A mobile device (200) for receiving an audio signal from a source (390) via a base station (300) is disclosed. The mobile device comprises a first wireless communication interface (220) operable to communicate using a first mode of wireless communication; a second wireless communication interface (230)_operable to communicate using a second mode of wireless communication, the second mode having a shorter range than the first mode; and a controller (210) configured to switch from receiving the audio signal from the base station via the first wireless communication interface to receiving the audio signal via the second wireless communication interface when the mobile device is proximate to the base station.

A wired network may be used to carry signals for a wireless network, in a frequency-shifted manner, to extend the range of the wireless network. A wired network may detect signal interference emanating from a wireless service provider, and received through a leak in the wired network's infrastructure. Devices may be installed or leveraged in the vicinity of the interference to extend the wireless service to geographic areas that may have poor reception. The devices may amplify wireless downstream signals and transmit them wirelessly, and may receive upstream wireless communications and transmit them upstream in the wired network's protocol.

This invention is a telephone station for placement in the home or work environment which can send and receive telephone calls over CDMA & GSM communication bands and direct link satellite communication such as Iridium, Globalstar and other similar systems. By using both antennas inside the cellular handset and a CPU/Switching Hardware with a 3 channel switching device this product can work on every cellular market on earth. A cellular signal range extender is included to improve signal strength for areas with poor coverage. In addition, the inclusion of an internet router built-in to the base station will permit this device to connect to internet telephony services. To extend the functionality of this phone; we can embed a WiFi wireless internet.

There are provided a code reading unit for reading a code in a portable terminal, a first terminal side operating environment setting unit for analyzing a code, thereby acquiring first operating environment setting information required for connection to a relay device through Bluetooth and setting the first operating environment setting information to the portable terminal, a setting information generating unit 4 for generating second operating environment setting information required for connection to a telephone call control server through a wireless LAN to make a call, a second terminal side operating environment setting unit for setting the second operating environment setting information thus generated to the portable terminal, and transmitting the second operating environment setting information to the telephone call control server and registering the second operating environment setting information therein.

A cordless phone apparatus is provided, which includes one or more slave devices and a master device. The master device includes: i) a LAN transmitter configured to transmit slave device information to a wireless IP terminal via a wireless LAN, wherein the slave device information includes identification information of each slave device registered to the master device, ii) a receiver configured to receive from the wireless IP terminal selection of the identification information of a destination slave device and selection of transfer data including at least one of ringtone data, wallpaper data, and phone book data, iii) a transfer data converter configured to convert at least one of the ringtone data, wallpaper data, and phone book data included in the transfer data into a data format usable in the destination slave device, and iv) a cordless phone transmitter configured to transmit the converted transfer data to the destination slave device.

Embodiments disclose a base of a cordless digital telephone set and a cordless digital telephone set. In the base of a cordless digital telephone set, a subscriber circuit module and a Bluetooth module can establish, under control of a main control module, a communications channel for direct interconnection, thereby reducing workload of the main control module, and optimizing a transmission path of voice data. The base of a cordless digital telephone set in embodiments of the present invention includes a switch module. When receiving a first control signal that is sent by the main control module, the switch module connects a communication data output pin of the subscriber line interface circuit module to a communication data input pin of the Bluetooth module; and connects a communication data input pin of the subscriber line interface circuit module to a communication data output pin of the Bluetooth module.

There are provided a code reading unit 1 for reading a code in a portable terminal 10, a first terminal side operating environment setting unit 2 for analyzing a code, thereby acquiring first operating environment setting information required for connection to a relay device 20 through Bluetooth and setting the first operating environment setting information to the portable terminal 10, a setting information generating unit 4 for generating second operating environment setting information required for connection to a telephone call control server 400 through a wireless LAN to make a call, a second terminal side operating environment setting unit 5 for setting the second operating environment setting information thus generated to the portable terminal 10, and transmitting the second operating environment setting information to the telephone call control server 400 and registering the second operating environment setting information therein, a setting information transmitting unit 6 for transmitting the second operating environment setting information to the relay device 20, and a second relay side operating environment setting unit 24 for setting the second operating environment setting information to the relay device 20, and transmitting the second operating environment setting information to the telephone call control server 400 and registering the second operating environment setting information therein, and a code is simply read by the portable terminal 10 to automatically perform setting required for utilizing the portable terminal 10 as a cordless extension unit of a cordless telephone.
