IP Multimedia Subsystem Networks

IP Multimedia Subsystem (IMS) is about to revolutionize the telecom market. According to ABI Research analyst Ian Cox, "Every Tier 1 service provider in fixed and wireless networks will announce SIP-based services running over IMS in the next six to twelve months." IMS began life as a wireless network architecture for adding IP-based services to existing circuit-switched voice. When Session Initiated Protocol (SIP) was introduced, IMS evolved to an open architecture: operators are not locked into a proprietary solution, nor are point solutions needed for each service. Soon fixed network providers began adapting it to IP networks. IMS allows a single device to use both fixed and wireless networks. IMS will allow many new services, including VoIP, to be offered simultaneously over SIP-enabled networks. Vendors can develop applications and equipment knowing they will be fully interoperable. Services can be tried quickly and discarded if unpopular. A single database holds all subscriber information, lowering operating costs for multiple services.

When AI Spending Reaches $3.6 Trillion

Enterprise AI budgets are flowing in two directions at once, and only one of them builds an asset the buyer actually controls. Gartner's latest forecast puts worldwide AI spending at $2.7 trillion in 2026, but the composition of that figure matters far more than the total. Executives who read only the headline will miss the tension between what they are buying and what they actually own. The Number Behind the Number Gartner projects 2026 AI spending is a 49.5 percent increase over 2025, with $3.6 trillion forecast for 2027. AI infrastructure accounts for $1.5 trillion of this year's total, more than half. Gartner's John-David Lovelock calls the data center buildout the largest infrastructure project humanity has undertaken, and describes demand as inelastic even as memory prices climb. Compute Concentration is a Sovereignty Issue Gartner expects hyperscalers and service providers buying AI-optimized servers to remain the largest single area of spending. For an enterprise, t...
