Barcelona MWC2015, 5 g mobile communication has become the hottest topic. Everyone is talking about 5 g, imagining the future.

South Korea telecom CEO Chang - sanda-gyu Hwang said Three years later, the south Korean games will see 5 g. He says, more than 5 g era of innovation and new business will lead to the change of the quality of life beyond imagination, such as the popularity of self-driving cars, such as real time automatic translation, such as the realization of the holographic calls. European commissioner Gunther Oettinger said, 5 g to the telecommunications industry to define business opportunities, energy, transportation, health will become the new business direction. For this reason, an open Internet and more spectrum resources is must be guaranteed. France telecom Orange CEO said Stephane Richard, 5 g will bring the Internet whenever and wherever, telecom and IT will be ten years. Qualcomm CEO Steve Mollenkopf argues that several evolution of LTE, such as LTE MTC, LTE Broadcast, LTE Direct Promimity and LTE Direct communication and LTE - U have hope to be in the future 5 g technology foundation. 5 g compared the difference between 4 g should be better security, more reliable business, user connection, in the center of the cross spectrum of unified platform, and so on. Nokia CEO Rajeev said thought 5 g means the ubiquitous connection, 5 g will be programmable, 5 g do not look down upon to the change of human life. Huawei's CEO Ken hu said 5 g the greatest significance to the whole society is to bring in the true sense of the Internet of things, and huawei hopes to become a leader of 5 g era. Huawei plans from 2013 to 2018 $600 million investment in research and development of 5 g patent technology. Alcatel-lucent bell LABS wireless research vice President Theodore Sizer said that since the bell LABS to research 5 g technology five years ago, they have been the research direction is clear 5 g what issues need to be solved, at this stage is over, now they are shifting to how to solve the problem above. In 2015, the center of gravity of the standardization work is 5 g.

5 g standard has not been issued, this year's MWC, many companies are on display is 5 g technology. We are not the research of mobile communication, we are more interested in 5 g what can bring to optical communications. 3 g era appeared a backhaul, 4 g era have fronthaul again, both optical communication industry to bring huge business opportunities. So 5 g? Edit remember 5 g mobile in the concept of parallel light module and a large number of adoption of parallel optical connector.

There are articles, said the next 5 g communication will use to millimeter wave spectrum. Regardless of millimeter wave frequency band is very close to the light, millimeter wave communication characteristics of many similar to light waves, too. If 5 g is based on millimeter wave, the base station will be smaller, behind the demand for optical fiber transmission will be higher.

5 g into the millimeter wave, 6 g was the waves of light. Optical communication people often complain about optical communication technology updated quickly, but now the upgrading of mobile communication technology is a bit too fast. Editors are likely to be at least 3 g mobile phone can also be used when can see the 5 g.
