Technologies have changed our world so quickly, so has itself!
As we all know, 2G/3G have been serving us for decades, thanks to this wireless technology and IoT technology, our world has become more connected and smarter-business owners can use the technology to remotely publish their advertisement via LED display, power companies are able to remotely monitor their substation and power meter, banks have expanded their branches and ATM using cellular routers, etc.
While as the 2G/3G technology is aging, it has to be replaced with newer and modern technology. Today, we’re going to show you some solutions to get your IoT equipment upgraded prior to 2G/3G sunset, to ensure your legacy IoT solutions smooth transition to newer technology.
Before this, do you know why the global mobile network operators are going to shut down their 2G/3G network in schedule?
