Cellular IoT (CIoT) or LoRa?

Back in September, 3GPP reached a decision to standardise NarrowBand IOT (NB-IOT). Now people familiar with the evolution of LTE-A UE categories may be a bit surprised with this. Upto Release-11, the lowest data rate device was UE Cat-1, which could do 10Mbps in DL and 5Mbps in UL. This was power hungry and not really that useful for low data rate sensor devices. Then we got Cat-0 as part of Release-12 which simplified the design and have 1Mbps in DL & UL.

Things start to become a bit complex in Release-13. The above picture from Qualcomm explains the evolution and use cases very well. However, to put more details to the above picture, here is some details from the 4G Americas whitepaper (embedded below)


In support of IoT, 3GPP has been working on all several related solutions and generating an abundance of LTE-based and GSM-based proposals. As a consequence, 3GPP has been developing three different cellular IoT standard- solutions in Release-13:
  • LTE-M, based on LTE evolution
  • EC-GSM, a narrowband solution based on GSM evolution, and
  • NB-LTE, a narrowband cellular IoT solution, also known as Clean Slate technologies
However, in October 2015, the 3GPP RAN body mutually agreed to study the combination of the two different narrowband IoT technical solutions, EC-GSM and NB-LTE, for standardization as a single NB-IoT technology until the December 2015 timeframe. This is in consideration of the need to support different operation modes and avoid divided industry support for two different technical solutions. It has been agreed that NB-IoT would support three modes of operation as follows:
  • ‘Stand-alone operation’ utilizing, for example, the spectrum currently being used by GERAN systems as a replacement of one or more GSM carriers,
  • ‘Guard band operation’ utilizing the unused resource blocks within a LTE carrier’s guard-band, and
  • ‘In-band operation’ utilizing resource blocks within a normal LTE carrier.

Following is a brief description of the various standard solutions being developed at 3GPP by October 2015:

LTE-M: 3GPP RAN is developing LTE-Machine-to-Machine (LTE-M) specifications for supporting LTE-based low cost CIoT in Rel-12 (Low-Cost MTC) with further enhancements planned for Rel-13 (LTE eMTC). LTE-M supports data rates of up to 1 Mbps with lower device cost and power consumption and enhanced coverage and capacity on the existing LTE carrier.

EC-GSM: In the 3GPP GERAN #62 study item “Cellular System Support for Ultra Low Complexity and Low Throughput Internet of Things”, narrowband (200 kHz) CIoT solutions for migration of existing GSM carriers sought to enhance coverage by 20 dB compared to legacy GPRS, and achieve a ten year battery life for devices that were also cost efficient. Performance objectives included improved indoor coverage, support for massive numbers of low-throughput devices, reduced device complexity, improved power efficiency and latency. Extended Coverage GSM (EC-GSM) was fully compliant with all five performance objectives according to the August 2015 TSG GERAN #67 meeting report. GERAN will continue with EC-GSM as a work item within GERAN with the expectation that standards will be frozen by March 2016. This solution necessarily requires a GSM network.

NB-LTE: In August 2015, work began in 3GPP RAN Rel-13 on a new narrowband radio access solution also termed as Clean Slate CIoT. The Clean Slate approach covers the Narrowband Cellular IoT (NB-CIoT), which was the only one of six proposed Clean Slate technologies compliant against a set of performance objectives (as noted previously) in the TSG GERAN #67 meeting report and will be part of Rel-13 to be frozen in March 2016. Also contending in the standards is Narrowband LTE Evolution (NB-LTE) which has the advantage of easy deployment across existing LTE networks.

Rel-12 introduces important improvements for M2M like lower device cost and longer battery life. Further improvements for M2M are envisioned in Rel-13 such as enhanced coverage, lower device cost and longer battery life. The narrowband CIoT solutions also aim to provide lower cost and device power consumption and better coverage; however, they will also have reduced data rates. NB CleanSlate CIoT is expected to support data rates of 160bps with extended coverage.

Table 7.1 provides some comparison of the three options to be standardized, as well as the 5G option, and shows when each release is expected to be finalized.

