Seeed Studio Modul vysílače s nízkým výkonem a dlouhým dosahem -148 dBm

The Seeed Studio Low Power Long Range Transceiver Module features the LoRa long range modem that provides ultra long range spread spectrum communication and high interference immunity whilst minimizing current consumption. Using Hope RFs patented LoRa modulation technique RFM95969798 can achieve a sensitivity of over -148dBm using a low cost crystal and bill of materials. The high sensitivity combined with the integrated 20 dBm power amplifier yields industry leading link budget making it optimal for any application requiring range or robustness. LoRa also provides significant advantages in both blocking and selectivity over conventional modulation techniques solving the traditional design compromise between range interference immunity and energy consumption.
