TechKnowledge Technology Stories (Series 1)

TechKnowledge is a series of Technology Stories looking at how technology has evolved over the years and how it will continue to evolve in the future. The series is targeted at youth looking to understand how technology has been evolving and how it will evolve further. It is our intention to make a ten part series but as of yet only four parts are complete. 

Part 1: 'Smaller, Faster, Cheaper and More…' looks at how technology has evolved by things getting smaller, faster, cheaper and much more. It investigates Moore’s law and how it has helped create a future technology roadmap.

Part 2: 'Connecting Everything Everywhere…' discusses different connectivity options available to connect various devices, gadgets and appliances to the internet. It highlights the fact that this is just the beginning, and everything that can be connected will eventually get connected.

Part 3: 'Satellites - Our Friends In The Sky…' discusses the fact that they are our friends and helpers in the sky. In discusses how satellites are useful as a connectivity option, how it helps us map and navigate, how we can use location based services, how we can watch broadcast video or listen to broadcast radio, and last but not least, how satellites are helping us observe and monitor the earth. 

Part 4: 'Devices and Gadgets - Our Companions and Life Savers…' looks at the fact that we use a variety of electronic devices/gadgets in our everyday lives to make it more convenient, efficient, and even keep us connected. From smartphones and laptops to smart home appliances and wearable tech, these devices simplify tasks, enhance productivity, and provide instant access to information and communication. They help us manage work, stay in touch with loved ones, and access entertainment on the go. Gadgets like fitness trackers promote healthier lifestyles, while others automate household chores, saving time and energy. Overall, the connected devices & gadgets have become essential tools in modern life, blending seamlessly into our routines and transforming how we live and interact.

The History of Camera Phones

Last year, Professor Nigel Linge Director of the Computer Science, Networking and Mathematics Directorate and Professor of Telecommunications at the University of Salford, Manchester presented a talk at IET, titled "Nobody saw it coming - the rise and rise of the camera-phone ". 

The following is the summary of the talk from the flyer (can't find link):

When you buy a new smartphone, what features do you look for? It is probably a safe bet that its ability to make and receive phone calls is well down the list, if on it at all! Yet the quality of the camera is probably near the top. How ironic that a technology that began life as a mobile telephone is now marketed and sold based on everything else it can do. This webinar will examine the extraordinary rise and rise of the camera-phone, from the Sharp J-SHO4 in 2000, to pushing the megapixel count up from one in 2004 to five in 2006, and then eight in 2008 to today's one-hundred plus megapixel, 4K HD video recording, multi-camera, offerings. From the first selfies, to transforming social media and turning everyone into an on-the-spot news reporter, the camera-phone has had a phenomenal impact on society in its first twenty years.

I definitely recommend watching the video, it's available on the IET page here.

A Primer on Pagers

After Avengers clip about Nick Fury paging Captain Marvel, I was asked by a few people about what, why and how of Pagers. Similar questions were asked when Tron: Legacy was released. It took me a while but finally managed to make a non-technical introduction on Pagers for people with very basic understanding of technology.

If you used pagers in past, tell me about the good, the bad and the ugly of pagers.

#CWHeritage Talk: The History of Synchronization in Digital Cellular Networks

CW (a.k.a. Cambridge Wireless) held a very interesting event titled 'Time for Telecoms' at the Science Museum in London. I managed to record this one talk by Prof. Andy Sutton, who has also kindly shared slides and some other papers that he mentions in his presentation. You can also see the tweets from the event on Twitter.

The video playlist and the presentation is embedded below.

Nokia Bell Labs - Future Impossible Series Videos

Picture Source: Cnet

Bell Labs, which has played a significant role in telecoms history and has a very glorious list of achievements created a collection of short films highlighting the brilliant minds who created the invisible nervous system of our society. Some of you may be aware that Bell Labs is now a part of Nokia but was previously part of Alcatel-Lucent, Lucent and AT&T before that.

The playlist with 5 videos is embedded below and short details of the videos follows that.


Video 1: Introduction

Introducing 'Future Impossible', a collection of short films highlighting the brilliant minds who created the invisible nervous system of our society, a fantastic intelligent network of wires and cables undergirding and infiltrating every aspect of modern life.


Video 2: The Shannon Limit

In 1948, father of communications theory Claude Shannon developed the law that dictated just how much information could ever be communicated down any path, anywhere, using any technology. The maximum rate of this transmission would come to be known as the Shannon Limit.  Researchers have spent the following decades trying to achieve this limit and to try to go beyond it.


Video 3: The Many Lives of Copper

In the rush to find the next generation of optical communications, much of our attention has moved away from that old standby, copper cabling. But we already have miles and miles of the stuff under our feet and over our heads. What if instead of laying down new optical fiber cable everywhere, we could figure out a way to breathe new life into copper and drive the digital future that way?


