摘要： 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.

摘要： In a printed circuit board having stacked units, a protruding portion of a first of the units can extend across and past at least one of the peripheral edges of a non-conductive substrate of a second of the units. The protruding portion of the first unit may include at least a portion of a conductor of the first unit, and the portion of the conductor of the first unit may be configured for being connected to an electronic device. 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.

摘要： 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.

摘要： 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.
