Wireless Radio Module for Industrial Mesh Wi-Fi Routers

Product Specifications

Technical details and manufacturing context for Wireless Radio Module

Definition

This wireless radio module is a component used in the manufacturing of computer, electronic, and optical products, specifically designed for integration into devices such as industrial-grade mesh Wi-Fi routers. It functions as the primary interface for wireless data exchange, handling the generation, modulation, transmission, reception, and demodulation of radio frequency (RF) signals. The module converts digital data from the router's main processor into analog RF signals using modulation techniques like OFDM or QAM, amplifies and transmits them via an antenna, and conversely receives incoming RF signals, filters noise, demodulates them, and passes the digital data back to the processor for network routing and management.

Key parameters for this module include a frequency range of 2.4–2.4835 GHz (ISM band for Bluetooth, Zigbee, Wi-Fi, per IEEE 802.15.1), transmit power of 0–20 dBm (per ETSI EN 300 328), receiver sensitivity of -120 to -90 dBm, data rates of 1–250 kbps, operating voltage of 1.8–3.6 V DC, current consumption of 10–100 mA in transmit mode and 5–30 mA in receive mode, and an operating temperature range of -40 to 85°C (per IEC 60068-2-1). It supports UART, SPI, and I2C interfaces, and offers antenna options including PCB, SMA, and IPEX. Physical dimensions range from 10–30 mm in length and width, with a weight of 1–5 g.

Materials typically include a printed circuit board (PCB), RF integrated circuit (RFIC), crystal oscillator, passive components (resistors, capacitors, inductors), and an antenna connector. These specifications are reference ranges; actual values must be confirmed with the manufacturer for the specific model and application. The module is intended for use in industrial environments, and compliance with relevant standards should be verified with the supplier.

Working Principle

The module operates by converting digital data from the host processor into analog RF signals through modulation (e.g., OFDM, QAM). These signals are amplified and transmitted via an antenna. In reception, incoming RF signals are captured, amplified, filtered to remove noise, and demodulated back into digital data, which is then sent to the processor for network handling. The module's performance depends on parameters such as frequency, power, sensitivity, and data rate, which must be matched to the application's requirements.
