Introduction

TI 15.4-Stack

TI’s royalty-free TI 15.4-Stack is a complete software platform for developing applications that require extremely low-power, long-range, reliable, robust and secure wireless star-topology-based networking solutions. TI 15.4-Stack is a wireless stack component of the SimpleLink™ MCU platform that implements the standard IEEE 802.15.4e and 802.15.4g specification. For Sub-1 GHz frequencies TI 15.4-Stack also implements a frequency-hopping scheme adopted from Wi-SUN® field area network (FAN) specification. This SDK also provides the required tools, real-time operating system (RTOS), and example applications for TI 15.4-Stack to help developers quickly get started developing their own star-topology-based wireless network products. The purpose of this document is to give an overview of TI 15.4-Stack to help developers run the out-of-box example applications and enable creation of custom TI 15.4-Stack based wireless star-topology networking solutions. This document introduces the essential need-to-know technology details for developing a wireless network based on the IEEE™ 802.15.4 and Wi-SUN FAN specification supported by TI 15.4-Stack.

Attention

Do not use this document as a substitute for the complete specification. For more details, see the IEEE 802.15.4 specification and Wi-SUN FAN specification.

IEEE 802.15.4

The Institute of Electrical and Electronics Engineers (IEEE) 802.15.4 standard defines the physical (PHY) and media access control (MAC) layers of the Open Systems Interconnection (OSI) model of network operations. The PHY defines the wireless link conditions like modulation, frequency, and power, while the MAC defines the format of the data.

TI implementation of this standard combines the following:

  • The basic standard (802.15.4-2006) with the most recent updates

  • The 802.15.4e for industrial applications and 802.15.4g for the smart utility networks (SUN)

  • An implementation of Wi-SUN frequency hopping