Another IoT technology that has been giving the cellular IoT industry run for money is the LoRa alliance. I blogged about LoRa in May and it has been a very popular post. A extract from a recent article from Rethink Research as follows:

In the past few weeks, the announcements have been ramping up. Semtech (the creator of the LoRa protocol itself, and the key IP owner) has been most active, announcing that The Lace Company, a wireless operator, has deployed LoRa network architecture in over a dozen Russian cities, claiming to cover 30m people over 9,000km2. Lace is currently aiming at building out Russian coverage, but will be able to communicate to other LoRa devices over the LoRa cloud, as the messages are managed on cloud servers once they have been transmitted from end-device to base unit via LoRaWAN.

“Our network allows the user to connect to an unlimited number of smart sensors,” said Igor Shirokov, CEO of Lace Ltd. “We are providing connectivity to any device that supports the open LoRaWAN standard. Any third party company can create new businesses and services in IoT and M2M market based on our network and the LoRaWAN protocol.”

Elsewhere, Saudi Arabian telco Du has launched a test LoRa network in Dubai, as part of a smart city test project. “This is a defining moment in the UAE’s smart city transformation,” said Carlos Domingo, senior executive officer at Du. “We need a new breed of sensor friendly network to establish the smart city ecosystem. Thanks to Du, this capability now exists in the UAE Today we’ve shown how our network capabilities and digital know-how can deliver the smart city ecosystem Dubai needs. We will not stop in Dubai; our deployment will continue country-wide throughout the UAE.”

But the biggest recent LoRa news is that Orange has committed itself to a national French network rollout, following an investment in key LoRa player Actility. Orange has previously trialed a LoRa network in Grenoble, and has said that it opted for LoRa over Sigfox thanks to its more open ecosystem – although it’s worth clarifying here that Semtech still gets a royalty on every LoRa chip that’s made, and will continue to do so until it chooses not to or instead donates the IP to the non-profit LoRa Alliance itself.

It would be interesting to see if this LoRa vs CIoT ends up the same way as WiMAX vs LTE or not.

Embedded below is the 4G Americas whitepaper as well as a LoRa presentation from Semtech:

Some interesting presentations from ETSI Security workshop


ETSI held their security week from 22-26 June 2015 at their headquarters. There are lots of interesting presentations (see agenda [PDF]); I am embedding some here.


This is a good presentation providing a summary of the reasons for IoT security issues and some of the vulnerabilities that have been seen as a result of that.




The next one is The Threat landscape of connected vehicles and ITS (Intelligent Transportation Systems) integration in general



This presentation provides a good summary of the threats in the connected cars/vehicles which is only going to become more common. Some of these issues will have to be solved now before we move on to the autonomous vehicles in future. Security issues there will be catastrophic and many lives can be lost.

The final presentation is from 3GPP SA3 that provides a quick summary of security related work in 3GPP.

A tale of two Smart Cities

Over the last few months I heard quite a few talks about Smart Cities. Here are two that I thought its worth posting and a very good TEDx talk at the bottom



I think we all agree that more and more people will move from rural to urban areas and the cities will not only grow in population but also in size. The infrastructure will have to grow to be able to cope with the influx of people and increased demand on services.



I guess in most developed nations we have the 1.0 Era Digital City which is long way away from the 3.0 Era Smart City.



To be a full fledged 3.0 Smart City, every aspect of our life may need to evolve into "Smart". Anyway, here is the complete presentation:





While IoT would be important, access, big data, applications, etc. all will have a role to play.



If you want to find out more about the Milton Keynes smart city, also see this video on Youtube. There are driverless pods and other autonomous cars which may be considered as initial step towards smart cities, see this interesting video here.

Finally here is the TEDx talk about designing these smart cities for future:

LTE-M a.k.a. Rel-13 Cellular IoT

Some months back I wrote about the LTE Category-0 devices here. While Rel-12 LTE Cat 0 devices are a first step in the right direction, they are not enough for small sensor type of devices where long battery life is extremely important. As can be seen in the picture above, this will represent a huge market in 2025.


To cater for this requirement of extremely long battery life, it is proposed that Rel-13 does certain modifications for these low throughput sensor type devices. The main modification would be that the devices will work in 1.4MHz bandwidth only, regardless of the bandwidth of the cell. The UE transmit power will be max of 20dB and the throughput would be further reduced to a maximum of 200kbps.

The presentation, from Cambridge Wireless Future of Wireless International Conference is embedded below:

Smart Homes of the Future and Technologies


Saw the above picture recently on Twitter. While its great to see how connected our future homes and even cities would be, it would be interesting to see what technologies are used for connecting these devices.

