Title:
NETWORK SYSTEM
Document Type and Number:
Japanese Patent JP3423107
Kind Code:
B2
Abstract:
PURPOSE: To avoid a distance problem in CDMA by constituting an equal distributed network without requiring complicated transmission power control.
CONSTITUTION: Respective subnetworks are expressed by G1 to G3 and a subnetwork G4 is constituted of one station. The subnetworks G1 to G4 respectively execute spread spectrum communication by using PN2, PN3 and PN4 and each subnetwork multiplexes its own lines by CSMA. When diffusion codes used in respective subnetworks are made different from each other, interference applied to communication between respective subnetworks can be reduced and the communication of each subnetwork can be independently executed.
