Full-Duplex Radio Integrated Circuit Could Double Radio Frequency Data Capacity

Zothecula writes Full-duplex radio communication usually involves transmitters and receivers operating at different frequencies. Simultaneous transmission and reception on the same frequency is the Holy Grail for researchers, but has proved difficult to achieve. Those that have been built have proven complex and bulky, but to be commercially useful in the ever-shrinking world of communications technology, miniaturization is key. To this end, engineers at Columbia University (CU) claim to have created a world-first, full-duplex radio transceiver, all on one miniature integrated circuit.

One question:

Why? Is the spectrum that crowded that we need this? Making this work in the real-world will not be a piece of cake...

The parts of the spectrum that have bandwidth enough for most of today's applications AND good signal propagation characteristics certainly are.
