The technology industry continues to be a hotbed of innovation. Activity is driven by the rapid emergence and widespread adoption of game-changing technologies such as artificial intelligence (AI), internet of things (IoT), and mobility, and growing importance of technologies such as virtual private network, multiprotocol label switching, traffic optimisation and prioritisation, and centralised management and orchestration. In the last three years alone, there have been over 3.6 million patents filed and granted in the technology industry, according to GlobalData’s report on Innovation in Cloud: Software-defined WAN. Buy the report here.

According to GlobalData’s Technology Foresights, which uses over 2.5 million patents to analyse innovation intensity for the technology industry, there are 300+ innovation areas that will shape the future of the industry.

Software defined WAN is a key innovation area in cloud

Software-defined wide area networking (SD-WAN) is a network architecture that employs software-defined networking (SDN) to efficiently direct traffic across wide area networks (WANs). SD-WAN is specifically designed to enhance the agility, flexibility, and manageability of WANs. It offers businesses a cost-effective solution for connecting their branch offices, remote sites, and cloud applications in a streamlined manner.

GlobalData’s analysis also uncovers the companies at the forefront of each innovation area and assesses the potential reach and impact of their patenting activity across different applications and geographies. According to GlobalData, there are 190+ companies, spanning technology vendors, established technology companies, and up-and-coming start-ups engaged in the development and application of software defined WAN.

Key players in software defined WAN – a disruptive innovation in the technology industry

‘Application diversity’ measures the number of different applications identified for each relevant patent. It broadly splits companies into either ‘niche’ or ‘diversified’ innovators.

‘Geographic reach’ refers to the number of different countries each relevant patent is registered in. It reflects the breadth of geographic application intended, ranging from ‘global’ to ‘local’.

Huawei is one of the leading patent filers in software defined WAN. The company’s patents are aimed at a method for reporting channel state information, including receiving a sounding signal set sent by the base station, and determining a reference signal resource configuration index according to the sounding signal set, where the reference signal resource configuration index is used to indicate a reference signal resource configuration in reference signal resource configuration set information.

The method also includes receiving a reference signal set sent by the base station, where the reference signal set corresponds to the reference signal resource configuration and determining channel state information according to the reference signal set, as well as sending the reference signal resource configuration index and the channel state information to the base station.

Other prominent patent filers in the space include Qualcomm and LG.  

By geographic reach, CSR leads the pack, followed by Neul and Wireless Future Technologies. In terms of application diversity, Infineon Technologies holds the top position, followed by Dolby Laboratories and PHC.       

SD-WAN offers significant benefits to businesses, including increased agility, improved network performance, cost efficiency, simplified management, enhanced security, and optimised cloud connectivity. By leveraging SD-WAN, businesses can build resilient and scalable networks that support their digital transformation initiatives and meet the demands of the modern business landscape.
