MIVWG9701ACDPD/AMPS PCMCIA Wireless Modem

1 REPLY TO REQUEST FOR ADDITIONAL INFORMATION INET SPIDER II MODEM FCC ID MIVWG9701A August 19, 1998 This document has been compiled to reply to a series of questions posed by the FCC as part of the Equipment Authorization Process for the Inet Spider II Modem (FCC ID MIVWG9701A). Each of the questions listed by the FCC Is listed prior to the reply. 1) Please indicate whether and how a specific antenna assembly will always be used with this unit. Note that the antenna will affect the ERP and SAR results. Answer The Spider II will be marketed and sold with the 1/2-wave dipole antenna it was tested with. The absolute most power that can theoretically be transmitted from the unit by design is 28 dBm. There are no antennas on the market today that will attach directly to the unit other than the one tested. The antenna and the PCMCIA transmitter use a subminiature SMC type connector set which is not available as an accessory on the open (accessable by the standard consumer) market. There are a set of follow-on products which are in development at this time, but any items which can affect the radiated power of the device will be tested and submitted for authorization in accordance with Commission regulations. 2) SAR report not received by the Commission Answer SAR report was retransmitted to the Commission during the week of August 10, 1998 3) Please explain why for conducted power output (Pages 15 and 16) the AMPS mode mode is higher while for the ERP the CDPD mode is higher (Page 21). Answer In the case of the conducted power output data, the AMPS mode was reading an average of 1.4 dB higher than the CDPD mode. For ERP, the CDPD mode was reading an average of 2.0 dB higher than the AMPS readings. While both operational modes use the same basic RF sections (giving the same basic transmit power capability) the CDPD signal is spread/distributed differently than the AMPS signal. For the conducted power data, the reported data was derived from the occupied bandwidth plots which were made using a 300Hz/300Hz bandwidth setting. The ERP data was obtained using 100kHz/300kHz bandwidth settings. Based on tests performed on similar products, a 2 shift in relative power can occur between operating modes based on measurement bandwidth. Usually, this shift is 2 to 3 dB, which is on the order of the shift seen here. 4) Please send an occupied bandwidth plot for operation in the wideband data mode. Answer Data for the wideband data operation in AMPS mode is included with this reply. Data is also present for operation in wideband mode for signalling tone plus SAT . Data is presented for three channels across the band. 5) Please send measurement data showing modulation limiting (for voice operation). Answer Modulation limiting was performed using the following procedure: "Perform this test on channel 365. Setup includes compressor enabled and SAT disabled. Input an audio signal at 1 KHz at a level to produce +/-8KHz deviation. Increase level by 20 dB (rise time <0.1 ms)." Test was performed using an HP 8920A test set with the following results: Peak Deviation measured = 11.9 KHz spec = 12 KHz Steady-State Deviation measured = 11.8 KHz spec = 12 KHz 6) Please sned measurement data showing compliance with the audio low pass filter specifications in Section 22.915(d)(1) of the Commissions R&R. Answer The low pass filter data is in paragraph 5.0 and Appendix D of the test report. 7) Your frequency stability rating of 0.0005% does not satisfy the requirement under Section 22.335 of the Commissions R&R. Answer The latest edition of 47 CFR owned by PTI is the October 1996 edition. Section 22.355 of this document quotes the frequency tolerance as being contained in Table C-1 of Scetion 22.357. While Section 22.357 references §22.359 and §22.917, there appears to be no Table C-1 in this edition of Section 22. The figure quoted in the 731 was derived from a similar application. After doing some additional research, it appears that the frequency stability requirement as I understand it is 2.5 ppm. The Spider II easily meets this requirement. The frequency 3 stability data for the Spider II indicates that this unit eaily meets the 2.5 ppm criteria. Assuming that 2.5 ppm is the correct rating, please correct the Form 731 to this figure. 