About The Team

Tejas Networks is driving cutting-edge research to revolutionize content delivery and wireless communication technologies. One major area of focus is the development of advanced solutions that integrate broadcast and cellular networks to enable seamless content distribution. These innovations aim to alleviate network congestion, reduce infrastructure costs, and enhance the overall user experience. A key outcome of this work is a next-generation Content Delivery Network (CDN) architecture that supports Direct-to-Mobile (D2M) delivery, developed in collaboration with leading CDN and content providers. This initiative is backed by a robust portfolio of patented technologies in broadcast and content delivery systems.

In parallel, significant efforts are being made to enhance the flexibility and efficiency of wireless network operations. Research in this domain includes the creation of a domain-specific language (DSL) that enables platform-independent expression of Radio Access Network (RAN) functions, helping reduce dependency on proprietary hardware. Additionally, advanced AI/ML techniques are being employed to automate network management, streamline operations, and optimize resource utilizationresulting in substantial cost savings and improved performance. These contributions have led to multiple patents and active participation in international standardization efforts.
