June 15, 1999 Federal Communications Commission 7435 Oakland Mills Road Columbia, MD 21046 ATTN: Applications Examining Division RE: io Wave, Inc., Certification Application; FCCID: NK4-7039795714 Gentlemen: Please find the enclosed application for Certification of a Part 15 Direct Sequence Spread Spectrum Transmitter. TheModel 2.4 GHz ioLink4/ioLink1 Wireless Systemwill interface with a terminal via RS-232 port, and therefore may be considered a Class A Digital Device as well. Class A is justifiable since the system is intended for, and marketed only to commercial operators. The system has high quality with fast T1 data through-put, as well as being priced way over any consumer product. Commercial applications are outlined in the User Manual. The 56 cm minimum safe distance limit for 1 mW/cm RF exposure, as shown in the User ManualAppendix C1,was calculated fromFCC OET 65 Appendix B, Table 1Bguidlines for General Population/Uncontrolled Exposure. This calculation was based on the highest EIRP possible from the system, considering maximum power and antenna gain. The formula used was: S = (Po*G)/(4*pi*r^2) The RF unit incorporates a standard N connector to the antenna, therefore requiring professional installation. Appendix C of the User Manual specifies that only trained ioWave certified technicians should install theioLink4/1. There are many technical steps needed to install an operating full-duplex system, as outlined in the manual. These include antenna support structure, site survey, antenna alignment, test and troubleshoot. All systems sold to businesses are installed by io Wave, Inc. Marketing is limited sales by authorized dealers. Your consideration is much appreciated. Sincerely, Steven Dayhoff Chief Engineer

Theory of Operation. The iolink 1 is a full-duplex Tl rate radio operating in the 2.4 GHz ISM band. The data transmitted through the iolink 1 is processed in the following sequence: LIU <-> FEC <-> Baseband (DSSS) <-> IF <-> RF ------ RF <-> IF <-> Baseband <-> FEC <-> LIU Below, TX indicates the data stream toward the antenna and RX indicates the data stream from the antenna. Line Interface Unit TX: The LIU converts the tip and ring input from the external device to clock and data (RCLK and RPOS) which are passed to the FEC. The data from the connections, RJ-48 and BNC, pass through a transformer, fuses, lightning protection and voltage limiting diodes on the input lines. RX: The data received from the link is converted to tip and ring. The data to the output connections, RJ48 and BNC, pass through a transformer, fuses, lightning protection and voltage limiting diodes on the output lines. Forward Error Correction TX: RCLK and RPOS pass from the LIU to the FEC ASIC. The data is encoded using Rate 3/4 punctured convolutional coding which increases the data rate from Tl (1.544 Mbps) to 4/3 Tl (2.059 Mbps). The data is passed to the Spread Spectrum ASIC. RX: The received data from the DSSS ASIC is decoded using a Viterbi decoder. Baseband TX: The baseband processing is performed by a Spread Spectrum ASIC and an A/D. The data bits from the FEC (encoded RPOS) are processed as pairs of bits, one bit for the in-phase channel (1) and one for the quadrature channel (Q); thus, two bits make one QPSK symbol and the symbol rate is half the encoded data rate. The QPSK symbols are then processed sequentially by the differential encoder, the PN code modulator and the QPSK modulator. The result is a digitized IF signal which has been spread by the PN code modulator. A 10 chiptsymbol PN code is used. The I and Q channels for the symbols are passed to the IF section. RX: The received signals from the IF section, RXI and RXQ, are first processed by the AID which samples at a rate equal to the data rate * code length * 2 = 41.173 MHz. The digitized signal is then passed to the Spread Spectrum ASIC and processed by the digital downconverter which converts it to baseband. This is followed by the matched filter which samples I and Q twice per chip to compute the cross-correlation and then the symbol tracking processor which detects the optimal de-spread I and Q symbols. The de-spread I and 0 symbols are sent to the differential demodulator, where the current and previous symbols are processed in order to identify the encoded bits. The bits are processed by the output data processor to produce a serial bit stream which is transmitted to the FEC on RXOUT. lntermediate Frequency TX: The symbols from the Baseband are sent to the IF section as TXI and TXQ. These are mixed with a 1 1 0 MHz oscillator (with a 90 degree phase difference for I and Q) to bring them up to the IF frequency. Then, I and Q are summed and the resultant signal is passed through an AGC and filter (25 MHz bandpass) befbre being sent to the RF unit for upconverting to the 2.4 GHz transmission frequency. RX: The down-converted 70 MHz signal is passed through an AGC and bandpass filter, then decomposed into I and Q. The analog symbols, RXI and RXQ, are passed through the A/D as described above. Radio Frequency Unit TX: The llO MHz IF signal is passed through an AGC circuit, then up-converted to 2.4GHz.This is then amplified to +25 dBm and passed through a filter to the antenna. RX: The signal received from the antenna is passed through an AGC circuit, then down-converted to 70 MHz and filtered before being passed to the IF cable.

RF Exposure Calculations: The following information provides the minimum seperation distance for the dish antenna provided with the ioLink4/1 system, as calculated fromFCC OET 65 Appendix B, Table 1BGuidlines for General Population/Uncontrolled Exposure. This calculation is based on the highest EIRP possible from the system, considering maximum power and antenna gain. The formula used was: S = (Po*G)/(4*pi*r^2) Where S = 1.0 mW/cm^2 for 2400 MHz. Where Po = 315 mW max. For: 21 dB Dish Antenna - Comsat Model P-24A24N ......r = 56 cm The following statement will be presented in the ioLink4/1 User Manual, Appendix C1: WARNING In order to comply with the FCC adopted RF exposure requirements, this transmitter system will be installed by the manufacturer's resaler professional. Installation of the 2 ft. parabolic dish antenna must be performed in a manner that will provide at least 56 cm clearance from the front side of the dish, to any personnel such as employee or member of the public.
