LoRaWAN

LoRaWAN is a LPWAN protocol specification built on top of the LoRa technology developed by the LoRa Alliance. The hardware uses proprietary, chirp spread spectrum (CSS) radio modulation technology enabled by a RF IC of a single vendor - Semtech. There are currently 3 classes of LoRaWAN: A, B, and C. The majority of all end devices we see today are class A which does not support firmware-over-the-air.

Good For: Smaller sized networks or end devices with less frequent uplink requirements

PROS: 

  1. Excellent Sensitivity = Range

  2. Mature Ecosystem 

 

CONS: 

  1. HEAVY Spectrum Usage: 125Khz / channel 

  2. Class A/C uncoordinated transmissions 

  3. Class B requires end device module crystal 

  4. Class B has 128-256 second latency

  5. No FOTA (firmware-over-the-air) method for large networks

NB-IoT

Narrowband IoT (NB-IoT) is a LPWAN radio technology standard developed to be connected using licensed cellular telecommunications bands to be operated by telecom companies 

Good For: Public Network Applications especially logistics, city-to-city, outdoor tracking applications, & consumer products

PROS: 

  1. Projected World Wide Coverage 

 

 

CONS: 

  1. Higher power consumption (over 4X more than Weightless)

  2. No Private Networks (Public Only - Must Work with Telecom)

  3. Recurring Subscription Fees ($/device)

Weightless

Weightless is a narrowband LPWAN part of a truly open standard developed by the Weightless SIG. Weightless was designed to be the most reliable connectivity option for IoT end devices.  

Good For: Private Industrial, Building, Office, City Networks with high uplink and/or high downlink requirements. 

Why companies choose Weightless?

  1. Private/Public Network Flexibility 

  2. Firmware-Over-The-Air

  3. HIGH Reliability requirements

  4. Large Scale Network with frequent uplink transmissions

  5. Downlink oriented applications

  6. Lower latency requirements 4-8 secs

  7. Higher Data Rate 

  8. Narrowband 100kHz (8 x 12.5kHz sub-channels)
