Lora and similar

Lora

  • China LoRa Application Alliance (CLAA) recommended 470 ~ 510MHz. The main frequency ranges in other areas are as follows:
  • Europe 863 to 870
  • North America 902 to 928

NB-IoT

  • the world's mainstream band is 800MHz and 900MHz. China Telecom will use 800MHz as the preferred band for deploying NB-IoT.
  • China Unicom will choose 900MHz to deploy NB-IoT
  • China Mobile may re-build the existing 900MHz band.
  • The main frequency of NB-IoT on a global scale is shown in the following table:

Sigfox

  • Europe, Middle East: 868MHz (ETSI 300220) 863 to 870
  • North America: 902MHz (FCC part 15) 902 to 928
  • South America / Australia / New Zealand: 920MHz (ANATEL 506, AS / NZS 4268).

Weightless

  • as an open standard LPWAN wireless technology, it works throughout the entire license-free Sub-GHz ISM / SRD band, which can be deployed globally: 169/433/470/780/868/915/923MHz.
