But... How about the -4i dB/Mhz Tx requirement? The energy per bit is lower than BLE, but the overall transmit power limitations are just going to limit the adoption. We created an in-house developed (Qorvo based) a solution for audio several years ago (192K x 32 bit [uncompressed]) but the basic RF issues are not easily overcome. As the owner of a property protocol for audio over UWB (and being a well known microwave antenna design house), I should be touting this technology but experience has made my team and I far more schooled on the basic limitations of UWB. I guess the ultimate signal of the failure of UWB is that even Apple has scaled back their UWB audio plans, as has Huawei, Oppo and Vivo.
