Able Device, based in Raleigh, North Carolina, provides standards-based enabling technology that simplifies and accelerates the development and deployment of Internet of Things (IoT) applications on mobile networks. SIMbae, our patented offering, enables standard Subscriber Identity Modules (SIMs or embedded eSIMs), which are inserted into all mobile devices with Mobile Network Operator (MNO) subscriptions, to act as stand-alone processors that run device management tools and / or applications in IoT devices. By utilizing the processing power of SIMs / eSIMs we’re able to provide a standards-based, yet unique way to shift security, intelligence, and Quality of Experience (QoE) to the extreme edge of a mobile IoT solution, eliminating the need for data services to access off-board intelligence residing in the cloud.
SIMbae, a small Java Card software applet, embeds on any standard SIM or eSIM. The SIM is the only standard component contained in every IoT device connected to mobile networks. SIMs are small, very secure processors with operating systems, standard file structures, form factors, and logical I/Os. Although SIMs can run applications, they have traditionally only been used for authentication when connecting to a new network as a way to eliminate potential fraud. Once the SIM is authenticated on the network, it normally goes dormant until instructed to run another function by the baseband or application processor. The interactions between these components are executed via the SIM Tool Kit (STK), which is a global standard that dates back to 2G networks and is supported by all standards-compliant SIMs and embedded cellular modules. SIMbae extends the SIM’s capabilities to act as a secure, independent processor by enabling the execution of user defined IoT tools and applications, effectively turning the tables in the device architecture to control the device’s connectivity and IoT functions.
SIMbae enhances the value and utility of the IoT device’s sunk SIM cost and integration by providing a standard, secure, low power, low touch, and easily deployed processor that can be securely updated remotely via standard OTA. SIMbae can execute IoT device connectivity QoE and security tools. Examples of this include SIMbae ensuring that a mobile credit card reader is always connected to the strongest signal and that data is working, or the updating of unique passwords for the applications of mass-produced devices that were shipped into the field. SIMbae can even host and execute the full IoT application, replacing the app CPU. This small applet’s patented innovation provides significant value by using standard, existing assets to address common mobile IoT challenges.
