Little, we translated the air interface advantages of TDD taking into account multiple operator deployment limitations into the economics of deployment under representative traffic scenarios; the quantity of network elements, related network capital and operating costs over ten years, and NPV of the projected operating cash flowsNPV savings up to 50% for the capacity enhancements deploymentNPV savings of about 25% for the wide-area broadband data deploymentAn additional saving of 15% can be achieved by using 10 MHz of spectrum for TDD wide-area broadband service rather than 5 MHzSavings increase with subscriber density and severe multipath environment
