Solutions For Femtocell Manufacturing Testing

Application Notes

Femtocells (3GPP Home Node B for W-CDMA/HSPA and enhanced Home Node B for LTE) are low-power wireless access points that connect standard mobile devices to a mobile operator’s network via residential DSL or cable broadband. While a compelling entrant into the broadband CPE (Consumer Premises Equipment) market dominated by Wireless LANs, femtocells are forcing manufacturers to confront a number of test considerations; namely cost, quality and volume. Early femtocells are costly (roughly $100-$300), multiformat (e.g., may require GPS, support for W-CDMA, LTE or WiMAX™, etc.), operate in the licensed spectrum, and face stringent conformance requirements. Achieving high volumes and driving down cost requires every aspect of the manufacturer’s design through production to be streamlined. The ultimate goal is to reduce test times while maintaining quality, a dificult task since some designs will be unstable at irst launch and require rigorous conformance testing and veriication of complex functionality (e.g., network sniffer mode, Rx sensitivity) and new formats. Addressing these constraints demands fast test equipment with just enough performance to enable rigorous veriication early in production and less testing as volumes increase.
