This is an important portfolio for companies involved in mobile and network communications wishing to provide seamless, high-quality products and services to their users," says Dean Becker, CEO of ICAP Patent Brokerage. Since 1985, Roke Manor Research Limited has played a pivotal role in the development of cellular communications systems, including the GSM telecommunications standard, GPRS, and UMTS. Key Characteristics & BenefitsThe portfolio for sale includes improvements for data compression and routing, including buffer management techniques and switching devices. Third and fourth generation mobile handsets require improved management of data packets to provide greater bandwidth for seamless email, browsing, and media services without compromising on speech quality. Likewise, there is an urgent demand for improved routing of network traffic to accommodate the extremely large and growing aggregate bandwidth requirement. This IP package offers innovative reassembly buffer management techniques, including methods of compression and subsequent decompression of headers and characters of binary data units. Further, an improved version of the Huffman coding method is described, which has significantly lower memory requirements than ordinary Huffman and is applicable to more generic data types, such as packet headers, where it can give a better compression ratio. The portfolio also includes improved switching devices, specifically a system for providing distributed schedules for such devices. A technique for transmitting control information across a switching device is described, as well as cross-bar switches having a cell-level scheduling scheme for handling multicast traffic and a method of adjusting bandwidth in such devices.
