عملکرد LORA1276-868MHZ
Description:
LoRa1276 Wireless
Transceiver Module adopts Semtech RF transceiver chip SX1276 which
LOS transmission distance can reach to Long Distance.
The
SX1276/77/78/79 transceivers feature the LoRa® long range modem that
provides ultra-long range spread spectrum communication and high
interference immunity whilst minimizing current consumption.
Using Semtech’s patented LoRa modulation technique SX1276/77/78/79 can achieve a sensitivity of over -139dBm
using a low cost crystal and bill of materials. The high sensitivity
combined with the integrated +20dBm 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.