4 OCCUPIED BANDWIDTH DATA SHEET INET SPIDER II WIRELESS MODEM FCC ID MIVWG9701A Sample: FCC #08 Test Date: August 12, 1998Port: Antenna I/O Mode: Wideband DataChannel: 367 COMMENT: Center Frequency = 836.01 MHz 5 OCCUPIED BANDWIDTH DATA SHEET INET SPIDER II WIRELESS MODEM FCC ID MIVWG9701A Sample: FCC #08 Test Date: August 12, 1998Port: Antenna I/O Mode: Wideband Signal with SAT toneChannel: 367 COMMENT: Center Frequency = 836.01 MHz 6 OCCUPIED BANDWIDTH DATA SHEET INET SPIDER II WIRELESS MODEM FCC ID MIVWG9701A Sample: FCC #08 Test Date: August 12, 1998Port: Antenna I/O Mode: Wideband DataChannel: 799 COMMENT: Center Frequency = 848.97 MHz 7 OCCUPIED BANDWIDTH DATA SHEET INET SPIDER II WIRELESS MODEM FCC ID MIVWG9701A Sample: FCC #08 Test Date: August 12, 1998Port: Antenna I/O Mode: Wideband DataChannel: 799 COMMENT: Center Frequency = = 848.97 MHz 8 OCCUPIED BANDWIDTH DATA SHEET INET SPIDER II WIRELESS MODEM FCC ID MIVWG9701A Sample: FCC #08 Test Date: August 12, 1998Port: Antenna I/O Mode: Wideband DataChannel: 991 COMMENT: Center Frequency = 824.04 MHz 9 OCCUPIED BANDWIDTH DATA SHEET INET SPIDER II WIRELESS MODEM FCC ID MIVWG9701A Sample: FCC #08 Test Date: August 12, 1998Port: Antenna I/O Mode: Wideband DataChannel: 991 COMMENT: Center Frequency = = 824.04 MHz

INET Spider II CDPD/CS Modem Technical Summary The INET Spider II product is a CDPD and Circuit Switched cellular modem designed to be compliant with Cellular Digital Packet Data System Specification - Release 1.1 and the Mobile Station - Land Station Compatibility Specification - EIAITIA-553. The modem is a completely self contained unit consisting of a processor and memory for data packetizeing, encryption, encoding, decryption, and decoding. It contains all of the RF transmit and receive circuitry required for AMPS call processing as well as creating and receiving a CDPD data stream on any standard cellular channel. The technology used in the construction of the modem mimics that of an AMPS cellular phone with its wideband data and voice capabilities. In addition, the modem has provisions for performing GMSK data bursts. The product is packaged in a PCMCIA Type II housing and is solely powered and controlled through a PCMCIA PC Card version 2.1 interface. This interface specifies the DC voltage to be provided to the PCMCIA peripheral as a regulated 5 volts +A5%. The interface protocol is design to emulated a standard 16550 UART interface and can be configured on the PC side as a standard Communication Port connection. The data flow into and out of the modem is metered by the modem processor. The data rate of transmission at the antenna terminal is fixed at 19.2 KHz in CDPD mode and 14.4 KHz in circuit switched/AMPS modem mode and is independent of any user application running on the PC side. The modem processor takes care of implementing all protocol controls on the CDPD channel and the aspects of the CDPD channel are not apparent to the users application. The protocol controls in AMPS mode are handled by the processor in conjunction with a TCM8O3O Baseband Processor for Analog Cellular Telephones. Transmitter frequency and emissions type. The transmitter covers the band of 824.010 MHz to 848.970 MHz and is tuned in 30 KHz steps. In CDPD mode, the modulation type is a Gaussian Minimum Shift Keying (GMSK) with BT= .5. The data rate is fixed at 19.2 Kbps. In the AMPS Circuit Switched mode, the modulation type is FSK with a data rate of 14.4 Kbps. Modulation of a carrier is done at the Transmit LO (181.2 MHz) with an I and Q modulator in CDPD mode and a standard FM modulator in AMPS mode. The baseband I and Q waveforms and the FM waveforms, with all of the filter characteristics required to meet the emissions mask, have been described digitally and stored permanently in non-volatile memory. A microcontroller is used to translate the data stream to be transmitted into the appropriate baseband signals. The digital signals are generated at 16 times over sampling, and the analog signals are recreated with an 8-bit digital-to- analog conversion process. This modulation technique requires no tuning or adjustments to meet the emissions mask. Also, because the data is encoded with a pseudo random sequence, the modulation mask is constant and independent of the data being sent. The output spectrum is constant and independent of user controls except for on/off commands. The emissions mask as detailed in the CDPD version 1.1 system specification is: the emission power in either adjacent channel centered +1-30 KHz from the center frequency shall not exceed a level of 26 dB below the mean output power. The emission power in either alternate channel, centered +1-60 KHz from the center frequency shall not exceed a power level of 45 dB below the mean output power. The emission power in either second