W.A.N.A., acronym for We Are Not Alone, is a protection system designed for users of public transport.

The project was created to combat harassment and acts of bullying on public transport, giving the possibility, especially to those who do not have the strength, to be able to report dangerous situations in real time and immediately.

This system will not be the solution to harassment but it helps in the protection and awareness of this problem.

Bluetooth wireless communications are presented as a means for creating a rapid local network independent of any other connection. This free technology is found in every mobile device, so it is excellent for communicating danger and attracting the attention of those nearby.

This technology is effective when accompanied by a targeted awareness campaign.

W.A.N.A. it makes no distinction as to who uses the system and is based only on the protection of users.
