Why is deep packet inspection (DPI) essential for wireless networks?

Mobile broadband adoption is inherently capacity-limited because of a finite wireless spectrum. While spectral efficiency is improving, capacity gains are tiny in comparison to the current and projected massive data traffic growth. Effective traffic management in mobile broadband networks is essential--DPI holds the key.
