Arthur C. Clarke's thoughts on the future, computers and the internet from 1974. Was he right or what? (GiGadgets) #HistoryOfTechnology
A couple of cellular street-works installations in York. We talk a lot about network densification in #5G however it really started with the need for #2G area capacity uplift in the late 1990s... #historyoftechnology #GSM
You may be able to tell that today's focus has been on removing legacy from the network. Here's a classic from days gone by... A Nokia 1 x TRX GSM1800 PrimeSite, installed as a test BTS in an Orange UK switch site. #2G #GSM #historyoftechnology
Happy 29th anniversary to Orange UK launched on 28th April 1994. From 4th entrant to the UK market, to number 1 network in a very short period of time. Amazing people do amazing things... #2G #GSM #historyoftechnology

Just finished reading this book, highly recommended, whether you work in tech or want a perspective on how the world works... #Semiconductors #HistoryofTechnology
The cheapest piece of test equipment I've ever owned, but wow did this save me a lot of time over the years... Ideal for checking which is the transmit/receive port on a 75 ohm E1 coaxial circuit, as used throughout GSM for transmission connectivity #2G #GSM #historyoftechnology

The inner workings of a Siae B Series point to point digital microwave radio transceiver - used by Orange as "high-order" transmission links, meaning they carried Ater interface traffic, and later Gb was added, from distribted BSCs to MSC sites #2G #GSM #historyoftechnology
The Motorola Razr V3 was a very stylish flip-phone, introduced in 2004. #techhistory #historyoftechnology #vintagephone #mobilephone #cellphone electronics-notes.com/articles/histo…
A focus on 900 MHz GSM on this tower - Vodafone at the top with O2, previously Cellnet, below. Site also supports Airwave TETRA along with other radio services. #2G #GSM #historyoftechnology
When vacuum cleaners were first sold, apparently they were used for some unintended purposes! #historyoftechnology
What a journey GSM has been, the innovation in handset design, prior to the smartphone form factor (which in itself is remarkable and clearly changed the game). #2G #GSM #historyoftechnology @nokia
Dokunmatik ekranlar hayatımıza, işimize yakın geçmişte dahil oldular değil mi? Neredeyse yeni bir teknoloji olduğunu bile söyleyebiliriz. Halbuki prototipleri 1960'lara dayanıyor. Paylaştığım videodaki prototip ise 1980'lere ait. #historyoftechnology #touchscreen
Before silicon, there were gears and slide rules Then came the first machines that could think Part 2A of From Slide Rules to AI explores the dawn of computation, when humans first learned to teach logic to metal #HistoryOfTechnology #AI #Computing #Innovation #CognitiveTools
Crossed wires. Because the first telephone cables were made from steel or iron, unshielded poor connections could be "overheard" or cause crosstalk by electromagnetic induction interference. #HistoryOfTechnology

Have you ever wondered what the inside of a 1920s vintage radio might be like? Take a look inside a 3 valve (tube) radio from about 1927 - fascinating!! Watch now: youtu.be/mFnIuPPd4DI #vintageradio #antiqueradio #historyoftechnology #techhistory
On this day in 1904 Ambrose Fleming was seen "scudding down" Gower Street in London (UK) on his way to file his patent for his "Oscillation Valve." Read more: electronics-notes.com/articles/histo… #OnThisDay #TechHistory #HistoryofTechnology #AmbroseFleming

Nice collection of #2G #GSM devices on display at the excellent NorthWest Computer Museum @joekay66 @SpinnersMill - This museum is excellent, well worth a visit, loads of retro computing, many working, including some classic arcade games 💻🖥️⌨️🖱️🎮🕹️👍 #historyoftechnology

The Bird Thru-Line Watt Meter was an essential piece of test equipment during the early days of GSM. Seen here measuring transmit power from an Ericsson RBS205. Reversing the central 'slug' resulted in a VSWR measurement. A very useful tool... #2G #GSM #historyoftechnology
It was common for early GSM900 transmission lines to be connected to existing 900 MHz antennas. In this case the GSM BTS continued to use the old 'corner reflector' antennas, as they were known at the time, for quite a while after analogue switch off #2G #GSM #historyoftechnology
In 2001 JVL launched the world's first integrated servo motor. Many of the first motors are still running on production machines today. If you are also looking to ditch the control cabinet, reach out to us. #historyoftechnology #JVL #Automateshow
