The rapid spread of wireless headphones, smart watches and bracelets leads to the active development of the Bluetooth wireless communication protocol. The most modern and up-to-date protocol is considered version 5.0, 5.1 and 5.2. What features are collected in the modern version of the protocol you will learn from this material.
What’s new in Bluetooth 5.0?
Compared to the previous version of Bluetooth 4.2, the changes in the new version contain mainly:
- Increased throughput by a factor of 2 – up to 2 Mbit.
- Increased data transmission range by 4 times – up to 240 meters in an open space.
- Lower power consumption.
- Support of Dual Audio – simultaneous audio transmission to several devices: 2 pairs of headphones, headphones and a speaker, etc.
What’s new in Bluetooth 5.1?
Version 5.1 provides improved positioning and direction-finding.
What’s new in Bluetooth 5.2?
- Improved ATT attribute protocol.
- Availability of a new power control unit, which allows to dynamically adjust the transmitter power of the wireless network to achieve the best results in terms of communication quality and power consumption.
- New LE Audio standard with support for time-linked audio transmission.
Is Bluetooth 5.0 better?
Bluetooth 5.0 includes qualitative improvements over previous versions of Bluetooth. The new version of Bluetooth has increased range and data transfer speed. The changes did not affect only the transmission of sound in wireless headphones. That’s why the developers called the Bluetooth version 5, not 4.3 as originally planned. The Bluetooth standard is regularly improved. That’s why Bluetooth 5.0 remains the best version until a newer version comes along. The next versions of Bluetooth include new features. Improvements concern security and transmitter performance. For now, Bluetooth 5.0 is the minimum version for normal and comfortable use with wireless accessories.
Does Bluetooth 5.0 work with all devices?
Bluetooth 5.0 works with all Bluetooth-enabled devices. The developers have maintained backward compatibility. However, both devices must have the same Bluetooth version in order for all functions to work. If you connect a Bluetooth 2.1 headset to a Bluetooth 5.0 phone, Bluetooth functionality is limited to Bluetooth 2.1. Full Bluetooth 5.0 functionality will be available if the headphones and phone are Bluetooth 5.0.
With Bluetooth 5 all audio devices communicate over Bluetooth Low-Energy. This can make a meaningful difference in battery life, but this isn’t always the case. Apple’s original AirPods are a good example: when connected to an iPhone the Apple W1 chip could “broker” the Bluetooth connection to monitor the strength and make any small adjustments. On an Android phone, it depended on the standard Bluetooth connection. This is why they had better battery life when used with an iPhone.

View the information on the manufacturer’s website or in the device testing software.
What is the maximum range of coverage in bluetooth 5.0?
Up to 40 meters indoors and up to 200 meters outdoors. The range is also affected by the power of the transmitter. Mobile devices usually have less power, computers and laptops often have more.
Is Bluetooth 3.0 or 5.0 better?
Bluetooth 5.0 is better. The Bluetooth 3.0 protocol was introduced in 2009, Bluetooth 5.0 was introduced in 2016. Over 7 years, developers have added various improvements to improve security and data transfer speed.
What phones use Bluetooth 5?
Bluetooth 5 is used in most modern phones. Phones manufactured 1-2 years ago may use Bluetooth 4.2. Bluetooth 4.2 is usually built into inexpensive budget phones. Flagships often contain the latest version of Bluetooth available. Some flagships may contain Bluetooth 5.2 or the latest available version of Bluetooth 5.3.
Which Bluetooth is best quality?
The best version of Bluetooth with the index 5.3. This is the latest version of Bluetooth and contains all possible features of previous Bluetooth versions. However, Bluetooth 5.3 contains a small number of changes and is present in several devices.
Can Bluetooth 5.0 go through walls?
The Bluetooth signal can pass through walls and some obstacles. However, any obstacles impair the signal. Data transmission requires more power, consuming more energy.
How do I know my Bluetooth device is compatible?
All Bluetooth versions contain backward compatibility. Therefore, all Bluetooth devices are compatible. To use all functions, you must connect devices with the same Bluetooth version. You can find out the Bluetooth version from the device’s data sheet or the manufacturer’s official website.
What is the highest Bluetooth version?
The latest version of Bluetooth with the index 5.3. Bluetooth 5.3 was introduced in July 2021.
Is Bluetooth 5.0 old?
Bluetooth 5.0 was introduced in June 2016. Over the past six years, developers have introduced three more versions of Bluetooth with the indices 5.1, 5.2 and 5.3. However, Bluetooth 5.0 has not lost its relevance. The version of Bluetooth 5.0 became mass-produced in 2021-2022. Before that, low-cost smartphones were still equipped with Bluetooth 4.2. Some smartphones are still available with Bluetooth 4.2. Usually this is the cheapest model possible, where the manufacturer has saved on all components. Smartphones with Bluetooth 4.2 are more common in developing countries.
