+        Configure the default link check interval (in seconds). 0 means the link
+        check process is disabled. The link check process is used by an
+        end-device to validate its connectivity with the network. The frame has
+        no payload. When a `LinkCheckReq` is received by the network server via
+        one or multiple gateways, it responds with a `LinkCheckAns` MAC command.
+
+config LORAMAC_DEFAULT_RX1_DELAY
+    int "RX1 window delay (in milliseconds)" if LORAMAC_ADVANCED_OPTIONS
+    depends on USEMODULE_GNRC_LORAWAN || USEMODULE_RN2XX3
+    default 1000

Please correct me if I am wrong, isn't the time calculated based on the time for the uplink to reach the gateway + network latency. The time for uplink to reach the gateway is what I meant by time on air.  I used this tool < https://avbentem.github.io/airtime-calculator/ttn/eu868/52,12 > to calculate the TOA, assuming an overhead size of 15 bytes in each packet.
