7. Points to consider when Choosing a Technology
Security
What types are available with each technology
Do they meet the needs of my organization?
Installation
Do I need special tools?
Do I need special labor?
What are my limitations for deployment?
Point to Point
Master Unit broadcasts to all others
Distance and Obstructions critical
Mesh
Master Unit broadcasts
Some units repeat to extend range
Requires a good understanding of device ranges
Hopping
Allows extension of networks over longer ranges
Need to be aware of hop limitations 3, 5 etc..

8. Points to consider when Choosing a Technology
Self Healing
What happens when a device looses power
Power
What will my power source be?
Battery life
How often do I have to change batteries?
Who do I purchase batteries from?
Range
what are the distance restrictions?
Bandwidth
Will it interfere with my current networks
Is network speed an issue
Cost
How does the cost compare with competitive technologies?
Interoperability
is it open and do I care?

10. Mesh Topology
LAN

11. Network Hops – Related to Mesh Networks
Hopping allows us to extend the network range
In this example we are showing a Network with 5 hops
If design range is 65 feet we can push the network out 325 feet from the coordinator
Mesh Networks have limitations
> Number of allowed Hops
> Number of addresses a node can give out
> Amount of resources (storage) available at the “coordinator”
> More devices slower network speed
