Exhibit 1: " Particulars of Operation" GeoPhone‘s VSAT terminals use a new type of spread spectrum modulation which is not accommodated by the normal emission and modulation designators listed in Section 2.201 of the FCC Rules. This attachment explains the new emission and modulation types used for transmission of low rate digital data, compressed digital voice data, or facsimile data between GeoPhone Terminals. The VSAT terminals use GeoPhone‘s new multiple access technology called CAMA ( Patent # 5557637 ). CAMA is a type of code assigned multiple access transmission system which maps a unique fixed spread spectrum code for each terminal into a fast frequency hopped spread spectrum waveform that is transmitted in a nominal 1.3MHz bandwidth sub—band of a standard commercial Geostationary Ku or C—Band Satellite transponder. Each terminal in the GeoPhone network has a unique 16 digit code which assigns a sequence of sixteen frequencies (sixteen "chips") in a unique order of transmission within a selected transponder sub—band. This 16—chip sequence is used on each transmitted symbol, therefore it is a "very fast" frequency—hopping signal. The signal as transmitted is a spread spectrum signal having uniform power spectral density over the selected subband and having very well behaved spectral characteristics. Digital techniques are used to generate the waveforms that are transmitted by each terminal. The design provides that generation of the waveforms is done in such a way so to insure that each frequency chip starts and stops at peak voltage so that hopping rate artifacts do not appear in the transmitted spectrum. Partially orthogonal codes are used so that multiple users can operate in the same subband simultaneously. Data Transferred: Compressed Digital Voice at 5.33 kbps Standard Commercial Facsimile at 4.8 kbps Digital Data at 4.8 kbps from/to customer equipment Standard Computer Modems at 4.8 kbps 800 bps terminal to terminal overhead channel Maxinuum Data Transfer Rate per channel; The 7.2 kbps data rate per channel is the same for all data types but is processed differently for Voice or for Data / Fax to provide additional Forward Error Correction gain and BER performance for both Data and Fax. (27, 21) Reed—Solomon Forward Error Correction is applied to the combined 4.8 Kbps data/fax and 800 bps ~ overhead channel (for packet framing, frequency/power control) for a total rate of 7.2 kbps per data/fax channel. (27, 23) Reed—Solomon Forward Error Correction is applied to the combined 5.33 Kbps voice and 800 bps overhead channel (for packet framing, frequency/power control) for a total rate of 7.2 kbps per voice channel. Maximum Data Transfer Rate per Terminal: The data from each channel is buffered into the transmitter at 7.2 kbps to accommodate up to four time division multiplexed channels which can be provided simultaneously from each terminal. The maximum transmit rate for the terminal would be four times the maximum channel data transfer rate of 7.2 kbps, or 28,800 bits per second. Modulation Characteristics (Complex): The system uses 8 — Bit modulation such that the symbol rate = 28,800/8 = 3,600 Symbols per second for all four channels or 900 Symbols per second per channel. Modulation is imparted onto the spread spectrum frequency hopped transmitted signal by adjusting the timing of the chips in the assigned sequence. By varying the leading chip in the transmitted sequence, a symbol having 8 bits is transmitted during each set of 16 chips transmitted between two terminals. In this way, no other modulation type, such as FSK or PSK is required to be added to the fast frequency hopped carrier. Euei,ts ?f/ ‘be /litu1 4

Exhibit 2: Statement of Proposed Experiment INTRODUCTION GeoPhone Company, L.L.C. is developing a new type of low cost Very Small Aperture Terminal (VSAT) for use with existing and planned Geo—Stationary Satellites to provide low data rate voice, fax and data services for rural customers not currently served by public telephone infrastructure. Much of GeoPhone‘s projected markets are in developing countries, but certain private low rate data network applications that are available in the U.S. domestic market can also be served by this product. GeoPhone is developing this new VSAT terminal to provide services comparable to wired telephone infrastructure but at a very low competitive cost of $1,500.00 to $ 2,000.00 per telephone line. STATEMENT OF THE PROPOSED EXPERIMENTS GeoPhone Company, L.L.C. is requesting an experimental license to operate two (2) of its C—Band prototype GeoPhone VSAT terminals at GeoPhone facilities at N 38:59:37 , W 076:32:47 in Annapolis, Maryland. This site is fully coordinated (see attached Exhibit 4, Frequency