CFR › Title 47 › Chapter I › Subchapter D › Part 90 › Subpart K › Section 90.267 47 CFR 90.267 - Assignment and use of frequencies in the 450-470 MHz band for low power use.
§ 90.267
The following frequencies between 450-470 MHz are designated for low-power use subject to the provisions of this section. For purposes of this section these frequencies are referred to as “low power frequencies.” Pairs are shown but single frequencies are available for simplex operations.
Group A1 Frequencies.
The Industrial/Business Pool frequencies in Group A1 are available on a coordinated basis, pursuant to §§ 90.35(b)(2) and 90.175(b), as follows:
Group A1 frequencies are available for voice and non-voice operations on a co-primary basis. Base, mobile and operational fixed stations will be authorized on Group A1 frequencies. Fixed stations may be licensed as mobile.
Within 80 kilometers (50 miles) of the specified coordinates of the top 100 urban areas listed in § 90.741 of this chapter (“80 km circles”) only low power operation will be authorized. The coordinates of an operational fixed or base station and the geographic center (latitude and longitude) of a mobile area of operation determine whether a station is within an “80 km circle.”
The maximum ERP for low power operation on Group A1 frequencies is as follows:
Operational Fixed or Base
The maximum antenna height for low power fixed stations on Group A1 frequencies will be 23 meters (75 feet) above ground.
Outside the “80 km circles” defined in paragraph (b)(2), full-power operational fixed, base, or mobile stations will be authorized as follows:
Power and antenna height limits are governed by § 90.205 of this chapter;
For any operational fixed, base or mobile station exceeding the low power or antenna height limits listed in paragraph (b)(2), the 21 dBu F(50,10) contour may not overlap any portion of an “80 km circle;” and,
Wide area operations will not be permitted. The area of normal day-to-day operations will be described in the application in terms of maximum distance from a geographic center (latitude and longitude).
