It is a data transmission technology developed for use on cellular phone frequencies. CDPD uses cellular channels (in the 800 to 900 MHz range) to transmit data in packets. This technology offers data transfer rates of up to 19.2 Kbps, quicker call set up, and better error correction than using modems on an analog cellular channel. CDPD is based on TCP/IP, the same protocols that power the Internet. See the document on CD-ROM forAll About CDPD Just as you would do with a cell phone, you must first register for service with a local CDPD carrier. The PocketSpider will work with any CDPD carrier.

Shortly after the submittal we encountered manufacturing issues with the device metal housing that we have not been able to resolve in a timely manner. We therefore decided to change to a plastic material for the housing. We recognize that this material change potentially affects the RF and EMC emission characteristics of the device, and the decision was made to re-test to ensure compliance with FCC requirements is maintained. It is therefore respectfully requested that the SAR and EMC test reports submittal date be extended to no later than March 22, 2002. However, we anticipate having the re-tests accomplished and the appropriate test and compliance information submitted prior to that date. In summary, Enfora, Inc. continues to diligently make every effort in good faith to ensure that all applicable FCC requirements will be met for our devices.

FCC ID: MIVCFS0100PS2C 731 Confirmation No.: EA749361 Correspondence Ref. No.: 22616 Dear Joe: On behalf of Enfora Inc. is our response to your e-mail dated April 15, 2002 requesting additional information for the subject application. SAR 1. The 568mW power output listed on the Form 731 was applicable for the original filing of the metal-housed unit, which will no longer be manufactured. The test report re-submission with the plastic housing unit lists the highest ERP measurement as 382mW, therefore we are requesting 382mW power output to be listed on Form 731 and the grant. The SAR rated conducted power level of 708mW is the maximum power level specified by the manufacturer for this device (low channel 991). 2. For future applications we will use the uncertainty budget from the latest draft of IEEE Std 1528. EMC 1. The EUT incorporates a CDPD modem (Model: Enabler-A) that has an individual FCC ID (MIVCDP10EAM). This test report was uploaded with the filing and in the cover letter it was requested that the test requirements for 2.1049, 2.1051, and 2.1055 be referenced to CDPD modem test report. The only difference between the CDPD modem test report and this filing is that the modem has been incorporated into a plastic housing with fixed antenna for use with Sharp SL5000 PDA. 2. Please see attached test data for compliance with the requirements of 2.1049, 2.1051, and 2.1055. The test data submitted for 2.1051 and 2.1053 complies with the requirements of 2.1057. 3. At this time the EUT is designed only for use with the Sharp SL5000 PDA. Furthermore, the RF exposure warning statement in the users manual states that this device must only be used with the Sharp SL5000 PDA to ensure FCC RF exposure compliance. 4. We acknowledge that this application is not for a modular approval. 5. This application is not for a software defined radio authorization. The Form 731 was inadvertently submitted stating an application software defined radio authorization. Please disregard this reference. If you have any further questions or comments concerning the above, please contact the undersigned. Sincerely, Shawn McMillen General Manager Celltech Research Inc.

No.: 22721 Dear Joe: On behalf of Enfora Inc. is our response to your e-mail dated April 26, 2002 requesting additional information for the subject application. SAR 1. The measured ERP of 0.382 Watts is an absolute value and is independent of the measurement uncertainty in the conducted power measured between the two test facilities (692mW measured at our facility, and 708mW measured at Nemko Dallas for the Enabler-A CDPD modem certification). The test unit used for the EMC, ERP, and SAR reports is the same unit. The measurement uncertainty in the conducted power for the Nemko Dallas EMC report is +- 0.6dB and a similar measurement uncertainty exists for the ERP report. It is therefore assumed that the 0.1dB discrepancy in the measured conducted RF output power between the ERP/SAR reports and the Nemko Dallas EMC report is due to measurement uncertainty only. EMC 1. The internal software restricts the device to function with the Sharp PL5000 PDA only. Please see attached letter from the applicant.

CDPD Background The Cellular Digital Packet Data (CDPD) network is a two-way wireless data communication system. This system uses cellular telephone channels to transfer data seamlessly from a mobile end system. CDPD operates within the already existing cellular telephone infrastructure utilizing the idle time that exist on cellular voice channels to send small packets of data, called datagrams, to a designated receiver. Researchers estimate that over 30% of a cellular channel’s airtime is idle, even during heavy traffic. The CDPD system sends down the various cellular channels to locate an open channel. This process is called “sniffing.” Once the CDPD system has located an open channel, the modem begins to send datagrams over the channel to the designated end user. In order that this process does not interfere with the cellular phone transmission, the CDPD system has regulated channel “hops” to ensure that CDPD usage will not block a cellular voice channel for an extended period of time. Also, if a voice channel is activated, the CDPD system detects this voice message and automatically “hops” to the next available idle channel. This process is quite complex. However, the user need not be aware of this process. The CDPD system manages the routing of the individual data packets to the proper destination.
