Global mobile network infrastructure spending will peak at approximately $92 billion in 2026–2027 before declining 29% to $65 billion by 2031, according to ABI Research’s Indoor, Outdoor, and IoT Network Infrastructure report published March 26, 2026. The drop signals the end of the 5G buildout cycle and the beginning of a transitional period where operators must deliver more capacity with dramatically less capital — a shift that directly reshapes the career trajectory of every service provider network engineer. ...

Samsung and AMD have officially expanded their strategic partnership beyond the Radio Access Network into 5G Core, private networks, and edge AI — marking a pivotal shift from lab verification to commercial deployment. Announced at MWC 2026 in Barcelona, this collaboration now puts AMD EPYC processors at the heart of Samsung’s entire telecom software stack, delivering commercial-grade AI-powered vRAN performance without dedicated hardware accelerators. For service provider engineers, this signals that cloud-native, software-defined architecture is no longer a future roadmap item — it is the production reality operators are deploying today. ...

The CCIE Service Provider track is not dying — it’s evolving. In 2026, SP engineers who combine deep telco expertise with cloud networking skills are earning $180K-$220K, outpacing both pure telco and pure cloud specialists. The real career question isn’t “telco or cloud?” — it’s “how do I become the engineer who bridges both worlds?” Key Takeaway: Don’t abandon your SP skills for a cloud pivot. The highest-value network engineers in 2026 are hybrid architects who understand both carrier-grade MPLS/Segment Routing infrastructure and cloud overlay networking — and the market is paying a premium for that combination. ...

AT&T just showed network engineers what the future of carrier networks looks like — and it’s not just about moving packets. At MWC 2026, AT&T launched Connected AI for Manufacturing, a platform built with Nvidia, Microsoft, and MicroAI that pushes AI inference from the cloud to the factory floor over 5G. For network engineers, this is the clearest signal yet that telcos are evolving from connectivity providers into AI infrastructure platforms. ...
