Publication number: 20120231737Abstract: A method (300, 400) for communicating RF signals from a mobile station (100). The method can include detecting whether the mobile station or a first antenna (105) of the mobile station is proximate to an object. Responsive to detecting that the mobile station or the antenna is proximate to the object, RF energy being communicated by the mobile station can be distributed among the first antenna and at least a second antenna (110). Distributing the RF energy can include equally distributing the RF energy among the first antenna, the second antenna and/or any additional antennas. Distributing the RF energy also can include unequally distributing the RF energy among the first antenna, the second antenna and/or any additional antennas.Type: ApplicationFiled: March 15, 2007Publication date: September 13, 2012Applicant: MOTOROLA, INC.Inventors: Lorenzo A.

Publication number: 20120135735Abstract: A method for facilitating a mobile station to perform a fast handoff in a wireless communication system allows a handoff procedure to be anticipated (by the mobile station, its serving base station, or both) based on historical information regarding prior successful handoff procedures. In operation, the serving base station monitors (510) current mobile station parameters and compares them with historical data. If the parameters indicate a high probability target base station (515), the serving base station requests allocation (525) of air interface resources at the high probability target base station prior to the mobile station reporting reception of signal from the high probability target base station. This facilitates fast handoff from the serving base station to the high probability target base station.Type: ApplicationFiled: February 9, 2012Publication date: May 31, 2012Applicant: MOTOROLA MOBILITY, INC.Inventors: Lorenzo A. Ponce De Leon, William P. Alberth, JR.

Patent number: 8140076Abstract: A method for facilitating a mobile station to perform a fast handoff in a wireless communication system allows a handoff procedure to be anticipated (by the mobile station, its serving base station, or both) based on historical information regarding prior successful handoff procedures. In operation, the mobile station receives a neighbor list from a serving base station and determines whether a member base station of the neighbor list is a successful target base station based on historical data. If the member base station is not a successful target base station, the mobile station scans the member base station, measures a signal quality associated with the member base station, and sends a measurement report for the member base station when the signal quality meets a standard signal quality threshold. If the member base station is a successful target base station, the mobile station sends the measurement report for the member base station when the measured signal quality meets a lower signal quality threshold.Type: GrantFiled: December 17, 2007Date of Patent: March 20, 2012Assignee: Motorola Mobility, Inc.Inventors: Lorenzo Ponce de Leon, William P.

Patent number: 7705787Abstract: A coupled slot probe antenna for use with antenna structures in mobile communication devices, such as cellular telephones and other wireless communication devices. The coupled slot probe antenna includes at least one first conductive element, and a second conductive element coupled between the first conductive element and the printed circuit board (PCB) ground plane of the mobile communication device. The first and second conductive elements define a tunable coupled slot area and the coupled slot probe antenna is coupled to the PCB ground plane in such a way that the coupled slot area is near a low-impedance point of the antenna structure, wherein coupling therebetween improves the bandwidth and the efficiency of the antenna structure. The coupled slot area can be tuned by changing the size of the coupled slot area and by changing the position of the coupled slot area relative to the low-impedance point of the antenna structure.Type: GrantFiled: March 26, 2007Date of Patent: April 27, 2010Assignee: Motorola, Inc.Inventors: Lorenzo A.

Publication number: 20090061862Abstract: If the mobile station (101) locates a peer it will request network metadata and may obtain location related services or service lists. The mobile station (101) negotiates with one of more peers (103) to share the work load of background scanning for network services. After successful negotiation, any peers in the “discovery net” will report or advertise to each other of any newly discovered networks, or networks to which connectivity has been lost. Since the various mobile stations may, when powered on, scan periodically for network changes, the metadata stored on the mobile station (101) will be dynamic and will change periodically upon travels and/or encounters with additional peers. Because the peers (103) may also possess location information, the mobile station (101) may additionally adjust its scan to prioritize services advertised by those members of peers (103) that are located most proximate to the mobile station (101).Type: ApplicationFiled: August 30, 2007Publication date: March 5, 2009Inventors: William P.

Patent number: 7304613Abstract: A bowtie monopole antenna is fabricated of a sheet metal radiating body 102 that is triangular shaped, and having a longitudinal dimension and axis (106) and a width (108). One corner of the radiating body is tapered to form a feed point (104). The length dimension determines the antenna's lowest resonance frequency while the taper created by the width determines the highest point of resonance. For using the bowtie monopole antenna in a communication device, the radiating body (102) is folded or wrapped around towards itself To facilitate the folding or wrapping a mounting substrate (202) is used. The substrate may be provided with retaining features (206) to capture the antenna assembly within the communication device.Type: GrantFiled: June 21, 2004Date of Patent: December 4, 2007Assignee: Motorola, Inc.Inventors: Adam R.
