DPI Optimizes Mobile Applications

Mobile data provides a notable growth opportunity for cellular operators, but adoption will be slow unless networks can provide good service to all subscribers. Deep packet inspection enables operators to understand the applications their subscribers are using and to build appropriate networks.

The communication industry widely recognizes mobile broadband as the growth engine for wireless carriers. As cell-phone penetration reaches saturation and voice revenue plateaus, mobile-data revenue is one segment that continues to grow. Mobile data is available through 3G (third-generation) networks, which are increasingly exhibiting the strain of the increased traffic.

Most operators have announced plans to move to LTE (long-term-evolution) networks, which promise greater-than-100-Mbps data rates, a fivefold increase over 3G HSPA+ (high-speed-packet-access) networks. A quick look at customer-traffic patterns makes it clear that even network upgrades from 3G to LTE won’t deliver sufficient data rates to guarantee good service to all users. However, additional technologies such as DPI (deep packet inspection) can ensure that prioritized and managed traffic optimizes the user experience.
