Tour guide systems are used to help a group hear their guide's voice. Often this is because the guide may have to speak quietly in many locations; or it may be due to background noise or in larger spaces. Traditional systems require expensive receiver units which need charging, cleaning and maintenance. With LimeOnAir, the tour group just use their existing mobile phones and the LimeOnAir app.
Inside venues it's also easy to provide audio commentary... whether general, specific to certain exhibits or even audio that goes with video presentations, slide shows or pictures. Visitors can select from multiple channels simply by tapping the one they want on the app.
