Who invented WiFi and how does it work?
WiFi, also known as wireless fidelity, was invented by John O’Sullivan and his team in 1992 while working for the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Australia. They developed a method for transmitting data wirelessly using radio waves, which paved the way for the creation of WiFi technology. WiFi works by transmitting data through radio waves at a specific frequency, typically 2.4 gigahertz (GHz) or 5 GHz. This data is transmitted between devices, such as computers, smartphones, and routers, allowing them to communicate with each other without the need for physical cables.
The WiFi technology uses a protocol called IEEE 802.11 to manage the transmission of data between devices. This protocol ensures that data is transmitted efficiently and reliably, even in the presence of interference from other devices. WiFi routers, which are typically connected to a physical internet connection, transmit data to devices within range, allowing them to access the internet and communicate with other devices on the network. The WiFi signal is received by devices equipped with WiFi adapters, which decode the signal and allow the device to access the internet and communicate with other devices.
Is WiFi a proprietary technology, and who owns the patents?
WiFi is not a proprietary technology, but rather an open standard that is maintained by the Institute of Electrical and Electronics Engineers (IEEE). The IEEE 802.11 protocol, which is the basis for WiFi technology, is an open standard that is available for anyone to use and implement. However, the patents for WiFi technology are owned by various companies, including the Commonwealth Scientific and Industrial Research Organisation (CSIRO), which holds a significant number of patents related to WiFi.
The CSIRO has licensed its WiFi patents to many companies, allowing them to use the technology in their products. Other companies, such as Intel and Cisco, also hold patents related to WiFi technology. However, the open nature of the WiFi standard means that anyone can implement the technology without needing to obtain a license from a specific company. This has helped to drive the widespread adoption of WiFi technology and has enabled the creation of a wide range of WiFi-enabled devices.
How is WiFi regulated, and what are the rules governing its use?
WiFi is regulated by various government agencies and organizations around the world. In the United States, the Federal Communications Commission (FCC) is responsible for regulating WiFi and other forms of wireless communication. The FCC sets rules governing the use of WiFi, including the frequencies that can be used and the power levels at which devices can transmit.
The FCC also requires device manufacturers to obtain certification for their WiFi devices before they can be sold in the United States. This certification ensures that devices meet certain standards for safety and performance. Other countries have similar regulatory agencies that govern the use of WiFi. In addition to government regulations, WiFi is also governed by industry standards, such as those set by the IEEE and the WiFi Alliance. These standards ensure that WiFi devices from different manufacturers can interoperate and provide a consistent user experience.
