The 10 Best Bluetooth Speakers With Lights
What Is Bluetooth And How Does It Work?
Simply put, Bluetooth is a form of wireless communication technology that allows certain gadgets to connect with other compatible electronics nearby. It was designed specifically for communication across short distances, with most devices usually having a range of up to 30 feet. Some of its common uses include transferring files between two devices, streaming audio through wireless speakers, and even playing multiplayer games.
Bluetooth works by sending and receiving radio waves through antenna-equipped microchips. It operates in the unlicensed industrial, scientific, and medical radio band at around 2.4 to 2.485GHz. Bluetooth devices can communicate with each other as long as they're within range. In order to avoid unintentional interference, Bluetooth uses a technique called frequency hopping spread-spectrum. With FHSS, a pair of devices will constantly hop around different unused frequencies, sending small packets of data through each before switching to the next.
Aside from FHSS, Bluetooth devices also avoid interference by only consuming very little power. The downside to this feature is that Bluetooth tends to be very slow compared to Wi-Fi. Because of this, it is typically only used to reliably transfer a few megabytes worth of data at a time.
Whenever devices connect to one another through Bluetooth, they form what's called a piconet, which is a term used to describe a very small network. Bluetooth-capable gadgets can connect with up to seven different devices under a Master/Slave model, which basically means that one "master" device coordinates the communication between "slaves" within its own piconet. For example, if you connect your phone to a wireless speaker, your phone acts as the master that can transmit audio data to that speaker.
Choosing A Speaker With Lights
There are a few things you have to consider when choosing a Bluetooth speaker with lights. First of all, you have to figure out exactly what you're going to use the speakers for. For example, if you plan on using it for parties or large gatherings in general, you may want to get one of the bulkier models with a built-in subwoofer. If you need something that's portable, you should get one of the smaller speakers with rechargeable batteries that can last for several hours.
Another thing you should consider is the type of light you need. Bluetooth speakers typically make use of programmable LED lights. Some of the major brands, such as JBL, manufacture speakers that support apps that let you customize how the lights are displayed and whether or not you want them to react to the music. There are also models designed to double as table lamps, which are perfect for people who want to play ambient music while they work or study.
You should also take note of what version of Bluetooth a speaker uses and whether or not it's compatible with whatever device you plan on pairing it with. Ideally, you'll want to get something that has Bluetooth 4.0 and above, because these devices are designed to consume much less power than their previous iterations without reducing their effective range. If you need something with more reach, you should consider buying a speaker that runs version 5.0, which has a range of over 200 meters.
Finally, it should also be noted that most mobile devices can only stream through one audio device at a time. There are a few speakers that have the ability to sync with at least one other speaker of the same brand though. If that's not an option, you can still sync two different audio devices if you're using a phone that has Bluetooth 5.0, because it will most likely have a "Dual Audio" option.
A Brief History Of Bluetooth
In 1989, a Swedish telecommunications company known as Ericsson started developing radio technology that allowed computers to interact with wireless headsets. By the mid-1990s, Ericsson engineers Jaap Haartsen and Sven Mattisson invented the MC-Link, which aimed to let devices interact with one another without using a cable. In order to operate worldwide, they had to make use of a license-free radio band. This means that unless they constantly hop frequencies, Bluetooth devices are prone to interference from several sources, such as microwave ovens and wireless phones.
Throughout the decade, other companies (most notably, Nokia and Intel) started experimenting with the idea of short-range peer-to-peer connections between mobile devices and computers. Eventually, they realized that they needed to work on a universal standard so that devices from different companies could seamlessly connect with one other. In 1996, Ericsson, IBM, Intel, Toshiba, and Nokia formed the Bluetooth Special Interest Group or "SIG" for short. It's a non-profit organization that oversees the development and licensing of Bluetooth tech.
The name "Bluetooth" was proposed by an Intel engineer named Jim Kardach. When the companies first met to form the SIG, Kardach mentioned that he was reading a history book about Vikings that featured King Harald Bluetooth. Bluetooth was a king from the 10th century that managed to unite the many Scandinavian clans under one banner. In the same sense, their technology aimed to unite the wireless industry under one standard.
Bluetooth continues to develop over the years, with new versions being released every now and then. When the SIG first released Bluetooth 1.0, it was slow and riddled with compatibility issues. Since then, they've made significant improvements to its speed and range with every new version, and one can easily assume that this trend will continue as technology advances over time.
