Smart locks, smart
thermostats, smart cars — you’ve probably heard some of these terms lately, and
you’re going to hear them even more as the year goes on. But what are these
things exactly — and what makes them so smart?
These devices are all part of
an emerging category called the Internet of Things, or IoT for short. At its
very basic level, IoT refers to the connection of everyday objects to the
Internet and to one another, with the goal being to provide users with
smarter, more efficient experiences. Some recent examples of IoT products
include the Nest Protect smoke detector and August door locks.
But as with any new
technology, IoT can be confusing and intimidating for the average consumer,
especially as debates swirl around standardization, security and privacy, and
company after company piles on to this fast-growing trend. I’ve compiled an FAQ
on IoT to better explain how it works, how these products are being used in the
real world, and some of the issues and challenges facing the category.
I spoke with a number of
companies and groups working on IoT products and standards, including Apple,
Smart Things, the Internet of Things Consortium, All
Seen Alliance, the Open Interconnect Consortium and
the Thread
Group.
What exactly is the Internet of Things?
My colleague Walt Moss berg
gave a great, succinct overview of IoT when he described it this way: “The broad idea behind these
buzzwords is that a whole constellation of inanimate objects is being designed
with built-in wireless connectivity, so that they can be monitored, controlled
and linked over the Internet via a mobile app.”
The types of objects span a
wide range of categories, from wearable to light bulbs to home appliances
(like the coffee maker, washing machine, and even your car) — really, anything.
IoT is also being applied to vertical markets like the medical and health-care
industry and to transportation systems.
Okay, I think I get it, but
can you give me an example of how it’s being used today, and how does this
actually make things easier for me?
One of the better-known
examples is the Nest thermostat. This Wi-Fi-connected
thermostat allows you to remotely adjust the temperature via your mobile device
and also learns your behavioral patterns to create a temperature-setting
schedule.
The potential value is that
you can save money on your utility bill by being able to remotely turn off your
air conditioner, which you forgot to do before leaving the house. There’s also
a convenience factor. Nest can remember that you like to turn down the temperature
before going to bed, and can automatically do that for you at a set time.
Another company, Smart Things, which Samsung acquired in
August, offers various sensors and smart-home kits that can monitor things like
who is coming in and out of your house and can alert you to potential water
leaks, to give homeowners peace of mind.
As the IoT category expands
and the products become more sophisticated, one can envision a scenario where
your fitness tracker detects that you’ve fallen asleep and then automatically
turns off your TV and lights. Or, before hitting the road, your car could pull
up your work calendar and automatically provide the best route to your meeting,
or send a note to relevant parties if you’re running late.
On a broader scale, it is being used by cities to
monitor things like the number of available parking spaces, air and water
quality, and traffic.
How does IoT work?
I’ll try not to get too
technical here. First, there’s the underlying technology, the various wireless
radios that allow these devices to connect to the Internet and to each other.
These include more familiar standards like Wi-Fi, low-energy Bluetooth, NFC and
RFID, and some that you’ve probably haven’t heard of, like ZigBee, Z-Wave and 6LoWPAN (have your eyes glazed over yet?).
Then there are the things
themselves, whether they’re motion sensors, door locks or light bulbs. In some
cases, there may also be a central hub that allows different devices to connect
to one another.
Finally, there are cloud
services, which enable the collection and analysis of data so people can see
what’s going on and take action via their mobile apps.
What companies are working on
IoT?
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.
So, can all IoT devices talk
to each other?
This is where things get a little more
complicated. With so many companies working on different products, technologies
and platforms, making all these devices communicate with each other is no small
feat — seamless overall compatibility likely won’t happen.
Several
groups are working to create an open standard that would allow
interoperability among the various products. Among them are the All Seen
Alliance, whose members include Qualcomm, LG, Microsoft, Panasonic and Sony; and
the Open Interconnect Consortium, which has the support of Intel, Cisco, GE,
Samsung and HP.
While their end goal is the same, there are
some differences to overcome. For example, the OIC says the All Seen Alliance
doesn’t do enough in the areas of security and intellectual property
protection. The All Seen Alliance says that these issues have not been a problem
for its more than 110 members.

It’s not clear how the standards battle will
play out, though many believe we’ll end up with three to four different
standards rather than a single winner (think iOS and Android).
In the meantime, one way consumers can get
around the problem is by getting a hub that supports multiple wireless
technologies, such as the one offered by Smart Things.
These products seem to be
collecting a lot of data. Should I be worried about security and privacy?
The various amounts of data
collected by smart home devices, connected cars and wearables have many people
worried about the potential risk of personal data getting into the wrong hands.
The increased number of access points also poses a security risk.
The Federal Trade Commission
has expressed concerns, and has recommended
that companies take several precautions in order to protect their customers.
The FTC, however, doesn’t have the authority to enforce regulations on IoT
devices, so it’s unclear how many companies will heed its advice.
Of the companies I’ve talked
to, all said that security and privacy were of the utmost importance. For
example, Apple requires that companies developing products for its Home Kit
platform include end-to-end encryption and authentication and a privacy policy.
The company also said it doesn’t collect any customer data related to Home Kit
accessories.
