Bluetooth 5.0 vs. 5.1: What are the differences?

Congratulations on your new gadget with Bluetooth 5.1! You may wonder what sets this version apart from its predecessor, Bluetooth 5.0. Don’t worry. We’ve got you covered. In this article, we’ll explore the differences between Bluetooth 5.0 vs. 5.1, so you can fully understand the capabilities of your new gadget. So please sit back, relax, and let’s dive into the world of Bluetooth!

What is Bluetooth 5.0

Bluetooth 5.0 is one of the last versions of the wireless communication technology standard. It was introduced as an upgrade to its predecessor, Bluetooth 4.2, and was officially released in late 2016. Bluetooth 5.0 significantly improves over its previous versions regarding data transfer speed, range, and overall performance. One of the key features of Bluetooth 5.0 is its enhanced data transfer rate. It supports a maximum data transfer speed of 2 Mbps, twice as fast as Bluetooth 4.2. This improvement enables faster file transfers and more seamless streaming of high-quality audio and video content.

Bluetooth 5.0 also extends the range of wireless communication. It provides four times the range compared to Bluetooth 4.2, allowing devices to maintain a stable connection even when they are farther apart. This expanded range is particularly beneficial for smart home devices, enabling better connectivity between devices in different rooms. Another notable feature of Bluetooth 5.0 is its improved energy efficiency. It introduces a Low Energy (LE) Advertising Extension that allows devices to transmit data more powerlessly. This enhancement is crucial for IoT (Internet of Things) devices and wearables, as it helps prolong battery life and optimize overall energy consumption.

Besides, Bluetooth 5.0 enhances connection reliability and coexistence with other wireless technologies. It implements a “2 Mbps LE” feature that reduces interference from nearby wireless devices, resulting in more stable connections and improved performance in congested environments.

bluetooth 5.1 features

In a nutshell, Bluetooth 5.0 significantly improves data transfer speed, range, energy efficiency, and connection reliability, making it a valuable upgrade for various applications, ranging from smartphones and laptops to smart home devices and IoT solutions.

However… is there any other better version of Bluetooth? Let’s find out.

What is Bluetooth 5.1

Bluetooth 5.1 is an upgraded version of the wireless communication technology standard known as Bluetooth. It introduces several new features and enhancements compared to its predecessor, Bluetooth 5.0.

Bluetooth 5.0 vs. 5.1: What are the new features?

Advertising Sync Transferring

Bluetooth 5.1 introduces a feature called Advertising Sync Transferring, which enhances the accuracy of device tracking and positioning. This feature allows devices to exchange information about advertising packets, enabling more precise determination of the direction and proximity of Bluetooth devices. Compared to Bluetooth 5.0, which had limited capabilities for tracking and positioning, Bluetooth 5.1 offers improved location-based services and navigation, making it particularly useful for applications such as indoor positioning systems and asset tracking.

GATT Caching Enhancements

Bluetooth 5.1 enhances the Generic Attribute Profile (GATT) caching mechanism. GATT caching allows devices to store and retrieve attribute information exchanged during Bluetooth connections, reducing the need for frequent attribute exchanges. With Bluetooth 5.1, GATT caching is further optimized, resulting in improved power efficiency and reduced latency compared to Bluetooth 5.0. This enhancement is particularly beneficial for devices that rely heavily on GATT-based communication, such as fitness trackers and smartwatches.

Accurate Tracking

Bluetooth 5.1 introduces the Direction Finding feature, which enables accurate tracking of Bluetooth devices in real time. This feature leverages the Angle of Arrival (AoA) and Angle of Departure (AoD) methodologies to determine the direction of the Bluetooth signal, allowing devices to locate and track each other’s positions precisely. By enabling accurate tracking, Bluetooth 5.1 offers enhanced capabilities for applications like asset tracking, indoor navigation, and location-based services. In comparison, Bluetooth 5.0 lacked these direction-finding features, limiting its tracking capabilities.

Improved Coexistence with Wi-Fi

Bluetooth 5.1 addresses coexistence challenges with Wi-Fi by introducing mechanisms to reduce interference between the two wireless technologies. It implements Isochronous Channels, which enable time-synchronized communication between Bluetooth devices. By synchronizing transmission times, Bluetooth 5.1 minimizes the potential for interference with Wi-Fi signals, leading to improved performance and reliability in environments where both technologies coexist. Bluetooth 5.0 did not have specific provisions to mitigate Wi-Fi interference, making Bluetooth 5.1 a preferable option for scenarios with significant Wi-Fi usage.
