Europe's first glimpse of a live US baseball game
It is rare to visit a museum dedicated to telecoms, never mind one set in beautiful grounds. Nor does it often happen that the visit coincides with an important anniversary for the site.
La Cité des Télécoms, a museum set in 11 hectares of land in Pleumeur-Bodou, Brittany, France, is where the first TV live feed was sent by satellite from the US to Europe.
The Telstar 1 communications satellite was launched 60 years ago, on July 10, 1962. The first transmission that included part of a live Chicago baseball game almost immediately followed.
By then, a vast horn radio antenna had been constructed and was awaiting the satellite’s first signals. The Radôme houses the antenna, an inflated dome-shaped skin to protect it from the weather. The antenna is built using 276 tonnes of steel and sits on 4,000 m3 of concrete. Just the bolts holding together the structure weigh 10 tonnes. It is also the largest inflated unsupported dome in the world.
The antenna continued to receive satellite transmissions till 1985. The location was then classed as a site of national historical importance. The huge horn antenna is unique since the twin antenna in the US has been dismantled.
The Cité des Télécoms museum was opened in 1991 and the site is a corporate foundation supported by Orange.
History of telecoms
A visitor to the museum is guided through a history of telecoms.
The tour begins with key figures of telecom such as Samuel Morse, Guglielmo Marconi, Lee de Forest and Thomas Edison. Lesser known inventors are also included, like Claude Chappe, who developed a semaphore system that eventually covered all of France.
The tour moves on to the advent of long-distance transmission of messages using telegraphy. Here, a variety of exquisitely polished wooden telegraphy systems are exhibited. Also included are rooms that explain the development of undersea cables and the advent of optical fibre.
In the optical section, an exhibit allows a user to point a laser at different angles to show how internal reflection of an optical fibre always guides the incident light to the receiver.
Four video displays expertly explain to the general public what is single-mode fibre, optical amplification, wavelength-division multiplexing, forward error correction, and digital signal processing.
The digital age
Radio waves and mobile communications follow before the digital world is introduced, starting with George Boole and an interactive display covering Boolean algebra. Other luminaries introduced include Norbert Wiener and Claude Shannon.
There are also an impressive collection of iconic computing and communications devices, including an IBM PC, the Apple II, an early MacBook, generations of mobile phones, and the French’s effort to computerise the country, the Minitel system, which was launced in 1982 and was only closed down in 2012.
The tour ends with interactive exhibits and displays covering the Web, Bitcoin and 5G.
The Radôme
The visit’s highlight is the Radôme.
On entering, you arrive in a recreated office containing 1960s engineering paraphernalia – a technical drawing board, slide rules, fountain pens, and handwritten documents. A guy (in a video) looks up and explains what is happening in the lead-up to the first transmission.
You then enter the antenna control centre and feel the tension and uncertainty as to whether the antenna will successfully receive the Telstra transmission. From there, you enter the vast dome housing the antenna.
TV displays take you through the countdown to the first successful transmission. Then a video display projected onto the vast ceiling gives a whistle-stop tour of the progress made since 1962: images sent from the moon landing in 1969, live World Cup football matches in 1970 through to telecom developments of the 1980s, 1990s, and 2000s.
The video ends with a glimpse of how telecoms may look in future.
Future of telecoms
The Radôme video is the closest the Cité des Télécoms museum comes to predicting the future and more would have been welcome.
But perhaps this is wise since, when you exit the Radome, a display bordering a circular lawn shows each key year’s telecom highlight from 1987 to 2012.
In 1987, the first optical cable linked Corsica to mainland Europe. The following year the first transatlantic optical cable (TAT-8) was deployed, while Bell Labs demonstrated ADSL in 1989.
The circular lawn display continues. In 1992, SMS was first sent, followed by the GSM standard in 1993. France Telecom’s national network became digital in 1995. And so it goes, from the iPhone in 2007 to the launch of 4G in Marseille in 2012.
There the display stops. There is no mention of Google, data centres, AI and machine learning, network functions virtualization, open RAN or 6G.
A day out in Brittany
The Radôme and the colossal antenna are a must-see, while the museum does an excellent job of demystifying telecoms. The museum is located in the Pink Granite Coast, a prime tourist attraction in Brittany.
Perhaps the museum’s key takeaway is how quickly digitisation and the technologies it has spawned have changed our world.
What lies ahead is anyone’s guess.
Books in 2013 - Part 1
Gazettabyte is asking various industry figures to highlight books they have read this year and recommend, both work-related and more general titles.
Part 1:
Tiejun J. Xia (TJ), Distinguished Member of Technical Staff, Verizon
The work-related title is Optical Fiber Telecommunications, Sixth Edition, by Ivan Kaminow, Tingye Li and Alan E. Willner. This edition, published in 2013, includes almost all the latest development results of optical fibre communications.
My non-work-related book is Fortune: Secrets of Greatness by the editors of Fortune Magazine. While published in 2006, the book still sheds light on the 'secrets' of people with significant accomplishments.
Christopher N. (Nick) Del Regno, Fellow Verizon
OpenStack Cloud Computing Cookbook, by Kevin Jackson is my work-related title. While we were in the throes of interviewing candidates for our open Cloud product development positions, I figured I had better bone up on some of the technologies.
