20080181182, Jul 31, 2008

Filed:

Jan 10, 2008

Appl. No.:

12/008344

Inventors:

Scott Carichner - Rancho Santa Margarita CA, US
Anthony Demarco - Newport Beach CA, US

International Classification:

H04J 3/00
H04J 3/06

US Classification:

370336, 370350

Abstract:

An improved digital radio head system and method for wireless communications is disclosed that simplifies the timing and synchronization between the access network, base station, and radio head. A satellite derived timing source is obtained at one or more of the remote radio heads where it is convenient to obtain and use the timing reference. The reference is transmitted back to the base station, if necessary, to synchronize the two. This is further synchronized at a lower accuracy through the access network.

Inventors:

- Irvine CA, US
Leonid Matytsine - Irvine CA, US
Anthony DeMarco - Leadville CO, US

International Classification:

H01Q 15/02
H01Q 3/08

Abstract:

An antenna has multiple RF elements disposed about a lens in at least two tracks. The at least two tracks collectively subtend more than 360 about the lens, providing highly customizable, adaptable, and steerable wireless communication. An array of multiple lenses and tracks is also contemplated.

Inventors:

- Irvine CA, US
Leonid Matytsine - Irvine CA, US
Anthony DeMarco - Leadville CO, US

International Classification:

H01Q 15/02
H01Q 21/00

Abstract:

A lens elements array comprises at least two lens elements aligned along an alignment axis. Each lens element includes a spherical lens and a feed element. The feed elements are tilted such that the RF signals generated by the feed elements have major axes form an angle (preferably between 5 and 30) other than a perpendicular angle with respect to the alignment axis. The combined RF signals produced collectively by these feed elements have amplitude that has minimal dips across the array. The feed elements that are farther away from the center of the array have higher levels of tilts than the feed elements that are closer to the center of the array.

H01Q 1/36

Abstract:

A radio frequency antenna uses an array of spherical lens and mechanically movable radio frequency (RF) elements along the surface of the spherical lens to provide cellular coverage for a narrow geographical area. The antenna includes at least two spherical lens, where each spherical lens has at least one associated element assembly. Each element assembly has a track that curves along the contour of the exterior surface of the spherical lens and along which a radio frequency (RF) element can move. The antenna also includes a phase shifter configured to adjust a phase of the signals produced by the RF elements. The antenna includes a control mechanism configured to enable a user to move the RF elements along their respective tracks, and automatically configure the phase shifter to modify a phase of the output signals from the elements based on the relative positions between the RF elements.

Abstract:

An antenna includes a stack of cylindrical lenses combined with feed elements to provide multi-beam coverage for a given wireless communication sector. Each cylindrical lens disc has approximately the same height as the feed elements being used with the lens. To overcome the problem of interference from cables and opposing feeds, feed elements are placed around the lens. The cylindrical lenses are stacked such that a small gap exists between each pair of adjacent cylindrical lenses, allowing for cable lines to pass through between the pair of the cylindrical lenses, and thus removing interference for 360 degree coverage. Cable lines are arranged such that they only traverse the portion of the circumferential surfaces of the cylindrical lenses that do not interfere with the field of view of the RF signals generated by the corresponding feed elements.
