An FDD Multihop Cellular Network for 3GPP-LTE

Free registration required

Executive Summary

The future cellular radio networks like 3G-LTE are based on an OFDMA physical layer. The duplex scheme is preferably Frequency Division (FDD) because of its advantages in long range. Huge area coverage in a cost-efficient way is important problem for the early deployment. Time after time the demand in densely populated areas will grow, so a higher cell capacity over the area is needed. The requirements are expensive to solve with a traditional cellular architecture, because a fiber line access will be needed at any base station location, which are sometimes only a few 100 meters apart.
