Abstract: A communication device includes statistical analysis module and interference mitigation circuitry. In some embodiments, statistical analysis module is configured to receive a set of standards-based channel information (SCI), such as a set of beamforming reports taken for a set of spatial streams, or a set of subscriber unit air quality information. The received SCI correspond to subscriber unit(s) in communication with a base station and operate at radio frequencies such as millimeter waves above 30 GHz. The statistical analysis module is configured to determine, from the received SCI, if communication between the base station and subscriber unit(s) is affected by interference, and determining the source and location of communication interference.

Abstract: Scheduling and allocating resources in a millimeter wave communication system are performed by components of both the MAC and the RF front end acting in cooperation with one another. MAC components operate essential in accordance with the 802.11 standard. Signals at 2.4/5 GHz intermediate frequency (IF) output from an IF module are upconverted to an RF mmWave spectrum. The RF signals are routed to different subsector antennas and/or polarizations of a subsector antenna in order to direct the RF mmWave signal to a desired destination. Beamforming by the physical structures of antennas, direct the RF signals to a particular subsector. The combination of allocating resources within the MAC, processing within the MBI module before being upconverting to RF, together with signal switching of the RF signals, determines the destination to which signals are to be transmitted and the source from which signals are to be received.

Abstract: An office communication system for enabling electronic forms to be provided to a potential customer/client (PCC). In some cases, the form is sent from an office system to a PCC device.

The information on the form can then in some instances be distributed to remote devices that store the information until requested.

Abstract: Systems and methods for providing user information to an enterprise network of a business or service facility. A user device provides information in a form in response to coming in proximity to a participating enterprise network.

In other cases, the user device already has the desired form and merely responds to the request from the enterprise network for the completed form. Information provided in the form can be stored in the user device or in an external storage, such as in a cloud system or other external storage system.
