Private Campus Networks offer operators a significant opportunity for value generation, with a global market size estimated to reach €60-70bn by 2025. However, operators risk missing out if they do not act now and prepare accordingly. Enterprises have economically sensible use cases and technologically justified needs for private 5G or LTE technology on their premises, but few operators have developed a strategic approach to satisfy this demand. Regulators are demonstrating a willingness to listen and auction spectrum locally, while new disruptive players are emerging with simple network solutions. These developments are paving the way for enterprises to source private networks without operator involvement. Operators should fully embrace this opportunity and formulate a more industrialized approach to campus networking.
