Abstract: Certain aspects and aspects of the present invention are directed to a distributed antenna system having a downlink communication path, an uplink communication path, and a non-duplexer isolator sub-system. The downlink communication path can communicatively couple a transmit antenna to a base station. The uplink communication path can communicatively couple a receive antenna to the base station. In one aspect, the non-duplexer isolator sub-system can be electronically configured for isolating uplink signals traversing the uplink communication path from downlink signals. In another aspect, a non-duplexer isolator sub-system can be configurable in one or more mechanical steps selecting a frequency response.

Abstract: A mobile communication system includes: a first antenna for receiving communication signals; processing circuitry for processing received communication signals; a second antenna for transmitting processed signals. The processing circuitry utilizes at least one configurable setting for processing received communication signals, the configurable setting being adaptable for varying the processing of received communication signals as the system moves through a mobile environment. The processing circuitry configured to: receive, over time, input representing current geographical location of the system; determine whether the system is entering a first geographical zone based on the input representing the current geographical location and path of system; and automatically adapt the configurable setting as the system enters the first geographical zone, wherein adaptation of configurable setting is based on known signal characteristics associated with the received signals from mobile devices in the first geographical zone.

Abstract: A telecommunications system is provided that includes a unit for communicating channelized digital baseband signals with remotely located units. The channelized digital baseband signals include call information for wireless communication. The unit includes a channelizer section and a transport section. The channelizer section can extract, per channel, the channelized digital baseband signals using channel filters and digital down-converters. The transport section can format the channelized digital baseband signals for transport together using a transport schedule unit for packetizing and packet scheduling the channelized digital baseband signals. A signal processing subsystem can control a gain of uplink digital baseband signals, independently, that are received from the remotely located units prior to summing the uplink digital baseband signals.

Abstract: Certain aspects involve a wideband remote unit. The wideband remote unit can include one or more antennas and an analog-to-digital converter (“ADC”). The antenna can receive wideband signals. The wideband signals can include an uplink RF signal and a leaked downlink RF signal. The uplink RF signal can have an uplink signal power at or near a noise level. The leaked downlink RF signal can have a downlink signal power greater than the uplink signal power. The ADC can convert the received wideband signals to digital RF signals representing the uplink signal and the downlink signal. The wideband remote unit can transmit the digital RF signals to a unit of a DAS that is in communication with a base station.

Abstract: Certain aspects are directed to a base station router disposed in a distributed antenna system. The base station router includes a backplane and a controller. The backplane can manage an availability of sectors for coverage zones. Each sector can include communication channels to be radiated to mobile devices in the coverage zones and can represent an amount of telecommunication capacity. The controller can respond to a traffic indicator by causing the backplane to redistribute the availability of at least one sector. The sector can be redistributed from a first coverage zone to a second coverage zone.
