Protostellar systems are characterized by the interplay between mass accretion and mass ejection, shaping the evolution of protostars. Jets and outflows play a crucial role in driving the material dynamics in these systems. They can be probed at various frequencies, offering insights into locations, timescales, and physical processes. Observations of compact thermal jets at radio wavelengths can probe the base of the jet close to the driving source, providing a unique opportunity to study the morphology, structure, and physical conditions of protostellar jets near the launching point. Most such studies, however, are done at higher radio frequencies (> 3 GHz). We have carried out a low radio-frequency survey of jets in protostars that are observed with JWST as part of a Cycle 1 GO program "Investigating Protostellar Accretion (IPA) across the mass spectrum" using the upgraded Giant Metrewave Radio Telescope (uGMRT). The IPA sources have luminosities ranging from 0.2 to 10,000 solar luminosities and masses from 0.12 to 10 solar masses. Combining our observations with the high-frequency archival data, we have constructed spectral energy distribution to derive the physical parameters such as mass loss rate, injection radius, and turnover frequency. Our uGMRT observations will provide ionic mass loss rates, which we will compare with that derived from JWST observations. We will present our results and discuss their implications.
