Problems solved by technology

[0009] In addition, in the case of broadcast communication, since delivery confirmation is not performed, the transmission source DTE (ID=0) does not detect or retry the loss of transmission data in the wireless section despite the possibility of transmission data loss. Error control such as calculation processing, therefore, the reliability of packet transmission is low
[0010] In addition, the delivery confirmation and error control of the sent data become the responsibility of the sending source DTE (ID=0). In this way, the sending source DTE must use software processing to cover the wireless interval. The portion where the line quality in the wireless section deteriorates, which increases the burden on the transmission source DTE

Embodiment Construction

[0035] Hereinafter, details of the present invention will be described based on the embodiments shown in the drawings.

[0036] The communication system shown in Fig. 1 connects the transmission source DTE (ID=0) and a plurality of transmission destination DTEs (ID=1) (ID=2) (ID=3) ( ID=N) are concatenated. The installed number of destination DTEs is not limited to this range. In addition, DTEs can be arbitrarily sent as a source or as a destination. Therefore, these DTEs can both send and receive packets, and serve as both a source and a destination at the same time. In addition, since the internal circuit of the DTE is well known, its illustration is omitted, but the above-mentioned circuit is equipped with a computer, and at the same time, it is installed with communication software for communication protocol processing and other processing necessary for packet transmission in the communication system. These are the same as the communication system of FIG. 2 .

Abstract

There are provided a radio communication device and a communication system using the same wherein the probability of packet collision is reduced without modification of DTE-side communication software in a communication system that performs radio transmission of packets from a source DTE to a plurality of destination DTEs. In a radio communication device to be used in a communication system for performing radio transmission of packets including destination address between a source DTE and a plurality of destination DTEs its own address in a communication system is set identical to an address of the DTE, interpretation is carried out as to whether a destination address included in a command received from an arbitrary radio communication device is the own address or an address of a different radio communication device, and packet transmission is then performed corresponding to the interpretation.

Description

technical field [0001] The present invention relates to a wireless communication device and a communication system using the wireless communication device, in particular to a method of transmitting information packets from a transmission source DTE (digital terminal) to a plurality of transmission destination DTEs via interconnected wireless communication devices Communication Systems. Background technique [0002] In the case of the communication system shown in FIG. 7, the transmission source DTE (ID=0) and the transmission destination (ID=1) (ID=2) (ID=N) are connected to each other by wire. Furthermore, when a packet is transmitted from the source DTE (ID=0) to each destination DTE (ID=1) (ID=2) (ID=N), the destination DTE (ID=1) ( ID=2) (ID=N) judge whether the sending destination address of the instruction contained in this information packet is the address of this machine; If it is the address of this machine, then carry out the reading-in of the data contained in th...
