Wireless technologies comjpany InterDigital and embedded media centric systems firm Ittiam have developed a system to extend Wi-Fi technology into TV White Space (TVWS) and other underutilized frequency bands. Integrated Dynamic Spectrum Management (DSM) technology harvests TVWS and other available frequency channels to increase the data throughput of Wi-Fi devices, addressing the congestion of heavily-used unlicensed bands and the ever-growing demand for wireless bandwidth.
InterDigital develops and standardizes DSM technologies that enable Wi-Fi, LTE and other wireless communications over TVWS and other under-utilized frequency bands. The technologies can be integrated into wireless terminal devices or infrastructure platforms such as e.g., access points, pico/femto/ metro base stations, home gateways and set top boxes to provide additional wireless broadband capacity when traditional networks are saturated.
Ittiam is a leading provider of Wi-Fi (802.11a/b/g/n) technology with single stream and MIMO solutions that power a range of products. The Ittiam MWLAN platform provides the Wi-Fi MAC and Physical Layer for InterDigital’s Dynamic Spectrum Management demonstration that includes:
• allocation and aggregation of contiguous and non-contiguous frequency channels across licensed, unlicensed and TVWS
• database and sensing-assisted spectrum allocation
• extension of legacy systems such as Wi-Fi and cellular into under-utilized frequency bands
“Ittiam invested in the Wi-Fi Silicon IP over a decade ago with full understanding that all consumer devices will one day get to the ‘always connected’ mode using Wi-Fi,” said Ravishankar Ganesan, Vice President and Head of SOC IP Business Unit, Ittiam Systems Pvt. Ltd.
“Intelligent harvesting of under-utilized spectrum is a key approach towards solving the bandwidth crunch in wireless networks. Ittiam’s Wi-Fi technology, extended to operate and aggregate channels in TV White Space bands, is an important component of our solution,” said James J. Nolan, Executive Vice President, Research and Development, InterDigital Inc.
