Bluetooth is a technology that has managed to remain dormant for over two decades while quietly helping wireless development connect with devices. Speaking of which, have you wondered just how this magic-miracle actually works? Let’s unravel the mysteries of Bluetooth technologies; thus defining our new life in this ever-connected world.
What Is Bluetooth?
Once a Viking dictating the tales of uniting warring tribes into the kingdoms of Denmark and Norway was Harald “Bluetooth” Gormsson. Fast forward some one thousand years; the technology striving for a similar union adopted his name. Thus, the year 1994 saw the creation of Bluetooth, trying to unite the digital world just as its namesake once united Scandinavia.
Visualize the world with no tangled, messy wires. That’s the promise of Bluetooth-a whisper wirelessly communicating with your gadgets. Unlike Wi-Fi, which is a booming broadcast, and cellphone signals, which can theoretically travel across country, Bluetooth is a soft whisper between two gadgets in proximity. Imagine it as a secret handshake exchanged at low-energy radio frequencies. Power consumption being as low as it can get for the closest range connection (usually within 33-65 feet) is probably the best buddy of your battery-powered essentials such as mobile phones, headphones, and all the accessories one feels he or she must have.

Imagine a world all tangled in wires. Then Ericsson, the Swedish telecom giant, visited his mind with a lucid break–a Bluetooth wireless bridge from earphones to the phone. In 1998, the biggest alliance got started: Ericsson, Nokia, IBM, Toshiba, Intel. This was more than a meeting; it was the establishment of the Bluetooth SIG (Special Interest Group), the protector, and poli-connectors of the Bluetooth revolution.
Bluetooth: More than just a feature, it is the universal languages of gadgets. Imagine a world where your phone does not speak to your headphones or a smartwatch cannot whisper heart rate to the fitness app. Chaos, right? That is what Bluetooth is for: it is an agreed protocol-that common ground which affords your devices to connect and communicate seamlessly with each other. Think of it as a secret handshake for electronics. But not all of the secret handshakes are created equal. Get ready to step into the different classes of Bluetooth, each with its distinguishing feature and range.
Class 1 Bluetooth: The mighty champion harnessing the powers of 100 meters. Using a great deal of energy, it can be imagined in industrial areas where distance matters more. Think of giant warehouses and sprawling factories- Class 1 is all about establishing a strong communication network across the expanse.
** :The workhorse of Bluetooth, with the classic range of 3365 feet (1020 meters), it is quite strong and meets the power and supply dynamics.
- Class 3– the least powerful and generally only good for very small distances of 1 meter (3.3 feet).
Give and take is range in Bluetooth parlance. Put it this way: Consider a champion sprinter and a casual jogger. A prospective faster speed for the team from the sprinter gets capped at the jogger’s speed. In exactly the same way, the maximum possible distance is dictated by the weakest class involved in your Bluetooth connection. A Class 1 device with a longer distance capability paired with a regular Class 2 device? They are functioning as per Class 2 standards only.
Tip : turn your Amazon Echo into a Bluetooth speaker.
Types of Bluetooth
Bluetooth comes with two distinct flavors: BR/EDR stands for high Bluetooth bandwidth, while LE is all about low energy. If you’re going old-school with BR/EDR, pairing is a requirement.

Bluetooth LE operates a different way. LE doesn’t always require a prior trusted connection, unlike the standard one. Since Bluetooth 4.0, LE has created a niche in gadgets sensitive to battery drainage like fitness trackers, wireless earbuds, and many other low-power wonders. Now five flavors of LE each have different abilities in the spectrum of what we call Bluetooth today.

