Which similar 3GPP technologies exist for IoT?

  • 3GPP-standardized technologies for IoT include:

    • CAT1: Low-end LTE device class (for larger data volumes)
    • LTE-M/CAT-M1: Driven primarily by US market & Orange and a replacement for 2G in US; potential use cases require less data transfer than LTE or CAT1.
    • NB-IoT: driven primarily by European and Chinese market; only for very small data volume and has the best indoor coverage compared to CAT1 and CAT-M
    • EC-GSM: extension for GPRS; not widely adopted
