Abstract: This wireless communication terminal device includes a control circuit that: causes, after receiving a beacon from a base station device, a connection to be established between the wireless communication terminal device and the base station device using a first control program; if a connection notification request to an external server was received from one or more application programs, uses a second control program, after the establishment of the connection, to output a connection establishment notification to the one or more application programs; and after the connection establishment notification is received, outputs to a communication circuit, via the first control program, a communication request to the external server device by the one or more application programs. The communication circuit of the wireless communication terminal device transmits the communication request to the base station device.

Abstract: A selection circuit selects, as anchors, at least two of a plurality of radio electronic devices and updates the selected anchors based on first information and second information, the anchors being used for position estimation for a mobile terminal, the first information being related to an arrangement of the radio electronic devices, the second information being related to a first position resulting from estimation of a position of the mobile terminal, using the selected anchors. A estimation circuit estimates the first position of the mobile terminal based on third information related to radio communication quality between the selected anchors and the mobile terminal and on the first information related to the selected anchors, and estimates a second position of the mobile terminal based on fourth information related to radio communication quality between the updated anchors and the mobile terminal and on the first information related to the updated anchors.

Abstract: A transmission device transmits multiplexed signals obtained by multiplexing signals of N systems corresponding to N Orbital Angular Momentum (OAM) propagation modes. The transmission device includes: an array antenna that includes M antenna elements disposed in a lattice on a plane when viewed from the plane; and a transmitter that multiplies signals obtained by branching each of the signals of N systems into M signals by weighting coefficients of phase shift angles based on angles of the respective M antenna elements with respect to a reference axis passing through a reference point viewed from the reference point on the plane according to the OAM propagation modes, multiplexes the signals of N systems multiplied by the weighting coefficients of the phase shift angles, and transmits signals obtained by the multiplexing from the M antenna elements. M and N are integers equal to or larger than 2.
