摘要： A method for reducing errors in streaming data over a wireless link that aligns data frames with wireless packets. The method is especially suitable for a wireless link that requires a uniform packet size and prohibits re-transmission of packets. One embodiment aligns a start of a data frame with a first wireless packet, transmits a beginning portion of the data frame in the first wireless packet over a wireless link, inserts into a second wireless packet an ending portion of the data frame along with fill data sufficient to fill the second wireless packet, and transmits the second wireless packet over the wireless link. A further embodiment includes synchronization markers at the start of the beginning portion and the ending portion.

摘要： Systems and methods are provided for routing data messages between a cellular telephone and a cordless telephone system having a plurality of cordless handsets configured to communicate with a single cordless base station when in range. Messages are received at the cordless base station via a first radio frequency transfer protocol. The message is transmitted to the cordless base station from the cellular telephone after the cellular telephone has received the message from a cellular network. The cordless base station transmits the message to a desired one of the plurality of cordless handsets via a second radio frequency transfer protocol. The desired one of the plurality of cordless handsets is chosen based on predetermined message routing settings.

摘要： Systems and methods of enhanced real-time communications between WiFi devices. In one embodiment of the present invention a method for enhanced payload protection in a WiFi system includes transmitting multiple copies of data packets in successive frame body transmissions. In another embodiment, a method for enhanced communications over a WiFi link includes examining a unit ID packet to determine a destination of a data payload when errors are detected in IP and/or MAC headers. If a destination is determined, the packet is corrected and forwarded to the device based on the unit ID determination. In another embodiment, a method for enhanced real-time communications in a WiFi network includes establishing a communications frame that includes an active timeslot, preferably based on U-APSD, for a WiFi device to use for transmission of successive audio data packets transmitted between the WiFi handset and AP.

摘要： A system and method for improved data transmission in a WDCT frame structure. A transmission slot in a WDCT frame of conventional size is configured for transmission of data bits having substantially smaller data bit width than used in conventional WDCT frames. A user data field is configured to transmit a larger data payload by including more bits within the user data field. In one implementation, the user data field is configured for transmission of multiple copies of a voice data packet at the same rate as single data packets are transmitted in a conventional WDCT frame structure. In another implementation, a non-voice data transmission rate is increased by more than a factor of two over conventional WDCT frame structure.

摘要： A hybrid cordless telephone system allows a user to place or receive a call over either a data network or a PSTN network. In one aspect, a system router and PSTN unit are coupled with a communications manager to avoid extensive redesign of router components and PSTN components while providing a wireless user with data network and PSTN connectivity. In another aspect, the system router of the hybrid cordless telephone system includes a communications manager configured to provide termination of data network calls or PSTN calls at the system router. Accordingly, a plurality of handsets can each access the system router to place or receive calls from the data or PSTN networks.

摘要： A cordless telephone implementing using a BLUETOOTH wireless bearer is presented. A BLUETOOTH voice data structure is implemented by coding the voice data at a bitrate below 64 kb/s, such that the full number of payload bits provided by the BLUETOOTH voice data structure are not required for transmission of voice data. The packet payload is then encoded in a non-standard format to implement a robust error detection and/or correction protocol for the voice data, as well as for the provision of a low-rate data channel for transmission of information such as caller ID. Alternatively, a BLUETOOTH non-voice data structure can be employed by transmitting encoded voice data as user payload bits. The data link is then flushed each time new voice data is ready for sending by the transmitting device. If slots are available before the data link is flushed, unsuccessfully transmitted data can be automatically resent, thereby implementing time and frequency diversity.

摘要： A system for allowing BT, WDCT, and 802.11 transceivers to operate in close proximity with a minimum of interference, is disclosed. In an exemplary embodiment, a method for avoiding interference between a first FHSS device and other RF devices using 802.11 or FHSS protocols is disclosed. The first FHSS device initially detects the presence of an interfering RF device (“interferer”), for example a device employing 802.11 protocol, and adjusts the frequency of channels used for operation of the first device accordingly to avoid overlap with the 802.11 band. In the presence of an additional interferer, for example, a second FHSS device emitting an interfering signal, the first FHSS device may segregate its operation channels to achieve maximum frequency separation from an 802.11 and second FHSS device. In addition, the first and third devices may also multiplex their transmit/receive timing to avoid interference in time domain. By avoiding interference in time domain, first and third device can occupy the same channels in the frequency band achieving further frequency separation from the 802.11 device.

摘要： A method and system for transmitting and receiving a control data signal within spreading signal and an intelligence/analog signal. The control data is interleaved within the spreading data signal at a transmitter side. Before transmitting to a remote receiver side, the spreading/control data signal, after passing a high-pass filter, and an intelligence signal, which is passing through a low-pass filter, are summed by a summing device to form a composite intelligence/spreading data (CISS)signal and are modulated on an RF carrier by a modulator. After receiving the CISS modulated RF carrier, the receiver side converses the CISS modulated RF carrier to IF signal, which is then demodulated by a demodulator to recover the original CISS signal. The CISS signal is then passing through a low-pass filter to recover the intelligence signal and through a high-pass filter to recover the spreading/control signal. The control signal is further recovered by a digital device.