Video 4: The Network of You

In the future, every human will be connected to every other human on the planet by a wireless network. But that’s just the beginning. 

Soon the stuff of modern life will all be part of the network, and it will unlock infinite opportunities for new ways of talking, making and being. The network will be our sixth sense, connecting us to our digital lives. In this film, we ponder that existence and how it is enabled by inventions and technologies developed over the past 30 years, and the innovations that still lie ahead of us.


Video 5: Story of Light

When Alexander Graham Bell discovered that sound could be carried by light, he never could have imagined the millions of written text and audio and video communications that would one day be transmitted around the world every second on a single strand of fiber with the dimensions of a human hair.

Follow the journey of a single text message zipping around the globe at the speed of light, then meet the researchers that have taken up Bell’s charge.


For anyone interested, Wikipedia has a good detailed info on Bell Labs history here.

The Iconic British Red Phone Boxes

Source: BBC

Brits love their red phone boxes. Even with mobiles prevalent today, we don't want to get rid of the phone boxes. The BBC estimates that there are 46,000 phones boxes in use today, including 8,000 red ones.

Some of these phone boxes are being put to other interesting uses too. One of them has become 'world's smallest museum', another has been converted into a coffee shop, yet another one is a salad bar and another one in Cumbria is hosting life saving medical equipment. This is all thanks to BT that has encouraged adoption of some of these much loved icons for as little as £1.

Two British Phonebox enthusiasts, Prof. Nigel Linge and Prof. Andy Sutton have written a very well researched and comprehensive book on this topic looking at the history and evolution of the humble phone boxes through all of its major models, including those that were introduced by organisations such as the emergency services. The British Phonebox is available to purchase from Amazon and other popular bookshops.

In addition to the book, they have also written an article in 'The Journal' that gives a taster of whats in the book. Its available to download here.

5 interesting facts from the little reading that I did on this topic:

• The model K1 (K stand for Kiosk) was very unpopular and hence a competition was held to find the best possible design. The winning design by Sir Giles Gilbert Scott became K2 that was rolled out in 1926
• Sir Giles had suggested silver colour with blue and green interior. This was changed to red for making it easy to spot
• The latest model is called KX100+
• The most popular and loved model is the K6 that was designed to celebrate King George V’s Silver Jubilee, though he died before any of them were actually installed.
• Before Queen Elizabeth came along, a vague representation of the Tudor crown was used on the telephone boxes. Wanting to put her stamp on things after she ascended to the throne in 1952, QEII had all of the crowns changed to St. Edward's Crown, the crown actually used in coronations. Scotland opted to keep the Crown of Scotland on theirs, and so all K6 boxes manufactured after 1955 had to be made with a slot in the top to insert the plate with the correct crown depending on the location of the booth.

History: 30 years of the mobile phone in the UK

In January 1985 the UK launched its first mobile networks. Now, thirty years on, many people and companies in the UK have been celebrating this enormous achievements and advances that have been made since then and which have seen the mobile evolve from a humble telephone into the multimedia pocket computer which has become such an essential part of modern life. It was simply not possible in 1985 to envisage a country that would be able to boast more active mobile phones than people or to have along the way clocked up several world firsts, and be now leading on the deployment of 4G and shaping the future 5G technologies.

100 years of Wireless History

Recently attended the Cambridge Wireless Inaugural Wireless Heritage SIG event, “100 years of radio”. Some very interesting presentations and discussions on the wireless history. 

Each of the presenters touched on a double-decade period and focussed on the lessons that can be learnt from that time and their relevance today. Focusing on 20 year timeframes, the event walked us through the exciting rise and evolution of wireless technology from 1914 to present day, while showcasing live demos from each age.

Presentations were heard from:

• Colin Smithers, Chairman, Plextek "1914-1934: The wireless wave" - The Wireless Telegraphy Handbook of 1913 speculated on the future use of Continuous Waves and sets a benchmark against which fundamental trends in the industry can be measured and predicted including data costs and technology and transmission standard life spans. (PDF)
• Geoff Varrall, Director, RTT Online "1934 - 1945: The wireless war" - In his controversial book The Origins of the Second World War the revisionist historian AJP Taylor argues that the Second World War was not caused by Hitler but was the result of a combination of factors including the rapid growth of broadcasting technology. So was this the wireless war? (PDF)
• Steve Haseldine, CEO, Deaf Alerter, "1945 to 1974: The cold war - radio goes underground" - The National Communication Radio System, spy and clandestine radio, preparing for the Third World War (PDF)
• Nigel Linge, Professor of Telecommunications,  School of Computing, Science and Engineering, University of Salford "1974 to 1994" - The transistor comes of age, the role of radio in consumer electronics and cellular radio (PDF)
