  • Publication number: 20020094797
    Abstract: A communications system comprises a beacon and at least one portable device for receiving data from the beacon. The beacon broadcasts messages using a first protocol which provides a series of inquiry messages which hop frequencies (such as Bluetooth). Additional data is broadcast using a spread spectrum transmission technique. These two modes enable the spread spectrum transmission technique to be used to enable an unsynchronized receiver to establish communication in a short time, so that data can be sent to the receiver as quickly as possible. The frequency hopping technique may require a longer call set-up procedure, but provides a more appropriate communications protocol for bi-directional transfer of larger quantities of data.

  • Publication number: 20020004375
    Abstract: An antenna diversity receiver comprises a zero-IF receiver connected to two antennas (102a, 102b) via switches (532,534). Simultaneous measurement of signal qualities from both antennas is possible by routing signals from the first antenna (102a) via a first mixer (106) and channel filter (116) and routing signals from the second antenna (102b) via a second mixer (108) and channel filter (118). A diversity controller (536) compares the signal qualities received from the antennas (102a,102b) during a data preamble to select a preferred antenna, then adjusts the switches (532,534) to route the signals from the preferred antenna to both input mixers (106,108). The amplifier (104a,104b) connected to the deselected antenna may be switched off during data reception, thereby minimizing extra power consumption.

  • Publication number: 20010055356
    Abstract: A multicast radio data communication system comprising a master and a plurality of slave stations uses a retransmission protocol. Data (13) is transmitted by the master station and received by the slave stations. Slave stations having the weakest radio link are designated primary stations, and all other slaves are designated secondary stations. Any slave station may transmit a negative acknowledgement but only the primary stations may transmit a positive acknowledgement. Positive acknowledgements are transmitted in separate time slots (1,2,3,4), but negative acknowledgements (9,10) transmitted by the secondary stations overlap the positive acknowledgements transmitted by primary stations. These negative acknowledgements corrupt reception of the positive acknowledgement by the master station, thereby ensuring that the data is retransmitted.

  • Publication number: 20010051529
    Abstract: A multicast radio data communication system comprises a master and a plurality of slave stations, and uses a retransmission protocol. Data (10) is transmitted by the master station simultaneously to all slave stations. Each slave station acknowledges in turn in a respective time period (13 to 16) which may be assigned by the master station or pre-set. If the master receives a positive acknowledgement from each slave station, the master proceeds to transmit new data. If the master receives a negative acknowledgement from any slave station, or fails to successfully receive any acknowledgement from any slave station, the master station retransmits the previously transmitted data.

  • Publication number: 20010046875
    Abstract: A multicast radio data communication system comprising a master (1) and a plurality of slave stations (2, 3, 4), and using a retransmission protocol. Data is transmitted by the master station and received by the slave stations. One slave station is designated the primary slave station, and all other slaves are designated secondary slave stations. Any slave station may transmit a negative acknowledgement but only the primary slave may transmit a positive acknowledgement. Positive and negative acknowledgements are transmitted substantially simultaneously. Negative acknowledgements corrupt reception of the positive acknowledgement by the master station, thereby ensuring that the data is retransmitted. The primary slave station is selected to have the lowest quality radio link, which may be ensured by a power control command from the master.
