("Ensemble") hereby requests Special Temporary Authorization to operate a DEMS point—to—multipoint field trial test system in Los Angles, California for a limited period of time, to demonstrate and test equipment. Ensemble‘s business primarily consists of developing, manufacturing and providing wireless communications systems and related products $ a n D i e g o and services. Our company employs approximately 60 people in the United States and 20 people abroad and has raised equity capital in excess of $17 million. Ensemble plans to offer a complete system solution to carriers in the LMDS, DEMS and other Broadband Wireless Access (BWA) markets. Our company is currently developing a BWA system for integrated, C oA 9 25 2 2 two—way digital communications that can offer high—speed data, Internet access, advanced telephony services, and video. The technical specifications of the operation are listed below, in accordance with Section 5.56. A FCC Remittance Advice form and a fee payment of $45 are attached. Ph 858 .458 .140 0 1. Applicant name and address Ensemble Communications Inc. 6256 Greenwich Drive, Suite 400 San Diego, California 92122 Attn: Bill Simpson 2. Need for special action Fax 858.458.1401 An STA is requested to allow equipment testing and demonstration in the 24 GHz DEMS band. Ensemble will file an application for an Experimental License in the DEMS band between 24,250 MHz and 25,250 MHz if extended testing is required. www.EnsembleCom.com

& ENSEM B LE Page 2 C O M M U NICATIONS Type of operation Propagation testing and link performance measurements of prototype equipment. Purpose Testing and demonstration of prototype DEMS equipment Time and date February 15, 2000 through August 15, 2000 or the issuance of an Experimental License. Class and nature of service Fixed nodal (hub) and user (remote) stations, experimental Location Specific locations for the hub and remote stations have not been determined at this time. Equipment Ensemble prototype DEMS band point—to—multipoint transceivers. Frequencies Authority to operate on DEMS channel numbers 35 to 39 is requested, Nodal Station 24,250—24,450 MHz and User Station 25,050—25,250 MHz. Ensemble‘s transceivers use TDD, Time Division Duplexing. For this reason we request authorization to transmit and receive Nodal and User station traffic on both sides of the frequency pairs. Ensemble will coordinate with the existing licensee to avoid interference. The frequency stability requirement in section 101.507 will be met. 10. Power The maximum output power of each transmitter will be 30 dBm. The maximum EIRP per channel at the nodal or hub site will be 50 dBm. The maximum EIRP of the user or remote site unit will be 65 dBm.

& ENSEMBLE Page 3 C O M M UNICATIO NS The nodal or hub station will use 60 or 90 degree antennas with a gain of approximately 21dBi. The remote or user stations will use a parabolic antenna with a nominal beamwidth of approximate 3 degrees and a gain of approximately 35 dBi. 11. Type of emission The system operates with multiple carriers where each carrier is 25 MHz wide. QPSK, 16QAM and 64QAM modulation will be used. 12. Height of antenna Antennas will be mounted on building rooftops attached to existing structures. If any new antenna support structures are erected, they will not exceed the height of any existing structures on the rooftops. For additional information regarding this request please contact Bill Simpson, VP Customer Support, at 858—535—2825. Sincerely, Ensemble Communications, Inc. p x¥ Rami Hadar Chief Executive Officer
