Wi-Fi is a technology for wireless local area networking with devices based on the IEEE 802.11 standards. Wi-Fi is CSIRO's Wireless Innovation by WLAN Project Team members[Mr Graham Daniels, Dr John O'Sullivan, Dr Terry Percival, Mr Diet Ostry, Mr John Deane]. The network’s central point is the access point, which is a router with transmitting antennas which route the transfer of data and provides Internet access and Internetworking to all devices connected to them, wirelessly.
Wi-Fi networks typically operates in unlicensed 2.4 and 5 GHz radio bands. Data is transferred over radio frequencies, allowing Wi-Fi capable devices to receive and transmit data when they are in range of a Wi-Fi network. Typically, the range of this Wi-Fi access point to any Wi-Fi capable devices is about 300 feet outdoors and 150 feet indoors.
Role of IEEE and Wi-Fi Alliance in Wi-Fi Technology?
IEEE 802.11 is the Working Group of Institute of Electrical and Electronics Engineers (IEEE) that deals with Local Area Networks (LANs), and its main role is to develop technical specifications for WLAN implementation.
The Wi-Fi Alliance is formed to ensure interoperability testing and certification for the rapidly-emerging 802.11 world. This gives consumers the certainty that they don’t need to worry about what company manufactured their devices, as long as they are Wi-Fi certified. It developed Wi-Fi Protected Access (WPA) in response to the compromise of 802.11’s WEP security.
It acquired Wireless Gigabit Alliance (WiGig) to promote 60 GHz.
What is the difference between WiFi and WLAN?
WLAN(Wireless Local Area Network) is a LAN to while a user (Station) can connect through a wireless connection. However, Wi-Fi is a type of WLAN that adheres to IEEE 802.11x specifications.
What are all the current challenges and Spectrum issues in Wi-Fi? Wi-Fi as a Technology used in IoT
A wide variety of other Wi-Fi developments are currently seeing significant activity across a very broad frontier of applications and markets. There’s significant evidence that Wi-Fi will in fact dominate the IoT market over time. Many Wi-Fi implementations have the power, form factor, component cost, and related physical and electronic characteristics to enable Wi-Fi to find a home in essentially any IoT application, broadband or otherwise.
And, most importantly, Wi-Fi-based IoT clients can leverage existing and common if not ubiquitous infrastructure, dramatically reducing cost-to-solution. Many IoT applications will likely find a home in the 900-MHz bands that originally hosted early WLANs, and now the domain of 802.11ah.
Dedicated Short-Range Communications (DSRC), which could become important particularly in vehicular applications like autonomous cars, is covered in 802.11p. Wi-Fi’s role in wireless and mobile applications is second to none, and there is no replacement technology on the horizon.
