Abstract: An apparatus and method are disclosed to receive location data identifying the current location of a vehicle, for example an automobile or aircraft. A database, storing radio device records, is then queried. Each radio device record in the database identifies a radio device and its location. Radio device records associated with radio devices likely to be within communication range of the vehicle may then be retrieved from the database. The radio device records may be used to generate information for individual ones of radio devices which are likely to be within range of the vehicle and display that radio device information to a vehicle operator via an electronic display. The display may be updated as the vehicle travels to display radio device information as the radio devices come into range of the vehicle and remove radio device information from the display as the vehicle travels out of range.

Abstract: A method for pointing an antenna at an inclined geostationary satellite includes obtaining an analemma of the inclined geostationary satellite, and determining a plurality of points that are to be searched, wherein determining the plurality of points comprises selecting points that follow a centerline of the analemma. One point of the plurality of points is selected and the antenna is pointed at the selected point. While the antenna is pointing at the selected point, the inclined geostationary satellite is queried an RF power level of a response to the query received from the inclined geostationary satellite is recorded. Another point of the plurality of points and the query/recording step is repeated for each of the plurality of points. A determination is made regarding which point of the plurality of points produced a response to the query having the highest power level. The antenna then is pointed at the point having the highest power level.

Abstract: A power saving wire-free earpiece has a Bluetooth transceiver and a Bluetooth Low Energy (BLE) transceiver. A stream of audio from a remote source is separated into a local audio stream and a stream sent to the BLE transceiver for a remote earpiece. The earpiece is operative in a first and second mode, the first mode enabling the BT transceiver and BLE transceiver, the second mode enabling only the BLE transceiver for receiving remote streams of data. The first and second mode alternate so that the local and remote earpiece have substantially uniform current requirements.

Abstract: A station (STA) may receive a wireless signal including a preamble of a packet. An energy level of the signal received may exceed a clear channel assessment (CCA) threshold. The STA may determine, using a carrier sense multiple access (CSMA) protocol, to ignore a payload portion of the packet based on information contained in the preamble and adjust the CCA threshold to account for the payload portion of the packet. The STA may then access a wireless medium using the CSMA protocol during the payload portion of the packet using the adjusted CCA threshold. In an example, the STA may receive the preamble of the packet via a beamformed signal. In another example, the STA may receive the preamble of the packet via an omni-directional signal. In a further example, the CCA threshold may be a received signal strength indicator (RSSI) level.
