IoT Segments Trade-offs
IoT: Private vs Public Network
Private Network – Individual Managed NetworkMetering, Security, Home Automation, Industrial Control
Public Network – Telecom/Operator Managed NetworksSmart City, BMKG, Crisis Center, Public Parking, etc
So, What is LoRa ?“LoRa stands for Long Range Radio. It is the wireless technology mainly targetted for M2M and IoT networks “
-quoted from http://www.rfwireless-world.com/
History of LoRaThe technology behind LoRa™ was developed by Cycleo, a French company acquired by Semtech in 2012. LoRa™ is proprietary, but it appears to use some sort of "simpler" CSS (Chirp Spread Spectrum) pulsed FM "sweeping frequency" modulation rather than DSSS (Direct Sequence SS) or FHSS (Frequency Hopping SS).
Range 2-5 Km in dense urban and 15 Km in suburban areas
Frequency band ISM band 868 MHz and 915 MHz
Standard IEEE 802.15.4g
Modulation spread spectrum modulation type is used which uses wide-band linear FM pulses. The frequency increase or frequency decrease over certain period is used to encode data information to be transmitted. It gives 30dB improvement over FSK.
Capacity One LoRa gateway takes care of thousands of nodes.
Battery Longer battery life
LoRa Physical layer Takes care of frequency, power, modulation, signaling between nodes and gateway
Others Support variable data rates, multi-channel simultaneously, support mobile and fixed nodes
LoRa Spec
LoRaWANLoRaWAN™ is a Low Power Wide Area Network (LPWAN) specification intended for wireless battery operated Things in regional, national or global network.

Ubiquitous network coverage
CONSIDERATIONS • Friction for 3rd party devices joining WiFinetworks
• Provisioning of credentials s difficult
• Very short range • Requires key coordination
at both endpoint and access Point
• Needs access point (phone or application specific device)
• Low data throughput • Networks do not exist everywhere• Quality of Service not guaranteed in
unlicensed spectrum.• Current provisioning and key
management schemes make large scale manufacturing difficult.
• Short range • Link performance problems • Deployment difficult • Interoperability is often not
possible due to configuration differences and key management
• Recurring cost• Expensive
chipsets • Short battery life • Expensive
