Why Cellular is Better than WiFi and Bluetooth for IoT Devices

The IoT space has been dominated by WiFi and Bluetooth-related products. However, these technologies often come with significant drawbacks that hinder their effectiveness and user experience. Let’s explore why cellular connectivity, such as that used in Centri’s propane tank monitor, offers a superior solution.

Common Issues with WiFi and Bluetooth

Many IoT devices rely on WiFi or Bluetooth for connectivity, but these methods are fraught with challenges:

Configuration Hassles: Users frequently encounter issues like “Add your WiFi Password,” “Waiting to find Bluetooth device,” or “Pair Bluetooth device.” These setup steps can be cumbersome and frustrating, often leading to multiple support requests that may not get timely responses from the companies. For example, WiFi networks often require entering passwords and configuring network settings, which can be especially difficult for non-technical users.
Range Limitations: WiFi and Bluetooth have limited ranges. Propane tanks are often located 20+ yards (60+ feet) away from the home, which can exceed the effective range of a home WiFi router or Bluetooth connection. This necessitates the additional purchase of signal extenders, adding to the overall cost and complexity. Moreover, Bluetooth typically supports shorter ranges (up to about 100 meters in optimal conditions), making it less suitable for large properties.

Advantages of Cellular Connectivity

Cellular connectivity offers several distinct advantages over WiFi and Bluetooth for IoT devices:

Ease of Installation: The Centri propane tank monitor is designed to be straightforward to install and configure. Unlike WiFi and Bluetooth, which require network setup and pairing, cellular devices connect automatically once powered on, provided there is cellular coverage. This “plug and play” simplicity is a significant advantage for end-users who may not be tech-savvy.
Comprehensive Coverage: Cellular networks provide extensive coverage, allowing devices to connect from virtually anywhere. This is particularly beneficial for remote locations where WiFi or Bluetooth signals are weak or non-existent. Cellular networks cover wide geographic areas and can provide connectivity in rural and remote locations where WiFi is unavailable.
Included Costs: Centri’s propane tank monitor includes the cost of cellular service for the product’s lifespan, typically 10 years, without any recurring fees. This eliminates the need for ongoing subscription costs, which is a common issue with other connectivity options. This makes it more cost-effective in the long term, as users do not need to worry about additional charges for connectivity.

Why Centri Chose Cellular

Centri’s decision to use cellular connectivity was driven by the need for simplicity and reliability:

Customer Feedback: Customers have expressed frustration with previous tank monitors that were difficult to pair, had limited range, or came with recurring fees. By using cellular connectivity, Centri addresses these issues directly, providing a hassle-free user experience. This approach significantly reduces the setup time and the need for technical support.
Reliable Performance: Cellular networks offer robust security and reliable performance, with automatic encryption ensuring data privacy. This is critical for IoT devices that need to operate seamlessly without manual intervention. The robust security protocols inherent in cellular networks provide an additional layer of protection against data breaches.

Practical Use Cases

For IoT applications such as propane tank monitoring, cellular connectivity proves to be the most reliable and efficient option:

Remote Monitoring: Many propane tanks are installed far from residential buildings, making it difficult for WiFi or Bluetooth to maintain a stable connection. Cellular connectivity ensures consistent data transmission regardless of the tank’s location.
Cost-Effective Solution: While the initial hardware cost for cellular devices may be higher, the total cost of ownership is often lower due to the elimination of additional network infrastructure and recurring fees.

Conclusion

Cellular connectivity in IoT devices, such as Centri’s propane tank monitor, represents a significant advancement over WiFi and Bluetooth. It offers unparalleled ease of installation, extensive coverage, and long-term cost savings. For homeowners, especially those with remote properties or those renting out their homes on Airbnb, cellular-connected devices provide the most reliable and user-friendly solution available.
