MBC D5, D6 public hall has changed their old 2.4GHz wireless intercom to Genie. The system includes 2 Base Stations, 7 Antennas and 28 wireless beltpacks. With only 2 base stations and synchronised connection of the two, and with 7 additional antennas under each base station as well, all the teams can have separate group wireless communications in the two large public halls and hallways. All the 28 beltpacks can also be connected to any antenna at once and have communications.
