InnoPhase’s Low-Power Wi-Fi Transceiver Puts Battery-Powered Devices at the Edge of the IoT

July 29, 2019 Rich Nass

The term “low power” is very subjective and depends on a host of factors. For example, a low-power medical device like a pacemaker may run for 10 years without needing a battery replacement. But a low-power rack-mounted system may be pulling in hundreds of watts, but it’s still “low power” relative to what competitive products offer.

That said, the “low-power” Talaria Two platform, developed by InnoPhase, clearly meets the criteria compared to competitive devices. Aimed at the battery-powered IoT sector, this single-chip Wi-Fi radio contains a full-functional multiprotocol transceiver, a MAC/PHY, a digital power amplifier, and an embedded ARM processor with enough headroom for lightweight applications.

The Talaria Two platform uses the company’s patented PolaRFusion radio architecture, which processes radio signals using polar coordinates rather than traditional IQ coordinates. This digitally-intensive radio solution reduces the amount of power required to transmit, process, and receive wireless information using industry standard wireless protocols by as much as 50 percent. It achieves this by moving most of the radio signal processing from traditional higher power analog circuitry into more efficient digital logic.

Maximum flexibility is achieved by actively managing multiprotocol coexistence for 802.11b/g/n and BLE 5.0 for applications at the Edge of the IoT, such as cameras, audio devices, and other smart sensors. The part is sampling now, moving to production shortly.
