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?

Network Hops – Related to Mesh Networks

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

Hopping allows us to extend the network rangeIn this example we are showing a Network with 5 hopsIf design range is 65 feet we can push the network out 325 feet from the coordinator
