Is there a difference between Lora and LoRaWAN?

Yes, Lora is a modulation technique using chirp spread spectrum whereas LoRaWAN is a network topology define by the Lora Alliance. While all LoRaWAN uses LoRa, not all LoRa is LoRaWAN.

A LoRaWAN system is comprised of end devices, gateways and network servers and a broadcast from a LoRaWAN end device must be forwarded by a LoRaWAN gateway to a LoRaWAN network server for authentication.

But it is possible to have point to point LoRa devices that use a proprietary protocol that are not interoperable with LoRaWAN.

Laird RS186 and RS191 are LoRaWAN end devices and can only send data through a LoRaWAN gateway to a LoRaWAN network server.