Cambridge Wireless had a smart homes event last month, there were some interesting presentations that I have detailed below.


The first of these technologies discussed is LoRa. As can be seen, its billed as ultimate long range (10 mile) and low power (10 year battery lifetime) technology. It uses spread-spectrum making it robust to channel noise. Here is the presentation:




The next technology is Zigbee 3.0. According to Zigbee Alliance:

The new standard unifies ZigBee standards found in tens of millions of devices delivering benefits to consumers today. The ZigBee 3.0 standard enables communication and interoperability among devices for home automation, connected lighting, energy efficiency and other markets so more diverse, fully interoperable solutions can be delivered by product developers and service providers. All device types, commands, and functionality defined in current ZigBee PRO-based standards are available to developers in the new standard.

ZigBee 3.0 defines the widest range of device types including home automation, lighting, energy management, smart appliance, security, sensors, and health care monitoring products. It supports both easy-to-use DIY installations as well as professionally installed systems. Based on IEEE 802.15.4, which operates at 2.4 GHz (a frequency available for use around the world), ZigBee 3.0 uses ZigBee PRO networking to enable reliable communication in the smallest, lowest-power devices. Current ZigBee Certified products based on ZigBee Home Automation and ZigBee Light Link are interoperable with ZigBee 3.0. A complete list of standards that have been merged to create ZigBee 3.0 can be seen on the website at www.ZigBee.org.

“The ZigBee Alliance has always believed that true interoperability comes from standardization at all levels of the network, especially the application level which most closely touches the user,” said Tobin J. M. Richardson, President and CEO of the ZigBee Alliance. “Lessons learned by Alliance members when taking products to market around the world have allowed us to unify our application standards into a single standard. ZigBee 3.0 will allow product developers to take advantage of ZigBee’s unique features such as mesh networking and Green Power to deliver highly reliable, secure, low-power, low-cost solutions to any market.”



Finally, we have Bluetooth Smart mesh.

CSRmesh enables Bluetooth® low energy devices not only to receive and act upon messages, but also to repeat those messages to surrounding devices thus extending the range of Bluetooth Smart and turning it into a mesh network for the Internet of Things.



While the CW event was not able to discuss all possible technologies (and believe me there are loads of them), there are other popular contenders. Cellular IoT (CIoT) is one if them. I have blogged about the LTE Cat-0 here and 5G here.

A new IEEE Wi-Fi standard 802.11ah using the 900MHz band has been in works and will solve the need of connectivity for a large number of things over long distances. A typical 802.11ah access point could associate more than 8,000 devices within a range of 1 km, making it ideal for areas with a high concentration of things. The Wi-Fi Alliance is committed to getting this standard ratified soon. With this, Wi-Fi has the potential to become a ubiquitous standard for IoT. See also this article by Frank Rayal on this topic.

Finally, there is SIGFOX. According to their website:

SIGFOX uses a UNB (Ultra Narrow Band) based radio technology to connect devices to its global network. The use of UNB is key to providing a scalable, high-capacity network, with very low energy consumption, while maintaining a simple and easy to rollout star-based cell infrastructure.

The network operates in the globally available ISM bands (license-free frequency bands) and co-exists in these frequencies with other radio technologies, but without any risk of collisions or capacity problems. SIGFOX currently uses the most popular European ISM band on 868MHz (as defined by ETSI and CEPT) as well as the 902MHz in the USA (as defined by the FCC), depending on specific regional regulations.

Communication on SIGFOX is secured in many ways, including anti-replay, message scrambling, sequencing, etc. The most important aspect of transmission security is however that only the device vendors understand the actual data exchanged between the device and the IT systems. SIGFOX only acts as a transport channel, pushing the data towards the customer's IT system.

An important advantage provided by the use of the narrow band technology is the flexibility it offers in terms of antenna design. On the network infrastructure end it allows the use of small and simple antennas, but more importantly, it allows devices to use inexpensive and easily customizable antennas.


Sigfox is also working on project Mustang, a three-year effort to build a hybrid satellite/terrestrial IoT (internet of things) network. According to Rethink Research:

The all-French group also contains aerospace firm Airbus, research institute CEA-Leti and engineering business Sysmeca. The idea is to use Sigfox as the terrestrial data link, with satellite backhaul and connections to planes and boats provided by a low-earth orbit (LEO) satellite constellation.
...
The satellite link could be added to either the end devices or the base station, so that if a device was unable to connect to the terrestrial Sigfox network, it could fall back to the satellite.

