What is wifi scan interval?

I know it's kind of a silly question, but I haven't found an actual answer anywhere. Is it just the interval that the wifi scans at to find new networks?

silly questions are fine, if you can't find an answer on your own.
Yes, wifi scan interval is just how often it checks for networks when you aren't hooked to one.

So since I keep wifi off all the time unless I'm at home or connecting to a hotspot, will changing the interval really have much of an effect for me?

No, since it wont be scanning anyway.

That's what I thought, just making sure.

Just out of curiosity, can you change that?

Because sometimes I forget to turn if off when I leave home, and I don't want it to keep scanning for hotspots each 10 seconds, I'd like the scan to be manual.

There are some apps that can change it or you can just edit the value in the build.prop. I'm not sure you can actually disable it though. If you have a problem with forgetting, you may want to consider downloading a widget to turn it on/off.

There's an app called Unlock With WiFi, which disables your pin lock when you're connected to your home Wireless network. It will also automatically switch WiFi off when you've not been in range/connected to your home network for 45 seconds (you can change this value yourself).

It did have an app that worked in tandem with it called Auto Wifi Enabler which did the opposite, turned WiFi on when you got in range of your wireless network though. As it based the location off Cell Towers, I found it wildly inaccurate. Looks to have been removed from the market though.

Tasker could probably switch WiFi on and off automatically though.

I think ICS should have this kind of improvement.

Sometimes I forget turning off the wifi while leaving home, and only do it some hours later... Meanwhile, I have my battery drained for useless network scanning.

There should be an option to completely turn off wifi after X unsuccessful attempts to connect to a hotspot.

Confirmed. The Tasker Wiki on the app's web site contains several examples of how to do it.

I set wifi to scan every 180 seconds using my build.prop. I do this to all my roms. I never turn wifi off. I can go 15+hrs with 3hrs+ of the display being on. What else can you ask for

I got this "Wifi power saver" from market today, and I won't need to worry about Wifi anymore.

When I leave home/work/college, it will be shut down automatically.

Can you tell me what the value is in build.prop that I should be looking for?
