About FCC Rules
The Rules database contains all of the FCC's wireless-related rules and regulations as they are codified in Title 47 of the Code of Federal Regulations. This database also includes commonly used engineering bulletins issued by the FCC's Office of Engineering and Technology (OET Bulletins). The Rules database is updated whenever changes to the rules become effective. New or revised rules generally do not become effective on the date the FCC releases the order adopting them. Instead, their effective date is usually subsequent to their publication in the Federal Register. The order adopting the rules change specifies when the changes become effective.

Using Connectors
Your search may consist of a group of words or phrases linked by connectors such as and and or  that indicate the relationship between them.

Examples: apple and pear « Both words must be present
  apple or pear « Either word can be present
  apple w/5 pear « Apple must occur within 5 words of pear
  apple not w/5 pear « Apple must not occur within 5 words of pear
  apple and not pear « Only apple must be present


If you use more than one connector, you should use parentheses to indicate precisely what you want to search for. For example, apple and pear or orange juice could mean (apple and pear) or orange, or it could mean apple and (pear or orange).

Noise words, such as if and the, are ignored in searches. » More about connectors   

Using Wildcards ( * and ?)
A search word can contain the wildcard characters * and ?. A ? in a word matches any single character, and a * matches any number of characters. The wildcard characters can be in any position in a word.

Examples: appl* « would match apple, application, etc.
  *cipl* « would match principle, participle, etc.
  appl? « would match apply and apple but not apples.
  apple not w/5 pear « Apple must not occur within 5 words of pear
  ap*ed « would match applied, approved, etc


Note that use of the * wildcard character near the beginning of a word may slow search performance.


Using Stemming
You may use the ~ character to extend or stem your search to cover grammatical variations on a word.

Examples: test~ « would also find testing
  apply~ « would also find applying, applies, and apply
