Learn your connectivity options for IoT



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


  1. Excellent Sensitivity = Range

  2. Mature Ecosystem 



  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


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


  1. Projected World Wide Coverage 




  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 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)

Licensed Frequencies


*NOTE Weightless can also operate in 

licensed sub-GHz frequencies 

  • Subscription model $/device/

  • Higher Power Consumption  (3-4X more than Weightless) 

  • Data must go through operator

  • CANNOT be used to private networks

Unlicensed Frequencies

(ISM Bands)

Weightless or LoRaWAN

  • Firmware-Over-The-Air

  • Very Spectrum Efficient (12.5Khz/channel)

  • Bidirectional Communication

  • Synchronous network - Highly Scalable 

  • Open Standard

  • Robust FEC Convolutional Coding


  • No Standard Firmware-Over-The-Air [1]                    

  • Poor Spectrum Efficiency (125 Khz/channel)

  • Limited Downlink

  • NOT synchronous = prone to collisions [2]

  • NOT an Open Standard - Single RF IC Vendor

  • Basic Hamming Coding

[1]technically possible using class C for very small # of devices but NOT standardized or scalable; class C is VERY power draining and not suitable for battery powered devices

[2] Class B is synchronous but has 128-256 sec latency and requires special hardware - end devices must have crystal (hardware availability?)
