Nokia，旗下的Bell Labs，其5G報告.....
On April 15, 2015, Nokia agreed to acquire Alcatel-Lucent, the Bell Labs' parent company, in a share exchange worth $16.6 billion.[20][21]Their first day of combined operations was January 14, 2016.[22]

In all the excitement about 5G, it is easy to forget that the most intensive innovations of 2016-2020 will go on in "4.5G" – in Release 13 and 14, of course, but more importantly in the way the carriers and their vendors reinvent their cellular networks with new approaches like virtualization and HetNet, in the desperate bid to keep up with capacity, coverage and efficiency demands.
Nokia’s Bell Labs’ R&D unit published a report this week warning that the capacity of mobile and Wi-Fi networks is not growing nearly quickly enough to satisfy the rise in that demand, especially when it comes to content and video. Of course, such a conclusion, coming from an equipment vendor, is predictable and self-serving, but nonetheless, Bell Labs’ figures are compelling.

5G is looming, but network innovations are needed far more urgently

5G (5th generation mobile networks or 5th generation wireless systems) denotes the next major phase of mobile telecommunications standards beyond the current 4G/IMT-Advanced standards. 5G has speeds beyond what the current 4G can offer.
The Next Generation Mobile Networks Alliance defines the following requirements for 5G networks:
- Data rates of tens of megabits per second should be supported for tens of thousands of users
- 1 gigabit per second to be offered simultaneously to many workers on the same office floor
- Several hundreds of thousands of simultaneous connections to be supported for massive sensor deployments
- Spectral efficiency should be significantly enhanced compared to 4G
- Coverage should be improved
- Signalling efficiency should be enhanced
- Latency should be reduced significantly compared to LTE.[1]
The Next Generation Mobile Networks Alliance feels that 5G should be rolled out by 2020 to meet business and consumer demands.[2] In addition to providing simply faster speeds, they predict that 5G networks also will need to meet new use cases, such as the Internet of Things (network equipment in buildings or vehicles for web access) as well as broadcast-like services and lifeline communication in times of natural disaster.
Although updated standards that define capabilities beyond those defined in the current 4G standards are under consideration, those new capabilities have been grouped under the current ITU-T 4G standards.
