Bluetooth behavior can get patchy when the RF spectrum is crowded in the city or at a gym. The wireless link between cell phones, speakers, and headphones is categorized as Bluetooth Class 2, which has a stated range of 10 meters 33 feet and uses up to 2.
However, even communication with a Class 2 device like a speaker over a distance of five meters may not work particularly well, since generally devices need a clear line of sight for optimal transmission—disruptions from walls, doors, even people can cause problems.
Bluetooth hops between different frequencies. If you move around, carrier frequencies can drop off, requiring some re-profiling of the connection. This happens automatically, but can make the audio choppy momentarily, or may even interrupt it completely. Related: True wireless vs wireless Bluetooth. The biggest problem is that several wireless protocols are competing for bandwidth, including all of your 2.
Bluetooth transfers data much slower than Wi-Fi does. Under ideal conditions, 2. Bluetooth 5 offers data transfer speeds of up to 2Mbps—double the rate supported by Bluetooth 4. Even with the speed improvement, Bluetooth 5 will be slow to correct if data gets lost compared to Wi-Fi, and thus more prone to dropouts and glitches. Bluetooth has a relatively complex handshaking protocol, which can fail if there is corruption of any data packet exchanged during the process.
In this case, the handshake has to start over, which slows down the pairing process. The process for pairing devices can vary. It might involve entering a PIN code into your phone or computer, particularly with older peripherals.
Thankfully newer products have moved on from this approach. With many, you can use Near Field Communication NFC and physically touch your phone to the device you want to pair it with—this feature is common on Android devices. Generally, Bluetooth is backwards compatible: Bluetooth devices supporting the current Bluetooth 5.
Devices may not connect, they may randomly disconnect, or you can run into interference from other devices. Here's why the technology has so many problems, and what you can do to fix it. Following is a transcript of the video. You're not alone. Apple, Google and other companies have gotten rid of the headphone jack from their phones.
This is pushing people towards wireless headphones, which means they'll have to rely on that Bluetooth connection. But Bluetooth is still so unreliable. Its got a short range, devices disconnect randomly and it uses up battery life. Even thought it's been around for 20 years, Why does Bluetooth still suck? Bluetooth is a wireless standard used all around the world.
Wireless printers, keyboards, game controllers, speakers and headphones all use it. It was created by a group of engineers in the mid-'90's as a secure way to exchange data between devices. The Bluetooth name and logo come from 10th century Viking king Harald Gormsson who, similar to Bluetooth's purpose, unified two separate entities, Denmark and Norway. King Harald's nickname was Blatand, which translates from Danish to Bluetooth.
The logo comes from the initials of King Harald Blatand. It is a combination of the runic letters H and B. Bluetooth uses the 2. This is the spectrum that baby monitors and cordless phones all use. It's also the same frequency fluorescent lights and microwaves emit. Uhura, and security guys wore them. People talked to themselves in public. Once upon a time, Bluetooth headsets were all the rage, filling mall kiosks and Best Buy stores.
And it seemed that everyone who was anyone had a Bluetooth headset to accompany their new Blackberry or iPhone. How times have changed! The wireless headset was the killer use for newfangled Bluetooth technology, back when it was a feature worth mentioning. Once a Bluetooth-equipped BlackBerry, Palm, or Nokia appeared, a headset was a must-have accessory to exploit this newfound wirelessness.
Now you could leave your phone in your pocket and jabber in public, annoying passers-by and making yourself look like a crazy person!
