Packet Microwave graduation project help

Hello ,

I am currently pursuing a MS degree in Telecommunications Engineering I am looking for a good topic for my graduation project which I hope that it has a future scope . Therefore I searched a topic related to the new technologies in Telecommunications field especially 4G. I found that " Packet Microwave " will be a good idea but I don't know if I can do something creative with it . I don't want to just write a report about theory and how it works. I want to be more creative. So I would be very grateful for some help on what can I work on ?!
Many Thanks in advance .
