Sending a Number Over Wifi: Energy Requirements

[akahn430]

I'm currently working on a project involving Wifi transmission. The device needs to send a 1-3 digit number to a computer/phone that is 5-15 feet away. Approximately how much energy will this take to send one number?

Thank you!

Depends on your device, its antenna, how much control you have over the device, the protocol, the noise in the environment and various other things.
If you use conventional protocols, establishing the connection will need much more energy than sending the short digit.

You can look at the Bluetooth low energy device for typical energy requirements.

which is what I suggested to him on another forum

tried to get him to understand that as long as the link is connected power is being used and the periodic transmission of data
just slightly increases the power usage.Dave
