  2. Presentation Outline • Company Overview • Service Provider Challenges • Progressive Implementation Concept • Real World Network Examples Employing Various Technologies • Wireless Gigabit Ethernet Advent • Conclusions

  3. Our Business Metropolitan Broadband Wireless Infrastructure Broadband Transport and Access Networks for Internet, Voice, Data and Video for Service Providers & Enterprises: ILECs, CLECs, ISPs, Private Networks, Mobile Telephony/Data

  4. Company At-A-Glance • Established in 1996 • Product Launch in 1998 • IPO in August 2000, NASDAQ - CRNT • >300 Employees • Headquarters: Tel Aviv, Israel • New Jersey, USA • Birmingham, UK • Offices: 4 in USA, Mexico, Germany, France, Spain • Customers: 54 in 23 Countries • OEMs: Nortel, Siemens, Lucent

  5. Next Generation InfrastructureWhere We Fit Residential/SOHO IXC/Internet Transport MetropolitanSONET, IP, or ATM ring MDU Mobile Medium/large business From Within the Core to the Curb: High Capacity Infrastructure & Access

  6. 25k – 50k 50k – 180k >180k Last/First Mile Options 800,000 commercial buildings in the US: only 3 – 4% of those have fiber Approximate Building Size (Sq. Ft.) Mobile Wireless Broadband(128k – 10Mbps) Point-to-Point Broadband Wireless PMP DSL/Cable High Capacity (>100Mbps) High-Capacity Connectivity Fiber Source: CSFB Research

  7. Next Generation Networks • Broadband 128 Kbps – 10 Mbps • xDSL Asymmetrical • Cable Low deployments in business areas • WLL Shared E1/ T1 • PMP Shared sector capacity • High Capacity >100 Mbps+ • Fiber Expensive, cumbersome to deploy $150,000 per mile construction cost • Wireless Immediate – “same day service” Much lower installed cost per bit Quick revenue generation Easy to redeploy

  8. Challenge: Connect a Variety of Applications to a Variety of Legacy & Emerging NextGen Networks Internet Data Video Voice Applications Networks IP ? ? SONET/SDH PSTN SONET/SDH ? ? ATM Protocol Converters Add/Drop Muxes Media Translators Aggregation Devices, etc. = ? Cost & Space
