US Patent:

7925266, Apr 12, 2011

Filed:

Jun 15, 2006

Appl. No.:

11/455162

Inventors:

Thuy Thomas Tran - Fairfax VA, US

Assignee:

Nextel Communications Inc. - Reston VA

International Classification:

H04W 40/00

US Classification:

455446, 455448, 455423

Abstract:

The coverage radii for a number of wireless transmission stations is calculated based on one or both of a link budget analysis and a propagation model. At least one coverage gap may then be identified within a given coverage area of a communications network, and locations selected for new wireless transmission stations based on a location selection criteria. The previously-identified coverage gap information is updated to take into account the wireless coverage to be provided by the new wireless transmission station, after which additional passes of the coverage area may be performed to identify locations for additional new wireless transmission station based on both the location selection criteria and on the updated coverage gap.

Appl. No.:

11/961385

Inventors:

John Y. Kim - Centreville VA, US
Thuy Tran - Fairfax VA, US

Assignee:

Sprint Spectrum L.P. - Overland Park KS

International Classification:

G06G 7/76

US Classification:

701117

Abstract:

Methods and systems are disclosed for monitoring vehicular traffic congestion through the use of inter-vehicle communication and traffic chain counters. Data packets including counter, vehicle identification, direction, location, and speed information are transmitted between vehicles via short-range wireless communications. A receiving vehicle edits a data packet if the data packet reflects that the receiving vehicle has not yet edited the packet and is traveling in substantially the same direction as the vehicle which transmitted the packet to the receiving vehicle. If a receiving vehicle is the last vehicle to edit a packet, the receiving vehicle transmits a reporting packet to a traffic monitoring server via long-range wireless communications.

Appl. No.:

12/028454

Inventors:

John Y. Kim - Centreville VA, US
Thuy Tran - Fairfax VA, US

Assignee:

Nextel Communications Inc. - Reston VA

International Classification:

G01R 31/08

US Classification:

370252, 370250

Abstract:

Systems and methods are provided for evaluating an effect of a simulated communication network to media data. The method includes encoding media data to produce a plurality of packets, each packet being associated with a packet index number, a packet size and a packet transmission time. The packet index number, packet size and packet transmission time for each of the plurality of packets can be input to a communication network simulator to create trace packets corresponding to the plurality of packets. The communication network simulator output indicates at least one effect of the simulated communication network to input trace packets.

Appl. No.:

11/455021

Inventors:

Thuy Thomas Tran - Fairfax VA, US

Assignee:

Nextel Communications, Inc. - Reston VA

International Classification:

H04W 40/00

US Classification:

455446, 455447, 455448, 455449

Abstract:

Methods for decommissioning wireless transmission sites include calculating coverage radii for wireless transmission stations, and representing the wireless transmission stations as a two-dimensional grid. In one embodiment, the virtual cells that comprise the grid having a virtual cell size that is based on the coverage radii. Virtual grid cells having excess wireless transmission stations are identified. Particular excess wireless transmissions stations are then selected for decommissioning based on a predetermined factor.

Appl. No.:

12/575691

Inventors:

John Yongchae Kim - Centreville VA, US
Joe Martire - Herndon VA, US
Thuy Thomas Tran - Fairfax VA, US

International Classification:

H04W 4/00

US Classification:

370328

Abstract:

The present document describes a system and method for extending a wireless communication coverage area of a cellular wireless base station transceiver (BTS) to enable control signaling and identification of mobile stations not currently within a coverage area of an existing beamform antenna pattern of the BTS, for example. A cellular BTS may scan through dead zones of coverage areas provided by the BTS to identify mobile stations not within the coverage area of the BTS, but within a possible service area of the BTS. In addition, the BTS may receive a relaying control signal from a mobile station located within the coverage area of the BTS, and the signal will indicate a location of another mobile station not within the coverage area of the BTS but within the service area of the BTS. In either example, the BTS may attempt to provide a coverage area to the mobile station located in the control signaling dead zone, for example.
