ABSTRACT:
The present invention relates to a high-speed high-capacity Local Area Network (LAN) wherein each user, of a separate group of one or more of the network users, communicates cordlessly, using radio frequencies or infrared, with an assigned Regional Bus Interface Unit (RBIU) located in the proximity of the group. Each RBIU of the network interfaces with a high-speed serial or lower speed parallel bus of an open-ring network for purposes of transmitting information signals while receiving information signals via the high-speed serial network bus (es), Various communications protocols such as, for example, CSMA/CD, slotted ALOHA, etc. can be employed by the users in communicating with the associated RBIUs with high efficiency due to the short paths involved relative to the transmission frame durations used on the bus.
