4. Download data from two base stations
Together with Qualcomm, Nokia Siemens Networks has developed Multiflow. The technology will allow mobile devices located close to the edge of a base station's coverage area to connect with a second base station serving a neighboring area, as well, and download data from two base stations at the same time.
By deploying the technology in its network, operators can double the throughput for users at the cell edge, according to Nokia Siemens.
5. Better Wi-Fi integration
Operators are getting increasingly interested in using Wi-Fi to offload their networks, and in the process offer better overall network performance. The thinking is that users should automatically be connected to the network that offers the best experience.
Earlier this week, Wi-Fi Alliance started certifying products as part of the organization's Passpoint program, which is based on technology defined in its Hotspot 2.0 specification.
Users will be able to authenticate themselves with a SIM card, just as they do on mobile networks. Therefore, certified mobile devices can automatically discover and connect to Wi-Fi networks powered by access points that have also been approved.
6. Use a mixture of small and large cells
The development of so-called het nets, heterogeneous networks, which use a mixture of traditional large base stations and smaller cells, placed in areas where there are a lot of users, will also be an central part of next-generation mobile networks.
At first, the small cells and the large ones will use the same frequency band, according to Färjh. But the industry has also started discussing the ability to use different bands for the small cells, including Time-Division Duplex (TDD) transmission 3.5GHz, he said.
TDD networks send download and upload traffic over one channel, and are, for example, a good fit for video streaming -- since operators can choose to dedicate more spectrum to downlink traffic. In the small cell scenario, operators could create download zones with especially high speeds.
