Imagine a tour group of 30 people.
With a traditional Tour Guide Audio System, the guide may arrive carrying 30 receivers. They need to be distributed at the beginning of the tour and collected again at the end.
But what if only 15 people actually want to listen?
Or 10?
Or perhaps only 5?
The guide still has to carry the equipment for all 30.
This is one of the less obvious inconveniences of traditional whisper systems: the equipment is there whether it is used or not.
The number of receivers a guide carries is normally determined by the size of the group, not by the number of people who actually want to use the audio.
Some tourists may prefer to stay close to the guide and hear directly.
Others may not want to carry another device during the tour.
And some may simply decide not to use the audio system at all.
The equipment, however, still has to be brought along.
For the guide, this means carrying, distributing, and collecting equipment that may spend much of the tour unused.
Poly Speaker takes a different approach.
The guide uses PolySpeaker Broadcast on their own smartphone and carries one small pocket Wi-Fi router.
The tourists use the free PolySpeaker Listener app on their own smartphones.
There is no receiver inventory to match to the size of the group.
If five people want to listen, five people use Listener.
If 20 want to listen, 20 use Listener.
If the entire group of 30 wants to listen, they can all use it.
The guide's equipment doesn't change.
With a traditional system, the operator needs to have enough receivers available for the group. The guide needs to distribute them, and the tourists need to return them.
With Poly Speaker, there is nothing to distribute.
A tourist who wants to listen simply joins the tour using their own smartphone.
Another tourist can decide not to use the audio.
And someone who changes their mind later can join.
The guide doesn't have to do anything differently.
This is perhaps the simplest way to think about Poly Speaker.
One guide. One smartphone. One pocket router.
The guide's smartphone runs PolySpeaker Broadcast. The pocket router creates the local Wi-Fi network used for communication. No internet connection is required.
The tourists use their own smartphones with PolySpeaker Listener.
Whether five, 15, or 30 tourists listen, the guide still carries one pocket router.
For a tour guide, this is more than a technical difference.
The guide's job is to lead the group, explain what they are seeing, and keep everyone together.
Managing a collection of receivers is an additional task.
Poly Speaker removes that task.
The number of people who choose to listen can change throughout the tour without changing what the guide carries.
One guide. One smartphone. One pocket router. That's the simplicity of Poly Speaker.
