🙂 🙂 BLE vs . IEEE 802.15.4

This week, aimless surfing in Internet (my tastes are quite specific 🦄 ) led me to one interesting foreign article. Its authors conducted a comparative analysis BLE and IEEE 802.15.4 in the context of the Internet of Things

😴 I’ll immerse you a little in terms

➡️ Bluetooth Low Energy (BLE) is an energy-efficient version of Bluetooth designed for low-power devices (fitness trackers, smartwatches and other IoT and especially PIoT gadgets)

➡️ IEEE 802.15.4 is a wireless communication standard that underlies the ZigBee, Thread and 6LoWPAN protocols. It is designed to create networks with low power consumption and low data transfer rates

With the growth of IoT systems, it is important that devices can communicate with each other, even if they use different communication protocols ⚡️ ⚡️

So, let's go back to the article.

The study focused on the following aspects:

🍚 Energy efficiency

🙂 Data transfer delay

🏃‍♂️ Data transfer rate

🙂 Communication reliability

❄️ Interference immunity

As a result, the researchers found when comparing technologies that BLE provides low latency, but consumes more power, and IEEE 802.15.4 (especially using TSCH) achieves a better balance between latency and power consumption 💪

🤩 At the same time IEEE 802.15.4 with CSMA offers higher data rates in non-interference environments, while BLE may be inferior in speed, but gains in stability in the presence of interference

If we talk separately about interference, we get that BLE copes better with interference thanks to adaptive channel changing (which is also present in the classic Bluetooth version). IEEE 802.15.4 still more sensitive to various types of interference, but shows excellent results on stable channels 🧐

💯 I will also mention that both protocols support 6LoWPAN. This allows them to work with IPv6 networks, which is ultimately important for the scalability of IoT ecosystems

👨‍🚀 What does this all mean for IoT?

The ability of devices to communicate with each other, even if they use different protocols, accelerates the development of IoT and increases the efficiency of Internet of Things systems, and understanding the strengths and weaknesses of each protocol helps developers choose the best solutions for specific tasks. BLE and IEEE 802.15.4 have their own unique advantages, and the choice between them depends on predefined criteria

🙂 I would say this:

If needed interference immunity , select BLE

If important energy efficiency and high data transfer speed in stable conditions without strong interference, it is worth paying attention to IEEE 802.15.4 .
