Who We Are

TFWireless is a semiconductor IP-core startup developing the novel 'FutureG/6G' modem technology, Forward Error Correction (FEC) - Physical Layer Rateless Codec for Satellite Communications (SATCOM).

The startup’s mission is to develop transformative SATCOM modem technology that provides high throughput and coverage, bandwidth gains, high energy efficiency, and a dramatic reduction in costs.

The novel FEC or 6G modem solutions will be offered as custom silicon ASICs, FPGA IP cores, or Software Defined Radios on the edge baseband units depending on the Satellite/Ground segment customer’s needs. We are a fabless semiconductor startup for SATCOM modems.

TFWireless will be a vendor of optical SATCOM modems and a licensor of the PHY layer IP, including patented designs for FEC encoders, decoders, and related baseband blocks of a communication system.

How The 'FutureG' Modem Works

The modems function at leading-edge RF frequencies (Ka-band) and optical 1550nm band wavelengths. The modem designs provide SWaP-C savings opportunities through modular, scalable, miniaturized ASIC/FPGA solutions. The ‘FutureG’ optical modem will be reconfigurable with up to three selectable waveforms.

TFWireless' technical offering is to provide a single, common modem design that could be integrated with a variety of other SATCOM terminal elements (i.e., antennas and amplifiers), which will permit usage of scalable RF/optical power and aperture products. Such a modem design could enable fielding solutions which are scalable in SWaP-C.

The modem will support multiple data rates that scale appropriately with range for the available power and aperture product. A ‘6G’ modem and SATCOM terminal design to support symmetric Mbps/Gbps SATCOM links at LEO range is the notional baseline mode of operation. There will be flexibility in the modem to support multiple data rates that might be as low as 300 Mbps or as high as 20 Gbps using multiple waveforms.

Investors

TFWireless Inc is proudly supported by the National Science Foundation (NSF SBIR/STTR program). The startup is a recipient of the NSF STTR Phase I award as well as the SBIR Phase II award. The seed project of the founder at NASA JPL was funded by the Engineering and Physical Sciences Research Council (EPSRC), UK.

Strategic Partners

The startup is proud to partner with NASA JPL to develop the transformative wireless communications technology with funding from NSF. Specifically, the startup is working with the JPL Section 332: Communications Architectures and Research Section and few other JPL staff to develop the PHY layer rateless codec technology for proximity space links.

Standards

The startup is working to get the PHY layer rateless codec technology for LEO Optical links adopted to the CCSDS standards. The startup is periodically presenting its technology developments to the below working group within the CCSDS Space Link Services (SLS) area:
