Where we are with Wireless?Mobile devices have changed our perception of Wireless
● Cellular 3G : 4G LTE● WiFi● Bluetooth
Multiple Standards – We will focus on four● EnOcean● 6LoWPAN● Wi-Fi● DASH7● ONE-NET● ZigBee ● Wibree● WirelessHART● ISA100.11a● OCARI● Z-Wave● MiWi

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
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
