Features of Analog
- As signal weakens, so does audio quality as static increases
- Not feature rich. Analog is pretty much limited to push-to-talk, scanning, simple group conversations (one-to-many), and limited encryption capabilities without involving some very creative and often unreliable design.
- It does not use frequencies as efficiently as can be done using digital.
Features of Digital
- When the signal is strong, the sound is clear and crisp. This clarity increases the effective range of the radio by around 5%
- If the signal is weak, it is likely to be lost completely. However, the audio is clear up until the moment it is lost.
- Not all digital broadcasts are compatible with each other. Your choices of manufacturers may be limited.
- New features such as enhanced text messaging, IP connectivity, GPS, 1 to 1 communications, and other data transmissions
Trunking allows for customers to pool their frequencies/talk paths and share them with multiple talk groups, rather than the less efficient traditional method of assigning each talk group to their own dedicated frequency/talk path. Digital technology allows for advanced features like GPS & text messaging to be efficiently integrated into a radio system.
Frequency and WiFi, All-in-one
Recently manufacturers have begun production of devices using the traditional 2-Way radio form factor (rugged and user-friendly) that operate on WiFi networks. We now have dual band radios that will be able to use traditional frequency bands (UHF/VHF/800MHz) as well as WiFi, all in one device [Icom IP100]
Call boxes are durable fixed mounted radios that have a loud speaker. Some popular solutions using call boxes are golf courses, school emergency solutions, security gates, and man lifts on construction job sites. [Ritron]
