Terms and Acronyms¶
TI Wi-SUN FAN Stack Terms and Acronyms¶
- AES¶
Advanced Encryption Standard.
- BR¶
- Border router¶
Each Wi-SUN network contains a Border Router providing WAN connectivity to the PAN. The Border Router maintains source routing tables for all nodes within its PAN, provides node authentication and key management services, and disseminates PAN wide information such as broadcast schedules.
- GAK¶
- Group AES Key¶
All devices within a Wi-SUN FAN or PAN network use a common key called GAK for encrypting packets at MAC layer.
- GTK¶
- Group Transient Key¶
The GAK is derived from the Group Transient Key (GTK) which is installed on the node during the joining process. More info in Join Process.
- IEs¶
- Information elements¶
IEs allow hopping neighbors to transmit unicast messages to each other. IEs can be exchanged either during the joining of the network or during the network operation time.
- NCP¶
- Network co-processor¶
The TI Wi-SUN FAN network processor mode uses one host and one network co-processor with a UART interface.
- Root¶
In a Wi-SUN network, the border router is the root of the RPL tree.
- RPL¶
Routing protocol for low-power and lossy networks. See Routing Layer (RPL).
Sensor Controller Terms and Acronyms¶
- SC¶
- Sensor Controller¶
A dedicated 16-bit CPU core on CC13xx and CC26xx devices, located in the auxiliary (AUX) power/clock domain. It can perform simple background tasks autonomously and independently of the System CPU and the MCU domain power states.
- SCS¶

Over-the-Air Download (OAD) Terms and Acronyms¶
- BIM¶
- Boot Image Manager¶
A bootloader that runs after the device’s ROM startup code. The BIM is responsible for analyzing the image header of all images and determining the most suitable image to run. Once the BIM has found the proper image, it will jump to it’s program entry.
- CRC¶
- Cyclic Redundancy Check¶
An error-detecting code used to check the integrity of blocks of data.
- ECDSA¶
- Elliptic Curve Digital Signature Algorithm¶
A variant of the Digital Signature Algorithm (DSA) which uses elliptic curve cryptography.
- Factory Image¶
The factory image is a “golden” image that resides in external flash as a fail-safe mechanism.
- HIB¶
- Halt In Boot¶
A mechanism in CC13xx or CC26xx to ensure that the external emulator can take control of the device before it executes any application code.
- OAD¶
- Over-the-Air Download¶
The process of performing a device firmware update over the air.
- OAD Target¶
The device whose firmware is being upgraded over the air. This is assumed to be a CC26xx or CC13xx device running the TI protocol-specific transport for OAD.
- OAD Distributor¶
The device responsible for accepting an OAD enabled image from the compiler and transferring it over the air to the OAD Target.
General Terms and Acronyms¶
