What is GSM?

GSM is the technology behind regular mobile devices communicating with each other by the use of SIM cards provided by various networks.

Why does Agua use GSM instead of various technologies available today?

In our 3 years of Research and Development of water management systems we have tried and tested almost all the technologies available for IOT integration. Following are our findings in respect to these technologies:

GSM Advantages

  • Can be controlled from any where in the world
  • Doesn't rely on cabled networks
  • No maintainance
  • Plug and Play deployment, no specialized installation
  • Remote access is never lost as the device can connect to any other available tower

Various technology limitations

  1. BLUETOOTH
    • It has very limited range for mobile connectivity and can only be used in close proximity (<10 meters)
    • Multiple device configuration is difficult, only one mobile device can access an automation system at a time
    • Compatibility with growing technology can render automation hardware redundant in a few years
    • Configuration of automation hardware is a challenge for users
  2. WiFi
    • Devices have limited range (<60 meters)
    • Configuration of network passwords is a challenge for users as it is a "Techie friendly" process and not targeted at the general population
    • Automation device positioning needs to be strategic and can't be done far away from the source
    • If the initial network password/name is changed, the general population will require a trained professional to visit them. This hampers the product scale-ability.
  3. Ethernet
    • Maintenance of network cables is a hassle
    • Requires repeaters every 100 meters
    • Third party service providers rely on cabled networks which are not 100% reliable
    • The connectivity can be lost from any point in the long network chain
