Network Signal Info

Google Earth view with cell

tower position (KML file).

A small circle = low signal

reception, a bigger circle = good

reception.

Network Signal Info Pro

“Network Signal Info Pro” provides detailed information on your currently used

network, regardless whether you are using WiFi or a cellular connection.

The Pro version (compared to the free version) has no ads, a NEW addional cell

tower database from Unwired Labs with

more than 80 million entries

, a NEW

MOBILE SIGNAL TRACKER function that generates a KML file for use with Google

Earth, more widgets, a MOBILE SIGNAL LOST SERVICE and much more.

The “mobile signal lost” function runs perfect, it only costs a little battery power

and works fine. Only the notification for “get mobile signal” works to often.

Bar and percent classification

Until version 2.02.01 the app have a new bar and percent classification. It is

necessary to distinguish between two groups.

Group 1

: GPRS, EDGE, UMTS, HSDPA, HSUPA, HSPA+ … (2G and 3G networks)

Group 2

: LTE (4G)

Group 1 (2G/3G)

has under Android a range from

0 to 31 ASU

or in RSSI

(Received Signal Strength Indikator) dBm from

-51 dBm to -113 dBm.

The value 99 is equal to unknown or not supported. You can convert the ASU

value to RSSI with the following formal: RSSI [dBm] = (2x ASU) – 113

The app used a percent range

from 0 to 28

(0 ASU = 0%, 28 ASU = 100%)

.

I stopped with 28 because it is not important if you have 28 or 31 ASU, but it

looks a little bit better when you have e.g. 15 ASU, the bars in statusbar shows

shows full reception, and you have “only” under 50% signal reception.

The

bars

in the app used the range from

0 ASU to 24 ASU.

If you have e.g. an

ASU greater than 23, all bars are shown.

For your Infomation: Almost all phone manufacturer shows all bars in the

statusbar, if the ASU is greater than 16 or 17.

Group 2 (4G)

has under Android a range from

3 to 95 ASU

or in RSRP

(Referenz Signal Received Power) from

-137 dBm to -45 dBm

. You see under

LTE RSSI is not used and the range is much bigger.

You can convert the ASU to RSRP under following formal:

RSRP [dBm] = ASU – 140 or

ASU = RSRP [dBm] + 140

The app used a LTE percent range

from 3 to 70

(3 ASU = 0%, 70 ASU = 100%

or -135 dBm = 0%, -70 dBm = 100%). The bar range is the same.

Now with widgets:

1×1, 2×1 and 2×2 in 3 different styles.

(If you can’t find widgets, please copy the app to phone memory)

I have especially worked on the visualization of the WiFi and mobile signal

strength. They have received special importance. Normally they are only divided

into weak, good and excellent signals. Graphically there are mostly “only” three to

five bars shown as a mobile signal and three “waves” shown as a WiFi connection.

My app differentiates the signal strength into a total of 14 bars. This will give you

a quick visualized and detailed information on your signal strength.

In addition to the more sophisticated graphical representation of the signal

strength you will also be able to see some more interesting information.

With “Mobile Signal”:

Network operators, sim provider, phone type, network type, network strength in

dbm and ASU, data state, data activity, country code of the mobile phone, device

ID, IP address (internal und external), roaming state.

In “WiFi signal”:

WiFi-Name (SSID), BSSID, MAC address, maximum WiFi speed, IP address,

external IP address, net capability, net channel, subnet mask, Gateway IP

address, DHCP server address, DNS1 and DNS2 address.
