Abstract: A system and method for determining a position or a movable device is disclosed. The present system utilizes a movable device equipped with a locator device that has an antenna array such that it may determine the angle of arrival of a plurality of incoming beacon signals. In certain embodiments, the movable device is also able to measure its distance travelled. By knowing its distance moved and the angle of arrival from each beacon, the locator device is able to calculate its position as well as the position of each beacon. This procedure may be executed at regular intervals so that the movable device accurately determines its position.

Abstract: The invention relates to a method for a communication system comprising a first device and a second device. The method comprises transferring a packet from a first device to a second device, which packet comprises an authentication request having a challenge; encrypting the challenge from the authentication request by the second device; including the determined challenge as a challenge-response to a response packet by the second device; sending the response packet from the second device to the first device; determining whether the challenge matches with the challenge-response, and if so, authenticating the second device.

Abstract: A method, an apparatus and a computer program product are used for device filtering. A packet is received from a device, after which it is determined whether the device is allowed to be responded to, wherein the determination comprises at least one of the following: determining a received signal strength indication from the packet; or determining a time from previous connection of the device; or determining the data in a payload of the packet.

Abstract: The application relates to a method, an apparatus and a computer program product. The method comprises adjusting dynamically a sensitivity of a receiver from a default sensitivity to a low sensitivity; wherein the adjusting is based on the signal strength of at least one existing connection or at least one previous connection; receiving only such packets by the receiver which are available with the low sensitivity.

Abstract: A method, an apparatus, a system and a computer program product are provided for Bluetooth low energy technology. The method may be carried out by a Bluetooth low energy module. The method may include: detecting an advertisement packet from an advertising device; extracting time information of the advertisement packet; generating a new time information on the basis of the extracted time information; and sending an advertisement packet at the new time information. A system may include a plurality of advertising devices that implement the method, with one of the advertising devices being a master advertiser, and the other advertising devices being slave advertisers.

Abstract: Disclosed herein are apparatus and methods capable in one example of transmitting a first advertisement packet indicating that an advertising device is scannable; receiving a scan request from at least one scanning device; determining, based on the received one or more scan requests, whether a corresponding one or more scanning device is an allowed for connection; transmitting a second advertisement packet indicating that said advertising device is connectable; and receiving connection requests from the allowed at least one scanning device.
