About the Team The Radio Software Team is Modern eNodeB (4G LTE Radio) or gNodeB (5G NR Radio) are key elements of mobile Telecom network. These radios are realized in different ways Standalone Radio , BBU (Base Band Unit) and RRH (Remote Radio Head), O-RAN CU (Central Unit) DU (Distributed Unit) and RU (Radio Unit). In deployments RU/RRH are deployed on top of the tower and BBU/CU-DU at bottom. The RU/RRH key functionality is to convert base band signals to RF and also amplify signal to higher power. Tejas Networks has invested in Wireless product development since 2012 with a vision to create globally deployable telecom RAN solutions. Several of the key components developed by the Wireless R&D team have been installed and commissioned across three continents. We are an active partner for 5G in the Indian Ecosystem and have significantly contributed to India’s standardization efforts in 3GPP, through TSDSI. The wireless team has over 100 patents.
