Shaping The Industry
Many of InterDigital’s inventions opened the door to new paths in the wireless industry - in many important areas; its history is the history of the industry.
Setting the Framework for Today’s Digital Cellular Networks
InterDigital pioneered wireless TDMA digital voice technologies, setting the framework for mobile wireless digital voice systems, including GSM. InterDigital was early to recognize the advantages of CDMA in wideband channels, which it called BCDMA. Since then, fundamentals of BCDMA have been adopted by WCDMA – “W” for Wideband as the de-facto 3G technology – becoming a “household” term around the world (at least within the industry).
Pushing for the Highest Data Rates Possible
Enter HSDPA and HSUPA (High Speed Downlink/Uplink Packet Access) – pushing 3G data speeds far beyond 2 Mbps. InterDigital’s innovative advanced receiver achieves over 10 Mbps in downlink speeds and improves coverage, especially at the cell-edge. Its HSUPA terminal design similarly pushes towards the highest data rate the network can handle.
Enabling Convergence through Seamless Mobility
Wireless terminals that can connect to a variety of networks - 3G, WiFi, WiMAX – are only just being introduced. InterDigital is already offering solutions for interworking, seamless mobility, and contiguous mobile service today, known as 802.21.
Meeting the Needs of Tomorrow
The company’s sights are now set on wireless networks that provide tens to hundreds of megabits per second, with improved coverage and reliability. To some this is known as 4G, to others Long Term Evolution, requiring new advanced air interface technologies and all-IP networks throughout.
