Analysis of mobile using an android app

1.Using Netmonster app :

The band range of GSM is 1800 .

Based on GSM link budget assuming transmit power is 40 watt.

RXL of the current base station and the distance value based on timing advance is = 2.8 km

calculation for Free Space Path Loss (FSPL):

FSPL = 20 Log10(D)+ 20 Log10(f) + 32.44

= 20 log10(2.8) + 20 log10(1800) + 32.43 =106.47

Rx power should be = 43 dBm – 106.47 = -63.47

Rxl= -89 dBm so additional losses are 25.53

2. To perform walk test of the network ,coverage of the Mobile signal on to the Google Map and Network blackholes

3. Identify the location of call, call drop and corresponding RXL value:

when perform a call ,and move around the indoor coverge = 554 m

RXL value at call = -87 dBm

RXL value at call drop = -95 dB

weak signals due to distances is the biggest cause of the dropped calls . poor reception, bad connection and interference from the transmitter of the tower.

4.

when perform a WIFI call ,and move around the indoor coverge = 1.1 km

RXL value at WIFI call = -99 dBm

RXL value at call disconnect = -105 dBm

the impacts are happening on wifi calling allows to speak in remote locations without using cellphone tower. it is the weaker signal than cellular data.voice quality is poor due to lots of people used at the same time.it is disruptions among other voip preferred.

5.

The calculated edge throughput is for 1 sector for all users. The throughput is Based on the number of users in the cell.
