The multi-hop, ad-hoc wireless networks of ODMA can be shown to reduce overall transmission power compared with single hop transmission, however, for simple receivers and low user density, the actual capacity of UTRA TDD may be marginally reduced from the maximum non-relaying capacity. This paper analyses the capacity of ODMA in relation to the coverage of a cell. It is shown that after the coverage limit of non-ODMA UTRA TDD has been reached, ODMA will provide enhanced coverage. As the number of calls and/or quality of service is decreased the cell coverage can be increased beyond conventional coverage-capacity trade-offs, allowing operators a far greater degree of flexibility
