Abstract: A method for installing software to software-defined radio equipment. The method includes the step of transferring software to one or more software-defined radio devices from a remotely located software server. The software server can be a computer operatively connected to the software-defined radio device via a communications network. The transferring step can occur while the software-defined radio device continues to perform software-defined radio functions. The software can be stored to a portion of a data store associated with the software-defined radio device which is not being used as a storage for currently running software. The software can be loaded on a restart of the software defined device. An error indication can be provided if a fault occurs in the transferring step or the loading step. The method also can include the step of reverting from the selected software to a previous software version upon a fault occurrence.

Abstract: A method of frequency hopping is supported by a basestation having a broadband transceiver. The method permits changing physical channels upon which mobile subscribers communicate with the basestation, wherein the broadband transceiver is operated using static transceiver frequencies, the method exclusive of switching communication signals between transceivers. In one embodiment, the method maps baseband output signals from a digital channelizer which represent physical channels to ones of digital signal processors representing logical channels and baseband input signals of a digital combiner to ones of logical outputs of digital signal processors according to a mapping signal.

Abstract: The invention discloses a method and apparatus for diagnosing a backhaul communications link between a repeater station and a base transceiver station of a wireless communication system. Adjacent and co-channel interference can severely degrade the performance of the backhaul communication link. As a result, the conditions on the backhaul link channels can be continually monitored to ensure optimal performance of the link. Each RF channel on the backhaul communication link is individually diagnosed. A signal is then sent over the RF channel and the signal strength is measured along with any adjacent and co-channel interference. The measured statistics are then sent back to the base transceiver station. In a further embodiment of the invention, the power level of a RF carrier signal on the backhaul communication link is measured and the carrier signal is then turned off. The power levels on the adjacent channels—above and below are then measured.

Abstract: An approach to improving TDMA system operation is disclosed wherein in-band translator components are located in the center of remote cells which would normally contain a base transceiver system (BTS). The in-band. translators employ wireless in-band signaling for downlink transmission of commands from an operation and maintenance center (OMC) and uplink transmission of status-indicating and alarm signal data. The remotely located repeaters of the present invention have frequency shift key detection and demodulation capability incorporated in the downlink path, while also incorporating FSK modulation capability into the uplink path. This allows the repeater to extract commands from the serving BTS downlink signal and act on them. It also allows for the repeater to transmit status-indicating signals and alarms to the OMC via the uplink path to the serving BTS.

Abstract: A method and apparatus for dynamically controlling signal power levels in a bi-directional backhaul communication link between a base station and a repeater station is provided. The signal power level of a signal transmitted between a base station and a repeater station is measured at the receiver of the signal. Once the received signal power level has been measured, the power level data based on the received signal power level is automatically transmitted from the receiving station back to the source of the measured signal over the backhaul link. Upon receipt at the source, the power level data is extracted and analyzed to determine if the source needs to alter its transmitted power. Once the power level data is analyzed to determine if a change in the transmitted power is required, the source can automatically respond by increasing, decreasing, or maintaining the transmitted power.

The system includes a central processing unit for exclusively allocating one or more of the ARFCNs to each of the sectors, each sector providing a communication link for subscriber calls in one or more communication cells serviced by the BBS. Further, the system includes programming and hardware for exclusively allocating an additional one of the ARFCNs to the sector upon a number of the subscriber calls in any such sector reaching a predetermined limit which exceeds a capacity for the ARFCN.

Abstract: In a conventional Time Division Multiple Access (TDMA) wireless system, the specified distance between a mobile unit and the base transceiver system (BTS) cannot exceed predetermined distances because of time slot synchronization constraints. Furthermore, the varying distances between mobile units and the BTS create timing differences in the random access control channel (RACCH) bursts in the initial uplink signal from the mobile stations. In this approach to extending TDMA system coverage, in-band translator components are located in the center of remote cells which would normally contain a base transceiver system. The in-band translators include a loop back circuit that permits a host BTS to measure the backhaul propagation time delay by sending test access signals between the host BTS and the distant in-band translators.

Abstract: A method and apparatus to manage RF power in a broadband transceiver station (BTS) that includes a multi-carrier common RF power source such as a multi-carrier power amplifier (MCPA), for maintaining carrier power at a prescribed level. The power is managed by a power banking agent which is a module of the BTS system software. On a new channel request, the power banking agent determines if the request can be satisfied at the requested level. Otherwise, the power banking agent determines if the channel request can be satisfied at a lower power level. The power banking agent also manages active channels by reclaiming power from channels requiring less power and/or by allocating more power to the channels requiring more power. If the power banking agent cannot satisfy a request, the power banking agent will queue the request until a later time in the event that additional power becomes available.

Abstract: Apparatus and method to perform the real-time correction of differential non-linearities in a broadband wireless transceiver system using a digital look-up table. Initially, the values for the digital look-up table are determined prior to full operational use of the broadband transceiver system. The one set of values represents inverse response of the transfer function of the D/A converter. The other sets of values represents the inverse response of the transfer function for each A/D converter. The inverse response values for the D/A and A/D converters are stored in a non-volatile memory. During initialization of the broadband transceiver system, the values of the inverse response of the transfer function for the D/A converter are transferred from the non-volatile memory to a high speed memory. The values of the inverse response of the transfer function for each A/D converter is also transferred to another set of high speed memory.
