MUMBAI, India, Nov. 28 -- Intellectual Property India has published a patent application (202411026087 A) filed by Frog Cellsat Limited, Noida, Uttar Pradesh, on March 29, 2024, for 'terrestrial trunked radio (tetra) distributed antenna system (das).'
Inventor(s) include Konark Trivedi; Rajnish Narayan; Rajneesh Kumar Verma; Chandraprakash Nautiyal; and Satish Chaurasiya.
The application for the patent was published on Nov. 28, under issue no. 48/2025.
According to the abstract released by the Intellectual Property India: "A Terrestrial Trunked Radio (TETRA) Distributed Antenna System (DAS), comprising a first Radio Frequency (RF) transceiver chip, a second RF transceiver chip, where each of first RF transceiver chip and the second RF transceiver chip is configured to transmit and receive one or more RF signals within TETRA frequency bands, a Field-Programmable Gate Array (FPGA) communicatively coupled to the first RF transceiver chip and the second RF transceiver chip, where the FPGA comprises a channel filter bank configured to electronically filter one or more channel bandwidths within a predefined configurable bandwidth range. The TETRA DAS comprises a microcontroller communicatively coupled to the FPGA via at least one communication interface, where the microcontroller is configured to execute a dynamic spectrum allocation by dynamically controlling and tuning electronic channel filtering operations of the first RF transceiver chip and the second RF transceiver chip based on a real-time or near real-time network condition."
