IEEE 802.11ah Wi-Fi Solution in TVWS bands + MCU SoC

![icon](https://newracom.com/hubfs/Newracom_2022/Images/Product_Inner/icon.png)

#### Overview

As an optimized Wi-Fi solution for internet of things (IoT) devices, NRC4792 is the industry’s first single system on a chip (SoC) that fully integrates digital baseband modem and RF transceiver, operated in the UHF TVWS bands. NRC4792 offers a much greater range of coverage and efficiency in power consumption over 2.4GHz and 5GHz. Particularly compared with conventional HaLowTM, it also provides with better channel bandwidth for more higher and secure data transmission in case of the lack of bandwidth in specific regions. By complying with IEEE 802.11ah standard and supporting 1/2/4MHz channel widths with optional short guard interval (SGI) yield 150 Kbps to 15 Mbps PHY throughput which can support low-rate sensor to high-rate surveillance camera application.

Various power-saving features enable a longer sleep time to greatly reduces power consumption and hence increase battery life. Besides, the capability to obtain surrounding channel information from a geolocation database with the addition of a supplementary spectrum sensing function enables the chip to find the best available channels in an operation site.

The internal power management system provides for the power required inside the chip and therefore allows the chip to operate with a single power input. In addition to this system, the fully integrated RF transceiver simplifies the circuit, minimizes the PCB size, requires minimal external components, and enables fast time-to-market.

The RF transceiver is a complete radio front-end optimized for TVWS band and it has fully integrated pre-power amplifiers as well as the capability to support various commercial external FEM device. NRC4792 can be used either as a standalone device or a slave to a host processor via serial peripheral interface (SPI) or universal asynchronous receiver transmitter (UART) interface. In addition, it can support both AP and STA roles.
