Soft ware needed in Drive Test

1- TEMS

2- Rout analysis

3-

MapInfo4- Google Earth

Tools needed:

1- Dongle

2-

Mobile

3- GPS

4- HSDPA cart

5-

Inverter

6- Scanner


3/18

Cross Sector in 2G site :

● This is a cross sector between 2 and 4


4/18

Variation on Hopping channel :

Variation in hopping Channel due to hardware problem (DTRU)

● The variation on hopping channel must not increase than 10 db


5/18

Carrier -over - Interference ratio :

Bad C/I due to interference ,there are two types

1- Co-channel interference (Interference between same

frequencies).

2- Adjacent interference (Interference between two different

frequencies).


6/18

How to check the 2G to 2G Relation

System Information type 2bis (Relation of the same band)

System Information type 2 ter (Relation of the different band)

Note : this for idle mode for dedicated 5bis & 5 ter

Cross Sector in 3G site :

● This is a cross sector between sector 1(SC 27) and sector 3

(SC 29)

3G LAC

● From call attempt in layer 3 you can determine the 3G site

LAC


11/18

Missing Relations in 3G :

SC: Scrambling Code in idle mode

AS: Active Set in dedicated mode

MN: Monitored Neighbor can make soft Hand Over to this SC

DN: Detected Neighbor can not make soft Hand Over to this SC


12/18

Shift in Azimuth :

●There is shift in sector 2 azimuth

How to check the Compressed mode process (IRAT)

● Click on layer 3 →Compressed Mode in Event Layer → Measurement Control(DL-

DCCH) in layer 3

IRAT failure :

1- The frequency is not defined .

2- The frequency is defined but with wrong BSIC

3G Events :

e1a Addition of active set e1a, a Primary CPICH enters the

reporting range

e1bremoval of active set, a primary CPICH leaves thereporting range

e1creplacement of AS a non-active primary CPICH becomes better than an active primary CPICH

e1dchange the order of AS, change of best cell


17/18

Etisalat Site acceptance tests

2G 900 :

1- make detailed coverage to the site included by HO between neighbors

2-10 calls ,PS and SMS on every cell (E , F and G)

3-CW & ACW HO to the site

2G Dual band :

1-make detailed coverage to the site included by HO between neighbors(mobile normal)

2-Loop (mobile locked on 900)

3-10 calls , PS and SMS on every cell(E , F, G , A,B and c)

4-CW & ACW HO to the site

Note : RX Level is taken from idle mobile & QUAL is taken from dedicated

3G site :

1-make detailed coverage to the site included by SHO between neighbors

2-Loop video

3-10 calls ,5 video, SMS

4-PS R99 throughput must exceed 350 kb/s

5-HSDPA throughput must exceed 1000 kb/s
