A method operable by a communication network gateway for providing communication services includes (a) supporting respective communication links with a plurality of communication service providers, (b) supporting a plurality of virtual local area networks (VLANs), (c) associating each virtual local area network (VLAN) with a respective communication service provider of the plurality of communication service providers, and (d) routing data between each VLAN and the respective communication link of the respective communication service provider associated with the VLAN.

Communication network gateways and associated methods

The present disclosure generally relates to apparatus, software and methods for thwarting radio spoofing techniques by requiring and sending data from multiple radios positioned such that the receiving client can determine that it came from multiple spatially separated radios due to the Angle of Arrival of each radio's signal.

Using multiple radio streams to thwart man-in-the-middle attacks

A mesh wireless access point (WAP) includes a housing, a first radio assembly, a second radio assembly, and an internal communication link between the first and second radio assemblies. The housing is configured to be affixed to, or integrated with, a feature of a building. The first radio assembly is incorporated with the housing and configured to support a first wireless communication link, and the second radio assembly is incorporated with the housing and configured to support a second wireless communication link. The internal communication link is configured to transfer data packets between the first and second radio assemblies.

Mesh wireless access points

A coherent optical injection locking (COIL) apparatus generates multiple optical source outputs from a single optical source generated by a parent laser. The COIL apparatus includes a plurality of optical source generators each having a child laser, of lesser performance than the parent laser, that is injection locked to the single optical source. The optical source generators may have one or both of a shared configuration and a cascaded configuration that replicates the single optical source, or a single wavelength of the single optical source when it is a comb source.

Methods of injection locking for multiple optical source generation

A method for transmitting data through a multi-media communication network includes converting transmission entities into data symbols at a first communication device, transmitting the data symbols from the first communication device to a second communication device through at least two different types of communication media using only lower PHY layers of the at least two different types of communication media, and converting the data symbols into transmission entities at the second communication device. A network implementing a universal data link includes a first communication device configured to convert transmission entities into data symbols, a second communication device configured to convert the data symbols into transmission entities, at least a first communication medium and a second communication medium communicatively coupled between the first communication device and the second communication device, and a first physical-layer translator configured to translate data symbols without converting the data symbols into transmission entities.

Systems and methods for a universal data link

A method of securing data transmission from a plurality of spatially distributed transmitters to a receiving device includes steps of: determining first and second receiving device propagation delays for first and second transmission paths, respectively; portioning a contiguous stream of data into first and second data portions; transmitting the first data portion by the first transmission path utilizing a coordinating system and first propagation delay, and the second data portion such that first and second data portions arrive at the receiving device during a first and second time period, respectively, wherein, when seen from the receiving device, the first data portion and second data portion are seen as transmitted as contiguous data from the same transmitter, and wherein that transmitted data is received as a contiguous stream of transmitted data at a location of the receiving device.

Systems and methods for coordinated security enhancement

Mitigation of satellite interference is contemplated. The mitigation may include processing satellite transmissions to remove interferences based on an amount of signal overlap, such as to facilitate mitigating interferences resulting from satellite spacing and/or ground antenna dish size.

Mitigating satellite interference

A local communication network (LCN) is contemplated. The LCN may be established within an existing network by leveraging network capabilities in order to facilitate local communications of the type whereby point-to-point (P-to-P) or other types of messaging and/or signaling may be communicated directly between devices without having to be relayed through a headend, a termination system or other processing entity.

Local communications network

A method for transmitting data through a multi-media communication network includes converting transmission entities into data symbols at a first communication device, transmitting the data symbols from the first communication device to a second communication device through at least two different types of communication media using only lower PHY layers of the at least two different types of communication media, and converting the data symbols into transmission entities at the second communication device. A network implementing a universal data link includes a first communication device configured to convert transmission entities into data symbols, a second communication device configured to convert the data symbols into transmission entities, at least a first communication medium and a second communication medium communicatively coupled between the first communication device and the second communication device, and a first physical-layer translator configured to translate data symbols without converting the data symbols into transmission entities. In order to reduce processing time and end-to-end latency, the physical-layer translator only performs demodulation and modulation operations, optionally also equalization.
