Wi-Fi – “the toy that grew up”

Wi-Fi – “the toy that grew up”

Historically, Mobile Network Operators (MNOs) looked at Wi-Fi as a toy, a low-end technology that was great to off-load data from networks. Now Wi-Fi is having a strategic impact on MNOs across the globe. Now the question is LTE or Wi-Fi: remind me which one’s for off-load?

Yet, as with many technical innovations, the low-end always wins. Wi-Fi is a classic example of this theory. Through a combination of Moore’s Law, economies of scale, R&D investments and free market dynamics Wi-Fi is king of the hill. In most developed countries people and things can access a Wi-Fi network in 80% of locations. Companies, such as Devicescape, have created virtual networks based on “ambient’ Wi-Fi networks. Hotspots are so ubiquitous that Opensignal launched an application to find the best one out of the many available.

Wi-Fi and Hotspots are becoming strategic to all carriers (fixed and mobile) as they have realized the importance of keeping traffic on their network for quality of experience and billing purposes. The market for carrier Wi-Fi gear continues to grow as carriers look to exploit these opportunities.

Today, high- speed access to the Internet is as fundamental as indoor plumbing. People expect it and city and national governments view it as mandatory for many economic development and quality of life issues. With the ubiquity of Wi-Fi enabled devices and the simplicity of Wi-Fi deployments it is no surprise that Wi-Fi is a leading candidate to achieve this. Even in remote,rural and under-developed regions, Wi-Fi leads the ways.

Even with fierce competition from ZigBee and other alternatives Wi-Fi is also a leading network technology for applications using IoT technologies. Wearables are no exception. LG smart watches use Wi-Fi and researchers are looking to Wi-Fi for an entire body network. We could all become Wi-Fi access points.

Yet success breeds challenges. Wi-Fi uses attractive unlicensed frequency bands and the licensed crowd wants in as the LTE community is looking to use the same 5 Ghz frequency band. Trying to head off a battle royale, the U.S. FCC has already entered the fray.

Wi-Fi, the toy that grew up, continues its momentum to solve real problems for consumers, businesses, service providers and governments. It was often said never to bet against Ethernet, I’d like to add never bet against Wi-Fi.

Does Anyone Doubt IoT is at the Peak of the Hype Curve?

Yikes!  That's all I need to say about the excessive hype of anything and everything IoT these days.  From the connected refrigerator, the connected car, wearables, et al the hype in this market is out of control.  Every industry leader from Cisco, Microsoft, Intel, Facebook, Google, Apple, Amazon is staking their claim as the industry thought leader.  The same is true for hundreds of smaller companies.  The only thing clear is that IoT is at the peak of the hype curve.

M2M (Machine-to-Machine) applications have been around for decades and have been and are quite successful.  Many are based on industry standard protocols and millions of "things" are connected via the cellular network.  Nothing new here.  Remote sensors connected via some network to a centralized location where the sensor's data is aggregate, analyzed and acted upon.

Once the hype "bubble" crashes many real markets will be widely successful.  You will know what markets they are since they will not include the acronym IoT in their description.

IoT Success: Batteries & Backhaul...& Transparency

The Internet of Things (IoT) is riding high at the peak of the Hype Cycle.  Is it a $17 Trillion market or merely a $10 Trillion market?  Depends on what you include in your definition of a "thing".  The more you include the bigger the market.  

IoT applications have a basic common architecture as shown in Figure 1. IoT digitizes some analog parameter and sends it to the "cloud" for analysis and possible action.   The primary factors that all IoT or M2M applications must address are Batteries, Backhaul and Transparency.   

Let's address the transparency issue first.  In quantum physics there's the "uncertainty principle".  Simply put is says that whenever you measure a system you disturb it.  Since most IoT applications measure a real world analog phenomena (e.g., temperature, pressures, et al) the "thing" must do so with minimal impact on the system you are measuring.   Transparency parameters include cost (CAPEX and OPEX), size, weight, aesthetics etc. 

Batteries, or more generally power, is a critical parameter within IoT applications.  If you require grid power you lose some transparency and limit your ability to deploy the thing.  Not every location will be close enough to the grid to be able to be powered by it.  Remote sensors will require batteries.  These batteries must last many months and even many years.  

Even IoT applications within the home must address the battery issue.  Take a simple motion detector.  The ideal placement is in the corner of the room near the ceiling.  Not many power outlets near by.  Thus the customer can either install an outlet close by, move the sensor close to the outlet (i.e., near the floor) or have to see the wire dropping down to the nearest outlet.  Batteries solve this problem.  However, if they need to be replaced every month the value and transparency quickly depreciates.  What if this motion detector is part of a security perimeter for a high value asset (e.g., power plant).  If the good guys need to replace the batteries periodically it will show the bad guys where these "hidden" sensors are.  Thus, batteries are critical to the success of the application and can make or break a business case.  

The "I" in "IoT" is for "Internet", meaning internet protocols (IP).  The digital data of the analog phenomena must be sent to the cloud via some type of network. This is referred to as Backhaul.  Networking options are plentiful  and include 2G/3G/4G/LTE, Wi-Fi, Zig-Bee, Satellite, Blue Tooth, Ethernet and local broadband options.  The technology selected depends on the application and on parameters such as data rates, latency, cost and what's available.  The more remote the thing is the less options are likely available.  The selection of a backhaul solution must address both transparency and battery issues discussed above.  

There are other issues and parameters that need to be address to make an IoT application successful.  For example, the cloud solution (e.g., "big data" base, analytics, heuristics, et al) are not trivial yet they are solvable engineering problems.  The same is true for the "thing" or sensor. For most all you have to do is go to the Analog Device catalog and select a chip.  Again, non trivial but solvable.  Thus, batteries and backhaul and transparency are critical make-or-break parameters to ensure success of your IoT application.

IoT? Internet of Things....What is a Thing?

Internet of Things, or IoT, is a topical conversation these days.  Companies with vested interest, such as Cisco, have announced this market to be $Billions and $Billions in the not so distant future.  

The word “thing” is a good one here.  You can add “no” and “every” to the front of it and get other proper words.  So IoT can mean “nothing” and “everything”.   That exactly what it means today! 

A market of nothing and everything is not a real market.  It’s either a ZERO billion dollar market (nothing) or an infinite billion dollar market (Everything).   Zero dollar markets don’t sell market research reports and space at trade shows.  So the industry tends to favor the infinite dollar market.  So we see reports of IoT being a $19 TRILLION market (Cisco), $14 to $33 Trillion (Mckinsey) and a mere $2 Trillion market (Gartner). 

We’ve seen this movie before.  In the 1990’s the market for “Multimedia” was predicted to be many billions and more recently we hear the market for “Cleantech” will be multiple billions.  Yet, like the term IoT, these words meant nothing and everything. 

When asked what multimedia applications were the answers were always video editing, video conferencing, training and kiosk.   Not sure about “kiosk” but the other three are not multimedia applications they are specific identifiable markets.

Similarly, what are cleantech applications?  Energy efficiency, renewable energy and smart grid are often the answer.  Here again, these are not cleantech applications, they are specific identifiable markets. 

So let’s drop the hype around IoT and start talking about real markets that combine sensors, IP networks and analytics.  I almost said “Big data”, but that’s another “nothing” and “everything” market.
