Product Description

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

Key benefits

    • QFN28 package, 6x6mm
    • Best radiomodule for smart metering
    • 16+ km range in harsh city environment
    • 20 years on AA battery
    • NB-Fi narrow band protocol
    • Low power is not sacrificing link budget
    • Ultra low power wake-on-radio mode
    • Data rate 10-100 bps via WAVIoT
    • Low RX current of 9.9 mA
    • Supply range 2.5 V – 3.3 V
    • Operating temperature -40 °C to 85 °C
    • Sleep mode with RAM retention and wake-up timer running 1.0 μA
    • Temperature sensor
    • WAVIoT NB-Fi proprietary radio protocol and LoRa
    • Lora downlink sensitivity -148 dBm @ 11 bps effective data rate
    • On practice downlink is close to uplink because of extra noise on gateway level
    • 5000 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 serial protocol parameters: UART, LVTTL electrical level, 115 200 bps, 8 data bits, 1 stop bit, no parity.
