TD-SCDMA and Ad Hoc Hybrid Network

One aspect that is always important in mobile networks is the radio planning to ensure that there is coverage over the desired geographical area, without any "holes"; planning of coverage is also important in terms of network capacity and minimizing congestion. This paper considers one aspect of the problem: how to extend coverage beyond that of the base station by using ad hoc network techniques to allow the network to reach users by transiting the connection through a user on the boundary of coverage. An additional benefit is that the approach can "fill in" gaps in coverage within urban areas as well as extending coverage in rural ones. It does this for TD- SCDMA, the 3G network technology proposed for China.
