Residential communications gateway (RCG) for broadband communications over a plurality of standard POTS lines, with dynamic allocation of said bandwidth, that requires no additional equipment or modifications to the associated class 5 offices or the PSTN at large
ActiveUS20050078690A1Easy to deployEliminates tremendously expensive infrastructure costInterconnection arrangementsNetwork traffic/resource managementResidenceEngineering
The Residential Communications Gateway (RCG) is a broadband communications device that combines all voice, data and video communications to and from a typical residence or small business for transmission over a single, or a plurality of Plain Old Telephone Service (POTS) lines separately or in conjunction with, a wireless broadband backbone. The RCG does this by employing packetized data with Voice over Internet Protocol (VoIP) technologies combined with RF communications technologies. A key consideration to the design of the RCG is that no additional or special transmission equipment must be installed at the Central Office or anywhere else in the network to enable new calling features provided by the RCG as is the case with DSL and Cable systems. By eliminating the requirement for costly infrastructure enhancements, ubiquitous high speed communications and services can be deployed to every POTS subscriber.

Multiple input multiple output (MIMO) wireless communications system
ActiveUS7333455B1Minimize waterMinimize ground bounce nullPower managementModulated-carrier systemsPolarization diversityFrequency spectrum
A wireless broadband communications system that can transmit signals over communications links with multiple modes of diversity, thereby allowing signals having very low correlation to propagate over the link along multiple orthogonal paths. The system can be implemented as a non-line-of-sight (NLOS) system or a line-of-sight (LOS) system. The NLOS system employs orthogonal frequency division modulation (OFDM) waveforms to reduce multi-path interference and frequency selective fading, adaptive modulation to assure high data rates in the presence of channel variability, and spectrum management to achieve increased data throughput and link availability. The LOS system employs space-time coding and spatial and polarization diversity to minimize ground bounce nulls. The system achieves levels of link availability, data throughput, and system performance that have heretofore been unattainable in wireless broadband communications systems.

A wireless broadband communications system that can maintain high data rates while taking into account channel interference resulting from operating in shared frequency bands, signal fading resulting from dynamic channel degradation, and signal distortion resulting from compliance with maximum power output regulations. In one mode of operation, the system performs adaptive modulation by transmitting a first signal over a selected channel using a first modulation mode having a level of distortion associated therewith resulting from operating the system at a predetermined maximum power output level. Next, a SINAD level is measured on the first channel. The level of distortion associated with the first modulation mode is then subtracted from the measured SINAD level to obtain a first noise level. In the event the first noise level is less than a noise level required to achieve an acceptable error rate in a next modulation mode, a second signal is transmitted over the selected channel using the next modulation mode.

A wireless broadband communications system and method that achieves reduced latency for high priority data when multiplexed with lower priority data for transmission over a TDD point-to-point radio link. The system prepares multiple data streams for transmission over a TDD radio link by buffering multiple data streams containing high and low priority packets in separate queues based upon their corresponding priority level. Each packet in the higher priority queues has a specified size, and a header defining the type of service provided and the packet destination. Next, the packets in the lower priority queues are fragmented to a reduced size based upon the data capacity of the link. The high priority packets and the fragmented, low priority packets are arranged in a sequence such that the high priority packets are transmitted first, and the low priority packets are transmitted when no data is buffered in any high priority queue.

A system and method for fast acquisition of a communication link in a wireless broadband communication system between a mobile station and a base station includes a scheduler (100) that is informed (102) of the processing capabilities of the mobile station, preferably in an optional message field.

The scheduler allocates (106) uplink bandwidth for the mobile station to respond to the downlink message at the determined time. In this way, upon sending (108) a message from the base station to the mobile station, the mobile station can immediately respond (112) at the allocated time without having to perform an explicit bandwidth request.

The present disclosure relates to an early warning and recommendation system for proactive management of a wireless broadband network. Without human intervention, the system processes highly heterogeneous network and non-network data and applies unsupervised machine learning to the data to predict and understand the situations that lead to different network state conditions. More specifically, unsupervised clustering is applied to the data to understand “situations” that can lead to non-normal network state conditions. A deep neural network model of situations is then created to further understand the underlying data relationships between the elements of a situation and network states. The deep neural network model and Reinforcement Learning is used to provide recommendations as to changes in wireless / mobile broadband network configuration parameters that will improve the state of a predicted situation associated with non-normal network conditions. The system displays warnings and corresponding recommendations regarding predicted non-normal network conditions in a user interface for a network operator.
