One embodiment is directed to a system that is configured to communicate at least two different types of fronthaul data from a plurality of baseband units to a shared radio point using a single application-layer protocol that supports at least two types of elements. Each of the at least two types of elements is configured for a respective one of the at least two different types of fronthaul data. The system is configured so at least some of the elements communicated using the application-layer protocol include one or more sub-elements, where each sub-element comprises a type field, a length field, and a value portion.
One embodiment is directed to a system to provide wireless service comprising a base band unit and a plurality of antennas communicatively coupled to the base band unit. The system is configured for frequency reuse implemented via the plurality of antennas in order to transmit to subsets of the UEs. The UEs included in each subset are transmitted respectively different data using the same resource elements. The system is configured to collect base station data including Channel Quality Information (CQI) data, Sounding Reference Signal (SRS) data, and hybrid automatic repeat request (HARQ) acknowledgement/negative acknowledgement (ACK/NACK) data for the plurality of UEs. The system is configured to use the base station data to determine candidate UEs for transmission to using frequency reuse and to determine modulation and coding schemes (MCSs) for the UEs transmitted to using frequency reuse.
An enclosure includes a management insert disposed within a housing to divide the interior into three levels. Hybrid cables enter the housing at the first level. Electrical conductors of the hybrid cables are terminated at the second level. Optical fibers of the hybrid cables are terminated at the third level. Excess length of the optical fibers may be stored at the third level. The management insert may be fastened to the housing using plugs received at select ones of the cable entrance/exit locations. A dedicated furcation enclosure is also disclosed.
A light source unit generates an optical signal out of a bend-insensitive (“BI”) optical fiber that is compliant with a desired encircled flux (“EF”). The unit includes a light source to generate an optical light signal and a conventional multimode optical fiber coupled to receive the optical light signal from the light source at a first end. A modal conditioner is arranged to condition the optical light signal propagating along different modes of the conventional multimode fiber. A first bend-insensitive (BI) multimode optical fiber has an input end, the input end of the first BI multimode optical fiber being coupled at a second end of the conventional multimode optical fiber to receive the conditioned optical light signal from the conventional multimode fiber. The output from the first BI multimode optical fiber outputs an optical signal having the desired EF.
The present disclosure relates to a fiber optic cable that includes a plurality of internal optical fibers and a fiber optic cable portion. The fiber optic cable portion includes an outer jacket and an inner conduit, the inner conduit containing the plurality of optical fibers disposed therein. The fiber optic cable further includes a flexible conduit portion, wherein the flexible conduit portion has a proximal end and a distal end. The proximal end is secured to the fiber optic cable portion and the distal end has a terminating device. The terminating device at least partially encases the flexible conduit portion, and the plurality of optical fibers passes through the flexible conduit portion and the terminating device.
Techniques are provided for enhancing accuracy of modelling aggregate interference at each protection point of a geographical area in a region having an urban or suburban morphology type whilst reducing processing requirements by diminishing a number of elevation data that must be obtained from external sources. The geographical area may be a priority access license protection area, a grandfathered wireless protection zone, or other geographic area which must be protected from interference.

The present disclosure describes a power cable connector. The connector includes a main body having a bore therethrough, a first threaded section, and a second threaded section; a back cover having a third threaded section configured engage the first threaded section of the main body; a pair of female conductor pins configured to be coupled to inner conductors of a power cable; an insulator having one or more recesses extending along an outer surface and a fourth threaded section configured to engage with the second threaded section of the main body, the insulator having a pair of inner channels extending therethrough sized to receive the pair of female conductor pins; an end cap including one or more recesses; and a locking nut including one or more protrusions extending radially inward. When the locking nut is inserted onto the insulator and end cap, the one or more recesses of the insulator and one or more recesses of the end cap are configured to receive and guide the one or more protrusions of the locking nut to secure the end cap to the insulator. Connector assemblies are also described herein.
