General Carrier Design
From Capacity Estimation to TDMA Structure

Optimized Three Carrier Solution
A similar procedure can be used to optimize TDMA frames for multiple carrier solutions. We
present here an optimized solution for the 3 carrier network for which the user data rates have
also be estimated by the Capacity Calculation presented at the beginning of this section. All the
assumptions made so far are still valid, however we must now find a solution which provides
sufficient user data rates for all 3 carriers. The proposed optimized solution is presented in the
following screenshots.

Adjustment and Optimization Considerations
1. For the 3 carrier solution we have selected smaller time slots which carry only 2 voice
calls per slot instead of the 3 calls we used for the 1 carrier solution.
2. As the individual carriers are smaller in this case, the number of time slots is still within the
