Call for student participation! 

Do you test the performance of the newest devices in your research lab? Or your simulation tool enabled R&D for new modulator? Or maybe you are testing innovative optimisation algorithms with in-field data? Need to highlight your collaboration portfolio? Want more people to know of your group’s skills, tools and abilities? The TOP 2025 is the right place for it!

The TOP conference aims to strengthen the collaboration spirit in the UK telecom. For the special academia-industry showcase, we are open for proposals from students and early career researchers.
