An earth positioning system (EPS) is provided. The EPS includes a plurality of fixed LED lights with communication functions and a mobile communications device. A cloud computer and at least one map marked with world coordinates of the fixed LED lights may be further included. The LED light includes a substrate, at least one LED die, a power supply, a wireless communication module, a control unit and a housing. The LED lights may be arranged in indoor and outdoor environments, with coordinates represented in longitude, latitude and altitude. The coordinates are included in a map data of the cloud computer. When the mobile communication device moves with its carrier, the world coordinates of the mobile communication device can be located based on the coordinates of the LED lights nearby or based on the unique IDs of the LED lights together with the aforementioned map.

A mobile robot includes a chassis, a shell moveably mounted on the chassis, and a cutting assembly mounted to the chassis. The mobile robot also includes a communication system that includes an antenna module disposed on a rear portion of the mobile robot. The antenna module includes a base assembly, and an antenna assembly mounted to the base assembly by a spring. The antenna assembly includes a ranging antenna, and at least three angle antennas arranged axisymmetrically about the ranging antenna, such that the ranging antenna and the three angle antennas define a tetrahedral geometry for determining an angle of arrival for one or more incident signals.

There is described an interior positioning system for tracking spatial position of communication devices within a remote location. The interior positioning system generally has: a radio frequency network distributed through said remote location; beacons spaced-apart from one another throughout said remote location and powered by said radio frequency network, each beacon locally emitting a corresponding beacon identifier which when received by a nearby communication device is communicated over said radio frequency network by said communication device; and a tracking controller being communicatively coupled to said radio frequency network, said tracking controller stored thereon tracking data associating each of said beacon identifiers to respective spatial coordinates, and instructions that when executed perform the steps of: receiving said beacon identifier communicated over said radio frequency network by said communication device, and determining spatial coordinates of said communication device by cross referencing said received beacon identifier to said tracking data.

A wireless network including user equipment (UE) and base stations is configured to perform position determination with low latency and synchronized to a common time within a wireless network. The UE and base stations are configured to perform positioning measurements at a specific time point or within a window around the time point in a measurement period. The time point may be relative to a timing event within the wireless network, such as the beginning or end of a positioning reference signal window or a specific message in a layer 1 or layer 2 transmission. A location server may be provided with the positioning measurements or a position estimate from the UE and provide the position estimate to an external client within the measurement period.

A detector base for fixing to a mounting surface may include a connection for connecting to a detector line of a hazard alarm system and a first connection side for releasably attaching a hazard detector embodied as a point detector. The first connection side may be electrically and structurally co-ordinated with a second connection side of such a hazard detector, such that the latter is releasably attachable to the detector base and is indirectly connectable via the latter to the detector line. The detector base may include a radio device affixed to the detector base and serving for transmitting position data of the detector base mounting location and/or for transmitting a reference to a database having said position data. The radio device may be based on a Bluetooth low energy standard.

The present disclosure relates to a transmission device and a transmission method, a reception device and a reception method, and a program that enable acquisition of accurate location information in an indoor environment. A reception device includes: an intra-body communication reception unit that receives location identification information from another device by a communication method using the human body as the communication medium, the location identification information being for identifying the location of the reception device; a location recognition unit that recognizes the current location of the reception device in accordance with the received location identification information; and a storage unit that stores the recognized current location. The present disclosure can be applied to transmission/reception devices and the like that perform communication by a communication method using the human body as the communication medium.
