20160080085 | EXTREMELY HIGH FREQUENCY (EHF) DISTRIBUTED ANTENNA SYSTEMS, AND RELATED COMPONENTS AND METHODS - Extremely High Frequency (EHF) distributed antenna systems and related components and methods are disclosed. In one embodiment, a base unit for distributing EHF modulated data signals to a RAU(s) is provided. The base unit includes a downlink data source input configured to receive downlink electrical data signal(s) from a data source. The base unit also includes an E-O converter configured to convert downlink electrical data signal(s) into downlink optical data signal(s). The base unit also includes an oscillator configured to generate an electrical carrier signal at a center frequency in the EHF band. The base unit also includes a modulator configured to combine the downlink optical data signal(s) with the electrical carrier signal to form downlink modulated optical signal(s) comprising a downlink optical data signal(s) modulated at the center frequency of the electrical carrier signal. The modulator is further configured to send the downlink modulated optical signal to the RAU(s). | 2016-03-17 |
20160080086 | MULTI-LINK MOBILE COMMUNICATIONS - Systems and methods presented herein provide for improved access to data. In one embodiment, a communication system includes an RF communication link that is operable to receive first communications from a mobile device (e.g., a cell phone, tablet computer, laptop computer, or other “user equipment”). The communication system also includes a processor operable to determine a location of the mobile device based on the first communications and a plurality of directional communication links. Each directional communication link is operable to transfer data to the mobile device based on the location of the mobile device as determined by the processor. The processor is also operable to coordinate the transfer of data from each of the directional communication links to the mobile device. | 2016-03-17 |
