Wi-Fi is fast becoming essential for the vast majority of people for both business and personal activities.
What is Wi-Fi?
Wi-Fi is actually a series/family of protocols that enable devices to communicate using wireless networks. It was (officially at least) invented in 1991 by a team working at the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Australia
Where is it found?
Wi-Fi is used domestically, commercially and in industrial spaces, as well as in public spaces and buildings.
How does Wi-Fi work?
Wi-Fi actually works by using radio waves. An access point or router converts the data received (from a wired connection) into radio waves and transmits it to devices such as smartphones. These then convert it into data that can be watched, read, or listened to. There is a continuous exchange of data between the access point/router and the receiver within the device.
Wi-Fi uses several different bands of radio wave frequencies, predominantly 2.4GHz and 5GHz, but also more recently 6GHz.
WiFi Call Buttons
WiFi call buttons are a brilliant yet simple tool that can be utilised in a variety of industries. Several companies specialise in these, many of which also have useful online resources, such as the examples seen here: www.dinggly.com/products/wireless-call-buttons/.
What are the advantages of using Wi-Fi?
Wi-Fi has several benefits over wired connections. Convenience is perhaps the most obvious one as it means that devices can connect to the Internet in a wider range of places (not restricted by hard wiring).
Wi-Fi can help boost productivity by keeping colleagues in constant contact with each other and enabling cloud-based collaboration. It also enables employees to work when on the move, or in public places (not just at home/in the office).
Any disadvantages/problems?
The first issue has to do with range. As a Wi-Fi signal has a limited range, it may not always be available in the location you need it.
The second possible issue has to do with security. There is some potential for the interception of data that is transmitted over Wi-Fi.
