Point to PointPoint to Point
Advantages Proven Technology High Capacity Lower Up-front Investment
Disadvantages Dedicated bandwidth to a single location . Star configuration: emulates PMP, but antenna
placement becomes an issue and business case fails after 8-10 links
Ring configuration: emulates a fiber ring. Adding new nodes takes 3 building climbs

Advantages Real-time allocation of bandwidth based on user
demand Oversubscribe equipment and frequency = Lower
CapEx Central base stations aggregates & concentrates
traffic from many subscribers. Smaller hub roof space used No need for external concentration device Roof climbs = # subscribers + 1
# of subscribers +1 network elements
Disadvantages Higher upfront cost than PTP Bandwidth to a single building < 45Mbps
