Due to the need to prevent potential harmful interference to XM‘s operations, XM requests that the Office of Engineering and Technology ("OET‘) require Alcatel—Lucent to adhere to existing Part 27 limits for these experimental operations. XM is the licensee of a Satellite Digital Audio Radio System in the 2332.5—2345 MHz band that provides over 170 channels of high—quality, continuous, multi—channel audio service throughout the United States. Over 7.7 million customers currently subscribe to XM‘s service. XM urges OET to require any equipment operated in the 2.3 GHz band pursuant to this STA to satisfy the out—of—band emission limits and other technical requirements for operations in the 2.3 GHz Wireless Communications Service band, as specified in Part 27 of the Commission‘s rules. Compliance with these technical restrictions is critical to avoiding harmful interference to XM‘s subscribers. ce nE WASHiNGTON DC 20002—2164 PH 202 380 4000 FAX 292 380 4500 ._cron P WWeXvp \BOQ Ec«wno AD/Q COM
