1. Describe how any software/firmware
updates for elements than can affect the
device’s RF parameters will be obtained,
downloaded, validated and installed. For
software that is accessed through
manufacturer’s website or device’s
management system, describe the
different levels of security as appropriate.
2. Describe the RF parameters that are
modified by any software/firmware
without any hardware changes. Are these
parameters in some way limited such that
any other software/firmware changes will
not allow the device to exceed the
authorized RF characteristics?
3. Describe in detail the authentication
protocols that are in place to ensure that
the source of the RF-related
software/firmware is valid. Describe in
detail how the RF-related software is
protected against modification.
4. Describe in detail any encryption
methods used to support the use of
legitimate RF-related software/firmware.
General Description
Firmware updates will be obtained from the manufacturer’s support website by
the professional installer. The professional installer will install firmware
updates. An RSA digital signature is verified after the firmware has been
transferred to the radio but before it has been saved to non-volatile memory.
Only if the digital signature is valid is the firmware stored to non-volatile
memory.
The support website is protected by HTTPS
(TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256, TLS 1.2). Access to
the support website is using a username and password. User accounts for
the support website are granted only after a customer has been vetted by the
manufacturer's security department.
Center Frequency, Channel Width, Transmit Power, and Dynamic Frequency
Selection can be modified in firmware without hardware changes. The radio
includes a per unit unique, factory loaded firmware option key which dictates
the operational frequency band. The radio firmware does not allow the
operational channel to exceed the authorized frequency band limits (high/low
frequency).
Configuration parameters can only be modified by the professional installer.
An RSA digital signature is verified after the firmware has been transferred to
the unit but before it has been saved to non-volatile memory. Only if the digital
signature is valid is the firmware stored to non-volatile memory.
The radio checks the integrity of the firmware using a 16-bit error detection
code (EDC). A CRC-16 is used to verify that the image has not been modified.
At power-up the module computes a new digest and compares it to a precomputed digest value. If the values are the same the test passes.
Otherwise, the test fails.
Wireless: AES-128 and AES-256
HTTPS: SSLv2*, SSLv3* and TLS 1.0; RC2*, RC4*, DES*, 3DES, AES
SSHv2: 3DES, AES
SNMPv3: DES*, AES
Secure, encrypted file transfer of the firmware is available via HTTPS or SFTP
* Disallowed in FIPS 140-2 compatible mode
5. For a device that can be configured as
a master and client (with active or
passive scanning), explain how the
device ensures compliance for each
mode? In particular if the device acts as
master in some band of operation and
client in another; how is compliance
ensured in each band of operation?
HARRIS CORPORATION
Both master and client modes may be used regardless of the band of
operation.
The radio includes a per unit unique, factory loaded firmware option key which
dictates the operational frequency band. The radio firmware does not allow
the operational channel to exceed the authorized frequency band limits
(high/low frequency).

1. Explain if any third parties have the
capability to operate a U.S.-sold device
on any other regulatory domain,
frequencies, or in any manner that may
allow the device to operate in violation of
the device’s authorization if activated in
the U.S.
2. Describe, if the device permits thirdparty software or firmwareinstallation,
what mechanisms are provided by the
manufacturer to permit integration of such
functions while ensuring that the RF
parameters of the device cannot be
operated outside its authorization for
operation in the U.S. In the description
include what controls and/or agreements
are in place with providers of third-party
functionality to ensure the devices’
underlying RF parameters are unchanged
and how the manufacturer verifies the
functionality.
3. For Certified Transmitter modular
devices, describe how the module
grantee ensures that host manufacturers
fully comply with these software security
requirements for U-NII devices. If the
module is controlled through driver
software loaded in the host, describe how
the drivers are controlled and managed
such that the modular transmitter RF
parameters are not modified outside the
grant of authorization.
HARRIS CORPORATION
Third-Party Access Control
Models sold to commercial customers are frequency band limited via unit
specific, factory-loaded firmware option keys. Models sold to military
customers are not frequency band limited.
No third-party software or firmware is permitted.
Not applicable, the radio is not a module.

1. Describe the user configurations
permitted through the UI. If different levels
of access are permitted for professional
installers, system integrators or end-users,
describe the differences.
a. What parameters are viewable and
configurable by different parties?
b. What parameters are accessible or
modifiable by the professional
installer or system integrators?
(1) Are the parameters in some way
limited, so that the installers will not enter
parameters that exceed those authorized?
(2) What controls exist that the user cannot
operate the device outside its authorization
in the U.S.?
c. What parameters are accessible or
modifiable by the end-user?
(1) Are the parameters in some way
limited, so that the user or
installers will not enter parameters that
exceed those authorized?
(2) What controls exist so that the user
cannot operate the device
outside its authorization in the U.S.?
d. Is the country code factory set? Can it
be changed in the UI?
(1) If it can be changed, what controls exist
to ensure that the device
can only operate within its authorization in
the U.S.?
e. What are the default parameters when
the device is restarted?
2. Can the radio be configured in bridge or
mesh mode? If yes, an attestation may be
required. Further information is available in
KDB Publication 905462 D02.
3. For a device that can be configured as a
master and client (with active or passive
scanning), if this is user configurable,
describe what controls exist, within the UI,
to ensure compliance for each mode. If the
device acts as a master in some bands
and client in others, how is this configured
to ensure compliance?
4. For a device that can be configured as
different types of access points, such as
point-to-point or point-to-multipoint, and
use different types of antennas, describe
what controls exist to ensure compliance
with applicable limits and the proper
antenna is used for each mode of
operation. (See Section 15.407(a))
