Solutions for Manufacturing Next-Generation Wireless Devices
애플리케이션 노트
From the early days of cellular handset shipments, signaling test has been used to address interoperability problems during cellular device production. In today’s highly competitive marketplace, more wireless bands and multiple technologies (e.g., LTE, HSPA+, GSM/EDGE, W-CDMA, cdma2000®, 1xEV-DO, Bluetooth®, and WiMAXTM) are being implemented in smart phones and other mobile devices. Therein lies the dilemma. Adding more formats with existing signaling test methods, increases test time and, in turn, cost. But, manufacturers under competitive pressure have to find ways to reduce the cost-of-test in order to improve their profit margins.
Non-signaling offers one solution to this dilemma. Non-signaling is commonly used to describe the next-generation test techniques continuing to develop within the cellular industry. Non-signaling test techniques decrease cost-of-test, per device, by removing over-the-air (OTA) signaling test time overhead and test equipment cost, during mobile device production.
