(collectively "Teligent"), hereby request Special Temporary Authority ("STA") for a period of six months to test non—type accepted equipment currently used in the LMDS (28 GHz frequency band) to validate radio vendor‘s performance claims and access the suitability of such equipment to 24 GHz operations. As part of its ongoing efforts to test and operate non type—accepted equipment in the 24 GHz Digital Electronic Message Service ("DEMS") band‘, Teligent is working with various radio equipment vendors to secure a reliable and efficient platform for its 24 GHz operations. The equipment Teligent seeks to test is currently being tested in the 28 GHz band by the product manufacturer. The tests to be conducted would allow Teligent to assess the performance of the vendor‘s equipment and the equipment‘s interoperability and suitability for retrofitting to 24 GHz operations compatible with Teligent‘s planned network. Grant of this STA serves the public interest by facilitating the continued development of radio technique, equipment, operational data, and engineering data related to DEMS. 1 Teligent currently holds two experimental STAs to test and operate non type—accepted equipment in the 24 GHz band, Call Sign KS2XAT, File No. 0060—EX—ST—1998 and Call Sign WAIXFS, File No. 0152—EX—ST—1999.
