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.
Why Is Deep Packet Inspection (DPI) Essential for Wireless Networks?
Mobile broadband is today's growth engine for wireless network operators. Even in the current economic downturn, wireless network operators continue adding new subscribers on their data plans. In fact, Verizon Wireless reported 41 percent growth in data revenue for Q4 2008, and while AT&T's overall profit was down 23 percent in Q4 2008.
