  • Patent number: 7173183
    Abstract: Three specific problems or needs related to deployment of fiber optic repeater distributed antenna systems are addressed by providing a particularly configured enclosure or cabinet adapted to protect repeaters from vandalism, enclose power components directly below the repeaters, and provide uninhibited ventilation. The cabinet includes a first cabinet portion partially enclosing a first chamber in which the repeater is receivable, a second cabinet portion at least partially enclosing a second chamber in which the power source components are receivable, and a door mounted to the first cabinet portion so as to be movable between a closed position, in which access to the first chamber is prevented, and an open position, providing access to the first chamber. A locking mechanism by which the door can be securely retained in the closed position includes a handle which is redundantly securable in an inoperative position, thereby preventing locking mechanism operation and precluding access to the first chamber.

  • Publication number: 20070026864
    Abstract: A system and method for reducing power consumption and interference in a communications system that has multiple base radios. A base radio controller assigns priorities to the base radios in the system. When higher priority base radios have excess capacity, intracell handovers are used to consolidate communications from lower priority base radios to higher priority base radios. After transferring communications to higher priority base radios, the lower priority base radios can attenuate or shut off their transmitted signal in order to reduce or eliminate all the interference they cause other base stations in the system, and reduce transmission power requirements.

  • Patent number: 7149198
    Abstract: A wireless communication system including an originator media gateway to encode voice data into an IP packet depending on whether tandem free operation (TFO) or normal operation is being used. The media gateway makes such determination independent of the TFO protocol being used. In particular, the media gateway determines that TFO is being used by determining whether bits in particular fields of a predetermined number N of voice octets are filler bits or not. If they are filler bits, then TFO is being used, otherwise, normal operation is being used. If TFO is being used, the media gateway forms an IP packet with data from only another particular fields of the voice octets. If normal operation is used, the media gateway forms an IP packet with data from the entire voice octets. A target media gateway determines TFO or normal operation by examining the size of the received IP packet.

  • Publication number: 20060256812
    Abstract: Systems and methods for obtaining location information for a communication station in a first domain by a communication station in a second domain are provided. The communication station in the second domain embeds a location request message in a message formatted according to a first communication protocol, and transmits the message formatted according to the first communication protocol to a proxy server. The proxy server removes the embedded request message and forwards it to a location server, which is located in the first domain. The proxy server receives a location response message and embeds it in another message formatted according to the first communication protocol. The proxy server then transmits the another message formatted according to the first communication protocol to the communication station in the second domain, which can remove the embedded location response message.
