Product Description

The transceiver is bi-directional highly integrated, cost-effective, smart radio, sub-1 GHz wireless node solution pre-programmed with NB-Fi protocol stack. NB-Fi protocol provides link budget up to 180 dBm @ 15 dBm transmitter power.

The highly integrated RF transceiver operates over a wide frequency range including 315 MHz, 433 MHz, 470 MHz, 500 MHz, 868 MHz, 915 MHz in the license-free Industrial, Scientific and Medical (ISM) frequency bands. This configuration allows a user to minimize the use of external components.

Key benefits

    • QFN40 package
    • Best radiomodule for smart metering applications
    • 16+ km in harsh city environment, 50+ km in rural area
    • 20 years on AA battery
    • Low power is not sacrificing link budget
    • Ultra low power wake-on-radio mode
    • Data rate 10-100 bps via NB-Fi
    • Low RX current of 9.5 mA
    • Supply range 1.8 V – 3.6 V
    • Operating temperature -40 °C to 85 °C
    • Sleep mode with RAM retention and wake-up timer running 1.5 μA
    • Temperature sensor
    • Long-range wireless NB-Fi protocol
    • Uplink sensitivity -152dBm @ 12 bps effective data rate
    • Downlink sensitivity -148dBm @ 12 bps effective data rate
    • In practice, downlink equals to uplink because of extra noise on gateway level
    • 5 000 simultaneous channels on a base station level
    • 50 000 simultaneous demodulations on a base station level
    • Sending and receiving messages via AT commands

The serial interface is designed to operate using protocol parameters: UART, LVTTL electrical level, 115200 bps, 8 data bits, 1 stop bit, no parity.
