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.
The industrial sector is on the eve of a wireless transformation, driven by an urgent demand for greater network capacity, reliability, and deterministic performance. Historically, manufacturers and mission-critical operations have relied on wired networks — favoring their predictability — because spectrum congestion in legacy 2.4GHz and 5GHz bands limited confidence in wireless for operational technology (OT) environments. However, with the introduction and rapid adoption of the 6GHz spectrum, compounded by significant advances in Wi-Fi standards, industrial facilities are now poised to embrace wireless LANs as the backbone for automation and digital innovation. Industrial WLAN Market Development Recent research from ABI Research forecasts that over 70 percent of industrial-grade wireless LAN access points (WLAN APs) shipped in 2030 will support the 6GHz band. This is a leap from 2 percent in 2023, highlighting a rapid and profound technological shift. The market for ruggedized indust...
