# I3 Mote: An Open Development Platform for the Intelligent Industrial Internet
## 7 Discussion  
The use of wireless deterministic technologies such as 6 TiSCH is gradually being understood and adopted by industries to complement existing sensing infrastructures (usually wired). Wireless communications provide lower operating costs by reducing wiring and driving needs. This results in simple, non-intrusive deployment, thereby reducing operational requirements and minimizing training efforts as networks are self-organizing. The increased demand for these technologies from an application perspective, the recent advances on low power radio and microncontrollers and the consolidation of low-power wireless standards targeting industrial requirements has accelerated the development of novel wireless-enabled products.  
The I3 Mote is positioned as a development platform between pure prototyping and the a final product. This aims to address an early demand of such a technology and enable software customization exploiting general-purpose functionalities of the designed device. With the I3 Mote we facilitate product development promoting platform-based design as we believe that the bottom-line requirements for most of the use cases are similar. In this line, we have understood that support for a wide range of sensing devices, including legacy industrial buses, powerful computing capabilities for embedded data fusion and ultra-low-power wireless communication interfaces are key corner stones to support any future-proof industrial device.  
The I3 Mote ecosystem is designed to support quick industrial adoption in industrial automation and control scenarios possibly where industrial sensors need to be interfaced and data extracted reliably to the Internet. The device ecosystem aims to facilitate product development by providing license-free software, toolchain and examples. The open licensing of the software, hardware and tools contribute to the democratization of its design enabling industries to reuse most suitable parts to tailor the design in order to obtain cost-effective products.  
The future direction we take will complement the ecosystem with a new I3 Mote hardware, addressing other industrial demands such as serial buses with RS485, providing ModBus support and enabling longer range connectivity through subGhz radio interfaces.
