RF Fundamentals

How does U-NII-1 operate in relation to the common frequency bands supported by enterprise wireless networks?

  • A It uses a range of higher frequencies and tile enforcement with static power configuration.
  • B It uses a range of lower frequencies with restrictions on transmit power used indoor and outdoor.
  • C It defines subsections with signal handling and is restricted to indoor use helping minimize interference.
  • D It defines class limits for specialty devices and is restricted to outdoor use increasing coverage.
Explanation

In the legacy enterprise WLAN classification, U-NII-1 is the lower 5 GHz sub-band and is limited to indoor operation with constrained power to reduce the risk of interference. The FCC later removed the general indoor-only restriction for 5.15–5.25 GHz operations, so this classification reflects older regulatory and certification-training terminology.
