Executive Summary Over the past several years, the high cellular growth rates have focused operators on the capacity and quality of their networks. Improving indoor coverage is an important step towards meeting customer's expectations. By choosing the correct design philosophy, an indoor system will improve call quality also increase capacity. One approach for In-Building coverage is to increase the ambient power of the outdoor Macrocellular system, allowing signals to penetrate outer walls and provide coverage within buildings. This method is used with limited success, due to the wide variation of building penetration loss. In order to provide high quality In-Building cellular service, it is necessary to place the coverage within the building using appropriate designs. Several methods of In-Building coverage solutions exist using passive coax, active coax, fibre optics, Pico RF heads and hybrid combinations of these types. Each approach has a unique set of attributes, which makes it most suited for a particular application. In this document we have discussed In-Building coverage (IBC) design for Siam Discovery, Siam Centre and Siam Car Park using Passive RF Distribution based on CDMA 2000 1x technology. There are 7 levels in Siam discovery including the basement car park. Level 7 to level 30 are office floors of Siam tower that are not covered in this proposal. Siam Centre has 4 levels of shopping plaza and one level of car park. The separate Siam Car Park building has 12 levels of car park including basement. Each car park level is splitted into two levels namely A and B. Our design is based on actual propagation test performed at 800Mhz inside the building under consideration and using standard CDMA design equation which takes into consideration effects of coverage-capacity trade off, link Eb/No performance, log normal shadowing, load characterizations, power control allocation and hand off parameters. Computer simulation for CDMA inbuilding cell planning is not a popular technique as simulating in-building losses due to different kinds of obstructions and dynamics generated by the movement of people is virtually impossible to model. NDC strongly feels that the technique used by us will produce results, which will be very close to practical performance. In the proposed design, we plan to cover three buildings Siam Discovery, Siam Centre and Siam Car Park. The main design criterion is to support 90% of coverage area with FER better than 2% for voice traffic. All the design criterions are discussed in detail separately. In our design we have proposed 115 (112 omni and 3 panel) antennas to make sure we will get -80dBm (-85 dBm in car park) of pilot received power in coverage probability of 90%. As all the technical specifications for BTS are not available there could be 10% to 15% variation in number of antennas to optimise the design so as to suit the BTS selected by BFKT. Based on the traffic analysis two BTS are proposed for covering the desired area. BTS-1 is proposed in the basement level of Siam Discovery. BTS-2 is proposed in the basement level of Siam Centre to cater Siam centre shopping floors, Siam centre



basement car park and Siam Car Park building. RF distribution system using passive components is proposed to cover the 3 buildings. It is assumed that we will get permission to install the feeders along the walkway between Siam Car Park and Siam Centre. Otherwise an alternative solution such as optical fiber repeater will be used to connect these buildings. BTS 1 is proposed with one sector to cover Siam Discovery. BTS-2 Sector 1 and Sector 2 will be serving Siam Centre and sector 3 will be used to cover Siam Car Park. Figure- (1.1) shows, proposed sectorisation plan for IBC sites. Our design is flexible enough to be converted to a multi carrier traffic allocation (MCTA) or if required with a small change we can sectorise the site to support the required capacity. We have also presented detail analysis to support 9.6 Kbps voice traffic in the coverage area. Coverage range for Circuit Switch and Packet switched data traffic for 9.6 Kbps and 76.8 Kbps is also presented. The detailed coverage planning and capacity calculation is also discussed in the report. Once the site is integrated and is on air, optimisation will be undertaken to improve the performance of site.

(3.3) Coverage-Capacity Trade Off:

Cell radius depends on the interference and therefore on the numbers of transmitting users within the cells and their services.

A given coverage is directly linked with certain traffic within the cell. Cell shrinking in case of increasing number of active users is called cell breathing.

Coverage and capacity cannot be treated separately.

