QUALCOMM – WCDMA Network Planning and Optimization.pdf

Taken from WCDMA Network Planning: Ensuring that the RF coverage is sufficient within the network should start naturally with a good RF network plan [2]. Network planning is, may be even
more for existing operator, an area that is too often overseen. Greenfield operator have the advantage of starting from a clean plate while incumbent operator already have a set of site that they are compelled to use even if these sites were originally acquire to fit in a network with different coverage and capacity limitation.
So what is a good RF network plan?
A good network plan should address the coverage and capacity requirement of the area considered, but also be sufficiently flexible to allow network expansion without major change of the existing sites.
In WCDMA, the coverage and capacity requirement cannot be considered independently, but should be planned at the same time with proper guidelines.
This relation between coverage and capacity is often referred to as the “breathing effect” of WCDMA. Comparing with TDMA/FDMA technologies, such as GSM, the coverage of a WCDMA network cannot be planned independently of the load on the network. The load on the network
will impact the coverage in mainly two different ways, depending on which link (Uplink or Downlink) is considered. On the uplink, as more users are added to the network, higher noise would be detected at the node Bs. This increase in noise, called rise over thermal, requires each of the phones or data cards (UE) to increase its transmit power to overcome this noise increase:
effectively the uplink coverage is reduced by this required increase in transmit power. This effect has been documented and can be summarized by the riseover-thermal versus load curve illustrated in Figure 2: as an example, when the load is 50% of the pole capacity, the coverage is reduced by a factor of 3 dB.
