Does N1 share gps over wifi tether?

I got an iPad the other day, and have been using the tethering ability of N1 with CM6.1rc1 while at work. I have the basic wifi iPad,that does not have gps built into it, but it is able to pull location data from wifi. While on my homes wifi, google maps shows my location about 300 Feet from my actual location, but while at work using my phone for wifi, it's much more accurate, only off by about 30 feet or so. So does my N1 share the gps location over the wifi when tethering is turned on?

Nope... Just means that the location services being used by the ipad know what wifi is near your office better...

My Guess is that its based on your external IP. Something like this http://www.ip2location.com/free.asp

Google actually records the location of your wifi network, when you use things like latitude.
When I moved from Australia back to New Zealand for about a month whenever I was connected to my home wifi router, google said my location was in australia (because that was the same router I was using in australia).
Even though I had changed the ssid etc, I still had to wait for google's servers to realise I had moved. So I guess they record the location along with the mac address for the router.

Just gave that a try, and I'm guessing that's not it. It shows my location 10 or 15 miles away from my actual location.

Is it able to pull location data from wifi networks that are not even visible to me?

I used to tether my iPod Touch to my Androids before it was stolen. Same idea, I think it just looks for all the wi-fi MAC addresses nearby and triangulates a probable position. If the network you're connected to is not in its database (and inevitably, the MAC address of a tethering phone won't be), then it just sniffs out all the other surrounding wi-fi networks. So whatever networks are visible from your office, they are already in the Skyhook database.

Maps location

I try to find location and it says enable location, but you cant in tnt lite settings I'm pretty sure I can load regular android settings and enable it but have yet to do so...has anyone tried it?

There is no GPS in the unit so it couldn't find location even if you enabled it.

u can find location with wifi...

You need GPS or aGPS which the device has neither.
aGPS can use cell towers and WiFi points to help triangulate your location.

It would use router as location like a computer

The Original Poster is asking how to enable WiFi based location.
The option does not exist in the TnT settings, but it does in other devices.
It works fine on my cheap Augen Gentouch, which definitely does not have GPS.
You also do not need a cellular radio in the device.
For those that do not understand how this works, it has been in the news recently how Google drives around logging WiFi access points. They also have GPS in the car. From this they have created a data base of where your AP is located.
If you are connected to the internet via Wifi router <router name /MAC>, then you must be geographically near that router. Assuming that the location of that router/internet route has not changed since they drove by, then your location is known down to the range of a typical Wifi access point (within about 300 ft Max, assuming a network with a single AP.).

Exactly...I need a vanilla settings file I can push to enable that setting

How does google maps know my location?

Does anyone know how Google Maps knows my location on the NC? I thought the NC did not have a GPS. Perhaps, Maps could use my IP address, but it seems really accurate, within 10 meters.

Google collected wifi access point names and locations while driving around to build Streetview. If your wifi is turned on, they can use your list of visible hotspots to approximate your location.

Do you see that white unmarked cargo van parked down the street from your house?

This works with both Wi-Fi Tether and tethered with Barnacle. That would rule out using Wi-Fi data as a locator. I did however, use the locate button on g'maps using the LAN connection before I tried it with wireless tether. Maybe its showing a cached location.
I'll test the location feature with a wirless tether somewhere else tomorrow to check this.

No, it does not rule it out.
Is your tethered hotspot the ONLY access point in range? The location via wifi is NOT based on the network you are connected to, it is based on comparing the relative signal strengths of ALL visible access points. If there are three visible WAPs with known locations, it's fairly trivial to plot your position with high precision. Even just one or two visible access points can yield a pretty accurate location.

Determining location based on other access points makes sense. I see 4 or 5 access points quite often. Thanks!

No its not the only access point. The area is saturated with 12-15 different WAP at any time. You are probably right. I know a spot nearby which shows no access points, will try out g'maps with a Wi-Fi tether there sometime this week.

If Wifi is on, it'll do the Wifi location stuff. It goes off ESSID, ie: router MAC address, so even if all of your neighbors are stupidly all using "linksys" as their SSID, they're all unique regardless.
I've only had it find me at the house, so far nowhere else, but it's handy that it does have a starting reference when I'm using it at home.
There is also network location lookups it COULD do based on your IP address, but I'm not sure how those services work... i'd assume it has to ask a service "Where is my IP located?" and if it's behind a NAT it won't know obviously. It could however use the outgoing connection (your internet connection), although in that case it would be potentially many miles off if it worked, certainly not accurate.
When it locates me at my house it shows me right in my front yard.

This technology is awesome. But, it only seems to work with stock rooted. I haven't been able to get nookie Froyo or HC to determine my location via this method.

Chromecast on public wifi networks?

