Abstract: Systems and methods for peer group diagnosis detection are disclosed. In an example embodiment, a beam profile including a plurality of satellite beam characteristics is determined. A peer group of satellite terminals is determined. Terminal profiles with terminal characteristics for the satellite terminals in the peer group are determined. A normalized baseline profile including normalized terminal characteristics for the peer group is determined. Measured operational statistics of the satellite terminals in the peer group are received and converted into normalized operation statistics using the terminal profiles and the normalized baseline profile. Normalized peer group operational statistics including a mean and a standard deviation of normalized operational statistics are determined. A normalized deviation of the normalized operational statistics is determined for each satellite terminal. The normalized deviations for each satellite terminal are compared to a threshold deviation.

Abstract: Terminal diagnosis self correction is disclosed. A service inquiry is received regarding a problem with a terminal from a user. Terminal statistics are obtained remotely from the terminal and stored in a site diagnosis log. An initial diagnosis is determined with a site diagnostic tool using the terminal statistics. The initial diagnosis is stored in the site diagnosis log. A technician is dispatched to repair the terminal. Terminal statistics are obtained locally at the terminal and stored in an onsite validation tool log. An onsite diagnosis is determined using an onsite validation tool and stored the onsite validation tool log. The initial and onsite diagnoses are compared. In response to a difference between the initial and onsite diagnoses, the remotely and locally obtained terminal statistics are compared. The site diagnostic tool is adjusted based on the initial diagnosis, the onsite diagnosis, and the remote and local terminal statistics.

Abstract: A communications system includes a base station that is configured to transmit a signal that is modulated according to a predetermined modulation scheme and an orthogonal frequency division multiplexing scheme, wherein the signal is encoded using space-frequency coding. The base station includes a plurality of multiple-input multiple-output (MIMO) transceivers. The system includes a terminal that is configured to receive the modulated signal. The above arrangement is particularly applicable to providing multichannel multipoint distribution services (MMDS) over a radio communications system.

Abstract: An approach is provided for managing bandwidth in a data network. Capacity is allocated on a communication channel, which can be utilized for transporting data traffic or support network administrative functions (e.g., ranging), for a terminal to transmit data over the communication channel. In anticipation of the terminal having to transmit additional data, additional capacity is allocated on the communication channel for the terminal prior to receiving a request for bandwidth by the terminal. The anticipatory allocation is determined according to loading of the data network. This approach as particular applicability to shared capacity systems, such as a satellite communication system.

Abstract: An approach is provided for generating a frequency reuse plan for use in a radio communications system. A metric is calculated metric based upon an initial frequency reuse plan that specifies frequency assignments to a plurality of sectors. Each of the plurality of sectors is associated with a signal level value. The plurality of sectors are ordered based upon the corresponding signal level values. The frequency assignments are iteratively modifying to improve the metric according to the order of the plurality of sectors. The present invention has application to radio communications systems.

Abstract: An approach for providing power control of a radio terminal is disclosed. A first control loop is performed according to a first set of signal parameters (e.g., signal-to-noise level) to adjust power level of the radio terminal based upon a received signal from the radio terminal. Further, a second control loop is performed according to a second set of signal parameters (e.g., raw bit error rate (BER)) to refine the power adjustment of the first control loop. The present invention has particular applicability to a point-to-multi-point or a point-to-point radio system.