alternate channel centered +1-90 KHz from the center frequency shall not exceed a power level of 60 dB below the mean output power or -23 dBm, whichever is lower. In AMPS voice mode, the emissions mask is controlled via a modulation limiter in the baseband processor. The modulation deviation is limited to +1-12 KHz maximum. Transmitter power. The transmit output power is classified via the CDPD specification and TIA-553 as class III. Maximum output power is set at 0.6 watts ERP, and is controllable in 4 dB steps from -2 dBW to -22 dBW. The actual level to be used for transmission is determined by a broadcast message sent by the service provider. The user has no provision for setting or adjusting the transmit power. The output power is controlled by a analog voltage generated by a digital-to-analog converter. The actual RF transmit level is sampled by an RF detector and compared to the level requested by the processor and an error voltage is generated which is used to control the gain of the final power amplifier. The output of the RF detector is also provided to the modem processor where a caparison between expected levels of performance and measured levels can be compared to detect failure conditions. Control voltage levels for the various power levels the modem is expected to transmit at are loaded in the modem's nonvolatile memory at time of manufacture. Required Bandwidth. The transmission bandwidth is determined by Carson's Rule: BW = 2(∆f + ~ where, ∆f = frequency deviation and fmod = modulation rate. In CDPD mode, the data rate equals 19.2 Kbps and for equal number of "l's" and "0's", the modulation rate (fmod) = Data rate/2 =e fmod = 19.2Kbps/2 = 9.6 KHz. Further, ∆f = fmod x ~ where, the modulation index (~) equals 0.5 for CDPD. Therefore, Af = 9.6 KHz x 0.5 = 4.8 KHz. BW = 2(4.8 KHz + 9.6 KHz) = 28.8 KHz. In AMPS mode, there are two bandwidth requirements; one for wideband data transmission and one for voice/modem transmission. For signaling tone and wideband data, the frequency deviation is set to 8 KHz and the modulation rate is 10 KHz. BW = 2(8 KHz + 10 KHz) = 36 KHz. For AMPS voice or modem mode, the maximum frequency deviation allowed is 12 KHz at a modulation rate of 3 KHz. BW 2(12 KHz + 3 KHz) =30 KHz. Power requirements. The modem requires 5 volts dc +l-.75 volts for proper operation. The only circuitry that runs off the filtered 5 volts provided by the host is the last two gain stages of t…

These plots show the conducted output power for channels 367, 799 and 991 (836.010, 849.000 and 824.04 MHz) with the bandwidth increased to capture all power distributed due to spreading and modulation. These tests were run for both CDPD and AMPS mode of operation with the EUT in maximum output power mode. The conducted output power of the Inet Spider II modem based on these tests is summarized in the following table: ModeChannelPower (dBm)Power (watts) CDPD36725.000.316 CDPD79923.170.207 CDPD99124.830.304 AMPS36724.830.304 AMPS79922.830.192 AMPS99124.830.304 SAR TEST CLAIRIFICATION PHOTOGRAPH SETUP DESCRIPTION The antenna is connected to the CDPD/CS Modem which is inserted into a laptop computer. The antenna is located directly under the hole, which is the verification point beneath the center of the phantom. The antenna was orientated vertically with the base of the antenna approximately 2cm from the verification point under the phantom. Testing was performed in two configurations. 1.The computer is facing forward with the antenna vertical approximately 2cm from the verification point under the phantom. 2.The computer is facing backward with the antenna vertical approximately 2cm from the verification point under the phantom. Photos of the SAR Setup are shown on the following 2 pages. This represents a worst case location setup. The photos show 3 different angles of the same test setup. The test setup was derived from conversations with FCC personel as what is the appropriate test method for this type of non-phone cellular transmitter. The test was designed to simulate the modem operating in a computer resting in a human lap while the antenna was directly over the human leg. Further, the modem was placed in a continuous transmit mode at maximum power. CDPD is by design, a TDMA type system with a worst case transmit duty cycle of 25 to 30%. The probable reason for the low SAR values is because in practice, the portion of the human body which is less than 20cm from the transmitter is physically below the antenna ground plane. The dipole validation was re-run and the results are in this package.
