Wireless Data Acquisition Technology
NI Wi-Fi data acquisition (DAQ) devices combine IEEE 802.11g wireless or Ethernet communication, direct sensor connectivity, and the flexibility of NI LabVIEW software for remote monitoring of electrical, physical, mechanical, and acoustical signals. With built-in signal conditioning and the highest commercially available network security, Wi-Fi DAQ devices stream data in real time for easy to use, high-performance remote measurements.
Incorporating Wireless Measurements with Wired Data Acquisition Systems:
Wireless technology provides promising possibilities and benefits – reduced cost of cabling; measurements previously prohibited by physical location; distributed measurements; and intelligent, self-healing networks. Wireless is poised to play a significant role in shaping the capabilities of future measurement systems. But exactly what role and how? Will wireless replace wired systems? Will existing investments still be useful in future systems? What important decisions should be made before selecting a wireless data acquisition device? When should wireless not be considered as a possible solution?
There are many questions that need to be answered and there is still time to contemplate the possibilities before your existing measurement systems run the risk of technology obsolescence. This article helps to answer some of these questions by considering several high-level design decisions of wireless measurement systems and how to complement existing wired systems with wireless technologies.
From continuous monitoring of vibrations on mechanical systems to producing clean energy for domestic and industrial hot water, NI hardware and software tools can help you build customizable systems to meet your monitoring needs. Wi-Fi DAQ improves performance of your industrial remote monitoring application by:
Reducing cabling installation and maintenance cost
Providing secure, reliable data with 128-bit AES encryption
Integrating seamlessly with existing wired systems and enterprise (SCADA)
Leveraging widespread Wi-Fi infrastructure with standardized 802.11g protocol

Wireless Industrial Remote Monitoring
Industrial monitoring involves monitoring and controlling different plant, factory, or manufacturing conditions while logging data to enterprise systems. Production competitiveness constantly pushes the speeds of this equipment, and lately, there has been an ever-increasing emphasis on machine and automation efficiency, as well as performance and quality control. Wireless technology is can help you improve your processes by adding new measurements to your systems that were previously impossible or impractical with a cabled solution. Explore the following resources to learn how NI wireless hardware and software can simplify and improve industrial remote monitoring systems.
Network Monitoring System
The term network monitoring describes the use of a system that constantly monitors a computer network for slow or failing components and that notifies the network administrator in case of outages via email, pager or other alarms. It is a subset of the functions involved in network management.
While an intrusion detection system monitors a network for threats from the outside, a network monitoring system monitors the network for problems caused by overloaded and/or crashed servers, network connections or other devices.
For example, to determine the status of a webserver, monitoring software may periodically send an HTTP request to fetch a page; for email servers, a test message might be sent through SMTP and retrieved by IMAP or POP3.
Commonly measured metrics are response time and availability (or uptime), although both consistency and reliability metrics are starting to gain popularity. The widespread addition of wan optimization devices is having an adverse effect on most network monitoring tools -- especially when it comes to measuring accurate end to end response time because they limit round trip visibility.[1]
Status request failures, such as when a connection cannot be established, it times-out, or the document or message cannot be retrieved, usually produce an action from the monitoring system. These actions vary: an alarm may be sent out to the resident (SMS, email,...) sysadmin, automatic failover systems may be activated to remove the troubled server from duty until it can be repaired, etcetera.
Monitoring the performance of a network uplink is also known as network traffic measurement, and more software is listed there

Simple Network Manegement Protocol (SNMP)
The Simple Network Management Protocol (SNMP) is an application layer protocol that facilitates the exchange of management information between network devices. It is part of the Transmission Control Protocol/Internet Protocol (TCP/IP) protocol suite. SNMP enables network administrators to manage network performance, find and solve network problems, and plan for network growth.
Two versions of SNMP exist: SNMP version 1 (SNMPv1) and SNMP version 2 (SNMPv2). Both versions have a number of features in common, but SNMPv2 offers enhancements, such as additional protocol operations. Standardization of yet another version of SNMP—SNMP Version 3 (SNMPv3)—is pending. This chapter provides descriptions of the SNMPv1 and SNMPv2 protocol operations. Figure 56-1 illustrates a basic network managed by SNMP.

Remote Monitoring
Remote Monitoring (RMON) is a standard monitoring specification that enables various network monitors and console systems to exchange network-monitoring data. RMON provides network administrators with more freedom in selecting network-monitoring probes and consoles with features that meet their particular networking needs. This chapter provides a brief overview of the RMON specification, focusing on RMON groups.
The RMON specification defines a set of statistics and functions that can be exchanged between RMON-compliant console managers and network probes. As such, RMON provides network administrators with comprehensive network-fault diagnosis, planning, and performance-tuning information.
RMON was defined by the user community with the help of the Internet Engineering Task Force (IETF). It became a proposed standard in 1992 as RFC 1271 (for Ethernet). RMON then became a draft standard in 1995 as RFC 1757, effectively obsoleting RFC 1271.
Figure 55-1 illustrates an RMON probe capable of monitoring an Ethernet segment and transmitting statistical information back to an RMON-compliant console.
