4. Point to Point
Pros
Dedicated connection
Highest bandwidth for backhaul
Cons
Does not scale; no flexibility
Single point of failure
4
5. Point to Multi-Point
Pros
Simplicity of design
Cost effective when tall assets are available
Cons
Limited scalability: bandwidth divided by # of subscribers
LOS required to each subscriber unit
Base station creates a single point of failure
5
6. Multi-Point to Multi-Point (Mesh)
Pros
Reach & scalability with multi-hop connections
Flexibility – can be deployed a PtP, PtMP or mesh
Distributed intelligence vs command-and-control approach of PtMP
Cons
Variable performance from different vendors
More complex design vs PtP or PtMP

17. Key Requirements for Mobile Video
Fixed and/or mobile infrastructure
High throughput
Low latency < 1.5 ms per hop
Low packet jitter (variation in latency)
Zero packet loss & end-to-end QoS
Specialized infrastructure required
APs not suitable for real-time, high-bandwidth mobile video
surveillance
