摘要： A system and method are provided for creating a picocell service alternate to a wireless network service. The method comprises: detecting a multiple access (MA) wireless communications network, such as a terrestrial or satellite network; and, generating a first picocell in a response to detecting the MA wireless network. Typically, the method comprises receiving requests for picocell service from mobile stations, in response to generating the first picocell. In one aspect, the service requests made by the mobile stations are denied. In another aspect, the method further comprises: establishing a first picocell MSC; and, providing network services to mobile stations via the first picocell, in response to the requests for picocell service. For example, the first picocell MSC may provide the same network services that are provided by a conventional terrestrial network, for example. Alternately, the method establishes an alternative wireless network (a second picocell) to provide services.

摘要： A power-efficient wireless device is equipped with multiple (N) antennas. Each antenna is associated with a transmitter unit and a receiver unit. The wireless device also has processing units used to perform various digital processing tasks. The transmitter units, receiver units, and processing units may be selectively enabled or disabled. In an idle state, the wireless device may enable only a subset (e.g., one) of the N receiver units and one or few processing units for signal detection and acquisition. For active communication, the wireless device may enable Ntx transmitter units for data transmission and/or Nrx receiver units for data reception, where 1≦Ntx≦N and 1≦Nrx≦N. The enabled processing units may also be clocked at a lower frequency whenever data is transmitted or received at a data rate lower than the highest data rate. The wireless device may go to sleep whenever possible to conserve power.

摘要： A mobile electronic device includes an earphone/microphone port, an I/O circuit to receive a modulated data signal from data input devices via the earphone/microphone port, and a processor unit programmed to extract data from the modulated data signal. The processor unit (or the I/O circuit) detects connection of a device to an earphone/microphone connector of the mobile electronic device and determines whether the connected device is a data input device. If the connected device is a data input device, the processor unit is programmed to extract data from modulated data signals generated by data input device.

摘要： Systems, methods and apparatus for configuring and accessing a random access channel in a CDMA communication system are disclosed. The number of users supported by a random access channel can be optimized by assigning a distinct time of arrival to each of a plurality of users. Each of the users can be time synchronized and can transmit data at a time that compensates for a propagation delay to allow the data to arrive at the destination receiver at the assigned time. In a CDMA system, each of the users can transmit data that is spread with the same spreading code, provided the cross correlation properties of the code are sufficient to allow identification of a source that is time offset relative to another user. The time of arrival can be determined based on the number of active users, and can be assigned as often as each transmission by each user.
