From : Bruno Clavier, Rhein Tech Laboratories Inc. To: Andy Leimer [email protected] FCC Application Processing Branch Re: FCC ID AXATR-420-A2 Applicant: Ericsson Inc Correspondence Reference Number: 21815 731 Confirmation Number: EA780492 11 February 2002 The following is in response to your inquiries: 1) For AMPS mode, three power levels are listed in the line items. It is unclear why there are three power levels. Please explain including an explanation of how they are selected. Are they switchable? There are 3 power levels for the DM-15 module. Operating Mode Max. Pwr Duty Cycle Class IV operation (AMPS/DAMPS) 0.6W 100% AMPS, 33% DAMPS Class II operation (AMPS/DAMPS) 2.0W 100% AMPS, 33% DAMPS Class I operation (AMPS only) 3.0W 18% The DM15 is capable of operating in either of the modes described above, and can "switch" between modes by reregistering with the cellular system (identifying its CLASS type and technology). 2) The User's Manual mentions a CDPD ensemble. However, there is no line item for CDPD (emissions designator FXW) nor is there any data to support CDPD. The only modulation schemes supported are TDMA and AMPS. Please explain. The DM-15 Module does not support CDPD mode. Please refer to the User's Manual section 3.1.3 where it is stated "Current version of DM-15 does not have CDPD capability" 3) The RF Exposure exhibit (Section 1.2) Mentions that the Class 4 terminal (AMPS/DAMPS) has a variable duty cycle from low to high. Exactly what is the duty cycle for the different applications? The CLASS 1 burst modem transceiver is designed to send a burst of data as a CLASS 1 AMPS cellular mobile, with 3 Watts of RF power at the antenna connector. Typical applications will trigger registrations of less than 120 ms in duration at most every 15 minutes. Once the DM15 determines that data is to be sent, the transceiver initiates a call and then transmits a 4.5-second data burst, which includes a training sequence and V.27 data. The entire transmitter burst duration varies depending on the cellular system network connection time. When the burst modem call is initiated, the DM15 transmits for 1.5 seconds and then powers down for 4 seconds, and then transmits for 1.5 seconds and then powers down for 4 seconds; this process continues until a tone is detected, up to a maximum of eight cycles of 1.5 seconds ON, 4 seconds OFF. The tone is normally detected between two to seven seconds (depending on the cellular system network connection time). Once the tone is detected, the 4.5 second data burst is sent, after which the burst transmitter is disabled by the software for 30 or 50 seconds in order to protect the hardware that has been designed to dissipate heat appropriately for this duty cycle. The disable time is 30 seconds for a sequence of two or less 1.5-second bursts, and 50 seconds for three to eight 1.5-second bursts. For the CLASS 1 burst modem, the extreme case scenario maximum transmission duration is 7.5 seconds over a 41.5-second period which yields the 18% duty cycle. 4) The conducted powers listed in the Test Report do not correspond to the line item power in the application. The Test Report 33.2 dBm (2.1 Watts) for TDMA. The application lists 0.4 watts for TDMA? Please explain. We have added a column of low power TDMA and corrected the power applied for as follows: FCC Rules Parts Frequency Range Output Power (W) Freq. Tolerance Emission Designator 22.901(d) 824-849 MHz 0.6, 2.1, 0.1 29K3DXW 22.901(d) 824-849 MHz 0.6, 2.0, 3.4 0.1 40K0F1D, 40K0F8W 5) Upload the maximum antenna gain and maximum ERP for all modes. The manufacturer does not specify or sell any antenna with this device. The RF exposure exhibit includes a maximum antenna gain for compliance with the minimum separation distance. The User’s Manual specifies the use of an antenna with maximum system gain of 1dBd (i.e., 2.5dBd antenna gain and 1.5dB cable Loss). 6) Show compliance with Part 22.921 provisions for 911 call processing for all AMPS modes. This attestation was uploaded on 11/27/01 and is currently listed under the file name “compliance letter”. Thank you.

