Amarisoft public and private networks

Overview

In the market for 4G and 5G network deployment, Amarisoft plays a crucial role as a technology provider rather than an infrastructure vendor. Over the past decade, Amarisoft has successfully developed an extensive ecosystem with more than 40 infrastructure vendor partners. These partners leverage Amarisoft's technology to deliver a diverse range of products and services that cater to the demands of this dynamic market.

Amarisoft's vRAN eNodeB gNodeB, featuring open split 8 or split 7.2 APIs, is seamlessly integrated by our partners with high-power radio front ends. This integration allows for the creation of versatile RAN products, including macro base stations, small cells, femto cells, network-in-a-box solutions, and more.

In private network projects, our partners also utilize Amarisoft's 4G and 5G core network, further contributing to the comprehensive solutions provided by Amarisoft and its network of partners.

Architecture

Amarisoft's innovative technology facilitates the expeditious advancement of roadmaps, enabling the swift development of both public and private network products and services. The ensuing examples showcase architectural configurations for base stations utilizing Amarisoft's cutting-edge vRAN technology. These configurations serve as illustrative models, highlighting the versatility and adaptability of Amarisoft's solutions in constructing robust and efficient communication networks, whether for public infrastructure or tailored private deployments.

In this illustration, the BBU (Baseband Unit) functions as an x86 Linux machine equipped with Amarisoft gNodeB software. It's noteworthy that no acceleration is required in this setup. The entire gNodeB, encompassing the physical layer, operates purely as software on the CPU. The exchange of IQ samples in the time domain between the gNodeB software and remote radio heads is achieved through a CPRI card connected by fiber cables. The driver associated with this configuration enables seamless adaptation to various radio vendors' CPRI protocols.

100 MHz 4T4R small cell example

In this example, the BBU (Baseband Unit) operates as an ARM Linux machine running Amarisoft gNodeB software. It's essential to highlight that no acceleration is required in this context. The complete gNodeB, inclusive of the physical layer, operates entirely as software on the CPU. The interface between the motherboard and the radio front end utilizes PCIe, although other interfaces such as USB or Ethernet are also viable options. Additionally, in certain scenarios, our partners deploy the core network, transforming the small cell into a comprehensive network-in-a-box solution.

Software components

vRAN eNodeB gNodeB

A release 17 full software eNodeB gNodeB including layer3, layer 2, layer1 and physical layer. It connects to a split 8 or split 7.2 radio front end through an open API via a driver. It supports a standard S1/NG interface to connect a 4G or 5G core network. The eNodeB gNodeB is configurable through hundreds of parameters in a text file in JSON format. It has a WebSocket API for automation, and a command line interface. Technical doc
