Phase II uses the exact same frequencies that exist on an already P25 TRS. It is just an firmware upgrade on the existing network. It will mean that they will need to start phasing out any existing FDMA (Phase I) only radios. All Phase II is, is adding TDMA ability to multiply the existing talkpaths in existance. TDMA doubles the capabilities for voice and data use. FDMA uses a single path per freq, TDMA uses 2. So if you have an site with 5 freqs, in TDMA that gives you 4 talk paths and a CC. With TDMA you potentially have 8 talk paths. TDMA on the CC adds another data pathway. (Potentially you could do a voice path on the CC Freq, but as I understand it, most of the time it is primarily an extra data path) SO you can add more features also such as having AVL. SMS, etc to the system without adding more freqs. or overloading existing freqs. If they tie in the states LTE system to the Palmetto 800's cores, that adds even more flexibility and options.
