Cellular Backhaul
11
The RADWIN Backhaul Advantage High-Capacity Wireless Sub-6GHz Solution Low CAPEX Very competitive price Low OPEX Easy to install and maintain (1 person, 1 hour) Fewer towers, fewer links Instantly Deployable – Immediate Revenue License free – no license fees, no trenching
12
The RADWIN Backhaul Advantage (cont.) One Solution, One Link, One Platform Robust & Reliable Operates in all environments & terrains Industry-leading MIMO, OFDM & Diversity technologies Field-proven air interface for optimal performance Monitored Hot Standby 1+1 Support – backup link ensures 24x7 service continuity and revenue flow Flexible Multi-band radio – one platform, multiple frequency bands Complies with international regulations Native TDM & Ethernet in one solution Seamless migration from TDM to IP Can be deployed in various topologies & configurations (PtP & Multiple Point-to-Point)
13
Multiple Point to Point w/ HSS (Hub Site Synchronization) RADWIN 2000 can be deployed in unique Multiple Point-to-Point configuration Dedicated bandwidth to as many as 16 dispersed sites Hub Site Synchronization (HSS) unit synchronizes transmission between collocated radios Synchronizes Tx and Rx timing for all units in hub site Eliminates collocation TDD interference HSS between RADWIN 2000 radios WinLink 1000 radios RADWIN 2000 and WinLink 1000 radios
14
HSS Applications Backhaul HSS is needed in installations where RADWIN 2000 is the backhaul for lower capacity access links The backhaul link can be synchronized to the access links to mitigate potential interference Access and Corporate Connectivity Where links originate from a common hub site RADWIN 2000 w/ HSS supports high capacity connectivity
15
Dealing with Interference Multi-band radio Automatic Adaptive Rate Automatic Channel Selection (ACS) Automatic Repeat Request Forward Error Correction Configurable Jitter Buffer Spectrum Viewer Directional Antennas MIMO OFDM based air-interface, enabling nLOS deployments and achieves best spectral efficiency Spectrum Viewer
16
Multi band radio Multi band radio supports multiple frequencies on same platform – ensures maximum transmission resiliency Utmost field flexibility
17
Automatic Adaptive Rate RADWIN 2000 changes air interface rate and modulation dynamically, depending on radio link conditions Benefits: Maximization of Ethernet throughput Enhanced robustness Better performance in interference
18
Automatic Channel Selection (ACS) Automatic selection of “best-quality” channel for transmission Enhanced robustness and higher performance
19
Automatic Repeat Request (ARQ) Patented mechanism that ensures super-fast retransmission of errant data Repeat transmission is initiated without having to wait for a request from the remote unit The system minimizes either the latency or the error rate to optimize performance for the type of services being delivered
20
Forward Error Correction (FEC) FEC detects and corrects errors in the receiver Ensures fast, robust and error-free communications
21
Jitter Buffer By configuring the Jitter Buffer, the receiver jitter buffer for each site can be enlarged, thereby increasing resistance to interference Decreasing the Jitter Buffer decreases system delay Jitter Buffer can be configured between 2.1 and 16.0 milliseconds
22
Spectrum Viewer Spectrum Viewer is an RF survey tool that simplifies link planning & installation by graphically displaying “cleanest” channel The tool provides the following information: Spectral measurement of two antennas per site Spectral power measurements in 5MHz channel resolution Indication of radar-free channels (for DFS bands) Indication of bands selected for ACS
23
Spatial Multiplexing MIMO MIMO = Multiple Input Multiple Output A high rate signal is split into multiple lower rate streams and each stream is transmitted from a different transmit antenna in the same frequency channel. Streams merged into one signal TX Lower rate streams High rate signal RX
24
Diversity Antenna diversity Uses two antennas to improve the quality and reliability of the link Each antenna experiences a different interference environment The system chooses the best received signal providing enhanced robustness Antenna diversity requires antenna separation, possible by two methods: Polarization Diversity - combines a pair of antennas with orthogonal polarizations Spatial Diversity - employs antennas that are physically separated from one another
25
Diversity vs. MIMO with RADWIN 2000 Diversity Capacity 25 Mbps MIMO Capacity 50 Mbps
26
Monitored Hot Standby 1+1 Providing backup to TDM services in the event of: Equipment failure Loss of air interface MHS 1+1 ensures high network availability & revenue flow Automatic switchover from the Primary link to the Secondary link in less than 50 msec Automatic restore to primary link as soon as it becomes available Backup for up to 16 TDM services for RADWIN 2000 & 4 TDM services for WinLink 1000 Affordable SLA can be offered by protecting part of the RADWIN 2000 trunks with WinLink 1000
27
Monitored Hot Standby 1+1 Architecture Primary & Secondary links can transmit on same or different frequency channels RADWIN 2000 & WinLink 1000 links can be used interchangeably Using a primary link and a secondary link: Two RADWIN 2000 links A RADWIN 2000 link and a WinLink 1000 link with new IDU-C Two WinLink 1000 links with new IDU-C (single dual-pole antenna can be used) Simple architecture & easy installation
28
RADWIN Network Management System (RNMS) Manage up to 10,000 RADWIN links from one location (NOC) Proactive real-time monitoring using performance graphs, trend reports and threshold alarms Complete visibility & control over RADWIN-based network Interface to any SNMPc device Auto-discovery feature – discovers all RADWIN links in the network automatically, within minutes Available in Enterprise & Platinum packages
