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

• Access and Corporate Connectivity
• Where links originate from a common hub site
• RADWIN 2000 w/ HSS supports high capacity
  connectivity

• 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

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.

Lower rate streams
Streams merged into one signal
High rate signal
TX
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
