Sometimes a service provider’s choice of an air interface can indicate which markets it intends to target. Verizon, for example, is touting its Cat Mi LTE platform for internet of things connectivity. In Europe, narrowband LTE is the preferred mobile IoT platform, where it or Sigfox and LoRa are not seen as the solution.

So one might suggest that Verizon plans to concentrate its IoT efforts in the United States, not international markets. That would be consistent with Verizon’s existing strategy, which is U.S.-centric, compared to AT&T, which already has entered the Mexico mobile market, and many South American video markets.
