cater more traffic
and improve the
Quality
Clearance the RF

the number of
Dominant Cellserving one area
Make the CPICH as

reduce the
pollution, minimize
the overlapping
Active Cells Impact of Lowering
CPICH is coveragereducing, and need
more BTS to
guarantee the

More BTS make the
user closer to the

the transmit power ofBTS and UE and
reducing the

Area profile :
- VVIP route, as representative of Telkomsels
network- Wide route with 8 ~ 12 road lines
- Heavy traffic jam route
- High CS & broadband traffic route
- Mostly served by macro sites with HRB obstacles
& some with high utilization
- BTS tower restricted area along the route
- BTS tower restricted in SCBD area
Goal:
- Best and excellent VIP route dedicated network in
coverage, capacity, and quality
- Efficient network with capacity pooling
- Future ready network (LTE1800)
- Environment friendly tower
Strategy:
- BTS Hotel phase 2 with feeder-less along the route
- 3G/HSPA+ service with LTE ready
- Simple camouflage pole

Good RSCP, but
Bad Ec/No due to Pollution from surrounding site,
Too many BTS cover ing that area : Shelter Polda,
Shelter Semanggi, Golfsenayan
Bad RSCP, Bad Ec/No,
Due to no dominant

General
CoverageDistance = 11 km
Pole to pole distance = 500 m
Coverage = 11000/500 + 1 = 23 poles
Capacity
Number of line = 10
Total distance = 110 km = 110000 m
Car to car distance = 5 m
Number of car = 110000/5= 22000 cars
Number of people = 22000 cars * 3 = 66000 peoples
Telkomselssubscribers (incl. growth) = 40%*125% * 66000
= 33000 subs
assumption (3G Subs : 2G Subs = 50% : 50%)
2G subs = 16500 subs
3G subs = 16500 subs
Data 3G = 16500 * 256 kbps / 15 = 282 MbpsTraffic 3G per Sector (2 Carrier) = 13 Mbps
Traffic 3G per Sector (3 Carrier) = 19 Mbps
3G cell = 22Sector of 2 carriers
3G cell = 14 Sector of 3 carriers
If Number of Poles > Number of Sector, then there are 2
poles or more becomes one logical sector
Capacity per cell
Total Peoples = (300 m * 10 / 5 m) * 3 =1800
Telkomsel Subs = 40%* 1800 = 720
Subs
2G = 360 subs 360 * 20mE/subs
= 7.2 Erl
HSDPA = 360 * 75% = 270 subs
HSDPA Concurrent user = 270 /15
= 18 users
Based on coverage proposed and
drive test result, number of poles
required are 12 poles (12 BTS
Hotel, with 16 Sectors)
Configuration Proposal
Logical Sector = 16
3G Carrier : 2 x 16 = 32 Carrier
3G CE : 128 x 16 = 2048 CE
3G WBBPf : 2048/756 = 3~4 modules

For DC Site Cell 1,12,13,14, the power consumption of RRU is around 636W
(1RRU3929+1RRU3828). Considering two AC lamps consume 2x100w, So the total power
consumption of single sector site is around 836W;
For AC Site Cell 5, RRU3828 is 184W.
For AC Site Cell 9,10,11, power consumption will increase slightly (10%) due to additional ACtransfer module compared with DC power supply site.
For AC Site Cell 3 & 4 and Site Cell 6 & 7, the power consumption of AC RRUs is 1420W (2 AC
RRU3929 AC+2 AC RRU3828). Assume the lamp will consume 2*100W power, so the total power
consumption of dual-sector site is around ~1620W;
