Notes:

• All geographic coordinates are now in the NAD-83 standard.
• These results do not include protected frequency records. Valid EMC studies require coordination with protected frequency owners. To obtain a list of protected frequency owners by microwave frequency band and longitude range, go to the Protected Microwave Frequency Information Search.
• Search results include pending frequency assignments. These frequencies will be protected from harmful interference and should be considered part of the spectrum environment. Use the "Frequency Status" field to determine its status, if necessary.
• Data from unsubmitted microwave applications is no longer available in the search results. Search results do include data on new, pending microwave stations that have been submitted and are under study.
• Broadcast stations are assigned temporary account and licence numbers, for administrative use, that may appear in the search results.
• Information on Amateur is not available.
• Detailed information on Spectrum Licences can be found in the Spectrum Licence Browser
• Company codes identified in range 0839xxxxx, 0909xxxxx, 0919xxxxx or 0939xxxxx contain Spectrum Licence information identified by the lower and upper band of the frequency block allocated. Those accounts do not contain site specific data.
• Information on site specific technical information for AWS, PCS or Cellular can be found only from the Geographical Area Search and will appear under company code range 092900000 to 092999999 with temporary licence numbers. This data has been provided by the licensee and has not been verified. The Department assumes no responsibility for errors or omissions in this data.
• Client data in the cellular, PCS and AWS bands should be searched for by specifying the band limit frequencies (Cellular: 869-894/824-849 MHz, PCS: 1930-1995/1850-1915 MHz, AWS: 1670-1675/2110-2155/1710-1755/1910-1915/1990-1995 MHz). Individual channels may not be available.
• Information on non-site specific licences (affiliated mobiles, LMCS, etc.) are not available using a Geographical Area Search. The Frequency Range Search should be used for these type of licences.
• The search can retrieve a maximum of 6,000 records for HTML and XML and 6,500 records for ASCII. If your search criteria would return more than the maximum number of records, an error message will appear and no results will be displayed. If this happens, please narrow your search criteria.
• The fields made available have been chosen to provide comprehensive technical information on two-way radiocommunication systems. For broadcasting stations, fields that are only applicable to radiocommunication stations will be blank. A seprate comprehensive search tool for broadcast stations is planned.
• Information in coded fields can be decoded using the Radio Frequency Search Field Decode Files.
