CommScope’s delivers yet another revolutionary technology with its OneCell platform. OneCell is a unique indoor small cell solution, which utilizes a Cloud RAN (C-RAN) architecture to create a single cell across multiple radios for improved performance and simplified deployment. It consists of a baseband controller and multiple radio points that form a single “super cell.”

OneCell helps operators manage and mitigate interference between small cells and the macro networks in several important ways. Traditional small cells, when densely deployed across a large indoor space, create large areas of overlap between cells. Interference occurs at these borders. Some enterprise small cells use a central service controller to assist with handovers and backhaul aggregation, but it cannot overcome the physics that each cell interferes with its neighbor. Creating multiple independent cells also generates the need for frequent handovers, degrading the user experience in introducing the potential for handover failures or constant back-and-forth handovers between adjacent cells—a phenomenon known as “ping-ponging.”

OneCell creates a single cell that eliminates cell borders altogether. It accomplishes this by centralizing the scheduling of users across the Radio Points. Unlike a service controller, OneCell’s baseband controller performs LTE resource block scheduling centrally across all the radio points and all the users, so it provides a strong signal that is consistent throughout the coverage area—no handovers required.



C-RAN small cells provide capacity benefits beyond those achieved through cell virtualization. In a traditional small cell architecture, each access point provides a fixed amount of capacity for its coverage area. This works well only if usage is evenly distributed across the venue, however this is a condition that rarely holds true. The result is that some access points will be overloaded and others relatively idle. With the OneCell solution, capacity is pooled in the central baseband controller and allocated dynamically to wherever the usage is at any given moment. This makes it possible to handle the natural movement of users throughout an area, and to take full advantage of the system’s capacity. C-RAN also simplifies capacity expansion. With standalone small cells, the only way to add capacity is to add cells—along with the new cell border overlaps that cause interference. With OneCell, capacity can be added centrally at the baseband controller, without creating new cells or cell borders. This new technology will reduce cost of deployment and increase venue appeal, as it is easily integrated into their macro environment.