Cell range depends on Cell Load

Number of users dependent on cell range

Cell load depends on number of users within the cell

The range performance of a CDMA system is determined by its link budget and path loss in the environment it encounters. The following link budget is used to understand the performance of forward link and reverse link. (3.3.1) Path loss Model In the same way that the Okumara-Hata model has been developed semi-empirically for macrocell coverage predictions, the Keenan-Motley model has beenfor indoor wave propagation predictions. COST 231 has accepted this simplified equation is

L = 31.5 + 20log(d) + NwW -- (3.1) Where; L is the path loss between isotropic antennas (dB). D is the transmitter receiver separation (m). Nw is the number of walls passed by the direct ray. W is the wall attenuation factor (dB)

The approximate formula considering wall loss of 0.2 dBm could be taken

Planning Group Oct. 2001


Lp (dB) = 50 +0.5 x D -- (3.2)

Where; D is the distance in meters Lp is the total loss (propagation plus walls) This gives good approximation within 10-50 meters.

For scenario like Bangkok the wall attenuation factor is assumed to be 0.5 dBm which is also in agreement with the measured results. The approximate formula considering wall loss of 0.5 dBm could be taken as;

Lp (dB) = 50 + 0.8 x D -- (3.3)

Figure (3.1) below shows the path loss as a function of distance using standard Keenan-Motleys equation.

(3.3.3) Link Budget for Circuit Switched and Packet Switched Data


(3.3.4) Link Budget Description The following sections provide descriptions of the individual link budget template items. Descriptions apply to both forward and reverse links unless specifically stated otherwise. For the forward link the base station is the transmitter and the mobile station the receiver. For the reverse link the mobile station is the transmitter and the base station the receiver.

Average Transmitter Power Per Traffic Channel (dBm) The average transmitter power per traffic channel is defined as the mean of the total transmitted power over an entire transmission cycle with maximum transmitted power when transmitting. Maximum Transmitter Power Per Traffic Channel (dBm) Maximum transmitter power per traffic channel is defined as the total power at the transmitter output for a single traffic channel. A traffic channel is defined as a communication path between a mobile station and a base station used for user and signalling traffic. The term traffic channel implies a forward traffic channel and reverse traffic channel pair. Maximum Total Transmitter Power (dBm) Maximum total transmit power is the aggregate maximum transmit power of all channels.

Cable, Connector, and Combiner Losses (Transmitter) (dB) These are the combined losses of all transmission system components between the transmitter output and the antenna input (all losses in positive dB values). The value is fixed in the template.

Transmitter Antenna Gain (dBi) Transmitter antenna gain is the maximum gain of the transmitter antenna in the horizontal plane (specified as dB relative to an isotropic radiator). The value is fixed in the template.

Transmitter EIRP Per Traffic Channel (dBm) This is the summation of transmitter power output per traffic channel (dBm), transmission system losses (-dB), and the transmitter antenna gain (dBi), in the direction of maximum radiation. The equation is

PEIRP = PTX, Max - LTX + GTX -- (3.4)

Total Transmitter EIRP (dBm) This is the summation of the total transmitter power (dBm), transmission system losses (-dB), and the transmitter antenna gain (dBi). The equation for forward link is

PEIRP, TOTAL = PTX, Max - LTX + GTX -- (3.4)

And Lb is subtracted from the equation for reverse link.



Receiver Antenna Gain (dBi) Receiver antenna gain is the maximum gain of the receiver antenna in the horizontal plane (specified as dB relative to an isotropic radiator).

Cable, Connector, and Splitter Losses (Receiver) (dB) These are the combined losses of all transmission system components between the receiving antenna output and the receiver input (all losses in positive dB values). The value is fixed in the template.

Receiver Noise Figure (dB) Receiver noise figure is the noise figure of the receiving system referenced to the receiver input. The value is fixed in the template.

Thermal Noise Density, No (dBm/Hz) Thermal noise density, No, is defined as the noise power per Hertz at the receiver input. Note that (h) is logarithmic units and (H) is linear units. The value is fixed in the template.

