(2) Description of why an STA is needed.

The FCC is considering Mimosa’s proposal to allocate the 10.00 – 10.45 GHz band for terrestrial fixed
wireless services in RM-11715. Mimosa seeks to test equipment in that band in order to collect, and then
provide to the FCC and other government agencies, real-world information about the utility of that band
for fixed services and the ability to use that band on a shared basis with incumbent users, including
government radiolocation services. Grant of the license will allow Mimosa to test its technology in the
10.00 – 10.45 GHz band.

(3) Description of the operation to be conducted and its purpose.

The operation will involve field deployment and continued testing of Mimosa Network’s new 10 GHz radio
technology. The deployment will be a series of back-to-back point-to-point links, stating from a data
center in Milpitas, CA, relayed at an intermediate tower at Crystal Peak in Santa Clara County, CA and
then transmitted back to another data center in Santa Clara.

The back-to-back nature of the field deployment will evaluate the spectrum re-use model, achieved
through timing synchronization across multiple radios.

(4) Time and dates of proposed operation.

Authorization is requested for one (1) year and one (1) month, from April 20, 2017 to June 1, 2018.
Mimosa will notify the Department of Defense at least one week prior to any testing. In the event that
interference is reported, Mimosa will immediately cease transmissions.

(5) Class(es) of station (fixed, mobile, fixed and mobile) and call sign of station (if applicable).

The transmitting station will operate in fixed mode.

(6) Description of the location(s) and, if applicable, geographical coordinates of the proposed
operation.

The transmitters will be located at:

Hurricane Electric Data Center, Milpitas CA: 37° 28' 15.79" / -121° 55' 13.42"
Crystal Peak, Tower side, Loma Prieta CA: 37° 6' 49.51" / -121° 50' 10.14"
Private Property, Carmel Valley, CA: 36° 31' 18.88" / -121° 44' 30.56"
Equinix Data Center, Santa Clara, CA: 37° 22' 41.75" / -121° 57' 17.94"
Chual Spur, Tower side, Loma Prieta, CA: 37° 7' 9.3" / -121° 50' 2.58"

The links will be as follows:

Hurricane Electric to Crystal Peak: 169 degrees (orientation in the horizontal plane).
Crystal Peak to Hurricane Electric: 349 degrees.
Crystal Peak to Carmel Valley: 173 degrees.
Carmel Valley to Crystal Peak: 353 degrees
Equinix Data Center to Chual Spur: 160 degrees
Chual Spur to Equinix Data Center: 340 degrees

(7) Equipment to be used, including name of manufacturer, model and number of units.

Experimental Equipment:

Mimosa Networks experimental 10 GHz radio. Architecture consists of 5 GHz 802.11ac (WiFi), dual 80
MHz channels, and dual polarizations, with the radio up- converted to 10 GHz using discrete RF circuits.
