Medical devices, which can be wearable or nonwearable, or even implantable, injectable, or ingestible, can permit remote tracking of a patient’s vital signs, chronic conditions, or other indicators of health and wellness.36 Wireless medical devices may be used not only in hospital settings but also in remote monitoring and care, freeing patients from sustained or recurring hospital visits. Some experts have stated that advances in healthcare IoT applications will be important for providing affordable, quality care to the aging U.S. population.


39).What are the main Social and Cultural Impacts of Internet Of Things (IoT)?

Ans) The IoT may create webs of connections that will fundamentally transform the way people and things interact with each other. The emerging cyberspace platform created by the IoT and SMAC has been described as potentially making cities like “computers” in open air, where citizens engage with the city “in a real-time and ongoing loop of information.”

Some observers have proposed that the growth of IoT will result in a hyperconnected world in which the seamless integration of objects and people will cause the Internet to disappear as a separate phenomenon. In such a world, cyberspace and human space would seem to effectively merge into a single environment, with unpredictable but potentially substantial societal and cultural impacts.


40).Will IoT actually work over the internet or will it have its own dedicated wide area network?

Ans)Interoperability between various wireless and networking standards is still an issue and something that forums and standards bodies are trying to address. According to Franks, businesses have to collaborate on standards to create strong ecosystems for a range of industries, otherwise the industry will remain fragmented.

“The IoT is a whole myriad of different ways of connecting things ? it could be fixed, Wi-Fi NFC, cellular, ultra-narrow band or even Zigbee. You have to mix and match what is best for each task,” he says. “Interoperability is essential, for economies of scale.”


41).What are the important Components of Internet of Things?

Ans)Many people mistakenly think of IoT as an independent technology. Interestingly, internet of things is being enabled by the presence of other independent technologies which make fundamental components of IoT.

The fundamental components that make internet of things a reality are:-

  1. Hardware-Making physical objects responsive and giving them capability to retrieve data and respond to instructions
  2. Software – Enabling the data collection, storage, processing, manipulating and instructing
  3. Communication Infrastructure – Most important of all is the communication infrastructure which consists of protocols and technologies which enable two physical objects to exchange data.

42).What are the main Challenges of Internet of Things (IoT)?

Ans)Like any other technology there are challenges which make the viability of IoT doubtful.

Security is one of the major concerns of experts who believe virtually endless connected devices and information sharing can severely compromise one?s security and well being. Unlike other hacking episodes which compromise online data and privacy with IoT devices can open gateway for an entire network to be hacked.

One such flaw is well presented by Andy Greenberg on wired.com where he works with hackers to remotely kill his Jeep on the highway. Another very relevant example is provided by W. David Stephenson in his post Amazon Echo: is it the smart home Trojan Horse? You can estimate the amount of personal and private data the connected devices will be producing once they are on a network. The major challenge for IoT tech companies is to figure out how the communication in the internet of things realm can be made truly secure.


43).What is the Internet of Everything?

Ans)The Internet of Everything is the intelligent connection of people, process, data and things.

44).What is a “Thing” in the context of Internet of Things (IoT)?

Ans) The “Thing” commonly referred to by the concept of the Internet of Things is any item that can contain an embedded, connected computing device. A “Thing” in the IoT could be a shipping container with an RFID tag or a consumer’s watch with a WiFi chip that sends fitness data or short messages to a server somewhere on the Internet.


45).How the Internet of Things (IoT) makes a difference to the businesses?

Ans)Businesses focus on getting products to the marketplace faster, adapting to regulatory requirements, increasing efficiency, and most importantly, persisting to innovate. With a highly mobile workforce, evolving customer, and changing supply chain demand, the IoT can move your enterprise forward, starting today.


46).What is Bluetooth Low Energy (BLE) Protocol for Internet of Things (IoT)?

Ans)Nokia originally introduced this protocol as Wibree in 2006. Also known as Bluetooth Smart this protocol provides the same range coverage with much reduced power consumption as the original Bluetooth. It has similar bandwidth with narrow spacing as used by ZigBee. Low power latency and lower complexity makes BLE more suitable to incorporate into low cost microcontrollers.

Low power latency and lower complexity makes BLE more suitable to incorporate into low cost microcontrollers.

As far as application is concerned BLE is in healthcare sector. As wearable health monitors are becoming prevalent the sensors of these devices can easily communicate with a smart phone or any medical instrument regularly using BLE protocol.


47).Why is the Internet of Everything happening now?

Ans)The explosion of new connections joining the Internet of Everything is driven by the development of IP-enabled devices, the increase in global broadband availability and the advent of IPv6.


48).What are the top 5 Machine-to-Machine (M2M) applications in the world?

Ans)

  1. Asset Tracking and/or Monitoring in some form or another (Stolen Vehicles, Fleet, Construction Equipment, Wood Pellets, Tank level monitoring, etc.) seems to be the biggest. Low data requirements, high volumes of devices, etc. It isn’t hot or particularly exciting, but it is changing the world in subtle ways and very quickly. New business models will spring from this.
  2. Insurance Telematics is huge as if offers Insurance companies the opportunity to cut risk and drive better/more attractive pricing.
  3. Utilities/Automated Meter Reading/Smart Grids – lots of regulation and investment into this at the moment. There a lots of national solutions as the requirements and business case are driven in very diverse ways.
  4. Security has been an early adopter here. The requirements are quite heavy on the network as many of these applications have a fixed line legacy.
  5. mHealth has been out there for a while, but hasn’t really taken off. There are some exciting early adopters. Many of the established companies (largely built through acquisition) have some challenges moving quickly in this space, but when they get up to speed and the business models are established there will be a massive uptake.
  6. Automotive is a big one – driven by consumers’ expectation of being always connected as well as regulation.

49).What impacts will the Internet of Things (IoT) have on Transportation Sector?

Ans)Transportation systems are becoming increasingly connected. New motor vehicles are equipped with features such as global positioning systems (GPS) and in-vehicle entertainment, as well as advanced driver assistance systems (ADAS), which utilize sensors in the vehicle to assist the driver, for example with parking and emergency braking. Further connection of vehicle systems enables fully autonomous or self-driving automobiles, which are predicted to be commercialized in the next 5-20 years.

Additionally, IoT technologies can allow vehicles within and across modes?including cars, buses, trains, airplanes, and unmanned aerial vehicles (drones) to “talk” to one another and to components of the IoT infrastructure, creating intelligent transportation systems (ITS). Potential benefits of ITS may include increased safety and collision avoidance, optimized traffic flows, and energy savings, among others.


50).What companies are working on Internet of Things (IoT)?

Ans)At this point, the easier question might be who isn?t working on an IoT product. Big names like Samsung, LG, Apple, Google, Lowe?s and Philips are all working on connected devices, as are many smaller companies and startups. Research group Gartner predicts that 4.9 billion connected devices will be in use this year, and the number will reach 25 billion by 2020.
