Bluetooth long range and low power.

We have several sensors which we require to send to a Cell phone.  As Cell phones currently do not support ZigBee or BLE we have few options.

 

Can Bluetooth and ZigBee co-exist within the same chipset and or device?

Can we create a ZigBee to Bluetooth media converter to cover the longer range?

Do you see Bluetooth extending it’s range to that similar to ZigBee?

How can we achieve 3 months battery life from 2*AAA cells using Bluetooth without Audio?

    Hi Kim,

    You are asking some good questions here, I will try to answer some of them.

    I'm not personally familar with what co-existence features are included in various ZigBee implementation, you may want to ask this question in the ZigBee forums.

    Bluetooth would not be able to do the mesh networking you can do with ZigBee, but the link budget achievable with Bluetooth is quite close to that possible with ZigBee, so for a single link, you could have similar range.

    To get 3 months live on 2'AAA, you need an average current of around 0.5 mA. Whether this is possible or not will depend on what the RF duty cycle is in your application.

    Best regards,

    Karl
