@Aurora0001 Yes, they're saying that android does expose the feature - which confirms that what I propose in my answer is 'possible'. Not a good answer, but not completely off base.

Guys wanted to ask whether as an application field does IoT heavily rely on wireless technology? Is it the main selling point?
on the contrary, data acquisition and sensor technology fields have been around for quite a while and integrating them with a wireless device for communication within other entities and the end user somehow makes it a thing

@Shan-Desai I don't think that is a good way to look at it.
none of the elements of IoT are particularly new. What is new is the availability of country-wide data transports, and the ability to deploy sensors cheaply.
So the fact that a sensor node (supporting end-to-end encryption) can be made for a few $ is just as important at the ability to connect it.
smartcambridge.org has deployed a network (costing maybe £10k), with a range of 10-20km covering both the city and the surrounding area. They're now talking about installing many hundreds of air quality sensors, trafic flow, people counting, bin-remaing-capacity sensors.
With this data, they expect to be able to influence both planning and automation. (and demonstrate the impact of for example switching the flow-bias of a set of traffic lights).
None of this requires wireless technology, but it does require being able to install sensors at an annual cost that is justified by the value add (where in-field battery replacement probably costs as much as a sensor).
The main selling point is the collect/analyse/adapt feedback loop. Be this optimising traffic flow, timing the deployment of fertiliser and harvesting of crops or whatever.

@SeanHoulihane That is quite an interesting point. Thanks Sean.
But what about participating vehicles like buses etc. will they need wireless sensors to send data back and forth towards a central point.

@Shan-Desai yes, wireless sensors are used, but for the busses, I would expect they use a cheap android phone as the sensor (GPS and GSM build in). Ubiquitous wireless lowers the barriers to deploying a network, but 20 years ago we'd have implemented something different (optical, or inductive coupling on the bus-stops maybe).

If you want to call out wireless, it's license free wireless that makes the difference. I built the RF part of a remote electric/gas meter reading system in about 1999. We had a license allocated 100kHz in the 183.5 to 184.5 MHz band (and needed to build a custom transmit/receive system).

Q: What is the difference between a DDoS attack and a PDoS attack?

anonymous2I've read a certain amount about the Mirai worm, a virus that attacks Internet of Things devices using default usernames and passwords and essentially is wired to produce a Distributed Denial of Service (DDoS). However, I've recently read about another worm, BrickerBot, also a virus attack on In...

Q: Is it legal if I'm managing my family's entire wealth?

AnoneemusMy family (father, mother, and brother) have allowed me to invest their money in the stock market and other types of investments (real estate, bonds and mutual funds). Is it legally okay to do all the investments under my name? Which means that I transfer all their funds to my bank account and ...

@Ghanima The motto of virtually every HNQ?

"Why Would Aliens Enslave Humans?"

You get the picture :P
