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 • • • • • Enhanced system maintenance Enhanced subscriber management RADIUS compatible OAM support (SNMP managed) Alarming NMS Workstation Internet Router Bandwidth Manager Ether Switch CAP Links 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 Link to . NAP/NMS Switch CCU UPS CCU CCU CCU RF Switch Matrix 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 Network Management 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 Network Management 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
