Analog Vs. Digital Two-Way Radio

Less Power Consumption
Since digital technology uses less power than analog, battery life of the portable units is longer.
More Features
Digital 2 way radios have more features available than analog, such as simultaneous talking paths, text messaging, unit identification and status information.
Lower Threshold
Digital two-way radio receivers can operate on a weaker receive signal, and therefore will have a longer range for the same power transmitter. They will also operate in more locations where the signal may be weak.
Signal-to-Noise Ratio
Digital receivers have a better ability to pick the usable signal out of the noise that may be added to the signal once it has left the transmitter.
Error Correction
Digital receivers can further improve signal quality by electronically picking out unwanted noise from the signal, and correcting errors caused in data transmission.
