55	55	When two sensors send uplink in different frequencies, for example, 868.1 nad 868.3. both packets can arrive at the gateway, and the gateway will forward to LoRaWAN Server. Normally, we can consider the gateway support 8 packets per second ( The packets are of different frequencies).

57		-* TX channel frequency is flexible and defined by each downstream from LoRaWAN Server. Please notice when the gateway is in TX mode, RX won't be able to receive packets. So If there are too many downstream in the network. RX capacity will be highly effected.
