. The mobile/BTS do not receive power control commands during compressed frames, and this is why larger steps need to be used. This is a special case that is used during the execution of inter-system measurements.) Power control processes have a direct impact on the coverage and capacity of the network. Air-interface capacity in the downlink is more critical and is dependent on the transmitted interference. If the required transmitted power can be reduced to a bare minimum, the capacity can be increased. However, in the uplink, both the transmitted and received power will increase interference to, respectively, adjacent cells and users of the same cell. The better the isolation between the cells, the higher the capacity, and decreasing power levels to the minimum required can increase this isolation. 7.5.7 Handovers WCDMA networks will experience a tremendous increase in the number of handovers taking place in their radio networks. Handover is a phenomenon that takes place when the mobile subscriber is moving around. This is done SO as to give the best coverage and quality to the subscriber. The following types of handover exists in WCDMA radio networks: intra-mode handover inter-mode handover. Apart from this, there are two categories of handover: soft and hard. Handover was a phenomenon existing in GSM networks as well. In GSM networks, as every cell had a different frequency, the handover was called hard. In a WCDMA radio network, as the frequency re-use factor is 1 only, a different kind of handover is used, described as soft. Intra-mode handover constitutes soft, softer, and hard handovers, whereas inter-mode handover will take place in a scenario where the FDD and TDD modes exist simultaneously. Here we will concentrate only on intra-mode handovers. The intra-mode handover procedure is based on the measurements performed on the common pilot channel. When the mobile is in a position that is in between two cells (i.e. in a region of overlapping coverage), then it is connected simultaneously to two different s
