main content

Cellular IoT deployments rely on a mix of low- and mid-band LTE spectrum to balance coverage, penetration, power efficiency, and device cost. LTE Cat-1bis, LTE-M, and NB-IoT operate across FDD and TDD bands defined in 3GPP 36.101, with band support varying by carrier, region, and device category.

  • Filter by duplex mode (FDD or TDD), frequency range, or region to identify supported Cellular IoT bands
  • Reference carrier band listings to confirm network compatibility for Cat-1bis, LTE-M, or NB-IoT devices
  • Use Popular Antenna links to access RFWEL-curated antenna groupings aligned to specific LTE bands

  • Category NB systems operate in HD-FDD (Half-Duplex Frequency Division Duplex) duplex mode (UE device transmits in one frequency band and receives in another frequency band, but it cannot transmit and receive simultaneously).
  • The difference between LTE-Cat1 and LTE.Cat1.bis is that LTE-CAT1 BIS operates using a single antenna while offering the same level of data rate, reliability, and latency. LTE Cat1, requires an IoT device to have 2 antennas. LTE Cat1 BIS IoT devices are therefore smaller and more cost effective.
