LitePoint announces IQcell, a multi-device user experience test solution for LTE cellular products

LitePoint, vendor of wireless test solutions, announced Tuesday the LitePoint IQcell multi-device cellular signaling test solution which enables user experience testing of LTE cellular devices.

IQcell provides a fast, efficient method to pinpoint the root cause of failures reported by a user so device repair service centers can use IQcell and IQservice software to perform RF parametric testing on phones returned by customers. This enables device makers and carriers to repair faulty phones and reduce the cost of replacing easily repaired phones with new ones.

Currently available, the IQcell is designed for mobile device original equipment manufacturers (OEMs) to test performance of popular device uses such as mobile hotspot functionality, voice-over-LTE (VoLTE) calling, internet browsing and streaming videos.

Testing for each of these applications is done via an over-the-air connection that mimics true user experience scenarios. User experience is critical for testing complex devices, and ensures that the device will work in customer hands as designed, under everyday usage.

Available in 2-port and 8-port configurations, IQcell supports LTE-FDD, LTE-TDD, WCDMA/HSPA and GSM. The IQcell 2-port configuration enables rapid diagnostic of IoT device cellular radio quality and the automated test system detects the cellular radio capability by running a pre-defined set of test cases.

The IQcell 8-port configuration increases test capacity with up to four devices running concurrently on four separate cells and each cell has a dedicated measurement system for high speed, high accuracy, technology specific parametric measurements.

The IQcell 8-port configuration provides the capability of simultaneously running 2×2 MIMO throughput testing on all 4 DUTs. The integrated iPerf server enables single-input single-output (SISO) or multiple-input multiple-output (MIMO) throughput testing. IQcell supports the testing of Voice-Over-LTE, giving a user high confidence in the device’s performance under real live network scenarios. The test cases include Mobile-Originated (MO)/Mobile-Terminated (MT) calls with audio loopback, and Mobile-to-Mobile voice calls.

Optimal Space Efficiency

Signaling testers are typically designed for lab environments, where space is not a major concern. Conversely, space is often limited on the factory floor. By packing four cellular testers into one compact 2U rack-height design, IQcell offers the most space-efficient tester on the market.

“User experience is key to a device’s success and the IQcell helps OEMs and service centers see what a user sees instead of trying to translate some parametric measurements into a user’s actual experience with the product,” said Adam Smith, director of product marketing at LitePoint. “We are constantly seeking to improve the testing experience making it faster and less expensive so that more devices can be cost effectively tested. With IQcell, we’ve reduced the time and cost of test so that device makers don’t have to risk product quality because they can quickly and efficiently complete a variety of signaling tests on multiple devices simultaneously.”
