Walking through the outskirts of Reading this evening and spotted a bit of #2G history and now #industrialarchaeology in the form of a redundant Orange #GSM lamp-post micro-cell site. These sites were typically deployed to add capacity density to an area. #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

When vacuum cleaners were first sold, apparently they were used for some unintended purposes! #historyoftechnology

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

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

Early One2One dual polarised DCS1800 / GSM1800 antennas with low noise receiver pre-amps (mast head amplifiers / low noise amplifiers) and microwave radio backhaul #2G #GSM #historyoftechnology

Orange transmission cab from 2012, during the early days of Ethernet radio backhaul testing. Unit at top is power distribution for Forem mast head amplifiers. Below this are NEC microwave radios, the bottom unit, below DDF & ADF, is the radio on test #2G #GSM #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

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
