The system locates tagged assets by a process involving redundant triangulation. Each tag autonomously emits a 2.4 GHz direct sequence spread spectrum (DSSS) radio signal at predetermined blink rate. Each tag’s blink rate is randomized around its predetermined value to minimize the number of collisions between transmissions made by different tags. The signal emitted by the tag is received by a minimum of four DSSS receivers each of which are capable of decoding that tag’s transmission. A typical transmission contains a preamble which is used to synchronize the receiver, the tag’s serial number which identifies the tag, a status word which monitors various tag functions, data stored in the tag’s memory and finally a CRC used to assure that the tag’s message is correct as received. Tag configuration parameters such as blink rate and user data to be stored in memory are loaded into the tag using a device called a Hand Held Communicator (HHC). The HHC consists of a Type II PCMCIA card inserted into a laptop or handheld PC. The PCMCIA card contains a short range (2 to 10 feet) radio transmitter and receiver which communicates with a very low power transmitter and receiver contained in each tag. This short range communication link operates at 2.4 GHz. The modulation scheme used by the PCMCIA card was chosen to minimize power consumption by the battery operated tag receiver. The DSSS transmitter allows the system to locate users of the HHC anywhere in the service area covered by the system. Hand Held Communicator The WiData Corporation Communicator PCMCIA card allows the handheld computer, laptop computer, or any other computer with a PCMCIA slot to operate as a Firefly Communicator. Tag-to-Communicator bi-directional data transfers are accomplished using the OOK/FSK RF modulation link. The Communicator-to-RF Processor DSSS RF modulation link is one-way only. Figure 1 shows a typical WiData Firefly System. The handheld computer can also include standard WLAN and Bar Code Scanners to further enhance system capabilities. Power Management The Hand Held Communicator PCMCIA power consumption is handled by the application software installed on the handheld computer. The software will power down the card during periods of in-activity. Any time the Hand Held Communicator is not in use, the handheld computer should be installed into its battery charging cradle.

The material addresses CFR 47 Part 15.203 requirements. WiData Model HPC-2000-00AA Hand Held Communicator PCMCIA Card Statement Addressing CFR 47 Part 15.203 Antenna Requirements The WiData model HPC_2000-00AA Hand Held Communicator is a Type II PCMCIA card based system consisting of a 2.4 GHz direct sequence spread spectrum transmitter and a 2.4 GHz on-off keyed short range transmitter and receiver. A single antenna supports all transmission and reception modes. The Type II PCMCIA card is only 0.16 inches (5 mm) thick. and is inserted into a host computer so that only a 2.12 inch (54 mm) by 0.16 inch (5mm) face is available for connection to external devices such as antennas. The 5 mm thickness severely restricts the number of options for coaxial connectors that are adequate at 2.4 GHz. We have chosen to use a MMCX connector (Amphenol p/n 908-22100) on the card. This connector series is never found in retail establishments or at distributors of standard electronic components. It is made by a very limited number of vendors and is available only directly from these vendors or their representatives. Because of the extremely small size of the mating plug it can not be practically installed on a coaxial cable without special tools which again are only available from the connector vendor. Antennas supplied with hand held computers intended for use with PCMCIA cards containing 2.4 GHz radio equipment commonly have coaxial cables terminated with MMCX plugs. WiData has chosen this MMCX connector because it has been approved in the past for similar PCMCIA applications and because it is used on antennas supplied on hand held computers designed to be used with 2.4 GHz wireless PCMCIA devices and because it is not commonly available to our end users. For these reasons we believe that the Hand Held Communicator PCMCIA Card fully complies with the requirements of CFR 47 Part 15.203. Sincerely, John A. Eisenberg Executive Vice President

WiData Firefly System Processing Gain Measurement The processing gain for the Firefly system is measured using the CW jamming margin method as described in CFR 47 Part 15.247(e)(2) where Gp = S/N 0 + Mj + Lsys. For this system, the BER requirements are derived from the required message error rate because the direct sequence spread spectrum (DSSS) receiver can provide metrics for message errors, but not actual bit errors. (The system uses burst transmissions, and the bursts are discarded if a single bit error occurs.) The remainder of this memo includes the derivation of the S/N 0 of the Firefly System a description of the test setup and procedure, a summary of the results of the testing and an attachment, which contains the detailed data from the test. Both the WiData Model TFF-1000-00AA Tag and HPC-2000-00AA Handheld