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 — Transport Layer Security. Provides for certificate-based and
mutual authentication of the client and the network. It relies on client-
side 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. 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
