Dynamic BTS / UE Designs with 89600 Software
应用文章
For system-integration engineers and verification engineers, troubleshooting new BTS and UE designs will only get tougher as wireless standards become more advanced. Within standards such as LTE, the biggest challenges stem from the complex interactions between the physical (PHY) and media access control (MAC) layers during signaling operations.
Those who typically work at the PHY layer tend to rely on two tools of choice: signal analyzers such as the Keysight Technologies, Inc. PXA (N9030A) and vector signal analysis software such as the Keysight 89600 VSA. As a complement to the 89600 VSA, Keysight has created the 89600 wireless link analysis (WLA) software.
Wireless link analysis correlates control messages with the wireless links they manage, giving PHY-savvy engineers greater visibility into the autonomous MAC-layer messaging that occurs between devices. In both system integration and verification the ultimate benefit is a deeper level of insight that accelerates day-to-day troubleshooting and ultimately improves time to market.
This application note provides a brief look at four key topics: link operation, wireless link analysis, a graphical approach to WLA, and dynamic measurements. It also presents an overview of additional capabilities specific to the analysis of LTE devices.
