That is Network Location and it is only going to be slightly more accurate than Cell near (and it requires you to have a data connection, unlike Cell Near). I found that i had to go to 2-3 KM range in order to get it to activate reliably whenever I'm at the location. There is NO WAY that a network location is going to be as accurate as <50m
Cell Near will be a list of Cell towers, and Wifi near will have your home Wifi information.
Cell Near is going to have a WIIIIIIIIIIIIIIIIDE range that it activates in, Basically if your phone is connected to any of the cell towers on the list, Cell near will activate.
Wifi Near is going to be more accurate. Like i said before it will toggle wifi (if set) and check the nearby wifi networks.
Combining the two means that once you are in your neighborhood, Cell near activates and only then does Wifi Near start toggling Wifi and checking networks. When you make it home it then sees the network and activates bringing the profile active and running the enter tasks.
The issue you may see is that while this profile will work pretty well when you ARRIVE at the location there may be significant delay in registering that you have LEFT said location.
Wifi Near can take up to 240 seconds (4 minutes) after you've left the location to deactivate, if you've left the wifi scanning at the default of 120 seconds. In order to deactivate a Wifi Near context, Tasker has to have 2 consecutive scans without seeing any of the specified networks.
This to prevent profiles from constantly being activated and deactivated while on the edge of a Wifi network's range where getting scans without seeing the network every so often is common.
So assuming that for the frist 5 minutes after you've left the house you are still in Cell Near Range (a single tower's range is measured in Miles so this isn't uncommon) it could take as long as ~5 minutes for Tasker to register that you've left the house.
If you have some way of registering that you are in the car (Built-in Bluetooth, car dock, or you bought one of
these like i did) you can setup a car profile and then add an extra "Profile Not Active" context to your location profile, then it won't even START looking for any of the location contexts until your car profile goes inactive, which will usually be in your driveway, then Cell Near immediately activates, and Wifi Near begins to scan and immediately sees the home Wifi so the Location profile will activate almost Immediately after you shut off the car (or remove the phone from the dock).
And when you go to leave your car profile does go active and immediately deactivate the location profile triggering the exit tasks on the location profile.
Hope this helps.
