Alcatel-Lucent 9900 WirelessNetworkGuardian

Wireless service providers around the globe are beginning to experience significant subscriber uptake of their wireless data and broadband services. This growth is driven in large part by the growing popularity of IP-enabled cell phones, laptop aircards, and new data pricing plans that make wireless data access affordable by the consumer market.

This uptake in services increases service provider revenue, however, Alcatel-Lucent and service providers worldwide understand transmitting IP packet data and IP applications places many different types of load on wireless networks, and are evolving the design and operation of wireless networks to efficiently and optimally accommodate these loads.

To illustrate, Figure 1a depicts the normalized bandwidth consumed by applications running on a commercial wireless network. By comparison, Figure 1b depicts the same applications on the same day relative to the cellular airtime consumed in the network to support these loads.

Today’smonitoring and packet inspection products allow wireless service providers to monitor subscriber and application usage behavior on their network (Figure 1a)

—but they don’t translate this into wireless resources (Figure 1b).

The Alcatel-Lucent 9900 Wireless Network Guardian enables a paradigm shift in network operation and management for wireless operators. It allows wireless service providers to associate individual subscriber behavior to resource consumption at every layer and element in a wireless data path in real time (Figure 2).
