In the first part, we discussed the purpose of the asset tracking system. In this part Ankur Gohel, IoT expert, Volansys Technologies is going to get in the details of the wireless protocol getting selected to create the Asset Tracking solution with the impacting parameters on selection. We will also talk about widely used industry applications and how it benefits the industry.
How to select the right wireless protocol for asset tracking system?
Wireless protocol selection plays a major role in the entire asset tracking system designing. The selection of the protocol will entirely depend on the type of industrial applications to be designed. Depending upon the protocol selection, the type of tag, router, hub and other infrastructure related to cloud and app are required accordingly.
Here are some of the Personal Area Network protocol (PAN) for utilising for short effective range application up to 100mtr: BLE, Zigbee, Z-wave, and Wi-Fi and some of the Wide Area Network (WAN) protocols are Wi-Fi, LTE Cellular, LPWA (LoRaWAN, NB-IoT, Sigfox, and more.) which can provide effective application range up too few Kilometers. Following are the critical parameter for the selection of the wireless protocol requirement to make it affordable, scalable and efficient according to industry needs.

Widely accepted IoT based asset tracking industry applications:
Any industry application that requires improvement in workflow, loss prevention of assets, service quality and productivity, would prefer to implement these kinds of tracking solutions. Depending on budget and ROI of the solution, the customer would choose between traditional RFID solution and latest IoT based asset tracking solution. Here we will be focusing on some of the critical IoT based Asset tracking solutions successfully implemented in various industries and helped those industries to improve tremendously.
Based on the application requirement is indoor or outdoor there will be many structural changes at the solution designing level. For example, for outdoor applications GPS can give location with acceptable accuracy but when we need to identify the location in the locality in the building where the GPS signal is not good at that time, we must use special BLE functions like Angle of Arrival (AOA) and Angle of Departure (AOD) to identify the location of the device. AoA and AoD are different techniques.
In AoD, the receiving device can calculate its own position in space using angles from multiple beacons and their positions (by triangulation). In AoA, the receiving device tracks arrival angles for individual objects. Using these technologies, we can get 0.5 m location accuracy even for indoor application. This kind of improvisation can be useful in many such following industry applications.
Manufacturing industry (Smart manufacturing management, smart inventory management)
Manufacturing automation is one of the key aspects of today’s manufacturing processes optimisation. Starting from raw material to final products, the asset is tracked at each stage to build a more efficient and productive system. Apart from the traditional asset tracking solutions using [...]
