摘要： A method for allocating resources in a wireless network includes establishing one or more links. The method also includes the following iterative steps: allocating a first number of slots to the relay links; dividing the first number of slots among the relay links; determining a representative relay data rate indicative of a data rate provided by one of the relay links for one of the multi-hop access links; allocating the second number of slots to the multi-hop access links; dividing the second number of slots among the multi-hop access links; determining the effective multi-hop data rate based on the minimum of the representative relay link data rate and the multi-hop data rate; allocating the third number of slots to the single-hop access links; dividing the third number of slots among the single-hop access links; and upon the single-hop data rate being approximately equal to the effective multi-hop data rate, provisioning the first, second and third number of slots.

摘要： A method for balancing network load includes determining an initial capacity of a wireless network comprising a plurality of endpoints coupled to a plurality of different types of access stations. The access stations comprise one or more relay stations and at least one base station. The method also includes identifying one or more endpoints that would increase capacity of the wireless network if switched to a different access station. The method further comprises tentatively switching the identified endpoints from their current access station to a different access station. The method additionally includes determining if the capacity of the wireless network is increased from the initial capacity by the tentative switch and, upon the capacity of the wireless network increasing, switching the identified endpoints from their current access station to a different access station.

摘要： A method for selecting an access link in a multi-hop relay network includes determining a first effective spectrum efficiency value of a first connection between an endpoint and a base station. The first effective spectrum efficiency value is indicative of the spectrum efficiency from the endpoint to the base station when the first connection is used. The method also includes determining a second effective spectrum efficiency value of a second connection between the endpoint and the base station via a relay station. The second effective spectrum efficiency value is indicative of the spectrum efficiency from the endpoint to the base station when the second connection is used. The method also includes comparing the first and second effective spectrum efficiency values. The method further includes establishing a connection using one of the first or second connections based on the comparison of the first and second effective spectrum efficiency values.

摘要： In a method for manufacturing multilayer PCBs having n circuit layers, a flexible substrate strip is provided. The strip comprises a number of PCB units, each comprising n segmental portions. The strip is treated in a reel to reel process to form traces in n−2 segmental portions of each of the PCB units, the other two segmental portions are left untreated without traces. Then the strip is cut to obtain a number of separated PCB units. The PCB unit is folded in such a manner that the n−2 segmental portions having traces are arranged between the other two segmental portions without traces. The folded PCB unit is laminated to form a multilayer substrate and traces are formed in the two segmental portions.

摘要： In a method for manufacturing multilayer PCBs having n circuit layers, a double-sided flexible substrate strip is provided. The strip comprises a number of PCB units, each comprising m segments, wherein m=n/2 if n represents an even integer, and m=(n+1)/2 if n represents an odd integer. Each segment includes two foil portions. In a reel to reel process, the strip is treated to form n−2 foil portions of each PCB unit into traces, further remove one foil portion if n represents an odd integer. The other two foil portions are left untreated. Then the strip is cut to separate the PCB units from each other. The PCB unit is folded in such a manner that the traces are arranged between the other two foil portions. The folded PCB unit is laminated to form a multilayer substrate and traces are formed in the two foil portions.
