Metropolitan wide area network

Abstract

A wide area communication network includes at least two hub sites which are interconnected by a communication backbone. Each hub site provides wireless coverage in at least one sector. At least two remote sites reside in each sector and are coupled to a corresponding hub site via a point to multi-point broadband wireless system. The network preferably includes at least one service node which is accessible to the remote sites via the hub sites and backbone.

Description

technical field [0001] The present invention relates to metropolitan wide area networks of telecommunication systems. More specifically, the present invention relates to the integration of a wireless point-to-multipoint system operating in the millimeter microwave radio range with an intelligent metropolitan broadband backbone network to enable various enhanced voice, broadband data and multimedia telecommunication services. Background technique [0002] Point-to-point narrowband, point-to-multipoint narrowband and point-to-multipoint broadband fixed wireless systems are generally known in the prior art. Point-to-multipoint radio technology is also known and is typically used for narrowband communications, such as voice communications. A narrowband system is generally a system capable of producing data rates of 1.544 megabits per second or less on a single circuit or channel, while a wideband system is capable of producing data rates greater than 1.544 megabits per second p...

AI Technical Summary

Problems solved by technology

Point-to-point systems cannot efficiently support variable bit-rate or "bursty" data services that require variable bandwidth

Bandwidth used by point-to-point systems for variable bit-rate applications is wasted since each system utilizes the assigned channel on a full-time "always-on" basis, regardless of the amount of information on the link or the duration of the transmission
