Description
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 RFM95W 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, RFM95W 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 .
