20080227494 | Method For Transmitting A Sound-Film Message From A Mobile Terminal To Any E-Mail Address - The invention relates to means for mobile communications and transmission of data via electronic mail. | 09-18-2008 |
20080311957 | ESTABLISHING WIRELESS LINKS VIA ORIENTATION - A system for establishing a wireless link from a wireless communication device (WCD) to at least one target device. The process of both identifying the target device and establishing a link to this device may incorporate the orientation and/or movement of the WCD into the procedure in lieu of the extensive use of traditional menu interfaces. A WCD may interpret a combination of orientation and/or movement as an approximate target device location that may be utilized to narrow the total population of all located devices into a subset containing those devices located within of near the approximate target device location. The subset of devices may be formulated and displayed as potential target devices for selection by a user. If any of the potential target devices are known by the WCD, a link may be established automatically. | 12-18-2008 |
20100016021 | BASE BAND PROCESSING MODULE N+M BACKUP METHOD BASED ON SWITCHING AND DEVICE THEREOF - The present invention discloses a base band processing module N+M backup method based on switch, is characterized in that: a switch unit is added between RF transceiver unit and base band processing unit, and IQ signal forwarding between base band processing modules of the base band processing unit and RF transceiver modules of the RF transceiver unit is performed by the switch unit; handing over the functions of the base band processing module in trouble to a backup base band processing module by resetting the switch unit and modifying the path of receiving and transmitting IQ signal, therefore realizing the N+M backup for base band processing module. The present invention can effectively realize the N+M backup for the base band processing module by adding a switch unit, therefore solving the technical problem of complexity and high cost for wiring and interfacing when having a large number of BBP and TRX modules. | 01-21-2010 |
20140179374 | Switch Circuit and Method of Switching Radio Frequency Signals - An RF switch circuit and method for switching RF signals that may be fabricated using common integrated circuit materials such as silicon, particularly using insulating substrate technologies. The RF switch includes switching and shunting transistor groupings to alternatively couple RF input signals to a common RF node, each controlled by a switching control voltage (SW) or its inverse (SW_), which are approximately symmetrical about ground. The transistor groupings each comprise one or more insulating gate FET transistors connected together in a “stacked” series channel configuration, which increases the breakdown voltage across the series connected transistors and improves RF switch compression. A fully integrated RF switch is described including control logic and a negative voltage generator with the RF switch elements. In one embodiment, the fully integrated RF switch includes an oscillator, a charge pump, CMOS logic circuitry, level-shifting and voltage divider circuits, and an RF buffer circuit. | 06-26-2014 |
20140221045 | Method and system for switching wireless devices in looped network - The disclosure discloses a method and system for switching wireless devices in a looped network. The wireless devices include a core wireless device and remote wireless devices, and the core wireless device and two or more remote wireless devices, connected through two ports of the core wireless device, constitute a looped network; the method including: when the core wireless device detects that a line error rate at each of the two ports is within a determined threshold range, the core wireless device sends a valid control character, otherwise, the core wireless device sends an invalid control character; wherein the valid control character sent at one of the two ports of the core wireless device is different from that sent at another of the two ports of the core wireless device; when the remote wireless device detects that a line error rate at a receiving end of a master port of the remote wireless device is within the determined threshold range, the remote wireless device forwards the valid control character received at a slave port to the master port, otherwise, the remote wireless device sends the invalid control character to the master port; and the remote wireless device sends the invalid control character to its slave port continuously. With the present disclosure, the stability of the networking mode through the RRUs is promoted. | 08-07-2014 |
20150094117 | TRANSCEIVER FRONT END WITH LOW LOSS T/R SWITCH - A transceiver or RF front end employing a transformer with a low loss transmit/receive (T/R) switch circuit in the ground path. In various embodiments, differential outputs of a power amplifier are coupled to the first winding of the transformer, while the input of a low noise amplifier is coupled to the second side of the transformer via a matching inductor. The T/R switch circuit, which may be a thin oxide CMOS transistor, is coupled between the second side of the transformer and ground. In operation, the T/R switch circuit may be enabled during transmit mode operations of the power amplifier, such that a low impedance path to ground is provided at the input of the low noise amplifier, thereby protecting it from high voltage swings generated by the power amplifier. | 04-02-2015 |
