TO: Joe Dichoso FCC Application Processing Branch Re: FCC ID APV09002 Applicant: Standard Communications Corporation Correspondence Reference Number: 19436 731 Confirmation Number: EA100577 1) Schematics. The exhibit in the schematic folder is not a schematic. Response: Correct Schematics have been uploaded. 2) The Operational description exhibit and Specification manual were identical. Are they suppose to be? This exhibit indicates 631 mW output power. The latest EIRP measurements indicate an EIRP of 30.2 and and ERP of 28.06. What was the conducted output power for these measurements? Correct all exhibits including the operational/specification exhibits with the correct output power. The conducted output power must agree with the latest radiated measurements and antenna gain. Response: Yes, they should be identical. The conducted output power measured is 28 dBm. Please change the 731 form to reflect 631 mW maximum output power, Standard communication wants to be authorized for 631 mW, instead. Conducted output power with antenna gain = 28 dBm + 2.5 dBi = 30.5 dBm (EIRP) ERP = 30.5 dBm – 2.14 dB = 28.36 dBm 3) The manual was not a manual but a specifications document. Please explain/correct. Response: The OEM module is not provide with a user manual, since it will not be sold to the public, instead it is supply with an "interface specification document" in conjunction with "OEM integration guide" for the OEM customers, so they can integrate the module into their final product. The “interface specification manual” was uploaded to the user manual exhibit by mistake. 4) The OEM intallation guide must provide the installer with the proper instructions for compliance. Include insturctions that the antenna must be mounted without a ground plane and must not be co-located. Also, the OEM does not file a Class II permissive change, only the grantee can. Change this statement also. Response: Uploaded calculated RF exposure for Co-location and MPE measurements with a ground plane, to address the RF exposure requirements. For the OEM guide the Class II permissive change statement was removed.

SECTION 22.921: 911 call processing procedure; 911-only calling mode The E911 requirement does not apply in any way to the CMM products as they have no ability to place actual calls to any number, and they have no voice capability. The CRM products (4200) are exempt from the E911 requirement due to the fact that they are principally embedded data transceivers only. The current implementations of the CRM4250 and CRM4200 application interfaces do not support use of the transceiver on a stand-alone basis where internal E911 capability is required. In the event that the customer’s final application has voice calling capability, that application will be required to comply with the E911 requirement. At this time, the G2 CRM products (CRM4200) do not include any special handling provisions for 911 calling. The CRM does provide the application with access to the necessary radio control functions for use in implementing any of the 3 approved call-handling scenarios. We do plan to implement and offer internal E911 call processing features in the future to simplify customer applications where this capability is required. The timeframe is within 2001 (target mid- year). The specific scenario(s) to be implemented have not yet been determined although it is anticipated that it will be a fully self-contained process, given the embedded nature of our products.

