The requirements include fast association, simple human-to-machine interfaces and low power. A PAN is defined as the network that surrounds a person or a smart device. The Bluetooth standard addressed the needs for a low power Personal Area Network (PAN). These drawbacks created a gap in the market and several standards have emerged to address the very low power wireless market.īluetooth and Zigbee were both introduced to address markets not serviced well by WiFi. The drawback is power consumption and processing power required to effectively manage the 802.11 stack.

As a result, 802.11n has the highest bandwidth of any short range wireless standard. The committee prioritises security and speed over all other tradeoffs. The committee managing this standard is aims to create the best possible wired TCP/IP network replacement. WiFi is short for Wireless Fidelity and is a standard used to identify WLAN devices. WiFi or IEEE 802.11a/b/g/n is the widest deployed consumer and enterprise wireless TCP/IP network solution. Given the number of wireless standards to choose from, the question becomes which standard is the right standard to deploy. Deploying a standardised radio solution today is a cost-effective secure way to both monitor and control devices in the field or factory. In addition, several new free-to-use frequency bands where introduced in the 80s including the 2.4GHz and 5GHz bands. The most recent standards are secure enough for broad deployment. Over the last twenty years, several standards have been developed to define robust radio solutions. The drawback of these solutions were a complete lack of security and limited bandwidth. Radios that supported these types of modulation could be created easily with a handful of discrete parts. The solutions used simple modulation techniques like amplitude-shift keying (ASK) or frequency-shift keying (FSK). In the past, these networks were typically sub 1GHz proprietary systems. Wireless networks have been used for over 30 years in the industrial market. Another important enabler for Industrial IoT is wireless standardisation. These advancements include reduced cost of data storage, lower power RF solutions and higher levels of network accessibility.

Multiple technology advancements have converged to make large-scale Industrial IoT deployments possible.
