Questions and answers

What is spectrum certification?

Spectrum certification is the statutory process whereby national regulatory bodies, NTIA and Federal Communications Commission review telecommunications systems for compliance with national spectrum standards and determine electromagnetic compatibility. (paragraph 2)

When must locally purchased spectrum-dependent systems be reviewed?

Local purchases of spectrum-dependent systems will be reviewed by the installation spectrum manager to evaluate spectrum supportability prior to the obligation of funds.

What information should be included in a ServiceNow request for a spectrum-dependent system?

When a ServiceNow request is submitted, include as much information as possible about any spectrum-dependent component (e.g., Federal Communications Commission (FCC) ID number, manufacturer, make, model number, frequency range, power level, etc.).

How are out-of-band requirements handled?

The NTIA, Spectrum Planning Subcommittee, may approve out-of-band requirements with an analysis and justification.

What is required for out-of-band operations?

Out-of-band operations are operated on a strict non-interference basis.