I bought a Chromecast yesterday, and I'm going to be headed off to college in a few weeks, and I am really hoping Chromecast has some protection against random intruders. Because I'm bringing a small HDTV with me, and I'll be using my school's public wifi network. Anyone else have any thoughts?

Does your dorm/apartment room have a wired ethernet connection as well? You could probably buy a cheap router and set a small private wireless lan.
I never lived in the dorms when I went to school but my ex girlfriend did and this is what I did for her.

Ah! I never thought of this! While this will definitely work for me, I worry about other consumers who buy Chromecast who won't have access to ethernet/a router

There is no protection or security unfortunately - this is something that Google really needs to address.

Yeah, even if it's just a 3 or 4 digit pin, i'd be perfectly fine with that

I will have this device in a dorm room at college, on the school's wifi network
Anyone with the Chromecast app and is near me could hijack my TV

Ahh, I see.
I thought you were worried about hacking through the GCast to your phone or comp.
I haven't gotten mine yet but I would assume it works through google services and you would sign in with your google account or a pin would pop up on the TV to link the two.

I really hope that Google does an update soon that adds some kind of basic security. As others have said, a simple four digit code that is displayed on the TV that you need to type into your device would be fine.

I wholeheartedly agree

It would work as long as
1. The network admin of your school didn't shutdown the port its running on (which is most likely)
2. Your college doesn't have a sign in page after you log in

There is no security, no login, nothing. If you are on the same network as a Chromecast, it will show up in the extension or apps and you would be able to take over the screen.

Not to mention, the school probably has a policy against unauthorized wireless networks.

You can try to hide the SSID from being broadcasted by the router

My daughter lived in the dorms at San Jose State. The first thing we did every fall was add a wifi router to the LAN in her room. There was never an issue.
Another daughter went to Loyola Marymount. Same thing there.

Why would a school have a policy against additional wifi networks in living quarters and also how would they police that??
I went to a state college of 20,000 students, no way they can stop that. Not that they would.

Also I doubt that if you link up to the schools wifi and try to connect to your chromecast it won't work. Wifi networks like that have many ports and features blocked to prevent you from connecting to other peoples computers/etc who don't have any security settings enabled. Sadly this will most likey stop you from being able to do not shady network stuff yourself. Best bet is set up your own local lan.

My college would find the wireless routers sending signals and search that building for them. It was a pain to deal with. Good luck.

set up a wireless network from your laptop;

Chromecast may not work on Public Wifi

You may not be able to use it on the schools public wifi network without setting up your own access point.
It's a bit tricky to explain, and this is something could be addressed in a future update, but....
Many public wifi networks allow you to connect without a password to the network - and then they limit your access until you click a button to agree to a terms of service. Currently the Chromecast will connect to the network but it appears there is no way for it to 'click the accept button'.
A similar thing happens at many commercial places, like starbucks or macdonalds, where they offer free wifi.
Google tech support says the Chromecast was not designed to be used on public networks.
I do hope it does work out for you, and if it does not, that Google offers an update to resolve this sometime.

It's quite simple actually. There are only 3 non-overlapping 2.4GHz channels and in order to cover a whole college dorm, they need all 3 channels. Any additional APs will DESTROY coverage for the surrounding rooms. If students knew how much their neighbors were killing their wifi, they would hate each other.
I work at a university of about 8,000 students and we have an intern go through the logs on our wireless controllers about once a week, make his rounds with nice little notes that explain the school's policy about personal APs and inform students of the $100 fines for not removing it. Sound pretty controlling? Absolutely! But I've done extensive tests, as have our sister schoolers, and I can tell you without a shadow of a doubt that having individual APs wrecks the wireless for everyone that isn't in the same room as the Ap.
And to the OP: Chromecast will not work on your school's wifi. Did some testing this morning, and it requires P2P over wireless, which no sane network admin would have enabled.

Any way to store multiple networks logged in?I

I was wondering if there is a way to skip network registration everytime we switch places so that each network could be stored and just connect and play?

I've always wanted the same thing. I take one of my chromecasts with me to travel so it switches networks a lot. It would be nice if it remembered networks. Also it would be nice if you could some how sign into guest wifi pages. Right now i'm using the MAC address spoof trick.
Maybe it could get added to Eureka ROM?

The easiest solution is to get a travel router. Let your travel router remember the various networks while setting-up both your device and Chromecast to remember the SSID of your travel router.

It actually does remember (it gets stored into the supplicant file), but it doesn't seem to use anything but the most-recently registered (first?) one.
That would be a nice add for Eureka-ROM, if either
available networks could be checked for connectivity and one that's available is chosen (like phones do)
be able to select another stored WiFi profile from t he web panel (so you could choose the correct one for your destination before you get there)
For now, @eKeith's solution is the easiest.
