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 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.

Abstract: Systems and methods are described for reverse digitized communications. A method includes: providing at least one optical fiber from at least one member selected from the group consisting of a headend and a hub, a minifibernode coupled to said at least one optical fiber, and an electrical conductor coupled to said minifibernode; transforming a forward optical signal from said at least one optical fiber to a forward analog electrical signal on said electrical conductor at said minifibernode; and transforming a reverse analog electrical signal on said electrical conductor to a reverse digital optical signal at said minifibernode. The systems and methods provide advantages because the need for muxnode units is eliminated, the cost of the node units is reduced, the amount of optical fiber is reduced and the reverse bandwidth is increased.

Abstract: Methods, systems and devices are described relating to a chassis for front and back inserted modules. An apparatus includes a chassis including a first module bay and a second module bay, the first module bay and the second module bay together composing both a forward section and rearward section.

Abstract: Methods, systems and devices are described for a chassis with repositionable plates. An apparatus, including a chassis having a first module bay with a first plate mounting bracket, a second module bay with a second plate mounting bracket and a repositionable plate that is removably connectable to the first plate mounting bracket and removably connectable to said second plate mounting bracket.
