The Authentication tab on the Add Profile screen displays the following
items:
Enable Authentication — Enables user authentication for connection to
the network.
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-MSCHAPV2 — 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 — Transport Layer 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 Identity — 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.
Certificate in EEPROM — Indicates if the device certificate, key, and
password is included in memory on the device. If the certificate files are
not in EEPROM, they can be located or specified using the following fields.
◆ Client Certificate — The name of the file on the host PC that contains
the device security certificate. The browse button can be used to locate
the file.
◆ Client Private Key — The name of the file on the host PC that contains
the encryption key for use with the security certificate.
◆ Client Private Key Password — The required password for the
private key.
User name — A text string used by EAP-TTLS-MSCHAPV2 to identify the
user to the authentication server.
Password — The password used by EAP-TTLS-MSCHAPV2 to confirm the
identity of the user to the authentication server.

PKMv2 Enable — PKMv2 (Privacy Key Management version 2) is the
standard security solution for WiMAX networks. The security protocol
provides mutual authentication of the subscriber station and base station,
as well as distributing traffic encryption keys. It is also used to transport
EAP (Extensible Authentication Protocol) messages.
ARQ Enable — The ARQ (Automatic Repeat reQuest) mechanism is an
optional part of the WiMAX MAC layer and a protocol for error control in
data transmission. When a packet error is detected, the transmitter is
automatically requested to resend the packet.
Idle Mode Enable — Idle mode enables power savings for the WiMAX
adapter. The feature can turn off the MS and not be registered with any
base station, and yet receive downlink broadcast traffic.
Invert MSK — Inverts the Master Session Key used in the EAP process.
Handoff Enable — Enable handoffs when moving between base stations.
Auto Sync Up — Enable automatic synchronization with the base station
signal.

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. Subscriber stations measure the received CINR
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 radio signal. The amount of
information that can be transmitted in a radio 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.
