INTRODUCTION
The Sparkercomm Bell N Series Baseband Unit (BBU) is part of a high-performance 5G NR distributed base station solution, which consists of one 5G BBU and one or multiple 5G Remote Radio Units (RRUs). The product can be deployed indoors and outdoors as a low-cost solution that improves wireless coverage range and capacity.
The Bell N Series BBU supports Global Navigation Satellite System (GNSS) synchronization. It supports communication to other modules using optical fiber or photoelectric hybrid cable. It is built using established technology that provides high reliability, easy deployment, and flexible configuration, making it suitable for various indoor and outdoor scenarios.
The Bell N Series BBU’s software is based on 3GPP Release 15, which includes the User Plane (UP) and Control Plane (CP) processing functions. It provides the backhaul (NG interface) with the core network and the interconnection (Xn interface) between base stations.
This product has a standard one-year warranty. An extended warranty is available.
