Considering that COST2100 mainly deals with propagation and antenna, physical layer and radio network aspects and according to the structure of the previous COST Actions on mobile communications, COST2100 is organised in three Working Groups (WGs).

WGs might be organized in SubWorking Groups (SWGs) focused on specific topics. Moreover, the setup of Special Interest Groups (SIGs), dealing with cross layer issues and fostering interaction among different WGs, is expected.

The number of WGs will be fixed for the whole duration of the Action, whereas the number (and relevant topics) of SWGs and SIGs will be dinamically upgraded according to the interest of people involved in the Action.

So far, the following SWGs have been created:

Moreover, the following SIGs have been also created:
