A broad band packet radio communication system is characterized by the carrier sense multiplexing connection method operated on a harsh frequency arrangement where an occupied band width of a modulation transmission/reception wave and a modulation side lobe are wide and the frequency channel interval is narrow. It is possible to improve the reception adjacent channel interference characteristic among a plurality of terminals belonging to the respective cells existing in the vicinity of adjacent frequency cell boundary area. The RSSI system is subjected to a narrow-band channel filtering (a narrow-band filter (BPF or LPF) having a band narrower than one-channel occupied band width) while the reception/demodulation system is subjected to a wide-band channel filtering (a wide-band filter (BPF or LPF) having a pass band equal to or wider than the one-channel occupied band width).

Ce système de communication radio à large bande par paquets se caractérise par le fait que la méthode de connexion par multiplexage de détection de porteuse fonctionne sur une fréquence dure. La largeur de bande occupée d'une onde d'émission/réception en modulation et un lobe latéral de modulation sont larges alors que l'intervalle de canal de fréquence est étroit. Il est possible d'améliorer les caractéristiques de réception du brouillage entre canaux adjacents parmi plusieurs terminaux appartenant à des cellules respectives existant au voisinage des zones de limite des cellules. Le système RSSI est soumis à un filtrage à bande de transmission étroite (filtre à bande de transmission étroite ÝBPF ou LPF¨ dont la bande est plus étroite que celle de la bande occupée par le canal) alors que le système de réception/démodulation est soumis à un filtrage de canal large bande (filtre à bande de transmission étroite ÝBPF ou LPF¨ ayant une bande passante égale ou supérieure à celle de la largeur du canal occupé).