Fcc_stmt.doc 4/9/01 Statement Regarding Compliance of Standard Communications Wireless Modules with Regulations for Human Exposure to Radiofrequency Emissions In August 1996, the Federal Communications Commission (FCC) adopted a Report and Order in ET Docket 93-62 amending its rules for evaluating the environmental effects of radiofrequency (RF) electromagnetic fields. Specifically, the FCC adopted new guidelines and procedures for evaluating human exposure to RF emissions from FCC- regulated transmitters and facilities. As a part of this proceeding, new limits were adopted for human exposure to RF emissions from certain mobile and portable devices. The wireless modules offered by Standard Communications’ Wireless Datacomm Division are subject to these amended rules and associated orders. MPE calculation were made for the CRM 4200 unit, with the highest gain antenna being 2.5 dBi, which yield a 1.07 Watt ERP (12.4 cm). Per Section 2.1091 paragraph C, the CRM 4200 is exempt from routine evaluation. Please refer to the excel spreadsheet, label “MPE Caculations” showing the calculated distance and power values in ERP and EIRP. But, based upon calculations using a standardized configuration, the models mention above is in compliance with the “Maximum Permissible Exposure” (MPE) limits as defined in the rules for “mobile” devices. Under these rules, “mobile” devices are those devices where the typical installation configuration has a spacing of at least 20 centimeters between the antenna and any nearby human(s). The rules relating to this matter and the related performance measures are heavily influenced by the final packaging and antenna configuration of the end-product as well as the installation environment. With an OEM module such as those provided by Standard, it is impossible for Standard to accurately predict the performance of every possible application configuration and guarantee compliance with the rules. As a convenience to Standard’s customers, Standard does secure FCC Equipment Authorizations for most of its OEM wireless modules. These authorizations are secured using a typical configuration that assures compliant operation within the normal operating ranges, and transmitter input signal ranges of the device. This standardized configuration also assumes a typical antenna configuration. Customers and end-users are cautioned that operation in configurations differing from the typical configuration may result in transmitter operation outside of the limits permitted under the rules. The pass-thru of Standard’s equipment authorization is invalid if the device is operated in a configuration inconsistent with that under which it was authorized. Customers desiring to operate these devices under different configurations of antenna, Fcc_stmt.doc 4/9/01 power, grounding, etc. must have their specific configurations evaluated by a competent RF engineering and certification laboratory to ensure compliance with the rules and secure additional approvals as necessary. Ultimately, the company offering a final product to the market is responsible for full compliance with the FCC rules. All customers are strongly encouraged to have any product that they develop thoroughly tested to insure proper RF operation and compliance with all applicable rules. As a reminder, Standard also conducts EMI measurements under Part 15 as part of the authorization and certification process. This is done to insure that the modules are in compliance with the established EMI limits. However, all final customer applications must be re-evaluated and certified for compliance under Part 15 prior to the product being commercially offered.

Integration Guide Cellular Radio Module CRM4200/4250 6 March 27th, 2001 ANTENNA CONSIDERATIONS The diagrams below illustrate the different antenna selections used for applications. Each example has implementation criteria due to its performance and operation. A. The quarter wave antenna is small and lends itself well into tight applications where space is critical. A ground plane radius of greater than 100mm is required for proper operation. Failure to provide this grounding will result in erratic radiation patterns, signal loss and mismatched impedance to the CRM4200/4250. B. The half wave antenna is twice the length of the quarter wave. It’s properties require less ground plane which make it more ideal for applications that have less metal mass. The antenna has a better radiation pattern. C. The dipole antenna provides a ground-plane-free operation with optimum gain for its size. This antenna provides its own ground-radiating element and can be used with plastic enclosures. D. The loading coil antenna is the largest of the four mentioned but has a gain advantage over the dipole. The loading coil located in the center of the antenna provides electrically longer antenna to radiate the signal better. Standard Communications Corp.

In § 2.1091(b), a mobile device is defined as a transmitting device designed to be used in other than fixed locations and to generally be used in such a way that a separation distance of at least 20 centimeters is normally maintained between the transmitter's antenna and the body of the user or nearby persons. In accordance with § 2.1091(c), mobile Cellular devices are categorically excluded from routine environmental evaluation for RF exposure prior to equipment authorization or use if their ERP is less than 1.5 W (31.7 dBm). The CRM4200 technical specification mandates a separation distance of at least 20 cm between the unit's antenna and the body of the user and nearby persons for ALL uses and applications. The CRM4200 is not designed for or intended to be used in portable applications, as defined in § 2.1093 (within 20 cm of the body of the user), and the technical specifications and OEM instructions contains specific language prohibiting such uses. Finally, to provide proof that the CRM 4200 is categorically excluded from a routine environmental evaluation for RF exposure, an MPE calculation is provided and has been uploaded, which is label “revised MPE calculation”. The customer will be providing a Centurion (M/N: EXE-821-SM), which has a gain of 2.5 dBi. This will be the only antenna provided by the customer. The maximum power that they want authorization is 600 mW. Using the provided information the following EIRP or ERP can be calculated. 600 mW (27.78 dBm) EIRP = 27.78 dBm + 2.5 dBi = 30.28 dBm ERP = 30.28 dBm – 2.14 dB = 28.14 dBm or .651 Watts Using the provided antenna gain, the total power, in ERP, comes out to be .651 Watts. This is below the 1.5 Watts (ERP), which excludes the CRM4200 from routine environmental evaluation for RF exposure.
