LoRaTM Target Markets : Ideal for Internet of “Things”

Application Examples Vending machines could alert distributors when a product is sold out or when it requires maintenance Cities could offer smart metering and apps to help drivers find parking spaces Animal lovers could track their pets or study migration patterns over longer distances Logistics providers could track cargo containers on trucks, ships and trains Home heating oil companies could receive automatic alerts when home oil tanks are running low

The LoRaTM Alliance A Strong and Active Ecosystem

Technology Comparison

‘Chirp’ Spread-Spectrum Modulation Innovative & cost sensitive implementation Signal demodulation below the noise floor improves sensitivity by ~20dB Robust against interference, noise, and jamming Multiples signals can occupy the same channel (CDMA) Tolerant to frequency offsets (unlike DSSS)

Supports Private Networks Scalable & Flexible Architecture Options Private Network Individually managed networks, total end-to-end ownership Public Network Telco operator managed networks, servicing subscriber nodes Hybrid Network Enterprise deployment of Nodes & Gateways, for specific area coverage Provisioned to a commercial LoRaWAN server product

LoRa™ Coverage Test

LoRa™ Infrastructure Benefits Star topology with two-way communications Minimizes synchronization overhead, saves power consumption from minimum synchronization and hops in mesh network Not constrained to single application (ie, Zigbee) Easily connect millions of nodes to LoRa concentrators Adaptive data rate feature on Network server Optimizes the network capacity, battery lifetime and creates a fully scalable system Strong ecosystem established with partners Support local area network and nationwide deployment

Getting Started First  Choose the correct LoRa™ Technology: RN2483 Europe: 434MHz and 868MHz; R&TTE Assessed Module RN2903 North America: 915MHz; FCC Certified Module For any other option not available now, please contact Microchip Secondly  Decide what kind of network customer wants to build: Private network: Choose gateway from our partner: Kerlink, Multi-Tech, Link Labs, others coming soon Select current available private network service from service provider partner like Loriot.io, Actility, or Orbiwise. Others coming soon Public network: Customer contacts the available Public Network operator Regionally specific. Many in Europe, (1) in US (Senet). Others coming soon Public Networks have gateway and network server available. Microchip LoRa™ module are able to communicate to those network controller directly when using the standard LoRaWAN Protocol. Finally, test proper Microchip LoRa™ Technology module or LoRa Technology development tool with the chosen gateway/ network option.

FAQs Does LoRa and the LoRa Modules support Point-to-Point Communication? No, P2P is not supported in the LoRaWAN Protocol spec I just bought two Motes, are they able to talk to each other? No, The Motes are pre-loaded with the LoRaWAN protocol and it does not support P2P I just bought two Motes. Now what do I do? Customers will need there own Gateway to set up a LoRa Network or be fortunate enough to be covered by a Public LoRa Network, which means they need to contact the Public LoRa Network Provider I need a couple Motes for my customer, are they available and where can I get them? The LoRa Modules and Motes are released to production. Please order from mD or a local disty The LoRa Modules are not available for samples My customer wants to test the long range capability of the LoRa Technology. How can they do that? Customers need a gateway with a high gain antenna and a high vantage point position to get the maximum (10 mile) range from an end device to the gateway. A LoRa Network needs to be set up to test the range Is LoRa a good replacement for BT, BLE, or Wi-Fi? No, LoRa is a Low-Power Wide Area Network technology. It is not meant to compete with of displace the other PAN/LAN technologies Where can I find more information about LoRa and LoRa Networks? The LoRa-Alliance.org webpage is a great source of information along with the Micorchip.com/lora website Will the LoRa Modules work with the Multi-Tech Gateway? Yes, We have tested and used the Multi-Tech Gateways in many configurations

FAQs (cont’d) Can my customer add their application to the current LoRa Modules? No, the current Modules do not allow customer application code. They do have an ASCII command set that allows you to customize the module Will the LoRaWAN Stack be available for my customer to use? Yes, The MCU08 team is working on releasing the LoRaWAN Protocol Stack in a future MCC release Is there a 32-bit version of the LoRa Module available? The current module is based on a PIC18. A future 32-bit module is in definition. No schedule available How is the LoRa Sub-GHz module different from the MRF89XA or other Sub-GHz solutions? The LoRa transceiver uses a Chirp-Spread Spectrum modulation where the 89XA and other sub-GHz radios are mostly FSK. The CSS provides better receive sensitivity giving it a better range. Is Microchip going to release a LoRa Gateway? No, the gateway in its basic form is a packet forwarder. We are developing an RF module for the Gateway to help customers who want to build their own gateway. This will not be released until FY1Q17
