  • Patent number: 8896874
    Abstract: A communication apparatus according to one aspect of the present invention determines, in a case where a communication request for communicating with an external apparatus has occurred, whether direct wireless communication between a communication terminal and the communication apparatus with one of the communication terminal and the communication apparatus functioning as an access point is being executed or not. In a case where it is determined that the direct wireless communication is being executed, controls the communication apparatus to not communicate with the external apparatus based on the communication request until a communication method switches from the direct wireless communication to a different communication method, and causes communication with the external apparatus based on the communication request to be executed using the different communication method in response to switching of the communication method.

  • Patent number: 8494370
    Abstract: Embodiments of the invention include systems and method for determining the location of components in a data center. In one embodiment, a component locating system includes a lattice formed of interconnected hubs and rods. Each hub in the lattice computes its address relative to the address of a reference location, such as the location of an adjacent hub or of an origin hub defining the origin of a reference coordinate system. A plurality of optical transmitters is distributed along the lattice to transmit location information. Optical receivers mounted on top of the racks receive the location information and communicate the location information to rack-mounted components. The racks and rack-mounted components determine their locations from the location information and optionally transmit the location information to a central management server.

  • Patent number: 7983649
    Abstract: A RF device such as a tower mounted amplifier (TMA), mast-head amplifier (MHA), or Tower Mounted Boosters (TMB) includes a housing having a plurality of cavities and an input and an output, the input being coupled to the antenna and the output being coupled to a base station. The housing includes a transmission path holding multiple coaxial resonators. The housing further includes multiple receive paths including at least one path having a plurality of cavities, each cavity containing a dielectric resonator. The metallic transmit resonator nearest the antenna input is coupled to the first dielectric resonator via a common resonant wire. The last dielectric resonator in the receive path is coupled to a first metallic resonator of a downstream clean-up filter via another common resonant wire.

  • Patent number: 7933572
    Abstract: A typical cable television (CATV) network can be used as a communication link between a remote antenna system and a cellular base station (BTS). To do so, capacity of the typical CATV network is expanded to add use of an additional frequency spectrum, the added frequency is then divided into frequency channels (bands) of which each channel is digitized (e.g., using QAM) to produce a certain amount data bandwidth per channel, and a certain number of those channels are concatenated together to provide an aggregate data channel for carrying traffic between the cellular BTS and the remote antenna system (e.g., a distributed antenna system (DAS)).

  • Patent number: 7024164
    Abstract: A communication apparatus having a transmission section and a reception section that are selectively attached or detached from one another. The transmission section is operable to modulate an information signal to generate a high frequency signal and to wirelessly transmit the high frequency signal to the reception section, or to output the information signal to the reception section via a non-wireless coupling. The reception section is operable to receive the high frequency signal transmitted from the transmission section and to demodulate the high frequency signal to recover the information signal, or to receive the information signal outputted from the transmission section. Further, an attached condition is sensed, indicating whether the transmission section and the reception section are connected/attached to each other or disconnected/detached from each other, and switching between wireless transmission and non-wireless transmission is performed in accordance with the indicated condition.
