Today I read an article about how for many years many countries have had plans to replace FM radio with a digital replacement such as DAB. There has been some success in some countries such as the UK, but by and large everyone admits that FM is here to stay for another decade at least. It's not that the digital systems aren't better or deliver advanced audio quality but it's difficult to beat that FM radio that only costs a couple of cents and is built into everything from cars to mobile phones with technology that still costs an order of a magnitude more. This left me wondering if things will be similar with GSM!? We are soon going to celebrate it's 20th anniversary in the wild and still, this technology shows no signs of being replaced and being made redundant anytime soon. My predictions for GSM I made back in 2007 still hold.
