Long Term Evolution (LTE) – Network Diagnostics and Monitoring Solutions

With the massive increase in mobile data traffic, and as networks continue to converge towards all-IP infrastructures, many operators are considering LTE, or Long Term Evolution, a new network technology first defined in 3GPP release 8 which promises to be an all-IP network infrastructure that will dramatically decrease the cost of delivering high-value multimedia services and applications.

Given the advantages, LTE also introduces some unique challenges for network operators that must be overcome in order to profitably deliver high quality services and applications. Coming from a 2G/3G environment, operators have come to understand what specific network parameters impact their network and services. In the all-IP LTE environment, network behavior is less understood and requires new tools and techniques optimized for an IP environment.

Interoperability is also a major issue since most operators deploying LTE will be doing so alongside their existing 2G/3G legacy networks, and in some cases, alongside 4G technologies such as WiMAX.No doubt – when it comes to LTE, operators will need to adopt a strategy that takes into account the necessary flexibility and breadth of technologies required to profitably manage, optimize and troubleshoot their networks and services.
