Small controller that performs desired functionality (usually gathered data from a sensor), and is able to communicate with five RF remote base-station, or other end-station.
Challenges:
1. The unit must be a small size, low price and low power – working on a battery.
2. Maintain continuous RF connection with base-station.
3. Working with all common wire communication protocols like, SPI/I2C/UART.
Microcontroller that acts as a full local server, a small base-station that communicates with end-stations. The AP can be accessed as a local Wi-Fi device.
Challenges:
1. The unit must be a small size, low price and low power – working on a battery.
2. Implements full TCP stack.
3. Running RTOS (real-time operation system).
Microcontroller that is able to read/write data from/to SIM card. The device is very useful for backup and authentication purpose.
Challenges:
1. The unit must be a small size, low price and low power – working on a battery.
2. Using half-duplex APDU protocol.
3. Perform additional functionality as embedded system.
The following is an abstract to highlight the technical challenges of the project whilst not revealing confidential know-how information.
