InterDigital’s new product strategy


Two years ago, InterDigital was at Mobile World Congress showcasing a new business model, having failed to sell some of its huge portfolio of wireless patents, and decided to rebalance its revenue mix towards consultancy and commercial products. Its bid to harness its significant engineering and R&D resources to generate more products, rather than just licensing opportunities, has started to pay off now, with two spin-offs – XcellAir and – featuring on the company’s stand in Barcelona, along with other inventions which could well make the same leap towards independence.

The heart of the company has always been the R&D effort, which centers on a Labs unit with about 200 engineers. Traditionally, the inventions were mainly harnessed for licensing revenues, which historically accounted for around 90% of the total, with the company creating 95% of its patents via inhouse developments. So it has always had the potential  to productize them, but this has been a “bumpy” business in the past, according to the company’s EVP of R&D, Jim Nolan. The goal, set in 2012, was to make product revenues more consistent, often through spin-offs or partnerships with firms with greater experience of bringing offerings to market.

That thought process means taking a technology emerging into the mainstream and looking at ways to commercialize it in future, far beyond one or two applications, “thus maximizing the reach of any inventions, both in patent licensing and partnership terms”. Much of the firm’s work relates to the evolution of the ‘network of networks’ in which there is seamless connectivity between huge numbers of different protocols, device types and spectrum bands, right out to the internet of things.

Four particular areas of interest chosen by Nolan’s organization were bandwidth management and smart access; dynamic spectrum management; M2M; and advanced video research. In all four, there should be near term opportunities to bring products to market, generally through alliances, but also a development path stretching well into the future.

XCellAir fits clearly into this framework, emerging from stealth mode this year with a cloud-based management and optimization platform that supports HetNet SON and has an evolution path towards dynamic bandwidth management and network-as-a-service. It is targeting cellcos and MVNOs, as well as ISPs and cablecos with WiFi assets.

Building on InterDigital projects in its four key areas, the platform will embrace many fashionable aspects of modern networks – NFV virtualization, orchestration for SDN, radio resource management, analytics and capacity management, all of which can be delivered from the cloud to enable new hosted services. Some of the elements, such as WiFi SON (self-optimizing networks) are homegrown, while others rely on partner, such as LTE SON (AirHop) and the actual access points (GoNet Systems, maker of high end WiFi APs based on MIMO and beamforming).

The new firm is headed up by Narayan Menon, formerly VP of R&D at InterDigital, and Amit Agarwal, formerly general manager at Radisys (which has also provided other executives including sales and marketing chief Todd Mersch).

The other spin-out is, which provides a data service exchange for smart cities, and was showing a transportation demonstration, in partnership with Stream Technologies’ IoT-X unified access connectivity platform.

Meanwhile, InterDigital itself also showed off its WiGig-based mesh backhaul solution, EdgeHaul; a software development platform compliant with the oneM2M standards; the Smart Access Manager application for dynamic policy-based WiFi network selection and analytics; and the Perceptual Pre-Processing system, which filters out parts of visual content that the human eye cannot see under certain viewing conditions to save bandwidth in HD video applications.
