LoRa vs WiFi vs BLE: Which One to Use in Your IoT Project?

In this guide, we'll dive into what sets LoRa, WiFi, and BLE apart, and most importantly, help you determine which one suits your project best.

Once you've got your prototype all set up, keep in mind that companies like PCBONLINE help you move from the initial R&D stage to having professionally manufactured and assembled PCBs.

Overview of LoRa, WiFi, and BLE in IoT

In today's rapidly evolving world of IoT, or the Internet of Things, picking the right wireless communication technology can make a difference for your project. Whether you're working on a smart farming solution, a fitness tracker, or a fully connected smart home, the way your device sends and receives data reliably is important.

When we talk about popular wireless protocols in the IoT arena, three names pop up quite a bit: LoRa, WiFi, and BLE, which stands for Bluetooth Low Energy. Each of these has its own perks and drawbacks, and they shine in different scenarios.

LoRa (Long Range)

LoRa is a low-power, long-range wireless technology optimized for small data packets over vast distances used in remote, outdoor environments.

• Range: Up to 15 km (line-of-sight)
• Data rate: 0.3–50 kbps
• Power consumption: Extremely low
• Best for: Agriculture, environmental monitoring, asset tracking
• Application example: wildfire alarm

WiFi

WiFi offers high-speed data transmission and is ideal for applications that require frequent internet connectivity and high bandwidth, like smart home systems or surveillance.

• Range: 50–100 meters indoors
• Data rate: Up to several Gbps
• Power consumption: High
• Best for: Smart appliances, video cameras, cloud-connected devices
• Application example: smart door lock

Bluetooth Low Energy (BLE)

BLE is designed for short-range, energy-efficient communication. It's a go-to choice for wearable devices and personal electronics.

• Range: 10–100 meters (depending on the environment)
• Data rate: Up to 2 Mbps
• Power consumption: Ultra-low
• Best for: Wearables, fitness trackers, medical sensors
• Application example: face-ID check-in

Example Hardware Modules

Your wireless protocol choice influences hardware and PCB design. Here are some widely used modules that incorporate each protocol:

ESP32 – WiFi + BLE

The ESP32 is a dual-core microcontroller with integrated WiFi and BLE. It's low-cost and packed with features.

• Popular in: Smart home, wearables, industrial IoT
• Design note: ESP32-based designs are supported by PCB manufacturers like PCBONLINE, who can provide multilayer PCB fabrication, SMT assembly, testing for WiFi/BT signal integrity, enclosures, box-build assembly, IC programming, and value-added.

RAK4630 – LoRa + BLE

The RAK4630 combines LoRa and BLE, allowing for versatile deployments in rural or mobile IoT solutions.

• Popular in: Smart farming, GPS asset tracking
• Design note: LoRa designs typically require careful PCB antenna layout and RF shielding. A partner like PCBONLINE, with RF/high-frequency PCB experience, can help minimize signal loss and EMI.

HM-10 (BLE) & HC-05 (Classic Bluetooth)

These modules are simple and cost-effective for basic Bluetooth communication.

• Popular in: Low-cost IoT gadgets, hobbyist projects
• Design tip: For low-cost, high-volume production, PCBONLINE offers turnkey PCBA services, including sourcing of modules like HM-10 or equivalent chipsets for BLE.
