Difference between mica & micaz

Can Mica be used for wireless sensor networks

Use of Zigbee,, is it neccessary?

What can Micaz do that Mica can’t?

What is the usage of the Mica2 OEM product

Price list for the UK market?

if I incorporate in my product what would the requirements for licencing be?

Aim

1. Want to start Developing own apps first

2. If integrating into other apps which product best to use

Key requirements to achieve

• Reliability – 99.99%
• Wireless – Multi year battery life
• Enterprise Integration – IP and industry protocols
• Flexibility – Application optimization
• Deployability – Network Management

Nodes Collect sensor information – light / heat / weight / changes in environment

Within a time frame send data to a remote sink / sensing device

Sensing device forwards information to Gateway

Gateway uses ethernet / wireless to send data to server

Data on server is recorded and sent to application / device for modification / analysis

Predicted Unit Sales – 100 – 120 Million units

Top 5 requirements

• Reliability – 99.99%
• Wireless – Multi year battery life
