Sending a Number Over Wifi: Energy Requirements

Click For Summary

Discussion Overview

The discussion centers around the energy requirements for transmitting a 1-3 digit number over Wifi to a nearby device, exploring various factors that influence energy consumption in wireless communication.

Discussion Character

  • Exploratory
  • Technical explanation

Main Points Raised

  • One participant notes that energy consumption depends on multiple factors including the device, antenna, control over the device, protocol used, and environmental noise.
  • Another participant mentions that conventional protocols may require significantly more energy to establish a connection than to send the actual data.
  • A suggestion is made to refer to Bluetooth low energy devices for typical energy requirements, with a link provided for further information.
  • A later reply reiterates the suggestion about Bluetooth low energy, emphasizing that power is consumed as long as the link is active, with periodic data transmission only slightly increasing power usage.

Areas of Agreement / Disagreement

Participants express varying views on the factors affecting energy consumption, and no consensus is reached regarding specific energy requirements for the transmission task.

Contextual Notes

Participants highlight the dependence on specific device characteristics and environmental conditions, which may not be fully defined in the discussion.

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!

Austin

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.

which is what I suggested to him on another forum :smile:

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
