Mobile Backhaul

FEATURE

Backhauling with fibre

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.

Hauling back the years

‘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.

Technological advances to aid the increasing demand for bandwidth, on the path towards the terabit network, should lead to optical signals that are flexible and adaptive, like water, argues Dr Maxim Kuschnerov and Dr Yin Wang
