Have you ever experienced spotty connections or lagging music when streaming from your Bluetooth speakers or headphones? These annoyances could likely have been minimized if your devices supported the latest Bluetooth 5 standard.
Bluetooth technology allows electronic gadgets to wirelessly share data over short distances using radio transmissions. First introduced in 1999, Bluetooth has evolved through several versions incrementally improving speed, range and connectivity. Bluetooth 5 represents the biggest leap forward yet for the most popular short-range wireless standard on the planet.
This guide will cover everything you need to know comparing Bluetooth 5 vs 4:
- Key Specification Differences
- Real-World Performance Impacts
- Backward Compatibility Considerations
- Recommendations for Consumers
We‘ll analyze how Bluetooth has advanced to better meet demands of modern wireless media streaming and the Internet of Things (IoT) through faster data transfers and expanded device capacity. Let‘s start with a quick primer on the Bluetooth standard evolution itself…
A Brief History of Bluetooth Standards
The story began in 1994 when Ericsson first conceived of a low-power radio interface they called MC Link. Several years later this was formally branded as Bluetooth, named after a 10th century Scandinavian king.
The Bluetooth Special Interest Group (SIG) released the initial 1.0 specification in 1999. This first version had a peak transmission rate of 1 Mbps with maximum range of 10 meters.
Here‘s a quick overview of major Bluetooth versions since:
- Bluetooth 1.1 – Added support for non-encryptable channels
- Bluetooth 2.0 – Faster Enhanced Data Rate (EDR) of 2-3 Mbps
- Bluetooth 2.1 – Extended Inquiry Response for better device discovery
- Bluetooth 3.0 – High Speed protocol for bursts up to 24 Mbps
- Bluetooth 4.0 – Low Energy protocol for battery-powered IoT devices
- Bluetooth 4.2 – Internet Protocol Support Profile (IPSP)
- Bluetooth 5 – 2x speed, 4x range, 8x broadcast capacity
The latest Bluetooth 5.3 release builds on 5.0 with direction finding, longer range and scanning.
Bluetooth 5 Significantly Closes Speed and Range Gap
The major improvements delivered in Bluetooth 5 can be summarized by faster data transfers and extended device reach. Let‘s explore the key specification differences vs the Bluetooth 4 standard:
| Feature | Bluetooth 4 | Bluetooth 5 |
| Max Speed | 1 Mbps | 2 Mbps |
| Outdoor Range | 60m | 240m |
| Broadcast Capacity | 1 device | Up to 8 devices |
We can see Bluetooth 5 doubles the max data transfer rate to 2 Mbps compared to Bluetooth 4‘s 1 Mbps peak. But more impactful for real-world usage is the extended coverage range…
Bluetooth 5 quadruples the max outdoor transmission distance to 240m – nearly 3 football fields! This allows you to place Bluetooth speakers much further apart or control smart home devices from anywhere in your house.
