Seamless Connectivity Across Different Air Interfaces
The growing demand for mobile broadband services is the catalyst for an ever-increasing variety of air interface technologies targeting local area to wide area connectivity. We envision that the network of tomorrow will be a “network of networks” that enables uninterrupted services when roaming across many different independent radio access solutions – a mega network transparent to the users.
InterDigital has been a pioneer in the development of Media Independent Handover (MIH) and helped define the IEEE 802.21 standard for seamlessly connecting GSM, WCDMA, WiMAX, WiFi, cdma2000, and virtually any other radio access technology. In practical terms, MIH technology provides operators with a virtual network extension and a platform for a range of new services– with minimal investment and low technical complexity – offering a better user experience with increased reliability and transparent coverage.
A typical MIH solution consists of a simple MIH client in the mobile device, an MIH server in the IP backhaul and requires no changes to the existing radio access network. Our seamless connectivity roadmap is rapidly evolving to enable additional services and capabilities that include LTE, IMS, Mobile TV, and Cognitive Radio.
