API/ Interface Library

API provides application interfaces to:

Control and Monitor (connect/disconnect, diagnostics) Configure (Idle mode, SNMP MIBs)

Calibrate (MAC Address, RF, Security Certificates, etc.)

Command-response type of interactions

Implemented in loadable DLL

Commands are ALWAYS asynchronous registered functioncalled back for all responses

C based implementation. Ensures portability to other operating

systems

Sample applications (command line Connection Manager) todemonstrate usage of these APIs

Basic Host API Call Set

Link: Link Up/Link Down. Performs net entry/dereg

RSSI: RSSI level. Periodically/Stop returning RSSI level

CINR: CINR Level. Periodically/Stop returning CINR level

Handover: Handover Notification

Power Saving Mode: Enter Idle mode

Reset: Reset SS

SS Info: Provide SS information

DSX: Dynamic Service management. Service flowadd/change/delete. Both BS and MS initiated

Authentication: Authentication management

Beceem Connection Manager Engine

Advanced connection detection and

connection engine Allows the Customer to design a

separate GUI that has WiMAX profilesthat will be automatically detected

User can then be either automaticallyconnected or can be prompted toconnect when the network is located

Once connected, the user can thenbe automatically authenticated.Beceem will also provide EAPsupplicant

Integrated set of diagnostic andreporting capabilities

Connection Manager Feature Summary

Purpose

Intended as a teaching tool for Beceem customers software developers Illustrates use of Beceem WiMAX API library for connection management,

authentication, and information reporting

Provides source code for all Beceem-developed components

Software characteristics Connection Manager communicates with the WiMAX Adapter exclusively via

the WiMAX API library Client-Server architecture allows use of different user interfaces

Both local and remote operation supported

CLI Client, Server, and EAP Supplicant written in C

Installation Windows: Connection Manager and EAP Supplicant installers provided

Linux and OS X: Build script, make files, and source code provided

Documentation Installation guides, user manual, programmers manual

Client Server Architecture

Server listens on the localhost interface (127.0.0.1)

One or more clients run on the same computer as theconnection manager server

Server runs on the Host processor that controls the BeceemWiMAX device

When multiple clients control the server, control conflicts canarise

CLI Client Features

Runs on Linux, Android, OS X, Windows XP/Vista/Win 7

Run modes Execute single command and exit, or

Open an interactive session for running multiple commands

Scriptable with Python, Perl, Visual Basic Script, or any other scripting language

Web page via CGI script

Batch file

Input redirection using list of commands

Service auto-start (Windows only) Client can start the Beceem CM Service if the server is not running

Command line switch specifies the servers config file path

Command line switches Interactive run mode

Server IP address and port
