How To identify right Industrial IoT Platforms
As per proprietary research by BCC research the Global IoT market is set to gain by $37 Billion by 2021. The research is focused on the endpoints particularly sensors as they are the critical start point for the IoT communications. But the data collection platform is another decisive parameter in the IoT eco-system. This article will focus on How To identify right Industrial IoT Platforms and cover critical parameters which should be taken into account when identifying the right electronics hardware platform. There are plethora of evaluation boards, modules, chip-sets hence it is important that all the requirements are taken into account and the platforms are chosen wisely as per the actual deployment and customer specific requirements.
Understanding the requirement
First step in identifying right Industrial IoT Platforms is to understand the requirements in terms of various parameters. Below are few guidelines questions which should be asked to customers to get the right Industrial IoT Platforms requirement of the platform.
- How many Sensors to be supported? Which in turn will give idea about GPIO lines.
- Computing Power
- Memory requirements
- Is it node or gateway ?
- IoT node requirements are low power, long battery life
- IoT gateway requirements –
- Interfaces Required (Ethernet, WiFi, BT, Zigbee, Zwave, Sigfox, LoRa)
- Location – Outdoor, Indoor
Comparison of various embedded platforms
Below are some of the platforms features comparisons which can help the product designer and customers alike on understanding How To identify right Industrial IoT Platforms for their applications.
