LTE (Long-Term Evolution) technology promises higher data rates, better service quality, lower operational costs and more. The success of the early major LTE deployments is critical.

Operators involved in key large-scale LTE deployments rely on Spirent to ensure that devices are ready for the real world. Find out more.

The move from existing technologies to LTE represents the wireless world's most significant evolutionary step since the introduction of cellular services. New, complex modulation schemes, multi-antenna techniques and a new, all-IP flat network architecture are all being rolled out simultaneously. The resulting increase in complexity presents major challenges when configuring and validating the performance of LTE implementations.

Moreover, many operators plan to deploy LTE in newly available spectrum bands, such as 700 MHz in the US. While these bands are desirable in many ways, they also bring their own significant challenges and pitfalls which Spirent is working with leading operators to address in their test plans.

• Is your implementation optimized for the RF performance challenges of these new bands?

LTE deployments will add another radio access technology to existing UMTS or CDMA/EV-DO networks, requiring multi-mode devices that seamlessly interoperate between LTE and all supported legacy technologies.

• Have you verified that your implementation will seamlessly and transparently operate across multiple technologies?

Time to market, revenue potential and managing costs are paramount for establishing your success in LTE.

• Are you positioned to collapse the development/deployment timeline?

Can you verify that you have an implementation that will:

• Provide acceptable data throughput performance to users under real-world conditions?
• Enable devices to make correct system selections and work seamlessly across networks and between access technologies?
• Provide the required network capacity, performance and scalability?

As a pioneer in wireless, Ethernet and IP testing, Spirent offers best-in-class solutions to test performance and scalability of multi-technology LTE networks, devices and services under real-world conditions. Spirent's new partnership with AT4 wireless enables both performance testing and standards-based conformance/certification testing of LTE devices on the same Spirent platform.
