Open Signal Maps Open Signal Maps for Android

 

The best toolkit for improving your cellular and wifi signal.

- Signal direction
- Signal graph
- Map and radar views of cell towers & WiFi routers
- Detailed signal strength data
- Save data to SD card
- Widget (in beta!)
- Save wifi access points and maps of their locations by running the speed test
- History of signal readings

The simplest tactic to improve your reception is to walk in the direction of your signal. Not foolproof, but worth a shot!

Option to contribute to the OpenSignalMaps.com project: were TRUE coverage maps of cell phone networks & wifi data points freely available to all.

Problems? Email us!

Tips:
- Click the wifi-cells toggle button on the bottom left to see wifi routers
- Use wifi and GPS for best speed and accuracy
- Verizon & Sprint users will see only one connected tower at a time
- Not all towers and wireless routers are in our database. Sorry!
- Moving in the direction of your cell tower will not always improve reception due to interference effects and local geography.
- Data is mainly crowd sourced - wireless and antenna locations are calculated by triangulation. This means they are not exact, and sometimes they may be way off. As more people use this app the data will improve.
- Click on the "i" on the overview screen to see more signal stats - including signal RSSI in ASU and dBm

Advanced notes:
- For GSM, cell tower are identified via cell id and location area code (CID and LAC)
- For CDMA, cell towers are identified via Network ID, Base sub-station ID and system ID (NID, BSSID and SID)
- See our website opensignalmaps.com for more detail on using the app and please add your requests for developments.


Were building trustworthy and comprehensive coverage maps for GSM, CDMA; for 2G, 3G & 4G. We think this is the best signal tool you can find, let us know if you think anything is missing.

Networks were mapping: Orange, Vodafone, O2, 3, AT&T, Sprint, Verizon, Movistar, Claro. And over a hundred others.

(key words: opensignalmaps, opensignalmap, opensignal)

Recent changes Open Signal Maps for Android:
We restyled the menus!

We got rid of Turbo mode because people were confused about what it did, and to be honest so were we. We replaced it with "maximum background data collection" this will turn your GPS on suck your battery, but it will collect a lot of data! To stop you leaving it on by mistake it turns on a notification in the top bar.

We added a button to report femtocells as well, thanks to everyone who has been in touch about this.

New Crisis Response maps feature preparedness information for Hurricane Sandy

Already responsible for a reported 41 deaths across the Caribbean, late-season Hurricane Sandy is expected to make landfall again early this week on the East Coast of the United States.

Some are calling the hurricane “Frankenstorm” due to its potential mix of both winter and tropical cyclone weather. Regardless of what you call it, we hope that you get the information you need to make preparations and stay safe if you are in the area. It has the potential to be one of the worst storms the area has seen in decades.

The Google Crisis Response team has assembled a Hurricane Sandy map to help you track the storm’s progress and provide updated emergency information.

 

View larger map. 

On the map, you’ll find the following emergency preparedness information:

• Location tracking, including the hurricane’s current and forecasted paths, courtesy of the NOAA-National Hurricane Center
• Public alerts, including evacuation notices, storm warnings, and more, via weather.gov and earthquake.usgs.gov
• Radar and cloud imagery from weather.com and the U.S. Naval Research Laboratory
• Evacuation information and routes
• Shelters and recovery centers will appear as they become operational
• Storm footage and storm-related YouTube videos, curated by Storyful

We’ve also launched a map specific to New York City, featuring evacuation zone information from NYC Open Data, open shelters, weather information and live webcams.

View larger map.

You can easily share and embed these maps on your website — just hit the “Share” button at the top of the map to get the HTML code. We’ll continue to update these maps as more information becomes available.

Dive into the Great Barrier Reef with the first underwater panoramas in Google Maps

Today we’re adding the very first underwater panoramic images to Google Maps, the next step in our quest to provide people with the most comprehensive, accurate and usable map of the world. With these vibrant and stunning photos you don’t have to be a scuba diver—or even know how to swim—to explore and experience six of the ocean’s most incredible living coral reefs. Now, anyone can become the next virtual Jacques Cousteau and dive with sea turtles, fish and manta rays in Australia, the Philippines and Hawaii.

Get up close and personal with sea turtles at Heron Island, Great Barrier Reef

Starting today, you can use Google Maps to find a sea turtle swimming among a school of fish, follow a manta ray and experience the reef at sunset—just as I did on my first dive in the Great Barrier Reef last year. You can also find out much more about this reef via the World Wonders Project, a website that brings modern and ancient world heritage sites online.

At Apo Island, a volcanic island and marine reserve in the Philippines, you can see an ancient boulder coral, which may be several hundred years old. And in the middle of the Pacific, in Hawaii, you can join snorkelers in Oahu’s Hanauma Bay and drift over the vast coral reef at Mauis Molokini crater.

We’re partnering with The Catlin Seaview Survey, a major scientific study of the world’s reefs, to make these amazing images available to millions of people through the Street View feature of Google Maps. The Catlin Seaview Survey used a specially designed underwater camera, the SVII, to capture these photos.

Whether you’re a marine biologist, an avid scuba diver or a landlocked landlubber, we encourage you to dive in and explore the ocean with Google Maps. Check out our complete underwater collection, featuring a Google+ underwater Hangout from the Great Barrier Reef. And you can always explore more imagery from around the world by visiting maps.google.com/streetview.
