Does Wi-fi Use Microwaves or Radio Waves?

In this article we have explained and answered frequently asked questions, Does Wi-Fi use microwaves? Is Wi-Fi using radio waves? and Does Bluetooth and Wi-Fi use microwaves? Wi-Fi is without a doubt, an essential aspect of our daily life in our fast-paced digital world. Wi-Fi makes it possible for you to connect to the internet without the use of cables. However, have you at any point ever been keen to discover how the process of connecting to the Internet using Wi-Fi works?

Wi-Fi uses radio waves to transmit information between your device which could be a smartphone, laptop, or computer, and a frequency router. Depending on the amount of data to be transferred, there are two radio frequencies that can be used for transferring and these are 2.4 gigahertz and 5 gigahertz.

Hertz is the frequency of one wave per second while on the other hand, a gigahertz is one billion waves per second. An Internet-supported gadget such as a phone, tablet, or laptop, uses a wireless adapter to convert data into radio waves and send the same waves to an antenna. The radio waves that originate from the antenna are received by a wireless router and the router then converts the radio waves back into data and thereafter, it sends the data to the internet through a physical connection.

This is how all wireless communication work at a high level. However, Wi-Fi has some significant differences from other wireless technologies.

This frequency is much higher than the frequency used for cellular transmission. Higher frequencies mean the signal can carry more data. All forms of wireless communication are at the center of attention between power consumption, and bandwidth. Wi-Fi consumes a lot of power, and it equally does not have much range thereby making low rates for data possible.

Wi-Fi Is Not Great for Most IoT Applications

There are many IoT applications and most of them contain small sensors, such as devices that need to run on battery for months or even years. These sensors and devices do not need to send a lot of data, maybe just a few bytes here or there. They also have to send that data in miles, not just feet.

Wi-Fi can transmit large amounts of data at the expense of high power consumption and short distances. When there are thousands of sensors in the field, Wi-Fi is not a good choice.

Wi-Fi can be great for IoT applications whose concerns do not include power outages (such as plugging in a device) and do not require long-range. The home security system is a very good example in this case.

Nevertheless, there are various other better connectivity options for other IoT applications, these connectivity options, among others include Bluetooth and Low Power Wide-Area Network.

Basically, there are two Wi-Fi standards developed specifically for IoT; Wi-Fi HaLow (802.11ah) and HEW (802.11ax).

Wi-Fi HaLow focuses on addressing the concerns of the range and power performance of IoT applications whereas HEW (High-Efficiency Wireless), is a future model on which HaLow builds in a bid to add more Internet-friendly features.

In conclusion, it has been noted that between radio waves and microwaves, Wi-Fi uses the former.
