Radio vs WiFi | Which technology is better? ›

The differences between frequencies

LiFi uses light waves as a medium for communication, while WiFi (wireless fidelity) uses electromagnetic waves (radio waves) at various frequencies. LiFi is considered faster and more secure than WiFi, but it has a shorter range and cannot penetrate walls.

Wi-Fi transmits data using microwaves, which are high-energy radio waves. Wi-Fi is more complicated than FM radio, but the basic underlying technology is the same. They both encode information into radio waves, which are received and decoded. FM radio does this for sound, Wi-Fi does this for computer data.

Wireless is based on radio signals. The term Radio signals is often used for radio broadcast signals by the general audience. Engineers tend to call all wireless HF signals “radio". So, effectively there is technically no difference.

Wi-Fi uses radio waves to transmit information between your device and a router via frequencies. Two radio-wave frequencies can be used, depending on the amount of data being sent: 2.4 gigahertz and 5 gigahertz. What does that mean, though? Well, a hertz is just a measurement of frequency.

Light Fidelity, also known as Li-Fi, uses the power of light to transmit data. Unlike Wi-Fi, which uses radio waves to create a wireless connection, Li-Fi relies on light to transmit data. Through this process, Li-Fi promises speeds that are 100 times faster than Wi-Fi.

Ethernet's main advantage is speed. Since your device is connected directly to the router -- compared to wirelessly through Wi-Fi -- you can expect faster bandwidth, which is how much data you can transmit through an internet connection.

The differences between frequencies

Both are affected by obstacles such as walls and other matching radio frequencies, therefore you have a better chance of reaching the distances you need using low-frequency radio technology. It's also worth mentioning that WiFi units can be vulnerable to connection issues.

You'll need a few things to listen to FM radio on your phone without a data connection: A phone with a built-in FM radio chip: Your phone needs FM radio capability, and that capability needs to be switched on. This requires the manufacturer to activate the functionality, and the carrier to accept the feature.

Radio broadcasting typically focuses on music and talk shows, while internet streaming can provide a wide variety of content, including live and on-demand video, music, and podcasts.

When did wireless change to radio? ›

By 1910, these various wireless systems had come to be called "radio".

Bluetooth allows for short-range data transfer between devices. As an example, it is commonly employed in headsets for mobile phones, enabling hands-free phone use. Wi-Fi, on the other hand, allows devices to connect to the Internet.

What's the difference between AM/FM radio and internet radio? Traditional AM/FM radio relies on direct airwaves and is limited by range and frequency. Internet radio, on the other hand, uses digital signals transmitted over the internet, offering a broader range of content, superior sound quality, and global access.

Health effects of Wi-Fi

There are no health risks from exposure to radiofrequency EMF from Wi-Fi devices in your home, in schools or other areas accessible to the public. These devices must meet standards to ensure they do not exceed radiofrequency EMF exposure limits.

Radio waves can penetrate nonconducting materials, such as wood, bricks, and concrete, fairly well. They cannot pass through electrical conductors, such as water or metals. Above ν = 40 MHz, radio waves from deep space can penetrate Earth's atmosphere.

To access a network via an Ethernet connection, users need to connect a device using ethernet cable. An Ethernet connection is generally faster than a WiFi connection and provides greater reliability and security.

WiFi vs. Internet. To make a complicated concept simple, WiFi refers to a type of wireless connection, while the Internet is what WiFi connects to. You can't have WiFi without Internet, but you can access the Internet without WiFi—most commonly via a wired connection or by using cellular data.

Ethernet cable will ALWAYS give you better performance, lower lag and less problem. Anything that can be connected with an Ethernet cable SHOULD be connected with an Ethernet cable. One reason for this is that makes WiFi to work better when it have to for those devices that do not have an Ethernet cable capability.