Receiver Interference Density is Io (dBm/Hz) Receiver interference density is the interference power per Hertz at the receiver front end. This is the in-band interference power divided by the system bandwidth. The in-band interference power consists of both co-channel interference as well as adjacent channel interference. Thus, the receiver and transmitter spectrum masks must be taken into account. Note that (i) is logarithmic units and (I) is linear units. Receiver interference density Io for forward link is the interference power per Hertz at the mobile station receiver located at the edge of coverage, in an interior cell.

Total Effective Noise Plus Interference Density (dBm/Hz) Total effective noise plus interference density (dBm/Hz) is the logarithmic sum of the receiver noise density and the receiver noise figure and the arithmetic sum with the receiver interference density, i.e.

NT = 10 x log (10(Io/10) + 10((No+NF) / 10) ) -- (3.5)

Information Rate is 10 log(Rb) (dBHz)

Information rate is the channel bit rate in (dBHz); the choice of Rb must be consistent with the Eb assumptions.



Rise Over thermal Noise rise is a result of in-cell and out-of-cell interference. Link Budget includes these value to indicate the level of cell shrinkage that is expected from a given loading. Typical performance curve for the reverse link in CDMA system is shown in figure (3.2).

Figure (3.2)

Required Eb/(No+Io) (dB) The ratio between the received energy per information bit to the total effective noise and interference power density needed to satisfy the quality objectives specified in Table 1.0 under condition of section 1.2.2 channel model. Power control should not exceed the ceiling established by the sum of the log-normal fade margin plus hand-off gain. Note: Diversity gains included in the Eb/(No+Io) requirement should be specified here to avoid double counting. The translation of the threshold error performance to Eb/(No+Io) performance depends on the particular multipath conditions assumed.

Receiver Sensitivity (dBm) This is the signal level needed at the receiver input that just satisfies the required Eb/(No+Io). The equation for reverse link is

PRXmin = NT + 10 log(Rb) + Eb/(No+Io) + LB -- (3.6)

And there is no LB calculated for forward link.

Handover Gain/Loss (dB) This is the gain/loss factor (+ or -) brought by hand-off to maintain specified reliability at the boundary. Assume equal average loss to each of the two cells. The handoff gain/loss shall be calculated for 50% shadowing correlation. The proponent must state explicitly the other assumptions made about hand-off in determining the hand-off gain.



Explicit Diversity Gain (dB) This is the effective gain achieved using diversity techniques. It should be assumed that the correlation coefficient is zero between received paths. Note: Diversity gain should not be double counted. For example, if the diversity gain is included in the Eb/(No+Io) specification, it should not be included here.

Other Gain (dB) An additional gain may be achieved due to future technologies. For instance, Space Diversity Multiple Access (SDMA) may provide an excess antenna gain. Assumptions made to derive this gain must be given by the proponent.

Log-Normal Fade Margin (dB) The lognormal fade margin is defined at the cell boundary for isolated cells. This is the margin required to provide a specified coverage availability over the individual cells.

Maximum Path Loss (dB) This is the maximum loss that permits minimum performance at the cell boundary. The equation is

LMAX = PEIRP PRX,min + GRX - LRX + Gdiv + GHO + G other -

Maximum Range (km) The maximum range is computed for each deployment scenario. Maximum range, Rmax, is given by the range associated with the maximum path loss. The equations to determine path loss are given in section 3.2 of this document.



(4.0) Conclusion

I. After analysing the traffic for Siam Centre and Siam Car Park we have concluded that, we need 2 TRxs and 1 TRx respectively to support the traffic requirement. It is also understood that the capacity of TRx used for Siam car park may not be loaded significantly.

II. 1 TRx is proposed for Siam Discovery.

III. Our analysis shows that we can support 23-users/ sector of 9.6 Kbps of voice

traffic.
