2901 results about "Coaxial cable" patented technology

Coaxial cable, or coax (pronounced /ˈkoʊ.æks/) is a type of electrical cable that has an inner conductor surrounded by a tubular insulating layer, surrounded by a tubular conducting shield. Many coaxial cables also have an insulating outer sheath or jacket. The term coaxial comes from the inner conductor and the outer shield sharing a geometric axis. Coaxial cable was invented by English physicist, engineer, and mathematician Oliver Heaviside, who patented the design in 1880.

System and method for optimizing network capacity in a cellular wireless network

A system and method is disclosed for increasing the efficiency of a cellular communication network, reduce ongoing operating costs and increase revenue. According to one aspect, a method is disclosed for increasing the efficiency of a cellular communication network whereby network capacity in the radio access network (RAN) and baseband processing for wireless connections are dynamically adjusted to automatically provision sufficient bandwidth and baseband processing capacity in response to changes in the network. The method is further extended by implementing policy management which allows wireless carriers to develop and implement network based policies to automatically increase or decrease the amount of processing resources and network bandwidth required from any cell site, hub or mobile switching office. According to another aspect, network efficiency is enhanced by utilizing a novel cellular network infrastructure. RF signals from cell site antennas of various technology types are demodulated, digital bit information is extracted from the RF signals, processed, and groomed into Gigabit Ethernet/Resilient Packet Ring (GigE/RPR) or Ethernet over copper traffic flows using specific Quality of Service (QoS) priorities. The GigE/RPR traffic flows are routed to hub sites or mobile switching offices, at which point the packetized information is extracted and converted to RF signals that are equivalent to the signals that were received at the antenna. The RF signals are sent over coaxial cable to a network hub including a pool of Base Transceiver Stations (BTSs) (or Node Bs). The hub is coupled to one or more mobile switching offices via a second fiber optic ring.

Broadband access transmission network integrating the functions of electric power network, telecommunication network, tv network and internet

A broadband access transmission network integrating the functions of electric power network, communication network, TV network and Internet relates to network transmission. It includes a broadband transmission network of 10 KV power distribution network and a broadband transmission network of low-voltage power distribution network. These two transmission networks are connected via distribution transformers and optical fiber connectors. The broadband transmission network of 10 KV power distribution network is composed of optical compound power lines, wires, transformer substations, machine rooms, taps, insulating jackets, insulating waterproofing outer jackets and optical fiber connectors. The broadband transmission network of low-voltage power distribution network is composed of optical compound power lines, coaxial cable compound power lines, taps, insulating jackets, optical access points, distributors, modems and two-way amplifiers. The invention can perform high-speed broadband communication and power transmission on the same compound wires. It utilizes the existing power network sufficiently and prevents the cost of rebuilding the communication network, cable TV network and Internet, and can simultaneously perform building, operating, maintaining and managing of these networks.

System and method for distributing information via a communication network

A communication system for distributing information via a network to one or more subscribers includes a multi-port switch, one or more radio frequency (RF) modems coupled to respective ports of the switch, a combiner and a transmitter. The switch forwards source information to the RF modems based on address information. Each RF modem modulates and up converts information from the switch to an RF signal within a respective subscriber channel of the television broadcast spectrum. Each channel is assigned to one or more subscribers, and each subscriber is allocated unshared bandwidth. Each channel may be further divided into unshared bandwidth increments, so that multiple subscribers may share a single channel. The combiner combines modulated information from each RF modem into a combined signal and the transmitter transmits the combined signal to the subscribers via the network. An HFC network including a distribution point and one or more optical nodes is contemplated, each optical node serving a particular geographic area via a corresponding coaxial cable. Each subscriber destination includes a gateway device or the like that is tuned to a corresponding channel to retrieve source information from that channel, and to deliver the information to one or more local subscriber devices. The gateway further includes converters, a modulator and an up converter to receive and transmit subscriber information upstream to the distribution point. The gateways and an address resolution server enforce point to point communications. A bandwidth manager allocates bandwidth and monitors bandwidth usage.

Coaxial cable connector with replaceable compression ring

A male compression-type coaxial cable connector having an adapter nut attached to a leading end of a tubular connector body portion. The connector body portion has a first axial conduit with a barbed ferrule coaxially mounted therein. The connector further comprises a compression sleeve having a second axial conduit slidingly disposed over a trailing end of the tubular connector body portion. A deformable compression ring is removably disposed within the second axial conduit. In use, the prepared end of the coaxial cable is inserted through the compression sleeve and compression ring and advanced into the connector body conduit until it can be advanced no further. Subsequent advancement of the compression sleeve over the connector body portion, with the assistance of a compression tool, forces the deformable trailing end of the compression ring radially inward to compress the cable jacket and braid thereby providing secure attachment of the connector to the cable. The compression ring is removable and can be replaced with another compression ring having a different inner diameter to accommodate a variety of coaxial cables. The construction permits the compression sleeve to be easily removed for replacing the compression ring and easily reinstalled over the connector body after ring replacement.

Sealed coaxial cable connector and related method

A connector is provided for coupling an end of a coaxial cable to a terminal, such as a cable terminal, a terminal for coupling to another connector, and the like. The connector includes a coupler, such as a nut, having a receiving port for engaging the terminal. The coupler also includes an annular collar. The connector also includes a body member, one end of which includes a lip. The lip is inserted through the collar opening. The other end of the body section includes an inner surface portion. The connector still further includes a post, an end of which is sized for insertion between the dielectric and the outer conductor of the cable. The post further includes a post flange and a post shank. The post shank forms a post channel sufficient in diameter to receive the inner conductor and the dielectric of the cable. The post is movable between a cable-insertion position and a cable-installed position. In the cable-installed position, the post shank is received in the body member to form an annular chamber between the post shank and the inner surface portion. The annular chamber is sufficiently narrow in this cable-installed position to compress the outer conductor and the jacket with the post shank and the inner surface portion for establishing a distal seal. Tightening of the coupler to the terminal compresses the lip between the post flange and the annular collar for establishing a proximal seal. Related methods also are provided.
