Abstract: When a user inputs necessary details on a user's decision screen and transmits the inputted details (Step S3), an acceptance server 12 reads an address list from an address DB 21 and then transmits the address list to the user (Step S4). When the user selects an address from the address list and transmits the selected address, an area decision server 13 retrieves and reads a map of the surrounding of the selected address from a map DB 23 and transmits the map to the user (Step S6). The user then inputs the numbers of stories of a building where the user desires to utilize the wireless communication service and the direction of an antenna based on the map of the surrounding, and transmits those inputted particulars (Step S7). The area decision server 13 reads base station information from a base station DB 24 and calculates the transmission characteristic between two points, namely the antenna and the base station, to decide whether communication between the two points is executable or not.

Abstract: A method for securing the operation of a receiver in a two-way radio apparatus by enhancing the isolation between the transmitter and receiver, and a radio apparatus employing said method. The transmitter and receiver in a radio apparatus have separate antennas (320, 330). The transmitter has at least two mutually alternative filters which have different attenuations in the receive band. Transmitting antenna matching is monitored by measuring the strength of the field (re) reflected from the antenna (320) towards the power amplifier (PA). When the strength of the reflected field in proportion to the strength of the propagating field is above a certain threshold, the filter (312) which has a greater stop-band attenuation in the receive band will be used as the transmitting filter. Otherwise, the filter (311) which has a smaller stop-band attenuation and, hence, smaller pass-band attenuation will be used as the transmitting filter.

For each radio unit 10˜40, the control unit 50 compensates a phase amount for generating a directivity pattern used for an output signal according to a difference in phase shift amounts between a transmission subsystem and a reception subsystem.

Abstract: The present invention provides an apparatus and system for accurately predicting and evaluating cellular system performance before an actual system is installed at a site. In accordance with an embodiment of the invention, only two persons (or under certain conditions, as few as one) are required to operate the portable measurement and antenna placement (MAP) tools of the invention, and evaluate system performance (e.g., voice quality) at varied locations of a site without the system being in place. A user can measure out the size of cells using a bar graph display that shows the range of acceptable signal levels for the system, and an audible warning tone that signals the user when the cell edge has been exceeded. In addition, other quality determinative system parameters (e.g., bit error rate (BER), etc.) can be evaluated simultaneously with voice quality and average received signal strength.

Abstract: A method and system for automatically completing international telephone calls using a pre-selected discount telephone service. An array of Pic I/O pin used to monitor a cell phone activity. When the dialing of an outgoing call is detected, a central processing unit, in conjunction with a DTMF decoder, determines whether the call being made is a discount call by detecting whether predetermined positioned digit(s) is a predetermined number or set of numbers. If the number dialed is a potential discount call, the DTMF generator dials a predetermined discount service provider number and/or access code resulting in completion of the call at a discounted rate.

Abstract: Apparatus, and an associated method, for controlling the power levels at which an EDGE-modulated signal, or other signal which includes envelope varying-portions, during operation of a communication system. Changes in the power levels of the EDGE-modulated signal are permitted when closed-loop power control is done on nonamplitude-modulated component portions of the signal. Changes in the power levels of the EDGE-modulated signal are prevented by open-loop power control on amplitude-modulated component portion of the signal.

Abstract: A geographical web browser allows a user to navigate a network application such as the Word Wide Web by physically navigating in geographical coordinates and roaming through coverage areas of wireless LANs, microcells, and other such local broadcast domains. A mobile unit communicates with a network server via an air interface that supports wireless packet data. The mobile unit receives a broadcast transmission from a local broadcast domain entity that uses a low power local wireless protocol. The transmission includes a data packet that includes an indication related to information content. A content-selective information filter then compares a content-based filter parameter with the indication in the packet and selectively passes information related to the packet when a match is identified. In response to the identified match, a user is notified and given the option to request the content to be coupled from the mobile unit to the network server.

Abstract: A method and system (102) provide adaptive modulation/coding with distribution of excess resources based on one or more system criteria. The system (102) may be any system with more than one modulation rate or more than one coding rate and may be a wireless communication system using CDMA, TDMA, OFDM or any other signal formats. Generally, the method determines excess resources of the system based on desired characteristics of links supported by the system. The excess resources may be any number of system resources, such as transmit power. These excess resources are then distributed to the links based on various system criteria, such as to increase system coverage, to increase system capacity, to modify a data rate profile of the system or to reduce interference in the system. Methods for providing such distribution of the excess resources are also provided for equal data rate systems.
