at least one wireless transmission device located in connection with at least one people conveyer of the plurality of people conveyors, the at least one wireless transmission device configured to transmit position and/or identification data; and a mobile devices held by at least one passengers of the at least one people conveyer of the plurality of people conveyers, the mobile device configured to receive the position and/or identification data, at the mobile device, from the wireless transmission device, determine a reference position of the at least one people conveyer based on the position and/or identification data, and adopt the determined reference position of the at least one people conveyor as a reference position of the mobile device in the environment, based on a determination that a distance between the mobile device and the wireless transmission device is less than a threshold value. ### Claim 2 (depends on 1) Transportation system according to claim 1, wherein the at least one people conveyor is an elevator. ### Claim 3 (depends on 2) Transportation system according to claim 2, wherein the wireless transmission device is located at an elevator entrance or in an elevator car of the elevator. ### Claim 4 (depends on 3) Transportation system according to claim 3, wherein the wireless transmission device is configured to transmits information indicating a floor at which the elevator car is located as part of the position and/or identification data. ### Claim 5 (depends on 1) Transportation system according to claim 1, wherein the at least one people conveyor is one of, an escalator, a moving sidewalk, or a moving ramp. ### Claim 6 (depends on 1) Transportation system according to claim 1, wherein the wireless transmission device is a WLAN- or Bluetooth®. ### Claim 7 (depends on 1) Transportation system according to claim 1, wherein the wireless transmission device is located at an end of an escalator or moving sidewalk or ramp. ### Claim 8 (depends on 1) Transportation system according to claim 1, wherein the navigation system is configured to communicates with an internal sensor of the mobile device. ### Claim 9 (depends on 8) Transportation system according to claim 8, wherein the internal sensor is an accelerometer or a gyrostat. ### Claim 10 (depends on 1) Transportation system according to claim 1, wherein the wireless transmission device is a short-range transmission device. ### Claim 11 (depends on 1) Transportation system according to claim 1, wherein the wireless transmission device is integrated in a structure of an elevator car or in a door jamb of a landing or car door of an elevator. ### Claim 12 (depends on 1) Transportation system according to claim 1, wherein the wireless transmission device is integrated in a structure of an escalator or moving sidewalk or ramp. ### Claim 13 (depends on 1) Transportation system according to claim 1, wherein the mobile device is a mobile phone. ### Claim 14 (depends on 1) Transportation system according to claim 1, wherein the wireless transmission device is located in an operating panel of an elevator. ### Claim 15 A method, comprising: receiving position and/or identification data, at a mobile device, from a wireless transmission device, the wireless transmission device located in connection with a people conveyer; determining, at the mobile device, a reference position of the people conveyer in an environment based on the position and/or identification data, and adopting the determined reference position of the people conveyor as a reference position of the mobile device in the environment, based on a determination that a distance between the mobile device and the wireless transmission device is less than a threshold value. ### Claim 16 (depends on 15) The method according to claim 15, wherein the people conveyor is an elevator. ### Claim 17 (depends on 16) The method according to claim 16, wherein the wireless transmission device is located at an elevator entrance or in an elevator car of the elevator. ### Claim 18 (depends on 17) The method according to claim 17, wherein the position and/or identification data includes information indicating a floor at which the elevator car is located. ### Claim 19 (depends on 15) The method according to claim 15, wherein the people conveyor is one of, an escalator, a moving sidewalk, or a moving ramp. ### Claim 20 (depends on 15) The method according to claim 15, wherein the wireless transmission device is located at an end of an escalator or moving sidewalk or ramp.
