Global Capability Centers in Telecom

AT&T is an American multinational telecommunications conglomerate headquartered in Dallas Texas. It is the second largest wireless carrier in the United States providing wireless local exchange long distance data broadband and video services. It has 133030 employees and earned 125.6 billion dollars in 2025. Its India Development Center delivers software engineering AI and network solutions.

Deutsche Telekom AG is a leading telecom company headquartered in Bonn, Germany, providing 5g, network infrastructure, mobile services solutions globally.

Ericsson Global India in Gurugram is one of the country's most significant telecommunications technology GCCs, with approximately 20,000 engineers contributing to the development of the radio and core network software that powers 5G deployments globally. Established in 2001, the India engineering organisation has grown into Ericsson's largest engineering presence outside Sweden and the United States, working on the full stack of telecommunications infrastructure software — from radio access network algorithms to cloud-native network core functions, OSS management, and AI-powered network analytics. The 5G software engineering work at Ericsson India is technically deep and globally impactful. Radio access network software teams write the signal processing algorithms and protocol implementations that determine how efficiently Ericsson's 5G base stations use radio spectrum — a domain requiring advanced mathematics, real-time programming in C/C++, and deep knowledge of telecommunications standards. Cloud-native network functions development is a growing priority, as operators globally demand software that can run on commodity cloud infrastructure rather than Ericsson-proprietary hardware, enabling more flexible and cost-efficient network deployment. Ericsson India targets 22,000 employees by 2027, with growth in 5G core engineering, cloud-native networking, and AI for network intelligence. The Gurugram campus in DLF Industrial Area provides a well-established engineering environment, and Ericsson's position as one of only three credible global 5G infrastructure vendors gives India engineers a rare opportunity to work at the frontier of telecommunications technology with direct global market impact.

Ericsson's Polish operations span Krakow and Lodz, with approximately 1,800 engineers focused on 5G network software and cloud-native telecom solutions. The center has been a key contributor to Ericsson's global 5G product portfolio since 2001. Engineering teams work with Java, C/C++, Python, and Go on mission-critical telecom infrastructure. The center leverages Kubernetes for network function virtualization. With 100 patents filed, the center makes significant IP contributions. Ericsson's presence has helped establish Krakow as a telecom R&D hub alongside Nokia. The expansion to Lodz demonstrates the company's continued investment in Poland's engineering talent.
