## Emergence
**Emerges from:** [device](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-device.tool), [phone](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-phone.electrical), [message](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-message.information), [power](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-power.energy), [send](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-send.communication), [use](https://emergencemachine.com/tools/lexicon/what-is-the-meaning-of-use.application)

**Through:** the device uses electrical power to convert the message into signals that the phone transmits

**Novel properties:**
- transmitted message in signal form
- remote synchronous delivery
- analog encoding of information
