● WiFi
● Bluetooth
Multiple Standards – We will focus on four
● EnOcean
● 6LoWPAN
● Wi-Fi
● DASH7
● ONE-NET
● ZigBee

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..

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
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
