WiFi? Why not!?
Despite its image as a consumer-level technology, WiFi is actually an ideal basis for an effective, low-cost mobile data network with wide area coverage. When used correctly, WiFi is a perfect fit for many applications that need highly mobile network access, including automated warehousing and public transportation. Compared to competing technologies, such as cellular, Bluetooth, Zigbee, and proprietary radio networks, WiFi offers numerous advantages, including:
· Lower implementation costs
· Close-to-zero operating cost
· High bandwidth
· Usable range
· Proven security
· Great future upgrade and expansion potential · Very wide support from manufacturers WiFi is also the best-understood wireless technology amongst engineering personnel and service staff—ensuring effective, lower-cost technical support.
However, WiFi’s origins as a consumer-oriented technology mean that wireless device manufacturers need to enhance some WiFi features to better handle industrial applications.
These include:
· Reducing access point handover delays to provide seamless roaming, · Hardening WiFi devices to avoid severe damage from natural and manmade sources such as lightning, static electricity (ESD), and power surges.
This white paper discusses how to best address these critical issues, as well as other important considerations that will help users realize the unique advantages of WiFi in a network with high mobility requirements—and as a key enabling technology for the Industrial Internet of Things (IIoT).
