The article reports that U.S. wireless operators have slowed their adoption of Internet Protocol (IP) Multimedia Subsystems (IMS) with operators inching their way toward the technology through other means that focus on applications and services. IMS brings cellular networks together with other networks running WiMAX, Wi-Fi, cable, DSL and landline. Because IMS requires new network infrastructure, some carriers have been slowing down their rollout plans because of the costs and complexity.
