Add to Watch List

The SX127x family with LoRa™ provides significant benefits for range, robust performance, and battery lifetime compared to competing technologies.

When combined with the LoRa™ concentrator from Semtech, superior system performance can be achieved by extending the range, increasing the capacity of the network, improving battery lifetime, and robustness to interference. The LoRa concentrator is a multi-channel, multi-modem solution that can simultaneous receive multiple packets. The simultaneous reception of multiple packets on the same channel is permitted by the advanced properties of the LoRa modulation. Semtech’s LoRa solution is leading to drastic improvements in performance, range, battery lifetime, and network capacity compared to existing technologies.
