What’s the Difference Between Bluetooth and Wi-Fi?

“Wireless” is a term that “wireless” has been used for over 100 years. It was first used to describe the use of wires for communication that were not telegraphed and then was used as the name for what is now more commonly referred to in the present as radio.

They are both synonymous was the claim Edward C. Hubert emphatically made in his book “Radio Vs. Wireless” in 1925.

“Wireless is the term used to describe communication that does not require the necessity of wires that are not aerial, with the ground and the ether replacing wires. Radio refers to the same thing. It is the same thing.”

When people are told “wireless,” we likely do not think of radio. However, radio waves still play a role in how Bluetooth and WiFi function, allowing your devices to connect to the Internet.

It’s the Birth of Bluetooth

The exciting aspect of”Bluetooth” is that the meaning behind “Bluetooth” is it’s a lot more old-fashioned than wireless technologies. According to the company that came up with the name, it was the name of King Harald “Bluetooth” Gormsson who brought together Denmark and Norway back in 958. The character made the most of the hue of his deceased tooth.

In 1996, Jim Kardach from Intel suggested the name about the concept of unification: “King Harald Bluetooth…was famous for bringing together Scandinavia in the same way we wanted to unify the cellular and PC industries by establishing the short-range wireless connection.” Although it wasn’t planned to be the finalization of the name, it did end up being.

One of the names they considered variations of PAN, which stands for Personal Area Networks. The person on the list is the distance in the range of a human. The reason for this is that the signal will not typically extend past 30 feet.

Distance between Bluetooth devices is typically shorter, for example, if you have a wireless keyboard within a few feet of your laptop or a wireless headset close to your mobile. In simple terms:
“Bluetooth operates in Bluetooth operates within the 2400-2483.5 MHz band in the ISM 2.4 GHz frequency band. The data is broken down into packets and then transmitted via any or more of the 79 Bluetooth channels (each of which has 1 MHz of bandwidth).”

This is the BLE version

Like any other technology, Bluetooth did not remain in a static state. The initial form, which people refer to as Bluetooth Classic, was changed multiple times, particularly in 2011, when Bluetooth released version 4.0 AKA Bluetooth Low Energy (BLE) which led people to call the different variant with the name of Bluetooth Classic (BC).

The method by which BLE can reduce energy usage is to stay asleep until activated by activation via an internet connection. Its energy savings is impressive.

According to the Droids on Droids, an Android blog, it can attain “as much as 100x lower energy consumption” over its predecessor. It’s because while BC consumes a full one watt, BLE only consumer 0.1-0.5 power.

The blog explains how it functions:

“The data is transmitted via tiny (20 bytes) packets; however, the distance could be greater than 100m (330 feet) and is the fastest time between two states not connected and data transfer can be measured in milliseconds. In BT Classic, it’s about 100 milliseconds.”

So that all it takes to power the most basic BLE equipment is a tiny battery. A coin cell battery can be used for about two years, as per the website.

What’s the reason? Bluetooth Classic is Still in Demand

Due to the remarkable effectiveness of BLE, One might think that it has completely replaced the traditional version. However, this isn’t the case because the version with low energy is not capable of providing continuous transmission, which we’ve come to expect from our computers and mobile phone tasks.

Many are willing to sacrifice battery power “for continuous two-way data transmission with a high rate of Application speed (up at 2.1 Mbps),” the blog explained. This is why Bluetooth that allows “streaming audio and videos, or other devices that require an ongoing, broadband connection” is the standard version.

The way to connect PAN to LAN via WiFi

As with Bluetooth WiFi, WiFi operates on the radio frequency. However, it’s not restricted to the comparatively short distances and the data load of PAN. It also allows the LAN (local area network). Within that network, WiFi-enabled devices can connect as long as they’re within the range of the wireless signal. This range could be as far as 300 feet.

WiFi is a trademarked term that refers to devices that use the IEEE 802.11 standards. Manufacturers of products must pass tests for WiFi interoperability, which WiFi Alliance conducts. WiFi Alliance, to identify the device’s WiFi.

It was first introduced in 1994. WiFi works on 2.4, 3.6, and 5 GHz and has a speed of 11 Mbps and a time to connect of 150 milliseconds. It is typically used for users to connect to the Internet to ensure that your office, home, library, or the hotel could be equipped with multiple devices that can take advantage of the Internet without having to be connected.

This kind of connectivity is the reason that is making this Internet of Things (IoT) feasible, allowing for smart homes, devices, and appliances that are accessible via the Internet from any location. The drawback is that it could also be an area of vulnerability that could be hacked by an aquarium or similar.

WiFi Direct: Similar to Bluetooth However, it is a bit different

While it’s not a way to get connected to the Internet, WiFi can be used now to directly connect two devices through WiFi Direct, which is more like Bluetooth in terms of functionality than standard WiFi.

The official website describes:

WiFi Direct devices connect from anywhere and at any time, even when there’s no access to an internet connection nearby. WiFi Direct devices send signals to other devices within the vicinity, knowing that a connection has been established. Users can view the available devices and then request references or get invites to connect to a different device. In the event that there are two or more WiFi Direct-certified devices connect to create a Direct WiFi group that uses WiFi Secured Setup(TM).

WiFi Direct connections can be faster than WiFi connections made via the Internet as they only require a single-hop instead of two–one for the router and the other for the device you wish to connect to. It’s similar to flying directly without traveling to the airline’s hub and then taking a second hop towards your destination.

It is indeed similar to Bluetooth’s functionality. The main distinction is that you can receive much faster speeds using WiFi direct. Bluetooth can handle more than 50 megabits/s, while WiFi direct has rates of up to 2Gbits/s. That’s the speed you require for optimal gaming experiences and intelligent TVs, high-resolution photos and videos, and more decadent sounding music.

However, faster speeds come with a price in the case of WiFi direct this means more energy use that can reach 20 watts, compared to BLE’s use at 0.01 watts. That is an essential consideration in the case of small battery power for mobile devices.

The Answer The Answer: All of the above

The different forms that are available for Bluetooth and WiFi aren’t necessarily distinct. The majority of us use all of them.
The various types of connectivity exist in our workplaces, cars, and our homes and libraries. They allow us to have the connectivity we require that can provide the range and the amount of power necessary to ensure that our interfaces are seamless as we move from our laptops to tablets, smartphones, and intelligent devices.
