Multicell simulation GUI Interface

Have been a long time wish, to make a completely configurable simulator for wireless system all phy layer tuning etc. I have been using itpp and g++ on linux for my simulator work see some description here (Personal blog). Later I added a frontend to manage the input configuration (screenshot  is here)

Now, recently I finished a tool/interface to display a multicell deployment scenario with macro, mobiles and pico/small cells. ( droping of base-stations and nodes, pathloss calculation was done by a friend). The screenshot is

The green dots are pico transmitters, Black are base-stations with directional antennas. Other nodes are receivers and the color shows the SIR of the node (Lowest : blue, Highest Orange). The front-end was developed using Qt library (Open source)
