A method and system for optimizing a core voltage level of a portable computing device ('PCD') and enhancing frequency performance of individual subcomponents are disclosed. A plurality of voltage values is determined for a plurality of subcomponents within the PCD. Next, a reduced set of voltage values may be calculated with a voltage aggregator based on the plurality of voltage values. An optimized voltage level for a shared power domain may then be determined by a voltage optimizer within the PCD from the reduced set of voltage values. A shared power domain may then be set to the optimized voltage level. Subsequently, an operating frequency of each subcomponent may be optimized with a frequency performance enhancer based on the optimized voltage level. An optimal power collapse duration may also be calculated by the frequency performance enhancer and set for each subcomponent from the optimal frequency.

A control interface protocol governs communications in a satellite telephone system. The satellite telephone system comprises a radio antenna unit (RAU) and a plurality of desksets connected to the RAU. An interface bus connects the desksets to the RAU. The RAU and the desksets communicate with each other by packets. Each packet comprises a start of header (SOH) byte, an address number (ADDR) byte, a command (CMD) byte, an argument (ARG) and a block check character (BCC). The ADDR byte comprises a source and a destination address of the packet. All packets, except negative acknowledgment (NAK) packets from the desksets, are acknowledged by the RAU. The packets originating from the desksets are tagged with an address of the desksets. A packet to a specific deskset includes a destination address. A packet originating from the RAU to all desksets includes a first default address. A packet originating from the RAU to a deskset that does not have an address includes a second default address.

Techniques to test a wireless communication link using configurable channels and rates. A W-Markov test service may be invoked to test and/or verify the performance of the downlink and/or uplink using at least one transport channel for each link. Each transport channel may be individually configured. The W-Markov test service supports generation of test data based on a defined data sequence or a pseudo-random number generator. The testing may be performed based on a particular deterministic or pseudo-random activity model. For voice call testing, a first-order Markov model may be used to model voice activity and to select the rate to use for each transmission time interval (TTI). For Adaptive Multi-Rate (AMR), testing may be performed based on configurable AMR rates and silence descriptor (SID) types. The test data generation processes are synchronized between the transmitter and receiver. Bit, frame, and/or block error rates and other statistics may be collected.

A Wireless Communication Device (WCD) includes multiple fingers that track one or more tracked transponder beams. Each tracked beam is from a respective tracked transponder. The WCD determines a tracked-beam searcher energy for each of the tracked beams, and an untracked-beam searcher energy for each of one or more untracked beams from each of the tracked transponders. The WCD attempts to determine a preferred one of the untracked beams that should become a tracked beam. This determination is made based on the tracked-beam and the untracked-beam searcher energies. The WCD assigns, or alternatively, reassigns, a finger to the preferred untracked beam when the attempt to determine a preferred untracked beam is successful. The transponders may be satellites or base stations.

A system and a method for address assignments for wireless satellite telephone systems comprises one or more desksets (telephones) and a radio antenna unit (RAU). The desksets are connected to the RAU using an interface bus. In operation, a deskset initiates an address arbitration cycle by transmitting a request for an address to the RAU. The RAU acknowledges after it receives the request, and queries other desksets if the requested address is being used by other desksets. If no other deskset responds within a predetermined time period, the RAU grants the requesting deskset the address. If the requested address is being used, the deskset using the address informs the RAU, and the RAU rejects the request. The requesting deskset then requests a different address. If all available addresses are being used, the requesting deskset informs the user and shuts down. If two or more desksets transmit requests concurrently, there will be a collision. To resolve a collision, the desksets are divided into two sets. Desksets with a 0 in the least significant bit (LSB) of their electronic serial number (ESN) will be in a first, and the desksets with a 1 in the LSB of their ESN will be in the second set. The desksets in the first set transmit after 100 ms. The desksets in the second set transmit after an additional 10 ms (110 ms total).
