  • Patent number: 6757493
    Abstract: Systems and methods are described for communications links with non-intrusive expansion capability. A first splitter combiner switches form a shut state to a bypass state when a second headend output is communicatively coupled to a first upstream input and a second headed output is communicatively coupled to a first downstream output. The first splitter combiner is then switchable back to the shut state from the bypass state when the either the second headend output is communicatively decoupled from the first upstream input or the second headend input is communicatively decoupled from the first downstream output. The systems and methods provide advantages because a communication network can be equipped for non-intrusive expansion of the network.

  • Patent number: 6618522
    Abstract: Systems and methods are described for communications networks. A method, includes deploying a communication link, at least a portion of which is protected against active equipment failure, that includes a splitter-combiner communicatively coupled between a data drop/add device and a headend. The systems and methods provide advantages because a communication network can be protected, at least in-part, against active equipment (e.g., data drop/add device) failure, passive equipment (e.g., optical fiber) failure, and/or equipped for non-intrusive expansion of the network.

  • Patent number: 6577870
    Abstract: Systems and methods are described for wireless communications. A method includes providing a wireless communications system having narrow cast bi-directional internet channel capability and defining a substantially nonconflicting regional overlay, then transmitting a downstream signal from a downstream transmitter to a bi-directional transceiver; and transmitting an upstream signal from the bi-directional transceiver to an upstream receiver through the substantially nonconflicting regional overlay. The narrow cast bi-directional internet channel capability and the non-conflicting regional overlay define an upstream area that overlies a plurality of smaller downstream areas. The systems and methods provide advantages because additional capacity can be provided within a saturated region without incurring interference and additional capacity can be provided only in the direction in which it is needed.
