Since the first mobile phones were introduced in 1981, mobile networks have evolved to the point that we can now be connected anywhere and get to see, experience, explore and express ourselves with just a click from the palm of our hand. From 2G, 3G, 4G and Long Term Evolution (LTE) 4G, the maximum capacity that must be supported by each mobile cell has progressively increased in response to an exponential rise in data consumption.
‘Data, data and more data’ has been the demand of mobile-phone users for many years, whether they articulated it or not. This, along with a demand for high quality of service, has prompted considerable innovation in radio technology – GPRS, EDGE, UMTS, WiMAX and many more – with much of the latest effort going into deployment of LTE (long term evolution) systems.
As data demand ramps ever higher, researchers are looking to innovative amplifier designs to help transport a broader light spectrum through optical fibres, finds Andy Extance
Duncan Ellis shares his views about the increased focus on automation from network operators, and how the physical layer has so far stubbornly resisted the move
Switching off copper networks where fibre has been deployed is the end game, so why are so few operators doing it, wonders Pauline Rigby
With demand for fibre to the premises increasing, Keely Portway looks at the role training plays in ensuring installation skills remain available to meet this growing demand
