One of the transmission methods that has become popular over the last few years is the mobile phone network. Traditional means of wireless communications had become expensive and companies began to realise that the cellular network could be used as an alternative. Hardware costs have become to fall in particular the cost of GSM modems and this has led to more manufacturers entering the market. Data rates are small and can be easily accommodated by a cellular network and the predicted growth to M2M Communications and the Internet of things (IoT) has seen the big mobile phone operators now offer the technology as a core service. The evolution to 4G and LTE advanced means data will be sent over a packet based network with web enabled ip connectivity. ubiquitous. Improved latency levels in LTE advanced networks will ensure that mission critical applications can be accommodated by the networks.
