The RCQ2-868-DK is a high performance wireless modem providing a reliable low cost serial data communications link that can be used for many data communications applications at an exceptionally competitive price. The modem operates in the ISM 868 MHz band. The RF modem is very simple to use and provides a wireless RS232 link with a RF data rate of up to 100 kbps.
Sub-1Ghz technology is becoming one of the chief driving forces behind the Internet of Things (Iot) the main benefits of this technology are:
The low power consumption has always been the predominant feature of the sub 1GHz applications, with new technologies we consumption in sleep mode of less than 1 uA.
The Long Range has become a reality because with new technology you can reach distances of several kilometers in addition, by occupyng the ISM bands in the wireless spectrum belo 1 GHz, this communication avoids the much more crowded band at 2.4 GHZ, where Wi-Fi, Bluetooth, ZigBee and other wireless protocols operate.The RadioControlli transceiver named RC-CC1310-915(CC1310 TI based), this module is ideal for use in IOT applications for the following reasons:
Ultra low power consumption, the consumption of this device is 5.5mA when receiving and 23.5mA when transmitting at +14dBm (13.4mA at +10dBm) in sleep mode the consumption is 0.6µA (microamps).
Long range operations, the sensitivity parameter is -110dBm at data rates of 50 kbps and down to -124dBm when the data rate is 0.625kbps.Interference from other wireless communications can be overcome with 90dB of blocking. The RF output power levels can reach up to +14dBm. All this ensure a robust signaling for long range communications.
