A terminal for use within an unknown regulatory domain, and a computer program product and method for configuring the terminal, are provided. The terminal can comprise first program instructions to actively scan one or more domain independent channels in a frequency band, second program instructions to configure the terminal for use in the unknown regulatory domain in response to the terminal receiving regulatory domain information as a result of actively scanning one or more of the domain independent channels, third program instructions to passively scan one or more domain dependent channels in the frequency band in response to the terminal not receiving the regulatory domain information as a result of actively scanning one or more of the domain independent channels, and fourth program instructions to configure the terminal for use in the unknown regulatory domain in response to passively scanning one or more domain dependent channels in the frequency band.

Terminal configurable for use within an unknown regulatory domain

The present disclosure describes a methodology for wireless power transmission based on pocket-forming. This methodology may include one transmitter and at least one or more receivers, being the transmitter the source of energy and the receiver the device that is desired to charge or power. The transmitter may identify and locate the device to which the receiver is connected and thereafter aim pockets of energy to the device in order to power it. Pockets of energy may be generated through constructive and destructive interferences, which may create null-spaces and spots of pockets of energy ranged into one or more radii from transmitter. Such feature may enable wireless power transmission through a selective range, which may limit operation area of electronic devices and/or may avoid formation of pockets of energy near and/or over certain areas, objects and people.

Wireless power transmission with selective range

Configurations and methods of wireless power transmission for charging or powering one or more electronic devices inside a vehicle are disclosed. A transmitter capable of single or multiple pocket-forming may be connected to a car lighter, where this transmitter may include a circuitry module and an antenna array integrated within the transmitter, or operatively connected through a cable. This cable may allow the positioning of the antenna array in different locations inside the vehicle suitable for directing RF waves or pockets of energy towards one or more electronic devices. Transmitter's configuration can be accessed by one or more electronic devices through Bluetooth communication in order to set up charging or powering priorities.

The present disclosure describes a methodology for wireless power transmission based on multiple pocket-forming. This methodology may include one transmitter and two or more receivers, being the transmitter the source of energy and the receivers the devices that are desired to charge or power. Both devices, the transmitter and receiver, may communicate to each other via a wireless protocol. By communicating to each other, the transmitter may identify and locate the devices to which the receivers are connected and thereafter aim pockets of energy to each device in order to power them.

Methodology for multiple pocket-forming

The present disclosure describes a methodology for wireless power transmission based on pocket-forming. The method includes a transmitter device capable of forming pockets of energy used by a receiver device to charge an electronic device such as a computers, cell phones, tablet and/or devices of the like. The method may include using an array of antennas at the transmitter to locate the position of a receiver device. The transmitter may identify the position of the device by capturing a signal from a receiving device using two subsets from the array of antennas. The subset of antennas may then be adjusted to form pockets of energy at the appropriate location of the receiving device. Previously stored data pertaining to each antenna in the array may serve to determine the proper adjustments for the entire array of antennas based on the results from the subsets used to capture the receivers signal.

Method for 3 dimensional pocket-forming

An antenna is provided with an electronic component or circuit that has a value corresponding to properties of the antenna. A read mechanism reads the value and sets an operational status of a transceiver based on the value. In one embodiment, electronic component is a resistor having a value that identifies the antenna properties. A table may be used to correlate resistor values to different types of antennas or sets of antenna properties. Alternatively, the circuit can be embodied in a microchip that provides a response to a challenge sent by the read mechanism. The response encodes the properties of the antenna. The encoding scheme includes values from the challenge. Alternatively, the response is a code that is indexed into a table of antenna properties. In one embodiment, the antenna is connectorized.

Various regulatory domains promulgate standards to define how wireless devices should operate in certain frequency bands The 5 GHz spectrum is of particular importance to certain regulatory domains because of radar systems also operating in this spectrum To avoid interference with such radar systems, wireless devices operating in this spectrum should be able to detect radar and quickly vacate any channels currently used by the radar systems In a channel switching technique, if the new channel is radar-exempt, then normal operation commences on the new channel If the new channel is non-radar-exempt, then normal operation commences on a temporary radar-exempt channel and an aggregate background scan can be performed on the new channel If no radars are detected using the aggregate background scan, then operation is switched from the temporary radar-exempt channel to the new channel This channel switching technique minimizes disruption to users during a radar event

Various regulatory domains promulgate standards to define how wireless devices should operate in certain frequency bands. The 5 GHz spectrum is of particular importance to certain regulatory domains because of radar systems also operating in this spectrum. To avoid interference with such radar systems, wireless devices operating in this spectrum should be able to detect radar and quickly vacate any channels currently used by the radar systems. Techniques are provided for performing startup scans for radar, identifying backup channels for a possible channel switch, and efficiently changing channels in the event of radar detection in the operating channel. These techniques advantageously meet current regulatory standards governing DFS while minimizing network startup delays and disruption to users during a radar event.

Methods for implementing a dynamic frequency selection (DFS) feature for WLAN devices

A set of global location signals, an SBAS (Satellite Based Augmentation System), or an ACI (ambient country identifier) signal can be used to automatically provide location awareness for a WLAN device. If one of the set of global location signals, the SBAS signal, or the ACI signal is detected, then the WLAN device can configure itself to comply with channel and power settings for the country/region having the detected signal(s). After configuration, the WLAN device can be “locked” to the country/region having the signal(s), thereby ensuring legal operation of the WLAN device even after subsequent restarts. If one of the signals is not detected, then the WLAN device can be configured in a default mode, e.g. an “open mode” in which end users can configure the WLAN device by entering a country of operation or a “common mode” in which the channel and transmit power settings meet global spectrum usage requirements.
