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.

2 Host Installation Guidelines
This section defines host installation limitations for Portable notebooks.
Supporting RF
exposure information is located in Section 4.
2.1 LabelRequirements
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 PortableHosts(WLANantennatouserseparationdistance<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 EndUserInstallation
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.

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

5 IndividualWLANSAREvaluation
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.

6.1 PortableHosts:SumofTotalSAR<SARLimit
A portable collocated transmitter can be operated simultaneously with the MC8355TM
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
Supplement to KDB 616217. The maximum individual SAR value is calculated based on
the WWAN 1-g SAR of 1.290 mW/g.

6.2 PortableHostsMaxCollocatedSARvs.Distance
If the summation of SAR exceeds the FCC limit, collocation is permitted through a Class I
permissive change provided the minimum allowable separation distance derived from the
equation below is satisfied. An alternate equation provides the maximum collocated SAR
based on a specified separation distance as defined in section 4. b) ii) of the Supplemental
note of KDB 616217.
