- (b) **Frequencies in the 470-512 MHz band.** Within one business day of making a frequency recommendation, each frequency coordinator must notify and provide the information indicated in [paragraph (g)](#g) of this section to all other certified frequency coordinators in the Public Safety Pool and the Industrial/Business Pool.
- (c) **Frequencies in the 769-775/799-805 MHz band.** Within one business day of making a frequency recommendation, each frequency coordinator must notify and provide the information indicated in [paragraph (g)](#g) of this section to all other certified frequency coordinators in the Public Safety Pool.
- (d) **Frequencies in the 1427-1432 MHz band.** Within one business day of making a frequency recommendation, each frequency coordinator must notify and provide the information indicated in [paragraph (g)](#g) of this section to the WMTS frequency coordinator designated in [§ 95.113](/cfr/47/95.113.md) and to all other frequency coordinators who are also certified to coordinate that frequency.
- (e) Each frequency coordinator must also notify all other certified in-pool coordinators on any day that the frequency coordinator does not make any frequency recommendations.
- (f) Notification must be made to all coordinators at approximately the same time and can be made using any method that ensures compliance with the one business day requirement.
- (g) At a minimum the following information must be included in each notification:
  - (1) Name of applicant;
  - (2) Frequency or frequencies recommended;
  - (3) Antenna locations and heights;
  - (4) Effective radiated power (ERP);
  - (5) Type(s) of emissions;
  - (6) Description of the service area; and

- (i) It is the responsibility of each coordinator to insure that its frequency recommendations do not conflict with the frequency recommendations of any other frequency coordinator. Should a conflict arise, the affected coordinators are jointly responsible for taking action to resolve the conflict, up to and including notifying the Commission that an application may have to be returned.
