Abstract

PURPOSE:To surely communicate a data to a remote location by relating and sending a same data as a reception data based on the result of identification of the reception data. CONSTITUTION:When transceiver sections 4a-4c receive a radio wave, a same data as a received data is relayed and sent based on the result of identification of the data received by a relay means (comprising of a relay transmission discrimination section 1a, a radio module section 2 and an antenna 3 or the like). Then the data received by the transceiver sections 4a-4c being objects sequentially are relayed and sent. Thus, a data is identified and sent to an object transmission destination even at a low output by relaying and sending the data to other portable radio equipment resident nearby while the radio wave sent in the vicinity is received and the received destination is being identified.

A portable wireless device according to the present invention is provided with a relay means for relaying and transmitting data identical to the received data based on the identification result of the received data.

In addition, the transmission relay method divides the transmission area into relay areas based on the transmission power, and transmits received data to the adjacent relay area via the transceiver section of each mobile radio device that is installed in a single relay area. Send.

[Operation] In the present invention, when each transceiver unit receives a radio wave, the relay means relays and transmits the same data as the received data based on the identification result of the received data, and sequentially receives the data to the target transceiver unit. The data will be relayed and transmitted.

In addition, in the transmission relay method, the transmission area is divided into relay areas based on the transmission power, and the transceiver section of each portable wireless device is arranged in a single relay area.
The received data is transmitted to the adjacent relay area via each transceiver unit.

[Embodiment] FIG. 1 is a block diagram illustrating the configuration of a portable wireless device showing an embodiment of the present invention, in which numeral 1 denotes a control unit including a ROM and a RAM (not shown), and a control program stored in the ROM. Data transmission and reception processing is controlled based on the data transmission and reception processing. 4a
2 is a transceiver section, and as shown in FIG. 2, which will be described later, the transmission area TME is arranged in a relay divided area DIVE set based on the transmission power of each transceiver section 4a to 4c. It is assumed that the transmission power of each transceiver unit 4a to 4C is a transmission capability that covers twice the diagonal distance of each area.

2 is a wireless module section that modulates the output data output from the control section 1 and emits radio waves from the antenna 3;
It receives radio waves emitted from nearby transceiver sections 4b and 4c, demodulates the received radio waves, and outputs received data to relay transmission determination section 1a of control section 1. Note that the configurations of the transceiver sections 4b and 4c are similar to the transceiver section 4a.

The relay transmission determining unit 1a analyzes the received data to determine whether the destination matches a preset identification code, and if so, further processes the data.

On the other hand, if the identification code does not match the identification code set on the RAM, the received data is determined to be relay data, and the same data as the received data is sent to the wireless module unit 2.
and relays radio waves modulated based on the same data to nearby transceiver units 4c and 4b via the antenna 3.

In the portable wireless device configured in this way, when each transceiver section 4a to 4c receives a radio wave, the relay means (in this embodiment, the relay transmission determination section la, the wireless module section 2
