How IoT communicate with the internet is a key aspect when conceiving of a connected project. There are a number of ways to connect your sensors to the internet dependent upon the needs and limitations of a particular project. Key aspects when considering network connectivity: Range - are you deploying to a single office floor or an entire city? Data Rate - how much bandwidth do you require? How often does your data change? Power - is your sensor running on mains or battery? Frequency - have you considered channel blocking and signal interference? Security - will your sensors be supporting mission critical applications?

LRM001 with RN2483 can support P2P ,though Microchip are not promoting or supporting P2P. The RN2xx3 family of products are designed to support the LoRaWAN. The LoRaWAN architecture dictates a hierarchical structure of gateways and network/application servers and has no concept of P2P communication.   A good analogy is walkie-talkies versus cell phones. Walkie-talkies have their uses, they are simple and can be very low cost, they serve a purpose. http://www.microchip.com/forums/m925420.aspx#925420

LiYa tech, a leading provider of LoRa RF, has announced that its LRM001 with RN2483 LoRa® from Microchip which is the world's first to pass the LoRa Alliance's LoRaWAN™ Certification Program. The RN2483 module was independently tested by Espotel's accredited test laboratory to meet the functional requirements of the latest LoRaWAN 1.0 protocol specification, for operation in the 433 MHz and 868 MHz license-free band. This ensures that designers can quickly and easily integrate their end devices into any LoRaWAN network. The LoRaWAN standard enables low-data-rate Internet of Things (IoT) and Machine-to-Machine (M2M) wireless communication with a range of up to 10 kilo meter hundreds of wireless sensor nodes to LoRaWAN gateways.
