In addition, a range of practical issues is identified and addressed in the deployment of CoMP in Heterogeneous Network (HetNet) and Multiple Input Multiple Output (MIMO) system, such as backhaul traffic, synchronization, and feedback design.
Upgrading a network, by contrast, is a hugely expensive process that takes years and costs billions of dollars, as new sites are acquired, base-stations and antennas are erected and backhaul connections are installed to connect them to the network.
One of the main benefits used along with these features is core/backhaul network virtualization which ensures sharing of mobile core and backhaul networks among Mobile Operators (MOs).
Deployment topology: Configuration between LPNs and backhaul hub point.
Under this framework, FHs provide femtocell and backhaul connections.
Digital Inphase / Quadraphase (I/Q) samples are transmitted in C-RAN create latency, jitter and backhaul bandwidth problems.
Last month, Fujitsu announced a whole new line of WiMax products covering every major component in the WiMAX network, including silicon solutions, electronic devices, radio access network solutions, professional services and backhaul infrastructure solutions.
To this end, intensive research is conducted to support MN and UDN, e.g., solutions for in-band backhaul, where the access and backhaul share the same spectrum, specific distributed RRM schemes, or dynamic nomadic node selection for backhaul optimization.
Picocells share a backhaul connection with macrocells and can thus communicate with each other and allow for synchronization and coordination.
Timing synchronization: Coarse time synchronization (Frame synchronization), and fine timing synchronization.
