Novatel Wireless Inc. Version 2.2 E371 Module Installation and Collocation Guidelines for Host Devices 1.0 Introduction This document provides module and antenna installation guidelines for notebook computers to be authorized for use with the E371 module through the FCC Class I or Class II Permissive Change process. As the grantee Novatel Wireless is responsible for all integrations and must be consulted on all regulatory matters involving the E371.
Novatel Wireless Inc. Version 2.2 The label must state: • This device contains FCC ID: PKRNVWE371 • This device contains IC:3229A-E371 5) These installation guidelines are not applicable to non-notebook host devices or tablet PCs. The installation guidelines are applicable for notebook computers where the E371 antennas and collocated antennas are located in the display portion of a notebook computer.
Novatel Wireless Inc. Version 2.2 2.0 Module Installation Guidelines This section defines host installation limitations for mobile device and portable device hosts. 2.1 Installation Guidelines 2.1.1 Mobile Device Hosts (WWAN to user separation distance >20cm) The E371 module can be installed for use in any authenticated mobile device notebook as long as the antenna gain of the host antenna does not exceed the gain listed in table 1.
Novatel Wireless Inc. Version 2.2 2.1.3 Portable Device Hosts (WWAN to user separation distance ≤2.5cm) The E371 module can be installed for use in a portable device notebook as a Class II change if the antenna separation distance from the user is ≤2.5cm. Table 3.0 describes the limitations if there are no collocated transmitters. Collocated radios must be considered as per FCC KDB 616217 D03 and section 3 of KDB 447498. Section 2.1.
Novatel Wireless Inc. Version 2.2 2.1.5 User Instructions Installers and end user must be provided with specific information regarding FCC RF exposure requirements for Mobile or portable devices. As an example the following text should be provided in the user guide with the regulatory information: This device has been evaluated for and shown compliant with the FCC RF Exposure limits under mobile exposure conditions (antennas are greater than 20cm from a person’s body).
Novatel Wireless Inc. Version 2.2 3.0 Individual SAR Evaluation Portable RF exposure evaluation has been completed based on SAR measurements on a representative PIFA antenna in a representative notebook computer. Integrations that provided ≥2.5cm of separation distance between the edge of the WWAN antenna and the end user orientated at 90 degrees as illustrated in Figure 1-1 and 1-2 do not require additional SAR testing. The measured SAR value at 2.5cm was 0.374W/kg.
Novatel Wireless Inc. Figure 1-2 Version 2.2 Portable Device Notebook Antenna Location – Vertical orientation (Note 1) Minimum Tx Antenna Distance ≥2.5cm Notes: 1. Figures 1-1 and 1-2 are used to illustrate the proper separation distance with different antenna orientations. These illustrations are to be used as a design reference and are not to scale. 2. Mobile Device Definition - FCC defines as a transmitting antenna located at a distance greater than ≥20cm from the user. 3.
Novatel Wireless Inc. Version 2.2 4.0 Collocated Installation Guidelines 4.1 Collocated transmitter application Collocated transmitters can be operated simultaneously with the E371 module, provided the technical parameters listed in Table 4 are maintained and the information specified in Section 5.0 is on file as part of a Class I permissive change. A Class II permissive change is required if the host device does not meet the requirements specified in Table 4 and in section 6.
Novatel Wireless Inc. Version 2.2 5.0 Class I Permissive Change Documentation Requirements The following documentation from KDB 616217 D03 must be supplied by the OEM and approved by the regulatory manager at Novatel Wireless as part of a Class I permissive change request. The following items are required address simultaneous transmission concerns. These documents will be kept on file at Novatel Wireless to support our Class I claim.
Novatel Wireless Inc. Version 2.2 6.0 Simultaneous RF Exposure Evaluation Guidelines For Collocated Transmitters Allowable through a Class I Permissive change 6.1 Mobile Simultaneous Transmission guidelines Collocated transmitters can be operated simultaneously with the E371 module in mobile configurations, provided the technical parameters listed in KDB pub 447498 section 8 are met. These procedures apply to antennas in the display screen for laptop devices.
Novatel Wireless Inc. Version 2.2 These tables are for reference only and are to be used as a guide. Table 5 – The power density calculations for standalone transmitters at an exposure separation distance of 20 cm are shown in table 5 with the declared transmit power and antenna gain values. The calculations are based on a cable loss of 0 dBi. The collocated transmitter values represent worst-case transmit power and antenna gains allowable for use with the E371 WWAN module.

Novatel Wireless Inc. Version 2.2 6.4 Portable Device Hosts: Sum of Total SAR < SAR Limit A portable collocated transmitter can be operated simultaneously with the WWAN transmitter provided the individual SAR results for the portable collocated transmitter are less than the value specified below based on Section 4)a) of the Supp note for FCC KDB 616217 D03. The maximum individual SAR value is based on the worst case SAR recorded on the external antenna at 2.5cm (0.374 W/kg). SARcollocated ≤ 1.6 − 0.
Novatel Wireless Inc. Version 2.2 7.0 Regulatory Statements - Federal Communications Commission Notice (FCC—United States) This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules.
