Integrated microwave antennas and radios are used to transfer data in mobile transport networks. It’s a cost-efficient solution for fiber cable. The radio data is transmitted in a microwave hop. Simplified, a hop consists of two antennas including radios mounted in a tower on two different locations wirelessly communicating with each other.
It’s essential for the microwave hop that RF and water leakage are prevented since it causes disturbances. RF leakage causes signal/data loss and RF interference while water leakage can possibly short circuit the radio. Any disturbances are costly for Ericsson, the operators and the end customers and could be devastating if the hop is down. Therefore, this Master Thesis will focus on the interface between the radio and the microwave antenna.
Today’s radios and antennas have a single waveguide port and it’s essential that the waveguide ports can repeatedly be properly aligned against each other using a robust interface to fulfil requirements on environmental sealing, RF leakage etc. It’s also important to consider the fact that the radio interface is assembled on site by installers who have varied knowledge and experience. Lastly, you need to consider cost and modularity.
We would like to see continuous prototypes/mockups of different concepts during the project. These can be printed in one of our 3D printers we have inhouse or ordered from one of our suppliers when there is a need for a machined prototype.
As an outcome of the Master Thesis, we expect a concept of the interface design of the radio and the antenna. Preferably it is shown both in forms of CAD-files and drawings together with a prototype that demonstrates the concept.
In addition, we also would like you to propose a set of verification methods that we can use during design verification of this interface to see that it works as intended both during the design phase but also during volume production.
