4G mobile prototypes presented in Japan
The Japanese telephone company DoCoMo has presented the fourth generation mobiles that they are developing. Although at the moment they are prototypes, a real test was done with them: 32 high-definition videos were seen while traveling in a car at 20 km / h, with more than satisfactory results. And it is that, according to the company, while the vehicle is in motion the download speed is 100 Mbps, while in static, this speed can be increased to Gigabit per second.
Recall that the third generation, technology that is being implemented now in Spain, has an average download speed of 384 kilobits per second, so the difference is abysmal.
And what remains, because the fourth generation will not begin to spread in Japan until 2010. I do not want to think about what it will take here.
