You are correct, there are chipset availbale support wide band. If we look at V-band spectrum available globally, many country still not open V-band yet, some of them only allow PTP application. We are workin actively to advocate open V-band for PMP/PTP use with local regularoy agency. Ideally, we want the product can support complete V-band. Today the limiation comes both chipset and location regulation.
Mikrotik support at least 1 - 3. I believe they support 1 - 4.5.
