Can WI-FI 6 revolutionize IoT applications?
Although 5G attracts everyone's attention, Wi-Fi6 can also have the same impact in supporting
the next generation of IoT devices.
Articles about the impact of 5G on the development of smart cities are common. However,
another technology that has received less attention is Wi-Fi6, which can play a role behind the
scenes and have a revolutionary impact on IoT devices in smart cities, even as much as 5G. WiFi6
will provide faster speeds, lower latency, and higher device connectivity. It will complement each
other with 5G, each with its advantages and disadvantages. Here are a few ways how Wi-Fi6 will
revolutionize IoT devices.
Faster speed
Compared with Wi-fi5 and 4G, the main advantage of Wi-fi6 is the increase in speed. Wi-Fi6 is
almost three times faster than the original and can provide lightning-fast data transmission. With
such speeds, IoT devices can transfer data faster, which can greatly reduce their latency and
response time. This has proven to be very beneficial for both small businesses and residential use.
WiFi6 will be used primarily for indoor networking, whether for commercial or personal purposes.
Industries such as hospitality, retail, and education can benefit the most from WiFi6, as these
industries can adopt IoT devices on smaller networks. The faster speeds provided by WiFi6 will
significantly improve communication between IoT devices and help these industries work better.
Improved security
IoT devices have their own set of security issues and challenges. WiFi6 improves security and
solves the main problems of current wireless technologies. WiFi6 uses the WPA3 framework, and
WPA3 is designed from scratch to solve the technical defects of WPA2. In addition, WPA3 uses the
Synchronous Authentication Protocol (SAE) instead of the WPA2 Pre-Shared Key (PSK) protocol.
SAE provides better confidentiality and security than PSK because it has better encryption
technology. It will be more difficult for hackers to use the WiFi 6 protocol to invade devices to
obtain private information on IoT devices.
Enhanced scalability
Current WiFi routers support up to 250 devices connected at the same time. In the face of a
WiFi6 router capable of supporting up to 1024 devices at the same time, this number seems
trivial. This will help densely connect IoT devices to a single routing device. Therefore, for
scenarios such as homes and small businesses, WiFi6 can prove to be ideal. This means that a
single wireless router is sufficient to connect a large number of IoT devices and therefore proves
to be economical. (From the House of Things) 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, so their use in public places will be limited And proved to be most
beneficial for indoor use.
Connectivity is a key condition for the success of IoT devices. Technologies like WiFi6 will greatly
improve the performance of IoT devices and have proven to be a very secure and economical way
to connect to the network. The large-scale rollout and adoption of faster network technologies
will pave the way for faster communication methods, increase enterprise productivity, and
ultimately the rise of smart cities.