While the power requirements for this would be prohibitive for ultra-low power, battery-operated devices, for those with a wired power supply and critical availability requirements (such as smart meters, alarms, oil tankers and rigs) the redundancy would be an asset. These devices may transmit small amounts of data but when they do need to communicate, the signal must be assured.

The Sigfox base station could be fitted with a satellite uplink as a primary uplink as well as a redundancy measure in some scenarios where terrestrial network reach cannot be achieved. With a three-year lifecycle, Mustang’s participants are looking to create a seamless global network, and note that the planned dual-mode terrestrial/satellite terminal will enable switching between the two channels in response to resource availability.

The group says that the development of this terminal modem chipset is a priority, with later optimization of the communication protocols being the next step before an application demonstration using an airplane.

The project adds that the full potential of the IoT can only be achieved by offering affordable mobile communications at a global scale and reach. Key to this is adapting existing networks, according to the group, which explains why Sigfox has been chosen – given that the company stresses the affordability of its system.

Well, there are a lots of options available. We just have to wait and see which ones work in what scenarios.

Report on Spectrum Usage and Demand in the UK


Last week at work, we released a report titled "UK Spectrum Usage & Demand". The only time most people hear about spectrum is when there are some auctions going on. Often a small chunk of spectrum gets sold off for billion(s) of dollars/pounds and these surely make a headline. As I recently found out, 50% of spectrum in UK is shared and 25% is license exempt.

Anyway, this first edition of the report focuses on Public Mobile, Utilities, Business Radio and Space/Satellites. Space is becoming an important area of focus here as it is a significant contributor to the UK economy.

Anyway, the report is embedded below and is available to download from here:

LTE Category-0 low power M2M devices


While we have talked about different LTE categories, especially higher speeds, we have not yet discussed Category-0 or Cat-0 for M2M.

A recent news report stated the following:

CAT-1 and CAT-0 are lower speed and power versions of the LTE standard which dramatically extend the addressable market for carriers and chip makers alike. They introduce new IoT targeted features, extend battery operation and lower the cost of adding LTE connectivity.
“While chipsets supporting these lower categories are essential for numerous applications, including wearable devices, smart home and smart metering, there has been an industry development gap that we had anticipated two years ago,” said Eran Eshed, co-founder and vice president of marketing and business development at Altair. “We’ve worked hard to address this gap by being first to market with true CAT-1 and 0 chipsets featuring a power/size/cost combination that is a massive game-changer.”
Ericsson has an interesting presentation that talks about LTE evolution for cellular IoT. While Rel-12 Cat-0 would use the normal allocated bandwidth (upto 20MHz), Rel-13 plans further enhancements to save even more power by reducing the bandwidth to 1.4Mhz. Another possible saving of power comes from the use of Half Duplex (but its optional). There is a very interesting presentation from Mstar semiconductors on half duplex that I have blogged about here. Anyway, the presentation from Ericsson is here:



When we talk about 50 billion M2M devices, a question that I regularly ask is how many of them will be using cellular and how many will use other technologies. Its good to see that my skepticism is shared by others as well, see the tweet below.

Click on the pic.twitter.com/Z7s6wqxkBM to see the actual media.

Nokia has also got an interesting whitepaper on this topic which talks about optimizing LTE and the architectural evolution that will lead cellular LTE to become a compelling technology so that it can be widely adopted. That paper is embedded as well below.

5G: A 2020 Vision


I had the pleasure of speaking at the CW (Cambridge Wireless) event ‘5G: A Practical Approach’. It was a very interesting event with great speakers. Over the next few weeks, I will hopefully add the presentations from some of the other speakers too.

In fact before the presentation (below), I had a few discussions over the twitter to validate if people agree with my assumptions. For those who use twitter, maybe you may want to have a look at some of these below:







Anyway, here is the presentation.

Different flavours of Bluetooth: 4.0, 4.1, Low Energy, Smart, Smart Ready...

Once upon a time, Nokia proposed a standard called Wibree. That standard was good enough to be merged with Bluetooth SIG and then become part of Bluetooth Low Energy (Bluetooth LE or BLE) standards.


The Bluetooth Low Energy standards comes in two different flavours, 'Smart' and 'Smart Ready'
The Smart and Smart Ready were introduced in 2011 to explain which devices will be compatible to what. Here is a table which explains how interoperability would work.


