4G Cat-M1/NB-IoT Modem
The Yabby's 4G modem is compatible with both Cat-M1 and Nb-IoT networks - enabling great new benefits. Traditional cellular network specifications (like 4G LTE Cat 9/12) are designed to provide high speeds and bandwith - to enable smartphone users to stream videos and facilitate other data-intensive activities.
IoT devices don't need this type of bandwidth and are typically trying to solve other problems. These IoT devices require
- Small data messages typically at low data rates
- Long Range
- Low power to allow for long battery life
- Low cost - to facilitate the deployment of many millions of them
The LTE Cat-M1 and NB1 specifications allow the cellular modem (uBlox SARA R4) to be simpler and smaller, and in turn the Yabby. In our testing we have measured that our new Cat-M1 devices use anywhere from 1/2 to 1/3 of the power of our 3G devices to perform a data upload.
This allows the Yabby to still have excellent battery life (up to 3 years) on just 3 AAA batteries!
