Frequency Details

Enter detailed information for the mobile station frequency.

Fields

Application Type

Indicates if the current record represents new information or modifications to Industry Canada's information about your existing systems. (Note that you cannot update this selection once you save the record.) When you first create the record, select Create New to specify information about a new frequency. For frequencies on a modified mobile station, select Search and Modify to change information related to an existing frequency. Each time you select Search and Modify, the Authorized Frequencies for the Modified Station page appears in a new window so that you retrieve information about your authorized frequencies.

Record ID.

Unique number assigned to each individual frequency record at the time of the original data entry in our database. Applies to modified frequencies only (blank for new frequencies).

Last Edited

Date generated by the system when the associated record was most recently saved.

Channel

The letter that was assigned to your channel when it was created, e.g., "A". (For a duplex channel, a read-only copy of the main channel with the Tx and Rx values reversed is created by the system, and identified with an asterisk, e.g., "A*".) The channel determines the frequencies to be used, and whether there is a Tx and Rx component. Use the Select link to open the Channel List page in a new window, where you can select an existing channel from your channel plan, or create a new channel.

Tx/Rx

Type of channel. This value is set when you select a channel, and determines which fields can be edited on this form.

Stations with which communication is desired

Identify the fixed or mobile stations or repeater that the station will be communicating with. Include the type of station. For fixed stations or a repeater station, include the call sign if known.

Tx Model Number

Model number of the Tx radio equipment. Use the Select link to find and retrieve radio information from the Radio Equipment List (REL). A search form opens in a new window. (Confirm that the information retrieved is correct before you save this record.) Not available for Rx Only frequencies, otherwise mandatory for new frequencies.

Rx Model Number

Model number of the Rx radio equipment. Use the Select link to find and retrieve radio information from the Radio Equipment List (REL). A search form opens in a new window. (Confirm that the information retrieved is correct before you save this record.) Not available for Tx Only frequencies, otherwise mandatory for new frequencies.

Tx Manufacturer

Name of the radio equipment manufacturer.

Rx Manufacturer

Name of the radio equipment manufacturer.

Tx Certification Number

Industry Canada approval number for the transmission radio equipment.

Rx Certification Number

Industry Canada approval number for the reception radio equipment.

RF Output Power (W)

Power of the mobile stations on this frequency, in Watts. Must be between 0.0001 and 999.0000.

First Bandwidth (kHz)

Necessary bandwidth of the first emission (in kHz). This data item is coupled with the First Class of Emission. For Rx Only frequencies, represents the reception bandwidth. For all other records, represents the transmission bandwidth. Must be between 0.01 and 9999.00.

Second Bandwidth (kHz)

Necessary bandwidth of the second emission (in kHz). This data item is coupled with the Second Class of Emission. For Rx Only frequencies, represents the reception bandwidth. For all other records, represents the transmission bandwidth. Must be between 0.01 and 9999.00.

First Class of Emission

ITU designation for the first class of emission. For Rx Only frequencies, represents the reception class of emission. For all other records, represents the transmission class of emission. Must be a valid class of emission code at least three characters long.

Second Class of Emission

ITU designation for the second class of emission. For Rx Only frequencies, represents the reception class of emission. For all other records, represents the transmission class of emission. Default values derived from REL Must be a valid class of emission code at least three characters long.

Is this station part of a mobile-to-mobile system?

Indicates if this frequency is used to communicate exclusively with other mobile stations. If a station has mobile-to-mobile frequencies, you should describe the area where the frequency is used (below), and define the station's radius of operation (on the mobile station page).

Please describe the geographic area...

For mobile-to-mobile frequencies, a description of the areas where the frequency is used. (On the mobile station page, you should also define the radius of operation for any station with mobile-to-mobile frequencies.) Initially set to "modification" for modified frequencies. There are a number of ways to define the area:

• a list of municipalities
• the highways or roads along which you travel
• relative to geographical features
• entire provinces
