Machine Identification Modules (MIM)
M2M and IoT applications present new technology challenges, and in many cases, standard components designed for consumer devices are not ideally suited to the job. To meet the need for an M2M optimized SIM card that is ruggedized for long life in extreme conditions, a specialized platform was developed called the Machine Identification Module - MIM™ that has quickly become the preferred solution for enabling secure cellular connections.
MIMs are optimized to:
- Survive extremes of vibration, temperature, and humidity common to M2M applications
- Endure a long life span (ex: 10+ years)
- Occupy a small footprint (miniaturization)
- Withstand and integrate into industrial manufacturing processes
OTA (over the air)is a data-value-added service that enables users to obtain personalized information services by dynamically downloading, deleting, and updating the business menus in the SIM card through a mobile terminal or a server(online). OTA service (Over-the-Air Technology) is a technology face of mobile communication (GSM or CDMA).
The air interface can use WAP, GPRS, CDMAlX and SMS technology. Through the OTA download technology, mobile phone users can download various service menus provided by the network to the mobile phone according to personal preferences, and can also customize the specific service according to their own wishes.
