  • Publication number: 20150195055
    Abstract: 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.

  • Publication number: 20150109044
    Abstract: 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).

  • Publication number: 20150031316
    Abstract: 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.

  • Publication number: 20140079077
    Abstract: 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.

  • Publication number: 20140072071
    Abstract: 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.

  • Publication number: 20130295980
    Abstract: 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.

  • Patent number: 8514915
    Abstract: Coverage for a wireless network is improved using a frequency shifting scheme. A wireless signal in a frequency band is shifted to another band, and carried in the shifted band to another location where the signal is shifted back to the original frequency band. The frequency shifting may utilize frequency shifting schemes such as mixer/filter and heterodyne. The wireless signal can be frequency shifted by converting it to other representing signals (such as I/Q components) and forming the frequency-shifted signal from the representations. The transmission medium may use dedicated wiring or existing service wiring in a residence or building, including LAN, telephone, AC power and CATV wiring. The system may be enclosed as a stand-alone unit, housed in integrated form as part of a service outlet or as a snap-on/plug-in module.