One of the obvious use of Bluetooth Low Energy is in Beacons. Here is an excellent presentation on Bluetooth 4.0:



Bluetooth 4.1 brings new capabilities in Bluetooth for it to become a challenger for Internet of Things (IoT). Here is an extract from an article in Network Computing:

With 4.1, the Bluetooth SIG is aiming to become a major player in the much-hyped Internet of Things (IOT) market. While 4.0 steps on Wi-Fi’s turf for location-based interaction with client devices, Bluetooth 4.1 looks to leverage Bluetooth's broad name recognition, widespread acceptance, and new low-power capabilities to compete with technologies that also want in on the IOT. These include ZigBee and Near Field Communication, both which are arguably niche technologies that just aren't familiar to many people.

As IoT looms larger for environments of all sizes, Bluetooth 4.1 allows client devices to daisy-chain to each other and multiple devices simultaneously for larger networks that are more Zigbee-like. Perhaps the biggest change for those of us who have to guide our network environments into the future: Bluetooth’s latest version lays the groundwork for dedicated device channels and the use of IPv6 for smart sensors to bridge themselves out of the isolated PAN world and into the IOT. This represents a major and substantial change to the Bluetooth mission, and will absolutely impact the Zigbee market in some substantial way.

Other features with Bluetooth 4.1 make it generally better in its PAN role. Bluetooth has been improved to ensure that nearby LTE radios (frequently under the same device hood) are not interfered with. It has a longer allowable interval between service advertisements, for better battery life and less chatter in the busy 2. GHz band. One of the big gains with 4.1 is the Bulk Transfer feature. For example, the feature would allow my fitness gizmo to auto-transfer all the data it's recorded of my gym activities when I get within range of my cell phone to update the app that tracks my activities.

An FAQ from the Bluetooth SIG on 4.1 is embedded below:

Security and other development on the Embedded SIM


Its no surprise that GSMA has started working on Embedded SIM specifications. With M2M getting more popular every day, it would make sense to have the SIM (or UICC) embedded in them during the manufacturing process. The GSMA website states:

The GSMA’s Embedded SIM delivers a technical specification to enable the remote provisioning and management of Embedded SIMs to allow the “over the air” provisioning of an initial operator subscription and the subsequent change of subscription from one operator to another.
The Embedded SIM is a vital enabler for Machine to Machine (M2M) connections including the simple and seamless mobile connection of all types of connected vehicles. In the M2M market the SIM may not easily be changed via physical access to the device or may be used in an environment that requires a soldered connection, thus there is a need for ‘over the air’ provisioning of the SIM with the same level of security as achieved today with traditional “pluggable” SIM. It is not the intention for the Embedded SIM to replace the removable SIM currently used as the removable SIM still offers many benefits to users and operators in a number of different ways – for example, the familiarity of the form factor, easy of portability, an established ecosystem and proven security model.
















The last time I talked about embedded SIM was couple of years back, after the ETSI security workshop here. Well, there was another of these workshops recently and an update to these information.


The ETSI presentation is not embedded here but is available on Slideshare here. As the slide says:

An embedded UICC is a “UICC which is not easily accessible or replaceable, is not intended to be removed or replaced in the terminal, and enables the secure changing of subscriptions” (ETSI TS 103 383)


Finally, Embedded SIM should not be confused with Soft-SIM. My last post on Soft-SIM, some couple of years back here, has over 15K views which shows how much interest is there in the soft SIM. As the slide says:

Soft or Virtual SIM is a completely different concept that does not use existing SIM hardware form factors and it raises a number of strong security issues:

  • Soft SIM would store the Operator secret credentials in software within the Mobile device operating system - the same system that is often attacked to modify the handset IMEI, perform SIM-Lock hacking and ‘jail-break’ mobile OS’s
  • Operators are very concerned about the reduction in security of their credentials through the use of Soft SIM. Any SIM approach not based on a certified hardware secure element will be subject to continual attack by the hacking community and if compromised result in a serious loss of customer confidence in the security of Operator systems
  • Multiple Soft SIM platforms carrying credentials in differing physical platforms, all requiring security certification and accreditation would become an unmanageable overhead – both in terms of resource, and proving their security in a non-standardised virtual environment

The complete GSMA presentation is as follows:

Rise of the "Thing"

Light Reading carried an interesting cartoon on how M2M works. I wouldnt be surprised if some of the M2M applications at present do work like this. Jokes apart, last week the UK operator EE did a very interesting presentation on Scaling the network for the Rise of the Thing.

