The invention regards to a local navigation system comprising:

a plurality of beacons located in a local environment and being configured to send signals specified to different routes in said local environment;

a plurality of mobile devices, each of them comprising: a client control means,

a wireless communication link configured to receive the signals sent by the beacons;

an output means configured to display/emit navigation guide data;

in which local navigation system the client control means is configured to process the signals received via the wireless communication link and to process this data into navigation guide data outputted on output means of the mobile device,

whereby each route comprised in the local environment is assigned a unitary ID

and whereby each beacon is located in one specific location of the local environment along at least one of said routes, whereby each beacon is configured to send the IDs of all the routes passing along its specific location,

whereby the client control means obtains the route ID to a chosen destination from a destination input device of the local navigation system and/or of the mobile device, and which client control means is configured provide said navigation guide data in interaction with the beacons sending said route IDs of the chosen location. This system allows anonymous navigation in the local environment, possibly in a decentralized system without centralized or wired system components.
