(5) All operations in the 1429.5-1432 MHz band authorized prior to April 12, 2002 are on a secondary basis.

(6) For secondary operations only fixed stations are permitted. At the locations specified in (b)(4) of this section, secondary operations are performed in the 1429-1431.5 MHz band. For all other locations, secondary operations are performed in the 1427-1429.5 MHz band. The maximum power is 1 watt EIRP.

(7) For primary operations base, mobile, operational fixed and temporary fixed operations are permitted.

(i) At the locations specified in paragraph (b)(4) of this section, primary operations are performed in the 1427-1429 MHz and 1431.5-1432 MHz bands. The maximum ERP limitations are as follows:

Operation	Frequency range (MHz)
	1427-1428	1428-1428.5	1428.5-1429	1431.5-1432
Fixed (watts)	61.1	6.11	0.611	0.611
Mobile (watts)	0.611	0.611	0.015	0.015
Temporary fixed (watts)	0.611	0.611	0.611	0.611

(ii) For all other locations, primary operations are performed in the 1429.5-1432 MHz band. The maximum ERP limitations are as follows:

Operation	Frequency range (MHz)
	1429.5-1430	1430-1430.5	1430.5-1431.5	1431.5-1432
Fixed (watts)	0.611	0.611	6.11	61.1
Mobile (watts)	0.015	0.611	0.611	0.611

(8) Wide area operations will not be authorized. The area of normal day-to-day operations will be described in the application in terms of maximum distance from a geographical center (latitude and longitude).

(9) Assignable frequencies occur in increments of 12.5 kHz from 1427.00625 MHz to 1431.99375 MHz.

(10) Licensees, however, may combine contiguous channels up to 50 kHz, and more than 50 kHz only upon a showing of adequate justification.

(11) For any operation in the 1427-1432 MHz band, the predicted or measured field strength - in the WMTS primary band - at the location of any registered WMTS healthcare facility shall not exceed 150 uV/m. For the locations specified in (b)(4) of this section, WMTS is primary in the 1429-1431.5 MHz band. For all other locations, WMTS is primary in the 1427-1429.5 MHz band.
