The expansion of 4G is moving rapidly, as is the development of 5G. Globally, it is estimated that 4.5 billion people have mobile phones and that the number is expected to exceed 5 billion by 2019. Prominent research as part of international collaborations is being conducted at LiU that is contributing greatly to this development, as well as to the development of the internet of things.

According to the forecasts, in a few years' time, more than 50 billion gadgets will be connected to the internet – the internet of things. Leading research is being conducted into, for example, modular solutions for sensor networks. For instance, there are applications related to healthcare, smart cities and energy efficiency.

The research group in mobile telecommunications is conducting research concerning smart networks – the performance of wireless networks, the allocation of radio resources, traffic routing and measurements of bandwidth, quality and mobility. 

At the Division of Communication Systems there is research within signal processing and coding for multiple-antenna systems, known as Massive MIMO, as well as resource allocation in wireless networks. 

A research group at the Division of Integrated Circuits and Systems is developing fast broadband circuits and the hardware that, for example, makes antennas interact. Research is also being conducted concerning wireless transmission from the body's own network to its surroundings, known as body-coupled communication (BCC).

A fourth area is found at the Division of Communications Electronics which conducts research concerning and develops modular solutions for wireless sensor networks – for high speeds at a low cost, with applications such as in smart cities or the measurement of moisture in buildings of historical interest.
