Semanggi VIP Route Design

Semanggi Drive Test Result

Semanggi Hot Spot Calculation

Semanggi Hot Spot Proposal

3G Microcell Planning Result

Summary



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

Semanggi Drive Test Result

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

Serving Cell with good

received level



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;