Coordination Report). These terminals will be production prototypes of the GeoPhone VSAT terminal at C Band, manufactured by GeoPhone for use in communications of low data rate voice, facsimile and computer data at 5333 bps and 4,800 bits per second between the two GeoPhone terminals in a full mesh configuration. Each terminal will have four (4) telephony RJ—11 input ports capable of interface to a standard telephone handset, standard facsimile machines, selected two wire PABX or standard personal computer data modems. More extensive Ku band tests have been conducted since April 1997 using the first of twelve planned terminals in GeoPhone‘s Experimental Ku Band network (WAZXBI1). These tests have provided initial validation of the new signaling concept, modem performance, frequency and power control validation, RF hardware and initial network operation. Testing with this Ku—Band experimental network is continuing. The current request for a C—Band license is required to complete development of GeoPhone‘s companion C—Band product line. Experimentation will be less extensive than for the Ku band network and will consist primarily of validating repeatability of system, software, and hardware performance results obtained at Ku band. Various over the air experiments will test voice, fax, and personal computer data transmission and the combination of all three types of transmissions simultaneously at C Band. Frequency and power calibration and control performance will also be verified. All transmissions will originate from and be received in the United States of America, all transmissions will be over existing, domestic, commercial satellites ( Hughes Galaxy and GE Americom) and there will be no services provided to the general public as part of these experiments. SPECIFIC OBJECTIVES OF THE EXPERIMENTS The specific objectives of these experiments will be to verify and validate through careful measurement the following items: 1. The technical parameters of individual components, terminals, network, and terminal to terminal setup protocol‘s under realistic operating conditions using a Domestic, Commercial C Band Geo—Stationary Satellite. 2. The behavior of the network during extremes of weather and temperature.

3. The operation of active uplink power control systems including both Hardware and Software components 4. Network behavior with typical video and/or communications traffic on adjacent cross—polarized transponders at the same frequency or on adjacent co—polarized transponders of different frequency. i 5. The achievable bit error rates, voice quality and data transfer quality for practical applications of the terminals in their intended markets. 6. The ability of the distributed network management software to detect and isolate remote terminal faults, and to reliably shut down terminals which are not within designated operational boundaries. 7. Behavior and operations of the distributed network management software system, the billing software system, the call handshake and terminal link management software system, and the administrative terminal automatic terminal diagnostic software management system. CONTRIBUTION OF THE EXPERIMENT TO THE DEVELOPMENT RADIO The GeoPhone terminals represent an entirely new type of radio communications system using typical geostationary communications satellites. In order to meet the increasing needs of rural markets for telephony, facsimile and low rate data services, particularly in developing countries or in economically depressed regions, GeoPhone uses new technologies that optimize the number of simultaneous conversations per transponder subband and allow for very low cost operations from multiple fixed locations. The experiments proposed by GeoPhone will validate and optimize the design of this new VSAT technology and will demonstrate the new and advanced features of system operations including: e Use of advanced CAMA ( Convolution Ambiguity Multiple Access) technology —— a type of CDMA technique that is asynchronous and has very high spectrum reuse capabilities. e Development of an affordable very well behaved fast frequency hopping spread spectrum transmitter and receiver that is low enough in cost for use in rural telephony applications, thereby providing unique transpomder frequency spectrum reuse capabilities. e Use of a "hub—less" distributed network management system * Use of advanced monolithic transmitter and receiver components e Use of a completely software programmable transmitter and receiver system that can be reconfigured over the air through network wide broadcasts e Deployment of a system that can have voice, data and facsimile transmissions in the same subband at the same time with high spectral reuse.
