The recent evolution of Bluetooth Mesh, based on BLE, opens up new possibilities. This technology enables the creation of mesh networks supporting up to 32,767 devices. It offers greater resilience and flexibility for large-scale IoT projects.

By combining WiFi and BLE, IoT system designers can exploit the strengths of each technology. WiFi ensures high-speed connectivity, while BLE optimizes energy consumption. This synergy creates versatile solutions to meet the varied challenges of the modern IoT.

Bluetooth Low Energy technical specifications

Bluetooth Low Energy (BLE) transforms the wireless network thanks to its outstanding performance. It enables devices to operate independently for months, even years, after a single recharge. This extended autonomy is a major asset for users.

Frequencies and communication channels

BLE operates at a frequency of 2.4 GHz. It has 40 channels, 2 MHz apart, to minimize interference. Frequency hopping is used to improve the reliability of wireless communications.

GATT protocols and profiles

BLE uses two main modes: broadcast and connection. The broadcast mode allows data to be sent without reception, while the connection mode enables two-way communication. Devices can play different roles in data transmission, such as broadcasters, observers, exchanges or peripherals.

BLE safety mechanisms

Security is essential in BLE. It uses 128-bit AES-CCM encryption to ensure secure communications. Authenticated and encrypted connections protect the data exchanged. Recent versions of Bluetooth, such as 5.0, 5.1 and 5.2, have improved throughput, range and location services, further enhancing BLE's capabilities.

Bluetooth 5.3, the latest evolution, offers reduced latency, better interference management and increased autonomy. It consolidates the reliability of this wireless network technology.

Wi-Fi architecture and operation

Wi-Fi, an essential technology for today's wireless networks, is based on IEEE 802.11 standards. It uses radio waves to establish wireless communication between different devices. Wi-Fi operates mainly on two frequencies: 2.4 GHz and 5 GHz.

Wi-Fi standards and protocols

Wi-Fi communication protocols have undergone a significant evolution. The 802.11n (Wi-Fi 4) standard introduced MIMO technology, increasing data throughput. 802.11ac (Wi-Fi 5) operates in the 5 GHz band, with more extensive channels. The most recent, 802.11ax (Wi-Fi 6), improves performance in very dense environments.

Wi-Fi network infrastructure

Wi-Fi infrastructure is made up of several essential elements. Infrastructure mode uses access points to connect devices. Ad hoc mode enables direct communication between devices. Repeaters extend network coverage. Mesh networks offer wider coverage and greater reliability.

Wi-Fi network architecture

Security and encryption

Security is paramount for any wireless network. Wi-Fi security protocols have evolved from WEP (obsolete) to WPA, WPA2 and WPA3. These protocols guarantee data encryption and user authentication. The use of strong SSIDs and passwords reinforces network security.

BLE and Wi-Fi performance comparison

Wireless connectivity is divided into several options, each with its own advantages. Wifi ble has a number of unique features that set it apart from traditional Wi-Fi.

BLE excels in applications requiring low power consumption. It can manage up to 32,767 devices in a mesh network. This makes it ideal for small data transfers. Its limited range of 10 to 15 meters is ideal for portable devices such as headphones and connected watches.

Wi-Fi stands out for its speed and range. It offers speeds up to 100 times faster than BLE, with a range of up to several hundred meters outdoors. This technology is favored for large, fast data transfers.

The choice between BLE and Wi-Fi depends on your specific needs. BLE is preferable for battery-powered devices. Wi-Fi is better suited to stable, fast connections over longer distances. In some cases, a hybrid approach combining the two technologies may offer an optimal solution for connectivity.

Industrial and IoT applications

The Internet of Things is radically transforming Industry 4.0, paving the way for unprecedented optimization and automation. Connected devices facilitate real-time data collection, significantly improving the efficiency of industrial processes.

Solutions for Industry 4.0

Wireless communication is essential for modernizing factories. Wi-Fi 6, with speeds of up to 9.6 Gbit/s, guarantees reliable transmission in noisy industrial environments. Bluetooth Low Energy, with its 128-bit AES encryption, enhances the security of industrial applications.

Integration into existing systems

Integrating industrial IoT raises challenges, including data security and managing existing systems. Companies need to select the right technologies, taking into account the energy efficiency, reach and scalability required.

Real-life use cases

Concrete IIoT applications include:

  • Monitoring and optimization of production lines

  • Optimizing energy consumption

These solutions increase productivity, reduce maintenance costs and improve operational safety. Analysis of massive sensor data provides valuable insights for decision-making.

Optimizing energy consumption

Efficient power management is essential for connected devices. Bluetooth Low Energy (BLE) stands out for its low power consumption, ideal for battery-powered objects. This wireless technology uses GFSK modulation to reduce energy requirements.

Connected devices adopt intelligent strategies to save energy. They go into sleep mode when inactive, and wake up only to communicate. This approach considerably extends battery life.

Data optimization also plays a key role. Wireless protocols use compression algorithms to minimize the volume of data transmitted. This reduces transmission time and thus energy consumption.

Recent innovations promise spectacular progress:

  • New chips reduce power consumption by a third
  • Underwater data centers reduce energy requirements by 30%.
  • Solar films now power certain Wi-Fi hotspots

These advances extend the use of connected devices to a wide range of fields, including home automation, healthcare and industry, while preserving their autonomy.

Security and data protection

Wireless network security is paramount in today's hyper-connected society. Communication protocols are evolving to counter growing threats. In 2023, 34 million cyberattacks targeted mobile devices, including 307,023 in France.
