Language interpretation
Language interpretation service is providing a interpreter who converts a thought or expression in a source language into an expression with a comparable meaning in a target language either simultaneously in "real time" or consecutively when the speaker pauses after completing one or two sentences.

Step 1: The speaker of the floor language talks into a microphone (this is called the floor mic or the floor feed).
Floor feed is broadcast to interpreter
Step 2: The floor feed is broadcast (usually wirelessly) to the interpreter, who listens through headphones in a separate location – this is usually in a soundproof booth at the back of the room, or sometimes in a separate room.

Step 3: The interpreter listens to the floor feed and simultaneously speaks into a microphone, which is broadcast wirelessly to the audience, who wear specialized headphones so they can hear the proceedings in their native language.

System Types and the Pros and Cons of Each
Infrared Systems
WIR SYS 7518 Mid-Range interpretation system from Williams Sound
Using the same technology as your TV remote control, infrared interpretation systems transmit the translation feed to the audience using invisible pulses of light.
Members of the audience listen to the audio feed in their native language using specialized multi-channel receivers with headphones.
Some key points about Infrared systems:
Medium Range Handheld Digital Systems
Ultra-Portable 4-Person Digi-Wave Interpretation System (Williams Sound)
FM interpretation systems use radio waves to send the translation feed to the audience. Members of the audience use multi-channel receivers equipped with headphones so they can listen to the speaker in their native language.
Some key points about these systems:
Longer Range Portable FM Systems
PPA 377 Four-Person System (1000 foot range) – Williams Sound
If you have a larger area to cover, then you’ll need more powerful FM translation equipment. These systems can broadcast the translation feed over distances exceeding 1000 feet. But the added power means that the machines are less portable. They are certainly portable, but just require a bit more in terms of set-up and take-down.
