COMPLIANCES

FEDERAL COMMUNICATION COMMISSION INTERFERENCE STATEMENT

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. These limits
are designed to provide reasonable protection against harmful interference
in a residential installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct
the interference by one of the following measures:

◆ Reorient or relocate the receiving antenna

◆ Increase the separation between the equipment and receiver

◆ Connect the equipment into an outlet on a circuit different from that to

which the receiver is connecte d

◆ Consult the dealer or an experienced radio/TV technician for help

This device complies with Part 15 of the FCC Rules. Operati on is subject to
the following two conditions : ( 1 ) T hi s d e v ic e m ay no t c a us e harmful
interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.

FCC Caution: Any changes or modifications not expressly appro ved by the
party responsible for compliance could void the user's authority to operate
this equipment.

IMPORTANT NOTE:
FCC RADIATION EXPOSURE STATEMENT

This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. End users must follow the specific operating
instructions for satisfying RF exposure compliance. To maintain compliance
with FCC RF exposure compliance requirements, please follow operation
instruction as documented in this manual.

This transmitter must not be co-located or operating in conjunction with
any other antenna or transmitter. The availability of some specific channels
and/or operational frequency bands are country dependent and are
firmware programmed at the factory to match the intended destination.
The firmware setting is not accessible by the end user.

this device with other transmitters at the same time may exceed the FCC
RF exposure limit and such usage must be prohibited (unless such co­transmission has been approved by FCC in the future).

SAR (SPECIFIC ABSORPTION RATE) COMPLIANCES STATEMENT

SAR compliance has been established in typical laptop computer (s) with a
USB slot, and the product can be used in typical laptop computers with
USB slots. Other applications, such as handheld PCs or similar devices have
not been verified and may not be in compliance with related RF exposure
rules and such use shall be prohibited.

EAP Method — Selects the Extensible Authentication Protocol (EAP)

method to use for authentication. When EAP-TTLS or EAP-TLS is selected,
the appropriate parameters need to be configured.

◆ EAP-TTLS-MS-CHAP-V2 — Tunneled Transport Layer Security with

Microsoft’s version 2 of CHAP (Challenge-Handshake Authentication
Protocol). This security method provides for certificate-based, mutual
authentication of the client and network through an encrypted channel.
Unlike EAP-TLS, EAP-TTLS requires only server-side certificates. The
MS-CHAP protocol requires a user name and password to be
configured. The user name and password can be up to 50 characters.
(The following characters are not permitted; /\|”?@#$%^&*():;<>,. )

◆ EAP-TLS — T ransport Lay er Security . Provides for certificate-based and

mutual authentication of the client and the network. It relies on client­side and server-side certificates to perform authentication and can be
used to dynamically generate user-based and session-based encryption
keys to secure subsequent communications between the user and the
network.

Outer NAI —The Network Access Identifier (NAI) text string that is used
to identify the home authentication realm for device authentication during
roaming. The NAI string (defined in RFC 4282) is used to proxy an
authentication request to another remote server. The authentication is then
performed using the unique X.509 authentication certificate included with
the device. The string can be defined by three methods:

◆ MAC: Uses the device MAC address as part of the identity.

◆ RANDOM: Uses a generated random number of 26 hexadecimal digits.

◆ CUSTOMIZE: Allows the whole string to be defined as required.

Trust CA Certificate — The security certificate issued by a recognized
certification authority (CA) that is used for mutual authentication with the
authentication server when EAP-TLS is used. The browse button can be
used to locate the file on the host PC.

User name — A text string used by EAP-TTLS-MS-CHAP-V2 to identify the
user to the authentication server.

Password — The password used by EAP-TTLS-MS-CHAP-V2 to confirm the
identity of the user to the authentication server.

GLOSSARY

AUTHENTICATION The process to verify the identity of a subscriber requesting network

access.

BANDWIDTH The difference between the highest and lowest frequencies available for

network signals. Also synonymous with network speed, the actual speed of
data transmission through a medium.

BASE STATION A WIMAX service provider’s equipment that is installed at a fixed location

to provide network connectivity for subscriber stations within a defined
service area.

CINR Carrier-to-Interference-Plus-Noise-Ration: A measurement of the channel

quality in a WiMAX link. Subscri ber stations measure the receive d CIN R
and send the information back to the base station. The base station can
then adjust modulation and coding for the link to optimize throughput.

CENTER FREQUENCY The radio frequency at the center of a WiMAX channel. WiMAX channels

can be of different widths (the channel bandwidth) and the transmitted
radio signal is spread across the full width of the channel.

CHANNEL BANDWIDTH The range of frequencies occupied by a WiMAX r adio signal. The amount of

information that can be transmitted in a r a dio signal is related to the
channel bandwidth, which is measured in Megahertz (MHz). WiMAX
supports a range of channel bandwidths that can be defined by the service
operator depending on performance requirements, operating preferences,
and regulatory constraints.

CPE Customer-Premises Equipment: Terminal equipment provided by a service

provider that is located at a subscriber’s premises and supports a
communication channel between a customer and the service provider.

CPU Central Processing Unit: The CPU, or processor, is the part of a computer

where most calculations take place. In most of today’s PCs, the CPU is
contained on a single chip. The type and speed (in GHz) of a CPU largely
defines the processing power of a computer.

allocation of reusable network addresses and additional configuration
options.

ENCRYPTION Data passing between a base station and subscribers uses encryption to

protect from interception and evesdropping.

EAP Extensible Authentication Protocol: An authentication protocol used to

authenticate subscribers. EAP is used with TLS or TTLS authenticati on to

RAM Random Access Memory: The memory in a computer where the operating

system, application programs, and other data currently in use are stored.
RAM is volatile memory where data is lost when the computer is turned off.
Having more RAM in a computer reduces the time the processor takes to
read data, which increases overall computer performance.

RSSI Receive Signal Strength Indicator: A measurement of the strength of a

received wireless signal. The higher the RSSI value, the stronger the
received signal from the antenna.

ROAMING The process where a WiMAX subscriber can move onto another operator’s

network while maintaining a continuous connection.

SOFDMA Scalable Orthogonal Frequency Division Multiple Access: The air interface

defined for mobile WiMAX. SOFDMA is a multiple access method that allows
simultaneous transmissions to and from several users, employing a
subchannel structure that scales with bandwidth.

connectivity with a WIMAX network.

TCP/IP Transmission Control Protocol/Interne t Pr otocol: Protocol suite that

includes TCP as the primary transport protoc ol, and IP as the network layer
protocol.

TLS Transport Layer Security: An standard defined in RFC 5216, EAP-TLS is an

authentication protocol that provides strong security through the use of
client-side certificates.

TTLS Tunneled Transport Layer Security: EAP-TTLS is a protocol extension of
