At the moment there are the following options:
TDD LTE (Baicells / Telrad / Huawei) PMP450 (Cambium) WiMAX (Cambium/Purewave/Telrad) UBNT M365 (Ubiquity) WiMAX and UBNT do not have any development/future. TDD-LTE claims good NLOS capabilities. PMP450 claims higher sector capacity with LOS (QAM256). LTE claims Standards compatibility while there are not much options to select between. Baicell seem to bring LTE costs down to the Level of PMP450 while both are way above the level of wifi-based 5GHz systems. Baicell is in a testing/beta stage phase. PMP450 may increase performance/NLOS capability with cnMedusa next year. Not seen any announcements where TDD-LTE implementations are heading to next year. We're still running WiMAX for NLOS as there is no clear path where to go