One of those was OpenStack’s Cloud Computing software. I had seen recommendations for this book and after reading it and using it, I agree. It is a good 'OpenStack for Dummies' book which walks one through quickly setting up an OpenStack-based cloud computing environment. Further, since this is more of a tutorial book, it rightly assumes that the reader would be using some lower-level virtualisation environment (e.g., VirtualBox, etc) in which to run the OpenStack Hypervisor and virtual machines, which makes single-system simulation of a data centre environment even easier.
Lastly, the fact that it is available as a Kindle edition means it can be referenced in a variety of ways in various physical locales. While this book would work for those interested in learning more about OpenStack and virtualisation, it is better suited to those of us who like to get our hands dirty.
My somewhat work-related suggestions include Brilliant Blunders: From Darwin to Einstein – Colossal Mistakes by Great Scientists That Changed Our Understanding of Life and the Universe, by Mario Livio.
I discovered this book while watching Livio’s interview on The Daily Show. I was intrigued by the subject matter, since many of the major discoveries over the past few centuries were accidental (e.g. penicillin, radioactivity, semiconductors, etc). However, this book's focus is on the major mistakes made by some of the greatest minds in history: Darwin, Lord Kelvin, Pauling, Hoyle and Einstein.
It is interesting to consider how often pride unnecessarily blinded some of these scientists to contradictions to their own work. Further, this book reinforces my belief of the importance of collaboration and friendly competition. So many key discoveries have been made throughout history when two seemingly unrelated disciplines compare notes.
Another is Beyond the Black Box: The Forensics of Airplane Crashes, by George Bibel. As a frequent flyer and an aviation buff since childhood, I have always been intrigued by the process of accident investigation. This book offers a good exploration of the crash investigation process, with many case studies of various causes. The book explores the science of the causes and the improvements resulting from various accidents and related investigations. From the use of rounded openings in the skin (as opposed to square windows) to high-temperature alloys in the engines to ways to mitigate the impact of crash forces on the human body, the book is a fascinating journey through the lessons learned and the steps to avoid future lessons.
While enumerating the ways a plane could fail might dissuade some from flying, I found the book reassuring. The application of the scientific method to identifying the cause of, and solution to, airplane crashes has made air travel incredibly safe. In exploring the advances, I’m amazed at the bravery and temerity of early air travelers.
Outside work, my reading includes Doctor Sleep, by Stephen King. The sequel to “The Shining” following the little boy (Dan Torrence) as an adult and Dan’s role-reversal now as the protective mentor of a young child with powerful shining.
I also recommend Joyland (Hard Case Crime), by Stephen King. King tries his hand at writing a hard-case crime novel with great results. Not your typical King…think Stand by Me, Hearts in Atlantis, Shawshank Redemption.
Andrew Schmitt, Principal Analyst, Optical at Infonetics Research
My work-related reading is Research at Google.
Very little signal comes out of Google on what they are doing and what they are buying. But this web page summarises public technical disclosures and has good detail on what they have done.
There are a lot of pretenders in the analyst community who think they know the size and scale of Google's data center business but the reality is this company is sealed up tight in terms of disclosure. I put something together back in 2007 that tried to size 10GbE consumption (5,000 10GbE ports a month ) but am the first to admit that getting a handle on the magnitude of their optical networking and enterprise networking business today is a challenge.
Another offending area is software-defined networking (SDN). Pundits like to talk about SDN and how Google implemented the technology in their wide area network but I would wager few have read the documents detailing how it was done. As a result, many people mistakenly assume that because Google did it in their network, other carriers can do the same thing - which is totally false. The paper on their B4 network shows the degree of control and customisation (that few others have) required for its implementation.
I also have to plug a Transmode book on packet-optical networks. It does a really good job of defining what is a widely abused marketing term, but I’m a little biased as I wrote the forward. It should be released soon.
The non-work-related reading include Nate Silver’s book: The Signal and the Noise: Why So Many Predictions Fail — but Some Don't . I am enjoying it. I think he approaches the work of analysis the right way. I’m only halfway through but it is a good read so far. The description on Amazon summarises it well.
But some very important books that shaped my thinking are from Nassim Taleb . Fooled by Randomness is by far the best read and most approachable. If you like that then go for The Black Swan. Both are excellent and do a fantastic job of outlining the cognitive biases that can result in poor outcomes. It is philosophy for engineers and you should stop taking market advice from anyone who hasn’t read at least one.
The Steve Jobs biography by Walter Isaacson was widely popular and rightfully so.
A Thread Across the Ocean is a great book about the first trans-Atlantic cable, but that is a great book only for inside folks – don’t talk about it with people outside the industry or you’ll be marked as a nerd.
If you are into crazy infrastructure projects try Colossus about the Hoover Dam and The Path Between the Seas about the Panama Canal. The latter discloses interesting facts like how an entire graduating class of French engineers died trying to build it – no joke.
Lastly, I have to disclose an affinity for some favourite fiction: Brave New World, by Aldous Huxley and The Fountainhead by Ayn Rand.
I could go on.
If anyone reading this likes these books and has more ideas please let me know!
