Menu Button OUTDOOR OPENRAN MORE The need to provide both coverage and capacity while supporting growing data consumption, all with declining ARPUs, have placed tremendous pressure on MNOs to find the most efficient use of their allocated radio spectrum. Our outdoor OpenRAN solution helps with spectrum optimization to make mobile operators profitable. The architecture consists of an OpenRAN Controller orchestrating: Virtualized Baseband Unit (vBBU): Based on Intel-based COTS (x86) hardware, this component provides CU and DU functionality. It communicates to a cluster of RRHs (which contain RF and lower PHY) and supports multiple carriers based on the RRH cluster’s load. The interface between vBBU and RRH is based on Ethernet-based eCPRI. This architecture supports 4G today and is software-upgradable to 5G. Remote radio heads (RRH): The Parallel Wireless solution incorporates standard, off-the-shelf RRHs and small cells from different OEMs. These OpenRAN RRHs and small cells can be integrated into our solution with minimum integration effort, reducing the overall cost of ownership for mobile operators. Parallel Wireless has developed extensive OpenRAN partnerships for macros, small cells and Massive MIMOs to support all use cases for coverage and capacity. Macros and Massive MIMO When operators build a network, they typically start by building a macro layer, mainly consisting of rooftop sites and towers to quickly deliver the largest possible coverage area. Parallel Wireless has an ecosystem of OpenRAN hardware to deliver the most efficient and powerful solutions to deliver coverage and capacity from 2×2 to 4×4 in different frequency bands – all software-defined and easily upgradable to 5G. Moving from MIMO to massive MIMO, according to IEEE, involves making “a clean break with current practice,” as it requires a large number of service antennas over active terminals, as well as time-division duplex operation. “…By focusing energy into ever smaller regions of space, [Massive MIMO brings] huge improvements in throughput and radiated energy efficiency.” The group calls out other benefits including cheaper parts, lower latency, simplification of the MAC layer, and robustness against intentional jamming. However, M-MIMO presents deployment challenges as well: Heavier antennas, meaning that existing poles may not be able to bear the load, and any upgrades required will necessitate additional deployment costs Power upgrades, as new active antennas will consume more power, which will be an additional operational cost as well as capital cost Backhaul upgrades, as existing backhaul may not be able to cope with the projected massive increase in data traffic With Parallel Wireless and its massive MIMO ecosystem partners, MNOs can select hardware based on their 5G deployment cases, budget and subscriber needs. Our OpenRAN Massive MIMO delivers: A compact solution with perfect component synchronization that is easy to deploy Support for any deployment scenario Internal power consumption reduction to achieve total energy efficiency reductions. LEARN MORE SMALL CELLS for DENSIFICATION 5G networks will push the limits for small cell deployments. The Parallel Wireless OpenRAN approach solves the triple challenge of interference, mobility and deployment: A combination of intra- and inter-frequency underlay and overlay cells will be a common practice in 5G networks. In a spatial densification deployment, the OpenRAN Controller manages intra-cell interferences, and for a vertical densification deployment it will coordinate all load-related handoffs and other functionalities to utilize different layers accordingly, thus improving overall system performance and frequency utilization. The split concept (DU and CU) for 5G facilitates a simpler approach toward frequency coordination among different cells in a geographical area. This approach to small cell deployments enables different DUs with the same or different operating frequencies to be connected and coordinated through a single CU (Parallel Wireless vCU as a VNF in OpenRAN software suite). All these interference mitigation techniques require tight coordination among different RRHs. Parallel Wireless SON coordinates with connected small cells directly, and also provides all required signaling to macro cells and reduces the overall system control signaling. Besides interference issues, the densification of cellular networks can impact user experience due to increases in handoffs and related signaling loads. The increase of handoffs in a mobile system can directly impact the volume of signaling in the system and have a negative impact on overall user experience and system capacity. The Parallel Wireless OpenRAN controller dynamically executes parameter changes to optimize the user experience based on their mobility.
