RADWIN 2000 Radio Series Carrier-Class, High-Capacity Sub-6GHz Backhaul Solutions The RADWIN 2000 Radio Series delivers high capacity, extended range and carrier-class performance for IP and TDM networks. RADWIN 2000 provides native TDM and Ethernet over a single wireless link and incorporates advanced MIMO and OFDM technologies. The flexible multi-band radio delivers 2.3 2.4GHz and 4.9 5.9GHz frequencies on a single platform. RADWIN 2000 is the solution of choice for carriers looking for affordable backhaul solutions. With ever increasing demand for broadband services, carriers require high-capacity, cost-effective backhaul solutions. RADWIN 2000 enables carriers to accommodate capacity growth and maintain profitability through unparalleled price and excellent performance. The high-capacity radio system provides 100 Mbps net throughput (50 Mbps full duplex), with a flexible combination of Ethernet and up to 16 E1/T1 interfaces and a range of up to 120 km/75 miles. To deliver optimal performance and unmatched robustness in all environments, RADWIN 2000 deploys advanced MIMO and OFDM technologies, ogether with built-in Diversity and RADWINs proprietary air interface, built to deliver native TDM and high-quality Ethernet in sub-6GHz bands. The flexible multi-band radio supports multiple frequency bands over a single platform, granting utmost field flexibility and simple stock management. Radwin 2000 Unique Technology Multiple Point to Point: High Capacity Multiple Locations RADWIN's breakthrough WinLink 1000 Multiple Point-to-Point architecture allows service providers and ISPs to provide multiple end-users with carrier class services (TDM and/or Ethernet) and dedicated bandwidth from one Hub site. The Hub site includes RADWIN's unique Hub Site Synchronization (HSS) technology which synchronizes the transmission of up to 10 collocated WinLink 1000 radios - thus eliminating mutual interference commonly experienced with collocated TDD radios. It also includes RADWIN's Base Distribution Unit (BDU), a single indoor device that connects up to 8 collocated radios, while providing uplink traffic aggregation (TDM and/or Ethernet) and full layer-2 switching capabilities.

• Deliver dedicated bandwidth per each end-user
• No degradation in network performance as more users join the network
• Directional antennas less vulnerable to interferences
• Provide combination of TDM + Ethernet services
• Low entry costs; Scalability in network growth
• Easy planning no need for radio planning

MIMO Technology Increased range and reliability:

• The Ethernet data stream is split into two lower rate chains.
• These chains can be transmitted in lower rates, achieving longer ranges and higher reliability
• The streams arrive at the receivers in different quality. MIMO chooses the best stream available
• Paths in poor quality are thus eliminated and availability increased

Increased capacity and improved spectral efficiency

• Each radio (chain) carries the full OFDM channel capacity
• Both radios use the same 20MHz channel
• Thus doubled capacity per the same channel bandwidth
