  • Publication number: 20140266943
    Abstract: A polarization adjustment assembly for a reflector antenna is provided with a radio bracket with a mounting flange. The mounting flange is coupled to a hub provided with a stop portion. Fasteners couple the radio bracket to the hub via slots in the mounting flange, rotatable with respect to the hub within the extents of the slots. An adjustment bolt passes through a boss coupled to the mounting flange. The adjustment bolt abuts the stop portion, whereby longitudinal displacement of the adjustment bolt with respect to the boss rotates the radio bracket with respect to the hub. Alternatively, the positions of the boss and stop portion on the mounting flange and hub may be exchanged.

  • Publication number: 20140269966
    Abstract: A method and apparatus for determining placement of a plurality of antennas of a distributed antenna system for handling MIMO signals includes, at a first location, simulating the communication of a first MIMO signal by a first remote unit over an air interface in an environment and, at a second location, simulating the communication of a second MIMO signal by a second remote unit over an air interface in the environment. The first and second locations are arranged within the environment to provide overlapping signal coverage of both the first MIMO signal and the second MIMO signal at a third location in the environment. Analysis is made of at least an imbalance of received power between the first and second MIMO signals within the environment at a third location in order to determine whether a desired capacity for MIMO communications with the system has been achieved at the third location.