Communicator contain identical RFIC based transmitters and transmit the same DSSS protocol. The data below was measured with the Model HPC-2000-00AA Handheld Communicator. The receiver used for this test is a WiData Model FEC-3500-00AA. WiData’s Firefly system uses a 48-bit message length. The nature of the Firefly System is such that is not practical to directly measure processing gain by observing signal to noise ratio at the output of the receiver’s demodulator with and without the presence DSSS spreading code. Therefore we chose to make the CW jammer measurement using the WiData HPC-2000-00AA Handheld Communicator. This is because the Handheld Communicator could be placed in a mode where it repeated it DSSS message in a loop at a rapid rate. The TFF-1000-00AA Tag blinks randomly at a much slower rate. This made it impractical to measure the required 1220 data points in a reasonable timeframe. The tag and Hand Held communicator have identical RFIC based transmitters, employ the same parts and transmit identical DSSS protocols. They are both used with and demodulated by the same receiver. Because the tag and Handheld are essentially identical DSSS emitters we are submitting data for the Handheld only and request that it be applied to both products. The WiData tag digital functions are contained in a CMOS gate array. The tag’s logic does not permit it to be placed in a continuous DSSS test mode as is available in the Handheld Communicator. The CMOS gate array is masked silicon and can not be modified to add special test modes. The result of the test is a measured processing gain of 15.9 dB. This result satisfies the CFR 47 Part 15.247 requirement for a minimum of 10 dB of processing gain. BER Requirements Derivation A message throughput rate of 75 percent is acceptable for reliable operations. The burst transmission consists of 48 bits and a single bit error will cause a message error. The message error rate is related to the BER by a simple probability equation. The probability of having zero bits in error out of a 48-bit transmission is given by, Pm = (1 – Pb) L Where,Pm is the probability of receiving a message without errors Pb is the bit error rate probability or BER L is the length of the message Solving for Pb, given Pm = 75 %, we have, Pb = 1 – (Pm) (1/L) or, Pb = 1 – (.75) (1/44) = .00598 Test Setup and Procedure The processing gain test set-up consists of the following equipment connected as shown below. • WiData Model HPC-2000-00AA Handheld Communicator (unit under test) • Notebook Model 6100T Laptop Computer to control UUT • HP8648c signal generator • HP 436a and HP 8484a power meter • HP 797D directional coupler • HP 8494A and HP8496A step attenuators • WiData Model FEC-3500-00AA DSSS burst receiver Jammer/Signal Ration Test Setup HPC-2000-00AA WiData PCMCIA Card Notebook 6100T Laptop Computer HP-8648C Signal Generator HP-797D -20 dB Directional Coupler HP-8494A & HP-8496A Step Attenuators (0-81 dB) A FEC-3500-00AA WiData DSSS Receiver HP-8484A Power Head HP-436A Power Meter Connect to point A calibration The test was conducted by first putting the Handheld Communicator in a continuous DSSS test mode and measuring the power level on the power meter. The jammer level was then set to 0 dB relative to the carrier level and measured using the power meter and the signal generators internal attenuator. A step attenuator was used to adjust the jammer level relative to the signal. The Handheld Communicator left in the continuous DSSS test mode. Message error rate software was written to record the number of good messages received in a group of 128 messages. The passband of the system is +/- 30.5 MHz, so there are 61MHz/50KHz = 1220 test points across the passband of the system. The jammer frequency was set to the lowest frequency in the passband and the jammer level was adjusted until the good message rate measured 96/128 for the nominal 75% throughput. The jammer was then stepped across the passband in 50 KHz increments and the highest jammer level which still allowed 75% throughput was logged at each frequency. This information was recorded in an Excel spreadsheet. Test Results Using the jamming margin method, the processing gain (in dB) is defined as Gp = S/N + Mj + Lsys The required S/N, was derived from the equation Pb = ½ exp(-S/N) for non coherent DBPSK waveforms. Using the BER of .00598 determined above resulted in a S/N of 6.5 dB. To determine Mj, the test data from the jamming margin test was utilized. An Excel Spreadsheet showing the maximum J/S ratio which allowed a good message rate of 75 % for each of the 1220 frequencies in the passband has been submitted as a separate document. A graph summarizing this data is shown in Attachment A. After removing the J/S ratios of the worst 20 %, the lowest remaining J/S level is 7.4dB. Given the design parameters of this system, Lsys was estimated to be 2 dB. Combining these results, the measured processing gain is: Measured Processing Gain = 6.5dB + 7.4dB + 2dB = 15.9 dB ATTACHMENT A Jammer/Signal 2.0 4.0 6.0 8.0 10.0 12.0 14.0 16.0 Jammer Frequnecy (MHz) Frequency (MHz) Signal PowerJammer PowerJammer/Signal 2,411.2…