Correct the phrase to "to a normally occupied location or person."Submit the corrected page of the User's manual. Correction made and revised manual attached 2) The User's Manual has information for cell phones on page 33. This is not a cell phone so remove this and submit a corrected User's manual. Correction made and revised manual attached 3) The MPE analysis was based on 30 minute averaging. Part 2.1093(d)(2) says that this is not permitted. Please address this issue. Our analysis is based on a mobile device. For this reason we referenced Part 2.1091(d)(2) for radiation exposure evaluation. Our analysis has two parts, Maximum Exposure and Typical Exposure. Maximum Exposure Analysis In our maximum exposure analysis, we provide descriptions of our Class I burst modem and our Class II continuous AMPS mode. For the Class I burst modem, we used the mobile unit's source- based time averaging which as described has a duty cycle of 18.1% over 41.5 seconds total period. This duty cycle is inherent to the device and can not be extended by the user. The Class II AMPS mode is continuous. Therefore, a 1/1 duty cycle was used for this analysis, and a distance from the radiating device to any person of 27cm was specified. Typical Exposure Analysis For the typical exposure, we specified our typical hardware configuration, and based our analysis on Table 1B of 47 CFR 1.1310 for maximum permissible exposure limits for general population / uncontrolled exposure. This table uses an averaging time of 30 minutes. However, since the maximum exposure analysis does not apply this factor for the Class l, and the Class II is continuous in both analyses, we could change the typical to exclude the 30 minute averaging factor. Simply perform the same calculations as in the maximum exposure analysis, but with the typical hardware configuration assumed. We are including a new Exhibit 11 with the calculations performed as mentioned above

Page 2 of 7 1 INTRODUCTION 1.1 PURPOSE OF THE REPORT This technical report is a detailed environmental evaluation of the radiofrequency exposure expected from use of the DM15 transmitter. The analysis below demonstrates that the DM15 device is in compliance with the requirements for maximum permissible exposure (MPE) to radiofrequency exposure as defined in the FCC Rules, 47 CFR 2.1091, as amended. This report serves as the technical basis for the statement of compliance and a request for an exclusion from routine environmental evaluation submitted with the application for type acceptance for the DM15, FCC ID: AXATR-400. 1.2 DESCRIPTION OF THE DM15 DEVICE The DM15 Transceiver has been designed as an OEM module for use by various OEM integrators. The transmitter section delivers up to 3 watts (burst) of output power to an RF connector designed for attachment to a customer-supplied antenna. The transmitter operates in the band designated for cellular telephone use, from 824 to 849 MHz. The transceiver is designed with a form factor suitable for integration into a variety of applications, such as meter reading, security alarm communications, location-on-demand systems, fixed wireless local loop, and vehicular emergency communications. There are two modes of operation: 1. CLASS 1 Burst Modem Transceiver (AMPS only) 2. CLASS 4 Dual Mode Transceiver (AMPS and DAMPS) The CLASS 1 burst modem transceiver is designed to send a burst of data as a CLASS 1 AMPS cellular mobile, with 3 Watts at the antenna connector. Typical applications will trigger registrations of less than 120 ms in duration at most every 15 minutes. Once the DM15 determines that data is to be sent, the transceiver initiates a call and then transmits a 4.5-second data burst, which includes a training sequence and V.27 data. The entire transmitter burst duration varies depending on the cellular system network connection time. When the burst modem call is initiated, the DM15 transmits for 1.5 seconds and then powers down for 4 seconds, and then transmits for 1.5 seconds and then powers down for 4 seconds; this process continues until a tone is detected, up to a maximum of eight cycles of 1.5 seconds ON, 4 seconds OFF. The tone is normally detected between two to seven seconds (depending on the cellular system network connection time). Once the tone is detected, the 4.5 second data burst is sent, after which the burst transmitter is disabled by the software for 30 or 50 seconds in order to protect the hardware that has been designed to dissipate heat appropriately for this duty cycle. The disable time is 30 seconds for a sequence of two or less 1.5-second bursts, and 50 seconds for three to eight 1.5-second bursts. The second mode of operation is as a CLASS 4 terminal, dual mode (AMPS and DAMPS), with nominally 0.355 Watts at the antenna connector. The usage would vary from a low duty cycle with a meter reading application, to a high duty cycle with a fixed telephony appli…
