20150195055 | SEPARATION OF COMMUNICATION SIGNAL SUB-BANDS IN DISTRIBUTED ANTENNA SYSTEMS (DASS) TO REDUCE INTERFERENCE - Separation of sub-bands of communications signals to reduce interference in distributed antenna systems (DASs) is disclosed. A sub-band separation circuit coupled to a plurality of antennas is configured to distribute and receive and transmit a pair of downlink and uplink sub-band signals. The sub-band separation circuit is coupled to a duplexed port of a remote unit that distributes uplink communications signals to the DAS and receives downlink communications signals from the DAS. In order to isolate the downlink communications signals from the uplink communications path in the remote unit, the isolation circuit includes a plurality of sub-band isolation circuits. Each sub-band isolation circuit is configured to isolate at least one sub-band of the downlink communications signal to generate a downlink sub-band signal that has a desired frequency separation or gap with uplink communication signals received at the duplexed port. | 07-09-2015 |

The electronic device may include conductive leads or legs protruding from a body of the electronic device so that a gap is defined between the legs, and the protruding portion of the first unit may be positioned in the gap. Circuit board conductors on opposite sides of the protruding portion may be respectively connected to the legs, such as by soldering. | 06-11-2015 |
20150109044 | VARIABLE AMPLITUDE SIGNAL GENERATORS FOR GENERATING A SINUSOIDAL SIGNAL HAVING LIMITED DIRECT CURRENT (DC) OFFSET VARIATION, AND RELATED DEVICES, SYSTEMS, AND METHODS - Embodiments disclosed include variable amplitude signal generators for generating a sinusoidal signal having limited direct current (DC) offset variation and related devices and methods. Instead of employing a single pulse width modulation (PWM) signal to generate a sinusoidal signal, in one embodiment, a circuit is provided that generates two PWM signals. The first PWM signal is a high-to-low PWM signal, where the active state is a lower signal level. The second PWM signal is a low-to-high PWM signal where active state is a higher signal level. The first and second PWM signals are combined to provide a summed signal, which is filtered to generate a sinusoidal signal. The DC offset of the first PWM signal varies inversely to the DC offset of the second PWM signal. In this manner, distortions caused by variations in the DC offset present in the generated sinusoidal signal are limited (i.e., reduced or eliminated). | 04-23-2015 |
20150031316 | MONITORING NON-SUPPORTED WIRELESS SPECTRUM WITHIN COVERAGE AREAS OF DISTRIBUTED ANTENNA SYSTEMS (DASs) - Monitoring non-supported wireless spectrum within a coverage area of a distributed antenna system (DAS) in which a listening module connected to a remote unit of the DAS monitors non-supported wireless frequencies (i.e., frequencies that are outside the frequency ranges supported by the downlink and uplink signals of the DAS), via one or more antennas. The listening module also transmits the wireless frequencies to a monitoring module connected to head end equipment (HEE) of the DAS. In that manner, a monitoring module can use an existing DAS infrastructure to monitor non-supported portions of the wireless spectrum at remote locations. In addition to avoiding the need to run a parallel DAS infrastructure, the disclosed arrangements are also useful in shared spectrum environments and other environments where efficient spectrum utilization is desired. | 01-29-2015 |

The system includes a mobile reader and a memory. The mobile reader is configured to read a unique identification of an equipment unit and to determine a location of the equipment unit while proximate the equipment unit. The location and the unique identification of the equipment unit is associated and stored in the memory. The memory may be located in the mobile reader or in a remotely located database. The mobile reader may be an optical reader configured to read the unique identification from an optical barcode associated with the equipment unit, or the mobile reader may be an RFID reader configured to read the unique identification from an RFID tag associated with the equipment unit. | 06-26-2014 |

20140119735 | DEPLOYABLE WIRELESS INFRASTRUCTURES AND METHODS OF DEPLOYING WIRELESS INFRASTRUCTURES - Wireless infrastructures have hardware and cable components capable of mobile, rapid deployment and recovery. The wireless infrastructures can be transported to a deployment site and remote units deployed to individual coverage areas. A communications path is established between head end equipment and the remote units to provide wireless communications to the coverage areas. When the deployment has ended, the infrastructure can be recovered and transported from the deployment site for use at another deployment. | 05-01-2014 |
20140079077 | COMMUNICATION SYSTEM USING LOW BANDWIDTH WIRES - A high frequency signal is down-converted into an intermediate frequency signal, transmitted over a limited bandwidth medium from a master unit to a remote unit and up-converted back into its original high frequency at the remote unit. The up-conversion is aided by reconstruction of a reference signal embedded at the master unit as a carrier for a management signal which is transmitted to the remote unit through the same limited bandwidth medium together with the intermediate frequency signal. The reference signal is reconstructed using a phase locked loop which includes a charge pump and is kept stable during intervals between bits and messages by a charge pump shutter. | 03-20-2014 |
20140072071 | DISTRIBUTED ANTENNA SYSTEM FOR MIMO TECHNOLOGIES - A method and system for supporting MIMO technologies which can require the transport of multiple spatial streams on a traditional Distributed Antenna System (DAS). According to the invention, at one end of the DAS, each spatial stream is shifted in frequency to a pre-assigned band (such as a band at a frequency lower than the native frequency) that does not overlap the band assigned to other spatial streams (or the band of any other services being carried by the DAS). Each of the spatial streams can be combined and transmitted as a combined signal over a common coaxial cable. At the other “end” of the DAS, the different streams are shifted back to their original (overlapping) frequencies but retain their individual “identities” by being radiated through physically separate antenna elements. | 03-13-2014 |

20130329825 | METHOD AND SYSTEM FOR IMPROVING UPLINK PERFORMANCE - Distributed antenna systems and more particularly to methods and systems for improving uplink communications are disclosed. In one embodiment, Aggregation Point Noise Blocking provides for blocking or filtering of the noise contributed by one or more of the branches coupled to an aggregation point that are not carrying the signal from a particular terminal. Signal activity from a given terminal on a particular branch can be identified and that information can be used to selectively block or filter the signal noise contributed by the other branches to an aggregation point. The selective blocking or filtering can also include an attenuation function to attenuate the signal and provide dynamic range smoothing. | 12-12-2013 |
20130295980 | DETERMINING NOISE LEVELS IN FREQUENCY BAND(S) IN DISTRIBUTED ANTENNA SYSTEMS AND ADJUSTING FREQUENCY BAND(S) OF COMMUNICATIONS SIGNALS IN RESPONSE, AND RELATED COMPONENTS, SYSTEMS, AND METHODS - Determining noise levels in frequency band(s) for communications paths in distributed antenna systems. Noise may be induced in communications paths in distributed antenna system as a result of electromagnetic interference from communications media located in close proximity and/or from other electronic devices. Noise induced on communications media may not be evenly distributed across the frequency spectrum, but instead concentrated in certain portions of the frequency spectrum. The frequency band(s) of communication signals distributed in the distributed antenna systems may be adjusted to be provided outside of frequency band(s) having unacceptable noise levels. In this manner, the communications performance (e.g., the signal-to-noise (S/N) ratio) of communications signals communicated in the distributed antenna systems may be improved. | 11-07-2013 |
