A communication apparatus installed in the transportation vehicle and configured to transmit the data to the terminal existing in the transportation vehicle includes a data selection unit and an illumination unit. The data selection unit acquires location information indicating a location of the transportation vehicle in which the terminal exists and which is traveling. Based on the acquired location information, the data selection unit selects approaching-location data related to a location ahead of a current location of the transportation vehicle in a traveling direction from a plurality of pieces of data related to the location. The illumination unit transmits, as a modulated light signal, a signal comprising the approaching-location data. ## Claims ### Claim 1 A communication apparatus comprising: control circuitry which, in operation, acquires location information of a user, and acquires, based on the location information, advertisement data for a plurality of users including the user for each of a plurality of time and location resources defined by a time axis and a location zone, wherein the advertisement data may be different depending on a time and location resource; and transmission circuitry which, in operation, transmits a modulated light signal that includes the advertisement data, the modulated light signal being to be used by a terminal device to display a corresponding advertisement for the plurality of users during each of the time and location resources. ### Claim 2 (depends on 1) The communication apparatus according to claim 1, wherein the control circuitry, in operation, further acquires time information indicating a current time, and, based on the location information and the time information, acquires the advertisement data to be distributed during one of the plurality of time and location resources available in future time following the current time. ### Claim 3 (depends on 1) The communication apparatus according to claim 1, wherein the control circuitry, in operation, acquires the advertisement data by further using a location of the transmission circuitry. ### Claim 4 (depends on 1) The communication apparatus according to claim 1, wherein the transmission circuitry, in operation, transmits the modulated light signal including ID information for identifying a radio base station associated with the communication apparatus. ### Claim 5 (depends on 1) The communication apparatus according to claim 1, wherein the advertisement data is data for causing an advertisement to be displayed on a display of the terminal device that receives the modulated light signal. ### Claim 6 A communication method for a communication apparatus, the communication method comprising: acquiring location information of a user; acquiring, based on the location information, advertisement data for a plurality of users including the user for each of a plurality of time and location resources defined by a time axis and a location zone, wherein the advertisement data may be different depending on a time and location resource; and transmitting a modulated light signal that includes the advertisement data, the modulated light signal being to be used by a terminal device to display a corresponding advertisement for the plurality of users during each of the time and location resources. ### Claim 7 (depends on 6) The communication method according to claim 6, comprising: acquiring time information indicating a current time; and based on the location information and the time information, acquiring the advertisement data to be distributed during one of the plurality of time and location resources available in future time following the current time. ### Claim 8 (depends on 6) The communication method according to claim 6, comprising: acquiring the advertisement data by further using a location of the communication apparatus. ### Claim 9 (depends on 6) The communication method according to claim 6, comprising: incorporating, in the advertisement data, ID information for identifying a radio base station associated with the communication apparatus. ### Claim 10 (depends on 6) The communication method according to claim 6, wherein the advertisement data is data for causing an advertisement to be displayed on a display of the terminal device that receives the modulated light signal.
