OpenSignal: GSM WCDMA LTE WI-FI - 2G 3G 4G (Cell Coverage) Signal Maps

Here at telecomHall, as you already know, we share tips and interesting suggestions geared to the technical audience, people who works with Telecom and IT. But today we are going to talk about a very interesting application, but that doesn't only apply to these professionals, but to everyone that use wireless devices.
Introducing OpenSignal, an application that performs Cellular and Wi-Fi Networks data collection, and use it in building a comprehensive public map with information for all these networks around the World.

And gets it through a technique that should be increasingly exploited in other applications: the collaboration of all users, with beneficial results to all.

Then, let's go to see the application?

UMTS/GSM/LTE/CDMA/EVDO Network Monitor and Drive Test tool

This is a fieldtest/netmonitor application for UMTS/GSM/LTE/CDMA/EVDO network.

The application monitors the serving CELLID, LEVEL, QUAL, MCC, MNC, LAC, technology, cell serving time and neighbor cells CELLID/PSC and LEVEL.

LEVEL and QUAL depend on technology:
- 2G - RXLEVEL and RXQUAL
- 3G - RSCP and ECNO
- 4G - RSRP and RSRQ

Only for 4G also SNR and CQI are monitored.
The reported measurements depend on the phone and are not available on all mobiles. For example most phones do not report RXQUAL on GSM and only some report ECNO on 3G.

• Signal 2

Signal 2 is a utility created by iPhone Dev Team member planetbeing that displays information about the cell tower your iPhone is connected to as well as neighbouring cells. It detects and maps the location of all nearby cell towers so that the user can easily get a good idea of their cellular coverage or where to go to get the best cellphone reception. On an unlocked phone, a user can swap SIMs and determine which carrier is best for him or her based on cellular coverage. In addition the map, other useful technical data is displayed including RSCP (signal strength) in dBm and Ec/N0 (signal quality) to all neighbours, the PSC of the cells, as well as the frequency each cell is broadcasting in.

Signal 2 is exclusively available from the Cydia Store on jailbroken iOS devices with cellular radios running iOS 5 and above.

You can download from some buy it or search from some hack source such as:iphone.gsm.vn or appt.xellize.com.
