Sending a Number Over Wifi: Energy Requirements

AI Thread Summary
The energy required to send a 1-3 digit number over WiFi depends on several factors, including the device, antenna, protocol, and environmental noise. Establishing a connection typically consumes more energy than the actual transmission of the short number. Bluetooth Low Energy (BLE) is suggested as a more efficient alternative for such short transmissions. Maintaining a connection continuously uses power, with periodic data transmission only slightly increasing overall energy consumption. Understanding these dynamics is crucial for optimizing energy use in the project.

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.

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

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

Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
