Abstract: This document discloses a solution for synchronizing two apparatuses of the same or different wireless network. A synchronization control apparatus may receive measurement reports from a first apparatus and a second apparatus, wherein at least one of the measurement reports comprises at least one information element indicating an offset between clocks of the first apparatus and the second apparatus. The synchronization control apparatus may synchronize the first apparatus and the second apparatus with each other on the basis of the measurement reports.

Abstract: A manhole (40) for desert environments where temperatures can be very high and environmental conditions such as erosion exert different challenges on sewage infrastructure, the manhole including a steel pipe telescope (450) matched to two circular heat resistant sealing rings (460, 461) in a concrete cone (400). The concrete cone is attached to a concrete manhole (410) with a heat resistant seal (462). The position of the concrete cone is stabilised by a large concrete slab (470) at the bottom of the manhole. The cover (430) of the manhole rests on the steel pipe telescope (450), and when the ground level changes, the steel pipe telescope can simply be repositioned within the concrete cone to match the changed ground level. All concrete parts (400, 410, 470) can be casted on-site, which means that preferably both the construction and the maintenance of the manhole happen at the installation site.

Abstract: This document presents a method for processing radio measurement reports in a location tracking apparatus, the method comprising: acquiring a plurality of radio measurement reports related to transmission of reference signals between a mobile tag being location-tracked and at least one location tracking node having a fixed location within a location tracking area, wherein each radio measurement report comprises a cycle index indicating a transmission cycle index of a reference signal associated with the radio measurement report and a radio measurement metric computed from said reference signal associated with the radio measurement report; combining radio measurement reports having the same transmission cycle index; and using the combined radio measurement reports in tracking the location of the mobile tag.

Abstract: This document presents a wireless location tracking system comprising a plurality of location tracking nodes to cover an area where the location tracking is to be carried out, wherein the location tracking nodes are configurable to form a static communication network infrastructure for routing communication messages; at least one mobile tag being location-tracked; and a control apparatus configured to receive through the communication network infrastructure a message associating said at least one mobile tag to at least one location tracking node and to map the location of the mobile tag on the basis of said association. The system further comprises at least one radio beacon node disposable to improve the coverage of the location tracking system.
