LDMS does not use the same spectrum -- 28 - 31 Ghz -- as the recently released TV white spaces 54 - 608 Mhz. This was discussed last fall. Val's old junk surplus from 1999 never heard of the White Spaces of 2009 -10. LOL

Some definitions from the FCC ruling which may help in investigating available TV White Space channels:

(c) Fixed device. A TVBD that transmits and/or receives radiocommunication signals at a
specified fixed location. A fixed TVBD may select channels for operation itself from a list of
available channels provided by a TV bands database, initiate and operate a network by sending
enabling signals to one or more fixed TVBDs and/or personal/portable TVBDs. Fixed devices
may provide to a Mode I personal/portable device a list of available channels on which the Mode
I device may operate under the rules, including available channels above 512 MHz (above TV
channel 20) on which the fixed TVBD also may operate and a supplemental list of available
channels above 512 MHz (above TV channel 20) that are adjacent to occupied TV channels on
which the Mode I device, but not the fixed device, may operate.

(i) Personal/portable device. A TVBD that transmits and/or receives radiocommunication
signals at unspecified locations that may change. Personal/portable devices may only transmit
on available channels in the frequency bands 512-608 MHz (TV channels 21-36) and 614-698
MHz (TV channels 38-51).

(m) Television band device (TVBD). Intentional radiators that operate on an unlicensed basis on
available channels in the broadcast television frequency bands at 54-60 MHz (TV channel 2), 76-
88 MHz (TV channels 5 and 6), 174-216 MHz (TV channels 7-13), 470-608 MHz (TV channels
14-36) and 614-698 MHz (TV channels 38-51).

(a) Power limits for TVBDs.
(1) For fixed TVBDs, the maximum power delivered to the transmitting antenna shall not exceed one
watt; this maximum applies regardless of the number of TV channels on which the device operates. The
power delivered to the transmitting antenna is the maximum conducted output power reduced by the
signal loss experienced in the cable used to connect the transmitter to the transmit antenna. If transmitting
antennas of directional gain greater than 6 dBi are used, the maximum conducted output power shall be
reduced by the amount in dB that the directional gain of the antenna exceeds 6 dBi.
(2) For personal/portable TVBDs, the maximum EIRP shall not exceed 100 milliwatts (20 dBm) with the
following exceptions; Mode II personal/portable TVBDs that do not meet the adjacent channel separation
requirements in § 15.712(a) and Mode I personal/portable TVBDs that operate on available channels
(provided by a Mode II TVBD) that do not meet the adjacent channel separation requirements of §
15.712(a) are limited to a maximum EIRP of 40 milliwatts (16 dBm). These maximum power levels
apply regardless of the number of TV channels on which the device operates.
