AT&T Labs, Inc. January 26,2009 Ms. Nancy Hey Experimental Licensing Branch Office of Engineering and Technology Federal Communications Commission 445 12IhStreet, SW - 7th Floor Washington, DC 20554 RE: Progress Report Number Thirty-three License holder: AT&T Labs, Inc. (formerly SBC Labs, Inc.) Call Sign: KM2XBl Dear Ms. Hey: In accordance with the FCC's Rules and Regulations Part 5, Section 5.204(b), we are hereby reporting on the use of the electromagnetic spectrum under the above experimental license issued to AT&T Labs. Our usage under this license in 2008 has been as follows: 1 ) Transmission in Austin, Texas, to validate propagation and operational characteristics of fixed wireless access systems. These systems were on during most of the year 2008 whenever experimentation and data collection sessions were being conducted (and except during power outages or for equipment maintenance). System 1 : TDD; EIRP 46 dBm Base. 23 dBm CPE. Coordinates: Location Latitude 1 West Longitude - Ground Elevation (feet MSL) Antenna Height (feet AGL) Arboretum 30.390997 97.7521 64 800 120 Jollyville 30.397450 97.750238 800 25

For system 1, a test CPE was also placed inside a van to take measurements and test the operation at a range of up to 3 miles north, and up to 30 degrees to the east and west of the Arboretum base station site. A CPE was also placed at the Jollyville location for the same purposes of taking measurements and testing the system operation. 2) Transmission in Middletown, New Jersey, to evaluate the co-channel interference performance of Ceragon 1500P point-to-point LMDS band microwave radios. This trial was conducted in the Oct 15,2008 to Dec I, 2008 time interval.

During the course of the experiment various EIRP transmit powers up to a maximum of 56.5dBm were used. The paths and transmissions were also co-ordinated with Nextlink Communications as the LMDS license holder in Middletown. NJ. Please direct any inquiries to me at 5 12-372-5818.