A question often asked is "What is the difference between the 'Internet of Things' (IoT) and 'Machine to Machine' (M2M)?". This can generate big discussions and can be a lecture on its own. Quora has a discussion on the same topic here. The picture above from the EE presentation is a good way of showing that M2M is a subset of IoT. 

Its also interesting to note how these 'things' will affect the signalling. I often come across people who tell me that since most M2M devices just use small amounts of data transfer, why is there a need to move from GPRS to LTE. The 2G and 3G networks were designed primarily for Voice with Data secondary function. These networks may work well now but what happens when the predicted 50 Billion connected devices are here by 2020 (or 500 Billion by 2030). The current networks would drown in the control signalling that would often result in congested networks. Congestion control is just one of the things 3GPP is working on for M2M type devices as blogged earlier here. In fact the Qualcomm presentation blogged about before does a decent job of comparing various technologies for IoT, see here.

The EE presentation is embedded as follows:



Another good example website I was recently made aware of is http://postscapes.com/internet-of-things-examples/ - worth checking how IoT would help us in the future.

LTE for Utilities and Smart Grids

This has been an area of interest for the last couple of years. Discussions have been centred around, "Is LTE fit for IoT?", "Which technology for IoT", "Is it economical to use LTE for M2M?", "Would small cells be useful for M2M?", etc.

Ericsson has recently published a whitepaper titled "LTE for utilities - supporting smart grids". One of the table that caught my eye is as follows:


LTE would be ideally suited for some of the "Performance class" requirements where the transfer time requirements is less than 100ms. Again, it can always be debated if in many cases WiFi will meet the requirements so should WiFi be used instead of LTE, etc. I will let you form your own conclusions and if you are very passionate and have an opinion, feel free to leave comment.

The whitepaper is embedded below:

Making LTE fit for the IoT

Another presentation from the #FWIC2013. This presentation by Vodafone covers some of the areas where the LTE standards are being tweaked for making M2M work with them without issues.


Another area is the access barring that I have blogged about before here. This will become important when we have loads of devices trying to access the network at the same time.

From M2M Communications to IoT

M2M was again in the news recently when a new report suggested that it would be $1 Trillion industry. Back in december I posted a detailed presentation on M2M that has now crossed over 6K views. This shows that there is an appetite for this topic. So here is a three part presentation on M2M and IoT. In fact as I pointed out in a post last year, it is very often referred to as IoE (Internet of Everything) rather than IoT (Internet of Things). If this is a topic close to your heart then please do come to the Future of Wireless International Conference (FWIC) organised by Cambridge Wireless on 1st and 2nd July 2013. Details here.

Connected Lighting of the future

This is an advertisement from Philips about their personal wireless lighting system called Hue. This is also the reason why we say that in future everything would be connected and with its own IP address (though this is not the case in Hue).


With Internet of Things (IoT) becoming more mainstream, it would be interesting to see these things becoming more popular and we will hopefully see more interesting apps.

This article makes an interesting reading too.

Evolution of 'Internet of Things' to 'Internet of Everything' #IoE



Will the 'Internet of Humans' and the 'Internet of Things' (IoT) evolve into 'Internet of Everything' (IoE). This is certainly what Dave Evans, the Cisco Futurist thinks. This is from his blog:


From the Internet of Things (IoT), where we are today, we are just beginning to enter a new realm: the Internet of Everything (IoE), where things will gain context awareness, increased processing power, and greater sensing abilities. Add people and information into the mix and you get a network of networks where billions or even trillions of connections create unprecedented opportunities and give things that were silent a voice.

As more things, people, and data become connected, the power of the Internet (essentially a network of networks) grows exponentially. This thinking (“Metcalfe’s law”) comes from Robert Metcalfe, well-known technologist and founder of 3Com, who stated that the value of a network increases proportionately to the square of the number of users. In essence, the power of the network is greater than the sum of its parts, making the Internet of Everything, incredibly powerful.

Imagine the Future - by Cisco

Here is a video from Cisco from the last year, that I think is still relevant to help put in perspective where the future is going:




There is also a slide cast worth watching on the same topic from last month:
