MN L2 SW1 KRK & MN L2 SW2 KRK
Layer 2 is the brain behind 5G technology. Programmers from our department co-create the software responsible for transmission of data packets over the cellular network in this latest mobile technology. Our software makes decisions within milliseconds about granting access to the medium to dozens of phones simultaneously. We develop it in C++ technology, at the same time integrating with hundreds of commits from this and other components every day. Apart from writing code, our programmers create component tests, take part in peer-reviews, create scrum teams and virtual teams (feature teams) focused on delivering new functionalities for tens of thousands of base stations used by telecom operators around the world. All this so that smartphone users, automated industrial systems, and Internet of Things devices can enjoy even faster and more reliable data transfer using 5G networks.
MN L3 SW2 KRK
Layer 3 (L3) or Control Plane is the control layer of the 5G base station (gNB) responsible for handling connections made by subscriber devices (e.g. smartphones), their configuration and management (e.g. ability to move between base stations). Our engineers co-create both requirements and software, as well as tests (unit, component, functional) needed to deliver new functions to operators. Additionally, we provide technical support for customers in the implementation of our solutions. We create and develop software for base stations in C++ language. For testing we use languages such as Python/C++/TTCN-3. For managing changes in software we use a wide range of tools, including Git/Gerrit/Jenkins/Jira. We develop our software iteratively based on Agile/Scrum methodology.
We have a well-developed implementation program in our teams that allows us to quickly start working independently.
MN RF RD PL
MN RAN L3 SIM KRK
Our engineering group, codenamed 'L3 SIM ’, develops and tests software in mobile base stations, primarily responsible for setting up calls to and from phones, both in LTE and 5G standards. For software testing we use simulators of other mobile network elements, with which base station cooperates. Some of the engineers on our team work on developing these test tools, hence the name 'SIM’ in our engineering group name. We develop simulator products needed to simulate user terminals (User Equipments), radio heads (Radio Units) and entire cellular network elements (gNB, eNB, MME, PGW, SGW, eNB).
Layer3′ in the name is a code abbreviation for the layer that controls the connection establishment process, i.e. Control Plane. The layer controlling 5G (gNB) and 4G (eNB) base stations deals with configuration and management of connections with subscriber devices (smartphones, IoT devices, etc). Our engineers co-develop requirements and software, as well as tests (unit, component, functional) needed to deliver new features to operators. Additionally, we provide technical support to customers in the implementation of our solutions.
At work, our engineers use software languages – primarily C++/Python/TTCN-3/Erlang. We use tools such as Git/Gerrit/Jenkins/Jira to manage software changes. We develop our software iteratively based on Agile/Scrum methodology. In our team we have engineers with different seniority, from telecom veterans with 10 or 20 years of experience to recent hires. Our teams have effective induction programs in place for new employees allowing them to quickly start working independently.
MN RF Pz Product CI
MN RF Pz Product CI is responsible for Nokia Radio products, RF integration and verification in particular for integrating and verifying software packages consisting of different components like RFSW, L1-Low SW and SoC. To ensure expected quality of software and hardware and meet customer deliveries we focus on full test automation. We mainly use Python for test integration and automation and different supporting tools like Git, Gerrit, Jenkins or Jira. We operate in Agile methodology tailored to big scaled teams. We also support customer teams and provide fast response should any issue in the network occur. We also have well established on boarding program for new engineers.
