WebDec 9, 2024 · If they use the LoRaWAN public network sync preamble and the 2nd US 915 uplink band, then a TTN gateway would receive almost all in-range packets and report them up the backhaul. But if they use the private preamble sync word (or some other sufficiently distinct pattern), the majority of the packets will never trigger the gateway’s “might be a … WebSchmidl and Cox propose a synchronization algorithm that bases on an OFDM symbol that has a special structure. In particular, the special symbol, denoted as the preamble, consists of two repeated parts, prepended by a cyclic prefix (CP). As such, in this notebook, we will employ the following overall frame structure:
