摘要： A PDC/PHS phone has both PDC communication function and PHS communication function. The PDC/PHS phone switches its communication mode from a PDC communication to a PHS communication which is less power consuming than the PDC communication, when its built-in battery runs down to a reference level in the course of communication with another phone. The PDC/PHS phone switches its communication mode back to the PDC communication again, when the battery is recharged enough.

摘要： It is determined whether each of several subcarriers has an adequate propagation characteristic in a first horizontally polarized wave antenna. Of the several subcarriers, a subcarrier, which is determined to have an adequate propagation characteristic in the first horizontally polarized wave antenna, is assigned with transmission data. A transmission signal containing the transmission data is thereby transmitted from the first horizontally polarized wave antenna. In addition, of the several subcarriers, a subcarrier, which is determined not to have an adequate propagation characteristic in the first horizontally polarized wave antenna, is also assigned with transmission data in either a second horizontally polarized wave antenna or a vertically polarized, wave antenna. A transmission signal containing the transmission data is thus transmitted from the second horizontally polarized wave antenna or the vertically polarized wave antenna.

摘要： A planar antenna is disclosed. The planar antenna includes: a radiator element having a wideband resonant characteristic; and a parasitic element having a planar shape. The parasitic element has a first side, a second side, a third side and a fourth side. Each of the first side and the second side is parallel to a direction of an electric current to be excited in the radiator element. The first side is located closer to the radiator element than the second side is. The first side is shorter than the second side. The third side connects one ends of the first side and the second side. The fourth side connects the other ends of the first side and the second side. A region between the third and fourth sides tapers in a direction from the second side toward the first side.

摘要： An on-board communication equipment on each of two vehicles receives a radio wave from two or more GPS satellites, and determines a carrier wave phase of the received radio wave. Then, the on-board communication equipment on one vehicle receives, from the other vehicle, information on the carrier wave phase observed in the other vehicle. Further, the on-board communication equipment calculates a relative position of a self vehicle relative to the other vehicle by a Carrier-Phase DGPS positioning based on a difference between two carrier wave phases (e.g., single difference, double difference or the like), that is, one from the self vehicle and one from the other vehicle, both having the same observation time, from among the available carrier wave phases.

摘要： A vehicle device for use in vehicle-roadside communication that communicates with a roadside device disposed on a roadside includes a radio unit for receiving an informational message from the roadside device as well as a display and a speaker for information provision. The vehicle device further includes a storage unit for storing the informational message received by the radio unit. A system controller in the vehicle device determines whether information provision condition for providing the informational message in the storage unit is met based on an information content and current condition information in the informational message received by the radio unit. When the information provision condition is determined to be met, the system controller controls the display and the speaker to cause a provision of the informational message.

摘要： An antenna system for use in a wide frequency band has a reflection board that has a board shape with an outer edge and an inner edge. The antenna system connects the reflection board and an antenna module in a manner that does not allow a flow of a direct current. Further, a dimension of the reflection board along a polarization direction of the antenna module has a value that is equal to or greater than a product of a maximum wavelength of a usable frequency band multiplied by a wavelength reduction rate of a dielectric material.

摘要： A mobile station requests a start of positioning and receives a response of positioning from a positioning server, following which it informs the positioning server of its own station information and neighboring base station information gathered through searching the neighboring base stations. Thereby, the mobile station receives assistant information regarding GPS satellites to be captured based on a station location designated by the positioning server and then it measures a GPS signal and a base station signal such as an apparent signal delay. In the case that the positioning information collected as described above is sufficient for location computing, it displays the location computed by the positioning server. In contrast, in the case that the positioning information is insufficient, it displays “positioning impossible” without sending the positioning information to the positioning server.
