1.3 System Expansion

Following the lower power more antennas model, deployed system can be reused for 3Gnetwork with minor modifications in the backbone.

1.4 DBS Information 3900

A single BTS3900 cabinet holds up to 2 TRXs. It performs the functions such as Transmitdiversity, 4-way receive diversity.

The BTS3900 cabinet has large power and large capacity. It is small and easy to installand saves the cost on the equipment room. Especially, it uses the direct air coolingtechnology, which saves the cost on the heat exchanger, power consumption, andMaintenance AC inputs and DC inputs 110 V AC (dual live wires) and 220 V AC 48 VDC. DC battery power supply

The BTS3900 has strong environment adaptability. It can work under the Temperature of40Cto +55C. It supports the outdoor application with IP55 protection level.

2 Design Principle

In the system designs for GSM1800 network, the EIRP of the indoor Omni Antenna for GSM1800 isfrom 5dBm to 10dBm.The coverage distance is about 15 to 20m, this depends on the indoor structureLink budget for the antennas coverage distance is shown below: The in-building aerial transmission loss is calculated as follows:

Ld=32.4+20lgD(Km) + 20lgF(MHz)D = distance from the antenna to the mobile station (Km)F = carrier frequency (MHz)

The total path loss is as follows:

L=Ls+LdLrLs = loss led by the internal obstruction.Lr = loss led by the internal estimate.

The minimum in-building coverage field strength is:Emin = P - L

P means the antenna output power

The aerial transmission loss of different distance is as follows:As to the GSM1800 system:

PL(dB) =32.45+20lg(1800)+20lgd(km)= 97.5+20lgd(km)

D 1m 10m 20m 25m 30m 35m 40m

Ls 37 57 63 65 67 68 69

For In-building signal, formula is as follow:L=LD+10LgD (m) + Lr

Lr experienced values are as follows:

1800MHz

Wood Board 68dB

Glass 810dB

Brick Wall 1416dB

Concrete Wall 20-25dBElevators 35-40dB

SupposedThe output power of the antennas for GSM1800 P0=7dBmThe gain of omni antenna G0=5dBi, the FAF of the wall is about 20dB,L (20m) = 63+10lgD (m) +FAF

= 63+13+20=96So the RSSI=P0+G0-L=7+5-96=-84 (dBm)So the design of the GSM1800 system can satisfy the systems requirements.

3 Signal Leakage Analysis

Indoor signal leakage is mainly caused by the antenna signal leakage in the lower parts of building, ifthe building is higher, the route loss will be larger, if the lower building antenna can meet the levelleakage index, and then the high building antenna can also meet the level leakage index. Theantenna to cover the elevator can be installed in the elevator shaft, as the walls of the elevator shiftwill absorb the signal, and there will be very little leakage in this area, a sample will be taken from theceiling mounted antenna installed on the first floor to analyze the leakage of the signal.

The Lower Floors leakage Analysis (Ground Floor):Now we count the signal field intensity in the distance of 20m (leakage outside 10m away)Work out the deviation of path loss between D1 and D2 according to the path loss Formula:

LD1- D2 =20log20/10=6.0dBThe result from above analysis adds glasses loss of windows 6dB, so the path loss is 12dB from theedge field to outside 10m away.Even though the signal of GSM close to the edge of windows can reach to -80.0dBm and the signalfield intensity of leakage outside 10m away is under -92.0dBm,it can satisfy the level requirement(-90.0dBm).

4 Design Objective

Principle of the In-building Coverage System The relative international standard about GSM900/1800 system The electro-magnetic protection requirements of the radio Management authorities in

PAKISTAN. Other laws and regulations of PAKISTAN. Inspection material and testing data on site.

5 Coverage Requirements

Design Technical Indexes of GSM System

2G System KPI

RSSIFloor: RxLev at edge -85dBm

Elevator and Basement : RxLev -90dBm

Coverage Probability 95% coverage area meets the RSSI requirements

Call Quality More than 95% coverage areas meet the requirements ofRxQual < 4.

EiRP of Indoorantenna

Floor antenna EiRP: < 12 dBm/carrierElevator antenna EiRP: 2 to 6 dBm/carrier (In case of

Elevator coverage)

LeakageAt a distance of 10m from building RSSI of indoor cellshould be 15 to 20dB less then RSSI of outdoor cell.

HandoverThe smooth handover between the indoor cell and outdoorcell should be ensured

The voice traffic of mobile user when busy is set as 0.02Erl. The call loss rate of wireless channels is set as follows:

The call loss rate of TCH is 2% The call loss rate of SDCCH is 0.1%

GSM interference protection ratio is as follows: Co-channel interference protection ratio:

C/I 12dBwithout hopping frequencyC/I 9dBwith hopping frequency

Adjacent channel interference protection ratio:200 KHz adjacent channel interference protection ratio: C/I -6dB400 KHz adjacent channel interference protection ratio: C/I -38dB

The voice quality score of the indoor coverage system is above 96. The score iscalculated by the weighted averages method :

( level 0level 1level 2) 1 + (level 3level 4) 0.8 + (level 5level 6) x 0.5level 70.2Here level 0 means the sample points with the voice quality 0 covers the total sample points.
