Author: Radio Group Date: February 11th, 2014 Revision: November 30th, 2021 Subject: Integration Guide – Mizar Radio Module 915 MHz Introduction Mizar radiofrequency (RF) module operates in the 902-928 MHz ISM frequency band.
Author: Radio Group Date: February 11th, 2014 Revision: November 30th, 2021 Subject: Integration Guide – Mizar Radio Module 915 MHz Operational description The equipment is a radio module to be integrated inside cordless devices. It is based upon an FSK ( Frequency Shift Keying Modulation ) Half-Duplex transceiver working in the ISM band from 902 to 928 MHz. The radio module has a UART interface to exchange data and commands.
Author: Radio Group Date: February 11th, 2014 Revision: November 30th, 2021 Subject: Integration Guide – Mizar Radio Module 915 MHz Radio module operates in CSMA-CA (carrier sense multiple access – collision avoidance) : transmission is enabled when the RF channel is not busy by the use of a “carrier detect” function. Radio module accesses the channel in a fair way using a backoff algorithm.