Bluetooth Classic (versions 1.0 – 3.0)
Imagine a world where wireless communications trudged at a snail’s pace. There lay the rudimentary Bluetooth 1.0 technology soaring weak under the 1 Mbps hurdle with a shabby 33-foot range. Somehow the Ericsson T39 had to act as the first bearer of this young technology into the mobile world. Bluetooth 2.0 came in as adrenaline in the system, doubling to tripling the speed and hinting of the wireless revolution to happen.
Wi-Fi signals became a secret weapon for Bluetooth 3.0 when sending large files like songs, pictures, or videos, as it slyly allowed Wi-Fi to carry the load. This little acceleration sped up files and allowed transmission at a speed of up to 24 Mbps.
Bluetooth 4.0
Ponder: clunky connections, that old Bluetooth. Enter Bluetooth 4.0 and an epochal and ground-breaking period started: with BLE or Bluetooth Smart. Theoretically, the grandmother could scoop at a gargantuan speed of 25 Mbps, but BLE was made with stamina in mind. Whereas the larger brother is a sprinter, BLE is a marathoneer. At only 1 Mbps, BLE rapidly drilled deep into the veins of tiny tech. Wearables, IoT sensors-those devices where every measly milliamp counts-were all hungry for BLE. BLE gave them the longevity to last for months on end while staying connected rather than for grueling hours.
What about that clunky connection of yore, and the battery eater called Bluetooth? Bluetooth 4.0 started an intellectual and innovative episode; BLE or Bluetooth Smart. While the elder brother can appropriately blow at 25 Mbps, BLE was born with stamina in mind. The elder brother is a sprinter, and BLE is a marathon runner. At 1 Mbps, BLE quickly drilled into the veins of the tiniest tech. Wearables, IoT sensors-those are devices where each milliampere counts-were all vying for BLE. BLE gave them the life to stay connected for months rather than for only hours.
Bluetooth 5.0
Bluetooth 5 bestows more distance and speed to your wireless freedom. Imagine your wireless freedom getting extended beyond the usual limitations, connecting devices in different rooms or even on separate floors. With more room to roam, Bluetooth 5 also compliments low-energy performance with a double data rate. Feel free to choose your speed: from a low energy 125 Kbps to 2 Mbps, Bluetooth 5 adjusts to your service needs with an array of connection possibilities.
Sacrificing the speed brought an unexpected giveaway point: a data reach stretching to a jaw-dropping distance of 240 meters (800 feet)! Just imagine, if only the rules allowed this extent to actually be operational. Then again, any sprinter knows that 2 Mbps is just too fast to carry the longer run when it comes.
Bluetooth 5.3: Released in 2021, this latest Bluetooth is more than just connectivity. Apart from preventing interference, it provides unbreakable security and offers excellent audio quality.

How Does Bluetooth Technology Work?
Imagine the trusty secret handshake the gadgets share. That’s Bluetooth. It takes to the airwaves, whispering in the ears of flimsy contraptions packaged using 79 different radio frequency channels-that, too, being in the crowded 2.4 GHz band. Don’t worry; one should not be pitted against the other. There is ample room in the dance floor for both to mingle.

It would be like a frantic hummingbird darting merrily between 79 different floral sources radio frequencies at random. For, quite unlike normal birds, this hummingbird will not stay on one flower: it will actually dance madly up and down, from one frequency to another hundreds of times a second. This mad dance is anything but; it is the star of the show-one step ahead, a constant, all unconsciously, in dodging the noisy interference of Wi-Fi and other Bluetooth chatterboxes-so that one can be sure that he has a rock-solid connection.
Think of a piconet as a fleeting digital campfire. Wireless devices keep each other company sharing sweet nothings over Bluetooth. One device ebbs and flows with the cord of the conversation: the master ukiyo-e of a sonorous voice, taking account of who has the right to speak at any moment. The others, the conditional slaves, must listen and respond accordingly to one another, forming a temporary tribe of technology. However, unlike in real life, devices can come and go at will from the glow with these temporary networks. These mini-networks connect anywhere from two to eight devices that engage in an ever-changing dance of communication.
Bluetooth pairing goes akin to a digital handshake between items. Devices will announce their presence-if Bluetooth is turned on-so that another device might hear. The master then lists the alternatives nearby and allows you to select your intended partner for a connection. Others may ask for a secret code to finalize the bond, so you’re joining with the right soul mate.

Bluetooth vs. Wi-Fi
Imagine a world without tangled cords. These two make sure to power your smartphone and laptop with wireless magic. But these digital wizards work quite differently to each other’s strengths and secrets.
Bluetooth may be considered a super-close-whisper manner of communication, where insecurities may be shared by-worlded-by-the-devices. However, Wi-Fi is akin to a thunderous announcement that flings open the gates to the vast expanse called the World Wide Web. Connectivity-wise, Wi-Fi can essentially cover the entire home and oftentimes far beyond, measuring up to about 330 feet-and then some! While Bluetooth, standing almost at par, would not be able to work beyond an arm’s length. But speed-wise, Wi-Fi really dallies around and takes forever to get through transfers.
Bluetooth: a mighty master in the realm of battery life. Swaying to the slow rhythms of energy consumption, it is, for sure, an extremely amicable partner to your battery-challenged device. Wi-Fi, in contrast, is a thirstier presence, demanding electricity to keep the connection alive and then maintain all those data streams.
