| 3650 - 3700 MHz | Proposed - Fixed Wireless Access |
On this band there are no current adjacent Part 15 allocations. However, a chunk that doesn't appear to overlap our allocations has been proposed. It is possible with transverters to take consumer off the shelf 2.4 GHz 802.11 hardware and have it operate on this ham band. Ubiquiti Networks has a device for this band too that is compatible with the 802.11 Atheros chipset. Since the band is unshared by Part 15 there may be some advantages to this, such as fighting interference and to keep out Part 15.

Ubiquiti XR3 uses a 2 GHz frequency conversion, and is detected as a 5 GHz cards. So you select the corresponding 5ghz channel. I.E>5.5ghz = 3.5Ghz
The XR3 is available in three different models with frequency operation spanning 2.7GHz to 3.7GHz.
The XR3 is fully compatible with the publicly available Atheros Linux MADWIFI driver and can instantly transform existing 802.11 based products into market-ready 3GHz solutions by simply changing out the mini-PCI radio. The XR3 leverages a variety of advanced features including scalable channel bandwidths of 5/10/20/40 MHz, compression, and more.
