To Whom It May Concern:
As a Manager of Radio Frequency (RF) Engineering at AT&T Mobility, I attest to the following
with regards to the proposed wireless communications site located at 75 Prospector Road, in
the City of Aspen:
1. The proposed AT&T wireless telecommunication facility will comply with all current
Federal communications Commission’s (FCC) guidelines and specifically OET Bulletin
65 for cumulative measurements of radio frequency power densities and
electromagnetic fields.
2. The proposed AT&T wireless telecommunication facility will comply at all times with current
FCC regulations prohibiting localized interference with reception of television and radio
broadcasts.
3. The proposed AT&T wireless telecommunication facility will not interfere with any public safety
frequencies servicing the city and its residents. Specifically, said facility will not interfere with
any municipal radio or wireless data communications equipment that is operating in the 800
Hz frequency band. All AT&T base station radios meet or exceed FCC regulations.
4. Immediately upon notification by the Aspen Police Department or any other bona fide Public
Safety entity of interference with any public safety radio or wireless data communication
equipment, AT&T shall cease operation at the above described site until such time as a fix or
solution has been implemented so that operations can resume without interference.
5. The proposed AT&T site will be operating at the following FCC licensed frequencies.
Transmit: 869-880MHz and 890-891.5MHz, 1930-1950MHz, 1975-1980MHz, 734-740MHz
and 716-722MHz, 788-798MHz, 2130-2145MHz, 2160-2170MHz , 2350-2360MHz, 2315-
2320Mhz, 2345-2350Mhz.
Receive: 824-835MHz and 845-846.5MHz, 1850-1870MHz, 1895-1900MHz, 704-710MHz,
758-768MHz, 1730- 1745MHz, 1760-1770Mhz, 2305-2315MHz
6. The AT&T network will operate at an average output not exceeding Approx 500W Max
Comp. (Urban)/1000W (rural) ERP for UMTS and 1640W/MHz EiRP (urban)/3280W/MHz
EiRP (rural) for LTE per FCC transmit power limits in the CMRS Bands.
Further, AT&T agrees to comply with the zoning ordinance in regard to notification and monitoring
procedures to ensure that no interference issues exist with local emergency equipment.
Sincerely,
David Black
