    Abstract: This document describes a solution for sensing a location by using a wireless network. According to an aspect, a method for an access node of the wireless network comprises: receiving, by the access node from a wireless device at a location, a channel measurement signal; determining, by the access node, precoding coefficients for the location based on the channel measurement signal; storing, by the access node, the precoding coefficients as linked to the location; and utilizing, by the access node, the precoding coefficients to acquire information on the location.

    Abstract: A method, apparatus and computer program product are provided for displaying messages by reducing a reflectivity of a display. A display, such as a smart mirror, provides reflective properties and digital information. The reflectivity of some portions of the display may be altered such that the display provides the visual effect of steam. By varying the reflectivity in different portions of the display, messages may be provided via the display so as to appear written in the steam. Trigger actions, such as a user entering the vicinity, the detected sound of miming water, and/or the like, may cause the visual effect of steam or display of the message. A user may provide a message by a hand gesture, or writing the message in the air and see the message at is provided via a display. Users may transmit messages to other users, and may view received messages in the display.

    Abstract: This document discloses a solution where power management of devices of a wireless networks are controlled in connection with an absence period. According to an aspect, an apparatus determines at least one allowable power management mode for at least a second apparatus; causes transmission of a first frame indicating the at least one allowable power management mode; and causes transmission of an indication of an absence period during which it is not possible to transfer frames with the apparatus, wherein the indication is provided in at least one of the first frame and a second frame. The first frame configures at least the second apparatus to be ready to communicate with the apparatus at the end of the absence period in a case where the at least one allowable power management mode indicates a first power management mode.

    Abstract: Apparatuses may stay synchronized with a network via a beacon signal that is transmitted at a set interval. Various communication-related activities may be planned around an instance when a beacon signal is expected, or a target beacon transmission time (TBTT). While some networked apparatuses are active during every TBTT, other apparatuses may operate using a diluted beacon period that is an integer multiple of the network beacon signal interval. Diluted beacon intervals may initiate periods of time during which apparatuses may become “aware” of other apparatuses. Awareness may comprise information related to communication configuration, apparatus status, and services offered by the various apparatuses in the network. Awareness information obtained during an awake window may also comprise information on data-related tasks that are pending in one or more apparatuses which may allow for the control of further data conveyance activities.

    Abstract translation: 设备可以通过经过设定间隔发送的信标信号与网络保持同步。 可以在期望信标信号的情况下或者目标信标发送时间（TBTT）的情况下规划各种通信相关的活动。 虽然一些网络设备在每个TBTT期间是活动的，但是其他设备可以使用作为网络信标信号间隔的整数倍的稀疏信标周期来操作。 稀释的信标间隔可以启动装置可能变得“意识到”其他装置的时间段。 意识可以包括与由网络中的各种装置提供的通信配置，设备状态和服务有关的信息。 在唤醒窗口期间获得的意识信息还可以包括关于在一个或多个设备中待处理的数据相关任务的信息，这些设备可能允许进一步控制数据传送活动。

    Abstract: There is provided, for example, a method, comprising: transmitting, by a wireless device, a data accumulation request to an access node of a wireless network, wherein the data accumulation request comprises at least one downlink accumulation rule for accumulating downlink data; receiving a message from the access node, wherein the message indicates that there is downlink data in the access node for the wireless device; and triggering a service period for receiving the downlink data from the access node upon determining, on the basis of the received message, that the downlink data satisfies the at least one downlink accumulation rule.
