LMS2000 SYSTEM

Introduction

• World’s 1st truly integrated wireless Internet system

• Provides Wireless Internet access• 11 Mbps raw data rates using DSSS in the

2.4 GHz ISM band• Fixed Wireless Access data system • Target multiple small to large size offices• Services include:

• email• WEB browsing• FTP

LMS2000 Main Blocks

• End User Modem (EUM)• Communications Access Point (CAP)• Network Access Point (NAP)

• system management and access to the Internet and system wide services

• Backhaul• Infrastructure components

• antennae, cable, mounts

LMS2000 Configuration

The NAP

• Data network infrastructure• NMS

More NAP

• Supports 7 CAPS• Half height indoor free-standing 19”

equipment cabinet• Equipment includes:

• High speed CISCO router • 100BaseT CISCO Ethernet switch• UPS

• NMS Workstation

CISCO Router

• Directional gateway between the LMS2000 network and the Internet

• SNMP Managed• GUI configured

CISCO Ethernet Switch

• Gateway that moves data between the NAP and the CAP

• Enables connecting up to seven CAPs to one NAP Ethernet switch via 10/100 BaseT compatible Backhaul.

• Serves as the system connection point for the NMS workstation.

• SNMP managed• GUI configured

Bandwidth Management• EUMs transmit data at the max rate which creates

competition for bandwidth • Prevents inconsistent data transmission and

overloading the system• Provides for the allocation of data traffic rates to and

from the EUM• Provided by the router for smaller systems, dedicated

Bandwidth Network Manager (BWM) in large systems• NMS application allocates service levels to each EUM• Allows differentiated service levels generating

additional revenue• SNMP managed• GUI configured

NAP UPS• An alarm will indicate power shutdown which

allows operator a minimum of 10 minutes to perform a graceful shutdown.

• Continuous protection from power surges, spikes, or sags on the main power lines.

• SNMP managed• GUI configured

NMS Workstation

• Personal computer equipped with a printer, keyboard, mouse, backup tape drive, and a uninterruptible power supply (UPS) with APS PowerChute PLUS software for monitoring system power levels.

• The NMS Workstation contains the software for managing the LMS2000 system.

NMS Software• Microsoft Windows NT 4.0 Workstation (with Service Pack 6a)

• WaveRider LMS Network Management System

• Microsoft SQL Server

• Vircom VOP RADIUS– server controls the logon and authentication access for the EUMs.

Each EUM has a coded ID/password combination that RADIUS will use to recognize the modem.

• Castlerock SNMPc Server

• Tardis Timeserver– provides time synchronization between the Internet and the CAP

and NAP hardware

• APS PowerChute PLUS

• Veritas Backup Exec with Microsoft SQL Agent

• Mirrored Hard Drive Disc System RAID 2

The CAP

• Provides the path for the NMS to the EUMs• Provides the central radio access point for EUMs • Provides a path for Internet data to travel between the EUM

and the NAP for routing to the Internet.• Up to 3 active channel units - hot swappable• Extra channel unit and switch matrix for redundancy• UPS• 10/100 BaseT connection for backhaul L ink to

More CAP

• 3 CAP channel units (CCU)• Cisco Ethernet switch• Uninterruptible power supply (UPS) • Additional channel unit and RF switch matrix for

channel unit redundancy (option)• Additional hardware supporting the CAP RF

subsystem, including antennae, antennae mount, lightning arrestors, cabling, and connectors

• Backhaul equipment not contained in the CAP cabinet

CCU

• Based on proprietary WaveRider wireless and IP technology

• Wired-to-wireless conversion• 11 Mbps wireless data rate• IP router function• Up to 30 EUM’s• FCC/IC approved• SNMP managed• GUI configured

CAP CISCO Ethernet Switch• Gateway that moves data between the CCUs and the

backhaul interface • Collects data from multiple CCUs and directs all the

data into a single stream (aggregates) then sends the streamed data to the external backhaul

• In the NAP-CAP direction the Ethernet switch collects data from the backhaul and fans it out to multiple CCUs

• GUI configured

CAP UPS

• An alarm will indicate power shutdown which allows operator a minimum of 10 minutes to perform a graceful shutdown.

• Continuous protection from power surges, spikes, or sags on the main power lines.

• SNMP managed• GUI configured

Backhaul

• Determined by the configured size of the CAP, the available backhaul infrastructure and spectrum in the service area, and the distance between the CAP and the NAP

• Consult WaveRider System Engineer for determining

• Should be SNMP managed• Fast as the slowest link

EUM

• Based on WaveRider proprietary wireless and IP technology

• IP router function• FCC/IC approved• SNMP managed• GUI configured

Redundancy Features

Need

• System reliability is measured by the availability of the system to the subscribers.

• Down time is a critical factor in maintaining customer satisfaction and a solid revenue flow.

Design Features

• Industry leading Cisco routers & switches to ensure long term reliability and industry compatibility

• Key system elements (NAP, NMS, CAP) protected from power outages by dedicated UPS units

• Radio modules based on field proven 802.11 ISM band integrated components and WaveRider modem technology

Design Features

• Policy-based bandwidth management ensures disciplined control of all access to the valuable system bandwidth resources

• Back-up CAP channel unit, CCU, constantly monitors active channel units and automatically replaces a defective channel

Centralized NetworkManagement System

• GUI based network configuration with rule checking

• Automatic database synchronization• RAID 2 data storage protects against disc

failure• Database backup utility• RFSM GPIO for External Alarms

Centralized NetworkManagement System

• Automated system monitoring and messaging to provide warnings re: approaching overload conditions, performance degradation or failures

• Automatic monitoring of hardware configuration and software version

• Remote downloading of new/upgraded software throughout the network
