Bluetooth® Mesh Networking: Bluetooth Low Energy[BLE] Mesh networks enables several BLE devices to be connected to each other in Mesh. Therefore, even if a node is out of range, it can be reached using hops using intermediate devices. All compatible smartphones currently on the market can connect to objects in Bluetooth mesh networks directly without requiring a central gateway or router. It allows easier control of smart lighting, general building automation and other Internet of Things (IoT) applications, such as environmental sensing, industrial monitoring and asset tracking.

STSW-BNRG-Mesh is our first software pack enabling developers to create Bluetooth mesh solutions. It works in conjunction with the BlueNRGMesh apps for iOS and Android, which is highly symbolic since it’s the first time someone ports Bluetooth mesh libraries to these operating systems. The new standard, introduced in 2017, uses Bluetooth Low Energy (LE) to create a mesh network of up to 32,000 devices. It compares in some ways to 6LoWPAN as data travels the mesh to reach a gateway with a connection to the Internet. We ensured that the creation of a 6LoWPAN network would be straightforward, and we are now doing the same with Bluetooth mesh. Furthermore, our BlueNRG–1 and BlueNRG–2 Systems-on-Chip (SoC), the SPBTLE–1S ready-to use Bluetooth LE module, and BlueNRG-MS (with at least an STM32L152RE as host) just need a firmware update to take advantage of this new technology.

What are the other applications of STCOMET other than smart metering and smart grid?

STCOMET-Evaluation-kitSapna Mongia: STCOMET is the industry’s first super-integrated complete smart-meter System on-Chip (SoC). It combines a precision metering front-end with programmable application processing and multi-standard PLC (Power-Line Communication) subsystems along with a line driver and advanced security engine in a single device. The STCOMET10 SoC delivers unprecedented integration, leveraging ST’s expertise gained over 20 years and through more than 60 million PLC and smart-meter ICs delivered.

STCOMET caters multiple applications as it is powerline communication platform and now it can be used for multiple aspects. For example, for metering if you have a meter outside your house but you want to see the display inside the house. So you just put a display and you put it in any plug of your house. Because meter and the plug are connected by the same power line so you will start to see the meter reading. And networking within your home irrespective of your meter, you can control anything from anywhere from the room. You can do the same thing with PLC also that runs on NFC powerline communication because now if you’re communicating on powerline which is present in all of the house you can control the light of any room from anywhere, you can take the readings of the individual devices and you can take all those reading at one place


How semiconductor industry is affected by IoT?

Vishal Goyal: IoT industry is booming, almost every company is adopting this technology whether it is smart personal things, smart home, smart Industry or smart cities. These booming requirements has positively influenced need of semiconductors. The level of content of semiconductors has increased a lot. The IoT creates the need for semiconductors delivering embedded intelligence, connectivity, data security and smart power – all of which are focus areas for ST. Our portfolio allows us to deliver complete solutions to meet these needs.

Let’s take an example of LED bulb, it is a simple bulb, but if the bulb becomes smart it will have connectivity in it and requires more sensors. So more requirements from the devices is coming to us. So IOT has a very positive impact on our company and it will be one of the key growth drivers for our company.

Please explain about your Smart Parking solutions demo.

smart-parking-demoVishal Goyal: Smart Parking is becoming a reality now. Smart parking solution is based on LPWAN technology called SIGFOX. These are the two state-of-the-art technologies from us. Low power consumption is a strong requirement for almost 80% of the Low-Power Wide-Area Network (LPWAN)-based use cases, ranging from Smart Parking solutions to Smart Grid applications. These services often demand wide communication coverage with massive connection availability LPWAN technologies has a clear potential in the wireless market, as they are capable of providing connections to large number of IoT devices. These communication modules are embedded along with the sensors, which transmit the occupancy status of the parking spots, providing the necessary inputs to calculate the available parking opportunities in a certain area. The sensor information is wirelessly transferred to a Sigfoxgateway which finally forwards to parking management server and eventually to the User Mobile App.

What has triggered the current popularity of Smart Grid as a concept in India?

Smart-Grid-demoSapna Mongia: Smart Grid in India is becoming the key application in Indian power sector. Smart meters will help to overcome the challenges in the power sector as they will enable utilities to access energy consumption data from remote without manually reading the meter. It will help in managing the power supply distribution from remote and it will benefit the consumers to monitor and reduce their power consumption remotely as it will provide real time accurate power consumption data. This data can be accessed frequently as required and also available in the consumer premises on In-Home display unit. So the communication feature of the smart meter provides the utility to manage power load and reduce losses. Depending on the load requirement and by constant monitoring of the load of a particular area, the utilities can implement the different tariff plan for that area to manage peak hour’s demands. Also

Smart meters will help to check the theft, power pilferage and monitor the quality of power supplied to the consumers ST has major programs in place to support the smart-grid concept where semiconductor technology will play a critical role. Our products find application in (a) smart metering, (b) building automation, (c) PHEVs (plug-in hybrid electric vehicles) and (d) renewable energy sources.
