Baseband & SoC

is a department dealing with the development of System Modules constituting a part of the infrastructure that forms the Base Transceiver Station of the cellular network. Our key tasks include creating a platform on which various radio access technologies are implemented (2G, 3G, 4G, 5G). The platform includes hardware components (HW), System-on-chip (SoC) and software components (SW).

RF

is a part of Nokia Radio Frequency and Advanced Antennas organization. We are responsible for specifying, designing, implementing, testing and maintaining radio products’ software for various radio access technologies, including GSM, WCDMA, LTE and 5G.  As a tribe we are divided into self-organizing teams, working in an Agile environment. Our products are developed mainly in C++ and C on several software architecture layers, including those close to hardware, as well as on higher levels of abstraction. At this point we have almost 500 engineers working in Wrocław and Kraków locations. We maintain very close cooperation with sites in USA, Finland, China and Romania. As an organization, we are responsible for our products’ integration throughout the whole product life cycle, which is performed in the automated Continuous Integration environment.
A common and clearly defined vision, open communication and a deep passion for innovation are the features that best describe our work environment and its unique atmosphere. We believe these are the values that shape the future of technology

L3

is a part of a large project that’s being developed by several sites from different parts of the world (Poland, US, Finland, Germany, France, and China). Our journey started in 2009 with LTE. Since then our team has grown to over 200 people. Currently we are actively contributing to both 4G and 5G projects, creating the cutting-edge technology that revolutionize nearly every aspect of our everyday lives.

BTS OAM

(Base Transceiver Station Operations, Administration and Maintenance) development unit is responsible for designing, providing and delivering software for base stations that support many radio technologies simultaneously, including CloudBTS and 5G, which is a revolutionary solution in the world of mobile telecommunications.
Remaining in line with the latest trends towards cloud solutions, the department is focused on virtualization of solutions to facilitate the management of network infrastructure through greater scalability and reliability as well as to support the faster implementation of new products. The software created by BTS OAM is also used to develop new technologies, i.a. 5G and Telco cloud. In this department, the base station management interface is developed. Additionally, there are supporting tools created for internal organization needs but also for whole MN.

L1

is responsible for delivering world-class implementations of physical layer DSP algorithms for 4G and 5G mobile technologies. L1 contributes to both traditional users’ and Internet of Things (IoT) devices’ reception. Their own System Component Test environment is written from scratch in Python. All their software is hard in Real-Time. The hardware platforms we work on range from specialized Digital Signal Processors to General-Purpose Processors.

Software Configuration Management (SCM)

Software Configuration Management deals with software development and associated automation of building processes at all levels of the mobile networks base station software. Both its individual components and the final comprehensive software installed on the base stations are supported. We work on product environments for various HW architecture variants used in technologies such as LTE, SRAN, WCDMA, and 5G. SCM ensures software integrity, repeatability of its building processes and availability of correct configuration. We create and maintain Continuous Integration pipelines for MN RAN software products.
