 # MQTT-SN Transparent / Aggrigating Gateway
 
 **MQTT-SN** requires a MQTT-SN Gateway which acts as a protocol converter to convert **MQTT-SN messages to MQTT messages**. MQTT-SN client over SensorNetwork can not communicate directly with MQTT broker(TCP/IP).   
-This Gateway can run as a transparent or aggrigating Gateway by specifying the gateway.conf.
