A network of modular, multitier pool mobile units, that wander around and under water of a swimming pool. The pool mobile units monitor for safety, emergency and accident related events and undertake appropriate actions to provide care and protection for swimmers, family members and bystanders. They scrub and clean the swimming pool bottom and wall surfaces and emit chemical agents to sanitize the swimming pool water. A central server provides safety monitoring help for drowning swimmers, and emergency and accident supports.

One apparatus for providing high-resolution CSI feedback includes a processor and a radio transceiver. The processor computes sets of amplitude and phase parameters for one or more channel compression matrices. Here, each channel compression matrix corresponds to one transmission layer of a multiple-layer transmission, where each channel compression matrix is comprised of one or more column vectors. The radio transceiver sends indications of the sets of amplitude and phase parameters to one or more network entities is a mobile communication network.

A green area maintenance system includes an autonomous mobile green area maintenance robot having a treatment tool and a cutting tool differing from the treatment tool. The robot and the cutting tool are configured to allow fixing of the cutting tool to the robot. The system includes a user control device, and has an autonomous operation mode and a cutting operation mode. In the autonomous operation mode the autonomous mobile green area maintenance robot with its treatment tool operates autonomously and the cutting tool is set out of operation, and in the cutting operation mode the cutting tool is fixed to the green area maintenance robot and operable. The robot with its treatment tool and cutting tool are controlled by a user via the user control device, and an operation mode switching device for switching between the autonomous operation mode and the cutting operation mode.
