LTN(Low Throughput Network)

  

 

 

 

PHY : UNB

 

UNB stands for Ultra Narrow Band and it is one of LTN radio access technology defined in ETSI GS LTN 003. It is not described in very detail in this spec. For now, following is the only description in terms of PHY described in LTN 003. I will keep updating as find more detailed information.

 

Following is Radio requirement for uplink specified in 5.2.2.1 of LTN 003.
