MUST System - Location Based Services and Multilingual Simultaneous Transmission for Tourist Fruition

The following is a presentation of the "MUST" - Multilingual Simultaneous Transmission - system that provides
radio transmitted (PMR-PLL) audio tracks up to a distance of 100-200 meters in open areas in eight different
languages simultaneously. This innovative system, developed with a unique integration of technologies, provides
comments, descriptions, and/or background music to groups of users in various types of situations that have been
activated using LBS (Location Based System) technologies. The contents can be activated in LBS mode using GPS
technologies in open areas while in indoor environments RFID technologies are necessary. The main advantages of
this solution are: the low cost of the client devices (audio receivers), joined by the economic advantages of digital
audio track self-production; high transportability; the possibility of extending the system’s functionalities; the
high number of supported system clients: more than 100 receivers can be used simultaneously and the number of
simultaneous audio languages can be extended further. The next development of the sinchronized video streaming
functionality gives MUST more advantages and implementation possibilities.
