Sec. 90.769  Construction and implementation of nationwide licenses.

    (a) A nationwide licensee must construct a sufficient number of base 
stations (i.e., base stations for land mobile and/or paging operations) 
to provide coverage to:
    (1) A composite area of at least 750,000 square kilometers or 37.5 
percent of the United States population within five years of the 
issuance of its initial license; and
    (2) A composite area of at least 1,500,000 square kilometers or 75 
percent of the United States population within ten years of the issuance 
of its initial license.
    (b) Nationwide licensees offering fixed services as part of their 
system may meet the construction requirements of paragraph (a) of this 
section by demonstrating an appropriate level of substantial service at 
their five- and ten-year benchmarks.
    (c) Licensees must submit maps or other supporting documents to 
demonstrate compliance with the construction requirements of paragraphs 
(a) and (b) of this section.
    (d) Failure by a nationwide licensee to meet the construction 
requirements of paragraphs (a) or (b) of this section, as applicable, 
will result in automatic cancellation of its entire nationwide license. 
In such instances, nationwide licenses will not be converted to 
individual, site-by-site authorizations for already constructed 
stations.
    (e) Nationwide licensees will not be required to construct and place 
in operation, or commence service on, all of their authorized channels 
at all of their base stations or fixed stations.
