Problems solved by technology

But in each case, such a switcher broadcasts the signal in a point-to-multipoint fashion, similar to a cellular solution, and correspondingly less spectrally efficient

Embodiment Construction

[0104] In an arbitrary network with a total of N nodes and E interconnections or links, at each node, the traffic flow into the node minus the traffic flow out of the node must be the net traffic flow generated by the users connected to the node (excluding any buffering). if T ij represents traffic flow from node i to node j, and B i Indicates the user service on node i, then the following equation must hold true at any time:

[0105] For j=0 to N, ∑ i＝0，N T ij =B j ,T ij =-T ji and T jj =0

[0106] (Transport Constraint Equation)

[0107] link traffic T ii As an unknown quantity, and the user traffic is also unknown, there are N+E constraint equations and there are 2E unknowns, where the actual topology of the network indicates the relationship between N and E. There are two classes of network topologies that are of interest for our purposes, those with N≥E and those with N

[0108] The first type of network topology with N≥E means that t...

Abstract

A communications system (1) has a plurality of nodes (2). Each node (2) has a receiver (10) for receiving a signal transmitted by wireless transmitting means and a transmitter (11) for wireless transmission of a signal. Each node (2) further has means for determining if a signal received by said node (2) includes information for another node and causing a signal including said information to be transmitted by said transmitting means to another node if said signal includes information for another node. Each node (2) has a substantially unidirectional point-to-point wireless transmission link (3) to at least one other node. The communications system (1) has high spectral efficiency compared to a broadcast cellular system and allows high data transfer rates to be achieved.

Description

technical field [0001] The present invention relates to a communication system and method. Background technique [0002] There is an increasing demand for broadband communication systems capable of delivering data at rates significantly higher than those available to business or home users. Systems that benefit from high data transfer rates include video-on-demand, videoconferencing and videophone technology, business and home Internet access, local area network (LAN) interconnections, virtual private networks, teleworking, online gaming, high-definition television, and Many other applications requiring high data transfer rates. [0003] In conventional telephone communication systems, the system operator's backbone switching trunk network is connected to an access network which connects the trunk network to subscriber individual telephone sets or private branch exchanges (PBXs). The access network is often referred to as the "local loop". [0004] The vast majority of lo...
