small cell architecture incorporates advances such as switched Ethernet fronthaul that allow systems to be designed, installed and tested in a fraction of the time that legacy solutions typically require.
As an LTE system that already incorporates many 5G architectural elements, such as C-RAN
over Ethernet front-haul and cell virtualization, OneCell is designed to streamline operators LTE-to-5G network evolution path, including the coexistence of the two technologies for many years to come.
By combining and extending the objectives of the C-RAN
Alliance and the xRAN Forum, the key principles of the ORAN Alliance include:
In addition to boosting throughput, C-RAN
requires multiple other innovations.
Now, in the proposed C-RAN
system, multiple cells' information is converging in BBU pool, by which the system can get a whole interference picture without UEs' measurements17, 18].
architectures, the Smart CPRI Transport solution provides CPRI fronthaul transport between remote radio heads (RRHs) on cellular towers and centralized baseband units (BBUs).
Radisys and ASOCS virtual base station solution delivers a C-RAN
ready platform that can accelerate mobile operators' cloud deployments and fully realize the benefits of virtualized network functions.
Additionally, China Mobile and Wind River have developed a C-RAN
solution for NFV deployment.
Parallel Wireless is reimagining the cellular RAN as the only provider of wide-area distributed C-RAN
using 100% interoperable 3GPP interfaces and traditional backhaul technologies.
Altiostar's Network Functions Virtualization (NFV) C-RAN
solution includes macro and micro cellular eNodeBs.
ZTE has launched today at Mobile World Congress 2011 a next generation C-RAN
(Cloud of Radio Access Network) wireless networking solution, which is future-proof for the next 10 years.
I explained that C-RAN
technology will dramatically reduce both capital and operational expenses for wireless service providers while providing superior levels of wireless services to users with fewer dropped connections during periods of peak demand.
