How to Build a 100m Range Radio Transmitter with Multiple Receivers for Conference Room

A radio transmitter system with a 100-meter range suitable for a conference room environment is feasible. The design depends on specific requirements such as data transfer volume, frequency, number of receivers, power consumption, and device size. For a one-to-many audio transmission scenario without security needs, low-cost 433 MHz RF modules are recommended as a simple solution. Bluetooth technology is an alternative, having been used in similar applications for streaming audio based on language preference, but it may incur higher costs due to the need for multiple Bluetooth receivers. The system aims to transmit live audio from an existing device to multiple receivers functioning as language translators for the audience.
