Happy New Year everyone! Just before the stroke of midnight I called my Mum to wish her Happy New Year (the rest of my family were either out or in bed asleep) – and, whilst doing so, I tried to send an SMS/text message to my GESF.
Silly me! I’ve been taught about the mobile phone/cellphone network system and its operation over many years (I think my first lecture about how the UK mobile phone network operates was given to me over 10 years ago) and my knowledge about the PSTN (Public Switched Telephone Network: i.e. the “normal landline” system) should have reminded me of something. From 11.45pm to approximately 1.30am on New Years Eve/Day is one of the busiest times for the networks (“Mothers Day” is one of the other ‘big’ days when telephone network congestion is usually at the highest). If you think that the whole network of transceivers that the mobile phone network uses has been based on the assumption that no more than X number of phones will be using each one at any time – and then you get a whole load of people trying to send messages/make calls at the same time period, then the system begins to fail. If I remember correctly during Christmas/New Year 1998 one British mobile phone network nearly completely failed and engineers had to be called out to a few transmitter points to manually bring them up. 2000 resulted in the networks being practically unusable for around 3 hours.
