As a guy who has investigated this at a technical level...
- ANT+ isn't strong enough.
- Wifi is odd.
- Bluetooth LE isn't powerful enough and is finicky
- Full-strength Bluetooth (not LE (Low Energy)) might work, but eats a lot of battery power and is still sorta finicky.
There is no easy solution, otherwise you'd see the major manufacturers producing something.
To make the right system, it will have to be built from the ground up, not simply riding the coat tail of another technology.
The limitations are basically the radio transceiver within mobile phones and cycling head units...and whatever device will receive the data in the infield.
The ground-up design starts with using a protocol that isn't ANT+, Bluetooth, or Wifi.. Anything using one of those 3 will be lacking in some way.
