And just yesterday, 33cm (900 MHz).
They have been soliciting planned and projected uses of the amateur bands between 902 MHz and 3.5 GHz.
I was happy to see there are four 20 MHz wide slices for OFDM for 9cm.
When it comes to life above 900 MHz, the most prevalent thing out there that can easily be adapted to ham radio use is 802.11 network gear.
Ubiquiti, Xagyl, and Doodle Labs all have gear for 900 MHz (33 cm), as well as the standard 2.4 (12 cm) and (5 cm) 5.7 GHz bands. Ubiquiti has 3.5 GHz (9 cm) covered.
So its natural to form a band plan around what can be adapted for ham radio use.
From the ARRL board meeting notes:
4.1.4. At Minute 51 of its January 2012 meeting the ARRL Board assigned to the Executive Committee responsibility for periodic review of the National Broadband Plan Committee Report and managing the implementation of its recommended strategies. Steps being taken to encourage innovative and productive uses of the amateur bands between 222 MHz and 3.5 GHz include the updating of band plans for the four bands between 902 MHz and 3.5 GHz. The committee discussed challenges brought about by increased occupancy of the 1240-1300 MHz band by primary services, and promising developments that may lead to increased amateur broadband activity in the 3.3-3.5 GHz band.
The FCC is asking for input on a number of items, including regulations governing data transmission that inhibit public service/emergency communications by Amateur Radio:
