Wireless Data Acquisition Resource Kit

Wireless Data Acquisition NI Wi-Fi data acquisition (DAQ) devices combine IEEE 802.11b/g wireless or Ethernet communication, direct sensor connectivity, and the flexibility of NI-DAQmx software for remote monitoring of electrical, physical, mechanical, and acoustic signals. Use the following resources to learn how to extend your measurements to applications where wiring is difficult or cost-prohibitive.

• White Paper: Wi-Fi DAQ Under the Hood: Streaming Wireless Measurements
  To make wireless a viable technology for data acquisition, National Instruments has developed Wi-Fi DAQ streaming technology that is capable of reliable, continuous waveform acquisition over an IEEE 802.11 network. This paper provides an in-depth discussion of three key technologies that make NI Wi-Fi DAQ a reliable platform for wireless data acquisition.
• White Paper: Wi-Fi Security Primer for Data Acquisition
  IEEE 802.11 (Wi-Fi) network security has matured significantly in the IT space over the past 10 years, making it a viable solution for today’s wireless data acquisition applications. Because Wi-Fi uses air as its physical medium, it offers unique security challenges beyond those of a wired system. This primer offers an overview of industry-standard security techniques for data protection using NI Wi-Fi DAQ.
• Tutorial: Wireless Data Acquisition – Range versus Throughput
  Unlike a cabled or plug-in architecture, NI Wi-Fi DAQ transmits data as RF signals through the same space as every other wireless device, including laptops, smart phones, and cordless phones. Understanding how this affects the transmission range and throughput performance of a wireless data acquisition device is important when designing your application.
• Tutorial: Wi-Fi DAQ Battery Selection Guide
  Every wireless data acquisition application is different and so, too, are its power requirements. Sometimes battery power is the only option for an application; at other times, however, batteries may supplement an alternative power source or serve as a backup. This tutorial is a guide for selecting a battery for your NI Wi-Fi DAQ device when power is not readily available
• Webcast: Optimizing Wi-Fi Network Performance for Wireless Data Acquisition
  NI Wi-Fi DAQ devices use the IEEE 802.11b/g networking standard, providing industry-standard wireless connectivity, high bandwidth, and ease of use. However, not all IEEE 802.11 (Wi-Fi) networks are optimized for wireless data acquisition applications. View this webcast to learn how to optimize IEEE 802.11 networks for optimal NI Wi-Fi DAQ performance, including sampling rates (data throughput) and transmission range.
• Example Code: Synchronizing Multiple NI WLS/ENET-9xxx Devices
  The NI WLS-9163 C Series wireless carrier features a four-position trigger connector that features two digital lines (PFI0 and PFI1) and two ground pins. This example demonstrates how to synchronize two NI WLS-9215 wireless DAQ analog input devices using the PFI0 and PFI1 trigger pins of the WLS-9163 carrier.
• Case Study: Wirelessly Monitoring Construction Noise and Vibrations
  Using NI LabVIEW software, the NI Sound and Vibration Measurement Suite, and NI Wi-Fi DAQ hardware, SAPHIR developed the PC-based Surveillance of Acoustics and Vibration in the Environment (SAVE) system to wirelessly monitor acoustics and vibrations at construction sites.
