Although 5G attracts everyone’s attention, Wi-Fi 6 can have the same impact in supporting the next generation of IoT devices.
Articles about the impact of 5G on the development of smart cities have become commonplace. However, another technology that has received less attention is Wi-Fi 6, which can play a role behind the scenes and have a revolutionary impact on IoT devices in smart cities, even as good as 5G.
WiFi 6 will provide faster speed, lower latency and higher device connectivity. It will complement each other with 5G, each with advantages and disadvantages. Here are a few ways how Wi-Fi 6 will revolutionize IoT devices:
Compared with Wi-fi5 and 4G, the main advantage of Wi-fi6 is the increase in speed. Wi-Fi 6 is almost three times faster than the original, providing lightning-fast data transfer. With this speed, IoT devices can transmit data at a faster speed, which can greatly reduce their delay and response time. Facts have proved that this is very beneficial for small businesses and residential use. WiFi 6 will be mainly used for indoor networking, whether for commercial or personal purposes. Industries such as hotels, retail, and education can benefit most from WiFi 6, because these industries can adopt IoT devices on smaller networks. The faster speeds provided by WiFi 6 will significantly improve communication between IoT devices and help these industries work better.
IoT devices have their own set of security issues and challenges. WiFi 6 improves security and solves the main problems of current wireless technology. WiFi 6 adopts WPA3 framework, and WPA3 solves the technical defects of WPA2 by designing from scratch. In addition, WPA3 uses Synchronous Authentication Protocol (SAE) instead of WPA2 Pre-Shared Key (PSK) protocol. SAE provides better confidentiality and security than PSK because it has better encryption technology. For hackers, using WiFi 6 protocol to invade devices to obtain private information on IoT devices will become more difficult.
The current WiFi router supports up to 250 devices connected simultaneously. In front of a WiFi 6 router capable of supporting up to 1024 devices at the same time, this number seems insignificant. This will help connect IoT devices to a single routing device with high density. Therefore, WiFi 6 can prove ideal for scenarios like homes and small businesses. This means that a single wireless router is enough to connect a large number of IoT devices, so it also proves to be economical.
However, WiFi is inefficient when transmitting over long distances, because it will face network and connection problems due to obstacles such as walls, buildings, or trees. Therefore, their use in public places will be restricted, and proves to be the most suitable for indoor use Helpful.
Connection is a key condition for the success of IoT devices. Technologies like WiFi6 will greatly improve the performance of IoT devices and prove to be a very safe and economical way to connect to the network. The large-scale introduction and adoption of faster network technologies will pave the way for faster communication methods, improved enterprise productivity, and ultimately the rise of smart cities.
