摘要： Certain aspects are directed to a capacity optimization sub-system for a distributed antenna system. The capacity optimization sub-system includes a switch matrix and a controller. The switch matrix includes variable attenuators and switches. The switch matrix can receive sectors from base stations. The switch matrix can provide the sectors to coverage zones. The controller can communicate with the switch matrix. The controller can determine that a number of wireless devices in one or more of the coverage zones is outside a specified range of threshold traffic levels. In response to determining that the number of wireless devices is outside the specified range of threshold traffic levels, the controller can configure one or more of the variable attenuators and corresponding switches to redistribute capacity among the coverage zones by, for example, increasing and/or decreasing capacity in one or more of the coverage zones.

摘要： Aspects and features are directed to an uplink integrity detection sub-system. In one aspect, a distributed antenna system is provided that includes a remote antenna unit that communicates with wireless devices in a coverage area, additional remote antenna units that communicate with wireless devices in additional coverage areas, and a unit that communicates with the remote antenna unit and the additional remote antenna units. The unit includes a distributed antenna system controller. The distributed antenna system controller can determine that an undesirable signal component having a power level exceeding a threshold power is communicated via an uplink path from the remote antenna unit. The distributed antenna system controller can also minimize an impact of the undesirable signal component on the additional coverage areas of the additional remote antenna units. Minimizing the impact can include modifying the gain of the uplink path over which the undesirable signal component is communicated.

摘要： A distributed antenna system includes a master unit (502) configured to receive at least one set of multiple input multiple output (MIMO) channel signals from at least one signal source (490). The master unit (502) is configured to frequency convert at least one of the MIMO channel signals L1, L2 to a different frequency from an original frequency, and combine the MIMO channel signals L1, L2 for transmission. An optical link (602) couples the master unit (502) with a remote (506) for transceiving the MIMO channel signals. The remote unit (506) is configured to receive the MIMO channel signals L1, L2 to be transmitted over antennas (648, 650) and includes an extension port (628) configured to transceive at least one of the MIMO channel signals L1, L2. An extension unit (510) is coupled to the remote unit (506) and is configured to frequency convert at least one of the first and second MIMO channel signals L1, L2 from the different frequency back to an original frequency for transmission over an antenna (650).
