At the locations specified in paragraph (b)(4) of this section, all operations are secondary to the Wireless Medical Telemetry Service in the 1429-1431.5 MHz band.(3) All operations in the 1429.5-1432 MHz band are primary in status except in the locations specified in paragraph (b)(4) of this section. At the locations specified in paragraph (b)(4) of this section, all operations are primary in status in the 1427-1429 MHz and 1431.5-1432 MHz bands.(4)Locations:(i) Pittsburgh, Pennsylvania-Counties of Westmoreland, Washington, Beaver, Allegheny and Butler;(ii) Washington, DC metropolitan area-Counties of Montgomery, Prince George's and Charles in Maryland; Counties of Arlington, Prince William, Fauquier, Loudon, and Fairfax, and Cities of Alexandria, Falls Church, Fairfax, Manassas and Manassas Park in Virginia; and District of Columbia;(iii) Richmond/Norfolk, Virginia-Counties of Charles City, Chesterfield, Dinwiddie, Goochland, Hanover, Henrico, Isle of Wight, James City, New Kent, Powhatan, Prince George, Southhampton, Surrey, Sussex, and York; Cities of Chesapeake, Colonial Heights, Franklin, Hampton, Hopewell, Newport News, Norfolk, Petersburg, Poquoson, Portsmouth, Richmond, Suffolk, Virginia Beach, and Williamsburg;(iv) Austin/Georgetown, Texas-Counties of Williamson and Travis;(v) Battle Creek, Michigan-County of Calhoun;(vi) Detroit, Michigan-Counties of Oakland, Wayne, Washtenaw, Macomb and Livingston;(vii) Spokane, Washington-Counties of Spokane, WA and Kootenai, ID.(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 |

| 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 |

| Temporary fixed (watts) | 0.611 | 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.(c)Authorized uses.(1) Use of these bands is limited to telemetering purposes.(2) Base stations authorized in these bands shall be used to perform telecommand functions with associated mobile telemetering stations. Base stations may also command actions by the vehicle itself, but will not be authorized solely to perform this function.(3) Except for the transmissions that are permitted under § 90.248(f) of this chapter, airborne use is prohibited.67 FR 41860, June 20, 2002, as amended at 69 FR 39867, July 1, 2004; 72 FR 35196, June 27, 2007; 75 FR 19284, Apr. 14, 2010
