Abstract: PROBLEM TO BE SOLVED: To constitution-revise an old transceiver so as to satisfy the request for parity, in spite of the different radiation angle in a primary state. SOLUTION: In a transceiver 1 executing radio data transmission, a transmission unit 2 and receiving unit 3 are constituted or revised to nearly equalize the radiating characteristic of a transmitter 2 and the sensitivity characteristic of a receiver 3 or at least the horizontal radiation angle of the transmitter 2 and the horizontal opening angle of the receiver. At the time of matching the radiation and opening angles at a conventional transceiver, a pipe-state light shielding part reducing the angle is used, or an additional transmission or reception constituting part is fixed so as to increase an angle generated as a result of it. By matching the radiation characteristic with sensitivity characteristic, the request for parity within the frame of a scheduled AIR standard is satisfied, and a transmitting distance is increased by nearly ten times in this manner.
