features and 
benefits
OpenSky connects seamlessly with existing applications and 
provides significant user benefits. 
OpenSky:
• Provides one communication system to many users and 
agencies maximizing inter operability. One communication 
system eliminates the need for a user to carry more than one 
radio to communicate mission critical information.
• · Allows radios to automatically roam between base stations, 
relieving radio users of the task of switching channels when 
moving to a new coverage area.
• · Offers greater system availability by providing improved 
peak traffic for all voice and data information.
• · Allows voice communication while data is being sent or 
received without having to switch radio modes.
• · Locates users quickly and accurately in an emergency using 
radios equipped with the Global Positioning System (GPS) 
option.
• · Prioritizes communications, eliminating non-essential 
information and preventing information overload.
