Easy Mountable Wireless Data Communication Unit and a Sys- tem Comprising It
The present invention relates to a wireless data communication unit comprising a communication module configured to communicate wire- lessly and one or more permanent magnets arranged in a manner that enables the unit to be mounted on a magnetizable surface by means of the one or more permanent magnets, wherein the unit is a self-con- tained unit formed as a closed housing that is not connected to external power, communication or antenna using cables or wires.
Prior art
The next generation of measurement and control systems are operated using small wireless sensors and actuators. This development is known as the Internet of Things (IoT).
The many new units enable better control of operation and thereby sig- nificant improvements on our environmental and climate impacts.
The IoT solutions have been installed with remarkable success in build- ings and production but are still in the very early stages in underground systems. Such systems include grids for power, water, district heating, road surfaces, and city level earthquake monitoring. The reason these types of solutions lack behind is the difficulties of getting reliable internet connectivity for them, as they are mounted underground or very close to the surface of the ground, where internet connectivity is poor.
To circumvent the problem of poor internet connectivity, better coverage is needed. An efficient method to improve connectivity is installation of range extender cells, which add wireless access points to the network which repeat the signals.
The state-of-the-art solution to add range extenders to a network make use of cells which are costly and difficult to install, because they need
2 DK 2023 00224 A1 external supply in form of power, data cables, antenna, and the installer need access to the position where the cell is installed.
These limitations are major obstacles to the spread of IoT solutions.

The unit 2 comprises a battery 21 and a communication unit 26 that may comprise an integrated antenna. The communication unit 26 is at- tached to the processing unit 34. The unit 2 comprises a first perma- nent magnet 8 protruding from the housing 30. Likewise, the unit 2 comprises a second permanent magnet 8’ protruding from the housing 30. The permanent magnets 8 protrude from the housing 30 to such an extent that permanent magnets 8 can be passivated by means of one or more electromagnets 18, 18’ of the installation device 46 shown in Fig 13D when the unit 2 is being mounted on the magnetizable sur- face 48.
Fig. 13B illustrates the magnet field lines 28 of a permanent magnet 8 of the unit 2 shown in Fig. 13A.

Fig. 13C illustrates the magnet field lines 28’ of an electromagnet 18 of the installation device 46 shown in Fig. 13D. The magnet field lines 28’ of the electromagnet 18 cancel out the magnet field lines 28 of the permanent magnet 8 shown in Fig. 13B due to the superposition prin- ciple.
Fig. 13D illustrates a kit 52 according to the invention. The kit 52 com- prising a unit 2 corresponding to the one shown in and explained with reference to Fig. 13A and an installation device 46 comprising several more electromagnets 18, 18’ arranged in such a manner that each of the electromagnets 18, 18’ can be moved in a position, in which the electromagnets 18, 18’ can passivate the permanent magnets 8 of the unit 2 when the unit 2 is being mounted on the magnetizable surface 48.
The electromagnets 18, 18’ are arranged and configured to cancel out the magnet field of the permanent magnets 8. Accordingly, when the unit 2 and the installation device 46 are arranged as shown in Fig. 13D, the first electromagnet 18 and a second electromagnet 18’ gener- ate magnetic fields that cancel out the magnet field of the permanent magnets 8. Accordingly, the unit 2 can be moved into the desired posi- tion and be attach to the magnetizable surface 48 (by deactivating or moving the electromagnets 18, 18”).
It can be seen that the electromagnets 18, 18' enclose part of the per- manent magnets 8 while a gap 50 is provided between the installation device 46 and the magnetizable surface 48. This is achieved by apply- ing an installation device 46 having a width that is smaller than the width with which the permanent magnets 8 protrude from the housing 30.
The installation device 46 may be integrated in the stick shown in and explain with reference to Fig. 7.
