From Ice Boxes to the Cloud: Cold Chain Monitoring's Journey and the 2G/3G Sunset's Impact

The cold chain has come a long way since its early days, relying on ice to maintain food freshness during transport. Today, sophisticated monitoring solutions ensure the safe and efficient delivery of temperature-sensitive goods across vast distances. But with the impending 2G and 3G network sunset, the industry is on the cusp of another significant transformation.

A Look Back: The Evolution of Cold Chain Monitoring

  • The first attempts at cold chain management utilised natural resources like ice and snow to preserve food during transportation.
  • 20th Century: The invention of refrigeration units and mechanically cooled trucks revolutionized the cold chain.
  • 1990s and Beyond: Electronic temperature data loggers and real-time monitoring systems transformed the industry, offering greater data accuracy and improved decision-making capabilities.

The 2G/3G Sunset: Reshaping the Landscape
The impending 2G and 3G network sunset presents both challenges and opportunities for the cold chain industry:


  • Disrupted connectivity: Existing monitoring systems relying on these networks will face connectivity issues, potentially compromising temperature data transmission and jeopardising product quality.
  • Business continuity risks: Disruptions in temperature monitoring can lead to product spoilage, operational delays, and financial losses.


  • Embracing innovation: The shift necessitates the adoption of future-proof solutions, such as 4G LTE and 5G-ready devices.
  • Enhanced efficiency: Advanced data analytics and cloud-based platforms offer improved data accessibility and can streamline operations.
