TD-SCDMA is more suitable than other any kind of 3G network to use the indoor outside different frequency network way.Someone the city network planning is precisely carries on the plan based on the above basic idea, in the cover, the capacity, the quality, will invest four between discover the best combining site to construct by the reasonable investment have met in the near future and the forward service demand and achieve certain grade of service the mobile communication network. Along with mobile service's unceasing development, the wireless network needs to meet this kind of growth need through the dilatancy. TD-SCDMA has many kinds of dilatancy ways, including increases the power on the original base depot, to increase the new sector and the new carrier. Although adds the new base depot to be possible to solve the capacity problem to a great extent, but considered the new station construction cost and to the peripheral base depot's influence, selects time this method needs to give careful consideration.
