3/8 MC8355TM Module Installation and Collocation Guidelines for Lenovo Portable Host Devices 1 Introduction This document provides module and antenna installation and collocation guidelines for Lenovo tablet computer model TP00019A to be authorized for use with the MC8355TM module through a FCC/IC Class I Permissive Change process in accordance with the Supplement Note to FCC KDB 616217. The following installations for Portable host configurations are addressed in this document. 1) The MC8355gwTM module can be installed as a standalone transmitter in a Portable notebook/netbook or Tablet (hereafter called Portable notebook) meeting the following conditions: Portable notebooks that meet the technical parameters are defined in Section 2 and Section 3. These parameters define the Portable notebook configuration used as the baseline host to evaluate SAR. Alternatively, a more conservative host approved through a Class II Permissive change can also be referenced as the conservative baseline where new Portable notebooks with greater antenna separation distance or lower SAR can be added through a Class I Permissive change. 2) Allow the host device collocated transmission with the MC8355TM module approved under FCC ID: N7NMC8355-L, IC: 2417C-MC8355 through a Class I permissive change process. The collocated transmitters must meet the technical requirements defined in Section 3. 3) Allow end-user installation provided module/notebook Two-Way Authentication has been addressed so that modules can only be activated in approved notebooks. Other configurations not specifically described in this document may be authorized in a Class I permissive changes through coordination with Sierra Wireless Incorporated to verify that all technical requirements defined in Supplement Note to FCC KDB 616217 or other relevant FCC specifications are adequately addressed. The installation and collocation guidelines are applicable only for Tablet computers where WWAN and collocated antennas are located in the keyboard section or display portion of a Tablet computer where SAR evaluation is completed with the proper antenna separation distance to the keyboard or display antenna as defined in KDB 616217 and Section 4 of KDB 447498. Any collocated transmitter or antenna that does not meet the technical requirements defined in this document requires a Class II permissive change to authorize simultaneous transmission.
4/8 2 Host Installation Guidelines This section defines host installation limitations for Portable notebooks. Supporting RF exposure information is located in Section 4. 2.1 LabelRequirementsThe FCC and Industry Canada IDs must be permanently affixed on the exterior of the Portable notebook or readily accessible under a panel or battery pack of the host device that cannot be separated from the host device itself. 2.2 PortableHosts(WLANantennatouserseparationdistance<20cm)The MC8355TM module can be installed for use in any authenticated Portable notebook device with the WLAN antenna limitations defined in Table 1 in Section 3. 2.3 EndUserInstallationTwo-way authentication documentation must be submitted as part of a Class II permissive change allowing end-user installation into Portable notebooks that utilize the method of authentication.
5/8 3 Collocated Installation Guidelines Collocated transmitters can be operated simultaneously with the MC8355TM module, provided the technical parameters listed in Table 1 are maintained and the information specified in Section 4 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 1 and in section 6.

6/8 4 Class I Permissive Change Documentation Requirements The following documentation must be kept on file to allow simultaneous transmission as part of a Class I permissive change. A Class II permissive change is required if the technical requirements of KDB 616217 cannot be met. • List of all collocated transmitters with FCC and IC IDs • Verification that all WWAN and WLAN antennas are >5cm from external USB, PCMCIA or other notebook I/O ports that support an external plug-in transmitter. • Drawings showing antenna locations and separation distances • Antenna types with respective dimensions and far field antenna gains • Specific module to antenna RF coaxial cable losses • RF exposure analyses demonstrating compliance with Section 4) of KDB 616217 as shown below
7/8 5 IndividualWLANSAREvaluation Portable RF exposure evaluation has been completed based on SAR measurements on the Portable notebook computer (Lenovo Model: TP00019A) that provided 1.5 cm of separation distance between the WWAN antenna and the end user as illustrated in Figure 1. The measured 1-g SAR for the WWAN configuration was 1.290 mW/g (1g) as reported in the Class II Permissive Change application. New Portable notebooks with greater antenna separation distance or lower SAR can be added through a Class I Permissive change.
