Main applications of wireless transceivers: Remote wireless meter reading, home and building automation, wireless alarm and security systems, industrial monitoring, remote irrigation systems
Product introduction: The RFM95 transceiver belongs to the LoRaTM remote communication module, which provides ultra-long-distance spread spectrum communication and has superior anti-interference and ultra-low current consumption. RFM95 uses Maple`s patented radio frequency LoRaTM module modulation technology, the receiving sensitivity is above -148dBm, and the cost of crystal and materials is low. The combination of high sensitivity and integrated +20dBm power amplifier reduces the link budget and leads the industry, making it an ideal choice for long-distance and stable performance applications. LoRaTM has strong advantages in the field of traditional modulation technology and in terms of modularity and sensitivity, which can solve traditional design problems in long-distance, anti-interference and energy consumption. RFM95 has high-performance (G)FSK modulation mode, supports WMBus, IEEE802.15.4g and other systems, RFM95 transmits low phase noise, high sensitivity, high-quality receiving link and IIP3, and the current consumption is significantly lower than the same device in the industry .
