资源简介：
Cellular phone microwave towers registered with the U.S. Federal Communications Commission. Not all antennas are required to be registered with the FCC, therefore, this data set does not necessarily depict ALL cellular phone communication towers actually present on the landscape. The source data are updated weekly by the FCC as new permits are issued. However, this particular data set is designed for a specific analysis, and is planned to remain static as of the publication date (11/06/2003).
