Brining Network Intelligence to Broadband Wireless

1
The Future of Video Surveillance over Wireless
Mesh
2
Why Wireless for Video Backhaul?

• The only choice for mobile surveillance

3
Why Wireless for Video Backhaul?

• Low cost, no leased-line or cabling cost

Wiring often the most expensive part of networks
4
Why Wireless for Video Backhaul?

• Rapid Deployment

No costly and time consuming trenching required
5
Why Wireless for Video Backhaul?

• Flexibility

Emergency response, temporary sites, changing
network needs

Why Wireless Mesh for Video Backhaul?

• All the above plus
• Extended coverage
• Even lower cost
• Self-forming for rapid deployment
• Self-healing for reliability
• Overcome line-of-sight issues

Traditional Mesh Video Challenges

• Unreliable, limited capacity
• Rapid degradation of bandwidth over multiple hops

• Poor video quality
• Susceptible to interference and noise
• Packet losses cause image freezing, mosaic, etc.

• Poor mobile video support
• Slow handoff
• Cant adapt to speed changes

• Traditional Mesh Tree
  Architecture
• All traffic goes through a gateway
• Non-optimal routes, latency
• Single point of failure

14
Solving the Capacity Challenge

• Azaleas routed multi-radio multi-channel
  architecture delivers superior capacity with
  minimal degradation over multi-hops

15
Solving the Capacity Challenge

• With typical single backhaul radio networks, due
  to crippling self interference, user throughput
  and critical video quality degrades dramatically
  with just a few hops

16
Solving the Capacity Challenge

• Azaleas routed multi-radio, multi-channel
  architecture and AVT ensures virtually no image
  quality degradation over multiple hops

• Scalable and most cost-effective

17
Industry Leading Capacity
18
Higher, Faster, Stronger

• Higher user throughput (up to 74 Mbps) with
  SuperAG available today
• Longer distance (up to 20Mbps over 10 miles) with
  MAC protocol optimization and radio bundling
  available today
• Even higher user throughput (gt 100Mbps) with
  802.11n/MIMO backhaul technology in the near
  future

19
Video Quality Challenge

• Higher packet loss and jitter for wireless due to
  interference and noise bad for video quality

• Not all video frames are born equal

• Video quality becomes really poor (freezes) if
  important frames are lost

20
Solving Video Quality Challenges With AVT

• Patent-pending Azalea AVT (Active Video
  Transmission )
• Deep packet inspection
• Adaptive jitter removal
• In-network retransmission
• Protocol optimization

Seeing is believing

Optimized Mesh Multicasting

• Mesh Multicasting is challenging
• Dynamic noisy wireless environment
• Multicast sender can only apply lowest rate
• No ACK for multicast traffic ? high packet loss

• Azalea patent-pending mesh multicasting
• Optimized Layer-3 mesh multicasting routing for
  backhaul
• Optimized mesh multicast transport for access
• Reliable and efficient multicasting support
• Compatible with existing Wi-Fi clients
