【软件介绍】
感谢Balatan大神分享！！！

信号雷达 Open Signal Maps，通过手机基站定位测试信号强度并在地图上是表示的软件。

功能：
- 地图上显示基站。
- 地图上显示附近的无线路由器。
- 手机基站方向。
- 图表显示信号强度随着时间的推移。

✓ Signal compass points you in the direction your signal is coming from, just walk towards it!
✓ WiFi map allows you to easily locate nearby public networks.
✓ Coverage maps allow you see the best/worst places for signal.
✓ Speedtest feature allows you to see the true speed of your connection (download, upload & latency)
✓ NetworkRank shows which carrier is best in your area.
✓ See local cell towers.
✓ Free and ad-free

You can also:

✓ Help improve our crowdsourced and impartial maps by contributing data.
✓ Share your findings and compare your connection with other users.
✓ View your history of signal readings.
✓ test upload, download and latency
✓ Save your data to SD card.
✓ Signal booster for compatible phones

SMS Permission required to count the number of SMS sent to track your usage, SMS are never read (use a packet sniffer to check!)
Phone settings permission allows network reset on certain Android versions

Based on our community-generated data we are able to help keep you better connected by giving you a practical solution to the problems of slow mobile internet and dropped calls. Simply follow our signal compass to walk towards better phone signal or see our in-app coverage maps to work out which carrier is best for where you are, useful if you"re thinking about changing. Our wifi maps help you find local public-access wireless networks (WAPs).
The Stats tab helps you to keep track of your usage, so there’s no danger of you going over your plan limit on data, voice or text. (NB – this is why the app needs permission to access contacts and SMS, these are the permissions needed to count calls and texts, messages are never accessed or read!).

Maps not updated in real-time. Don’t worry though, we log the information you share with us to improve our coverage maps and signal information. We’re working hard to make sure the data you contribute to the project is available to everyone as quickly as possible.
Tips:
- Not all towers and wireless routers are in our database - we’re working on it!
- Verizon & Sprint (CDMA) users will see only one connected tower at a time
- Moving in the direction of your cell tower (the signal compass) will not always improve reception due to interference effects/local geography.
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).
