WiMAX Device Configuration User’s Guide

This screen allows you to specify channel plan settings for Network Discovery and Selection 
(ND&S). The WiMAX Device uses ND&S to establish connections when it is roaming. To do this, the 
WiMAX Device will scan for base stations that are operated by Network Access Providers (NAP) that 
have service agreements with the subscriber’s service provider (Home-Network Service Provider or 

Inner Mode

Sets the EAP-TTLS inner mode.

The WiMAX Device supports the following:

•

MS-CHAP v2 - This is version 2 of Microsoft’s variant of Challenge 

Handshake Authentication Protocol (CHAP). It allows for mutual 

authentication between devices.

•

MS-CHAP - This is Microsoft’s variant of Challenge Handshake 

Authentication Protocol (CHAP). It allows for mutual authentication between 

devices.

•

CHAP - The Challenge Handshake Authentication Protocol (CHAP) uses PPP 

to authenticate remote devices using a three-way handshake and shared 

secret verification.

•

MD5 - Message-Digest, algorithm 5, (MD5) encryption is typically used for 

checking file integrity. Because this encryption protocol contains a number of 

serious security flaws it is generally not recommended that you use it for 

authentication security.

•

PAP - Password Authentication Protocol uses unencrypted plaintext to send a 

passwords for authentication over the network. It’s probably not a good idea 

to rely on this for security.
