call
signaling and control for future enhancements such as
emergency pre-emption. |
