Quick Q&A With Spectrum Bridge CTO Peter Stanforth
LAKE MARY, FLA.: TVB sent some questions to Peter Stanforth, (right) chief technology officer for Spectrum
Bridge, the company that designed the white-space broadband network recently
launched in Claudville, Va. The system is said to avoid interfering with local
TV station signals through the use of a data base that Spectrum Bridge has
compiled from FCC information.
TVB: I’ve heard SpectrumBridge’s
data base is inaccurate.
Stanforth: The data is taken directly from the
FCC license databases. If someone feels the data is inaccurate it is most
likely due to a different interpretation of the [FCC] current draft rules. With
the next report and order, we anticipate the rules will be clarified and that
this perception of inaccuracy will be retired once and for all. It is also
possible that some data being supplied to the FCC is inaccurate and we encourage
the TV broadcast community to check, verify and correct the data, if needed,
that is contained in the FCC database.
TVB:There
are no white space receivers in the market yet, so what are they using in
Claudville?
Stanforth:
We are using prototype white spaces radios designed to meet the current white
spaces guidelines defined in the FCC Report and Order. The radios are being
deployed under an experimental license granted to Spectrum Bridge by the FCC.
Customer device connectivity is supplied through FCC approved 802.11 WiFi access points.
TVB: Were broadcasters there were included
or consulted?
Stanforth:
Yes we did this as required by the terms and conditions of our experimental license.
TVB:
How is interference to incumbent licensees being monitored?
Stanforth:
We have taken measurements and cannot
identify any interference with incumbent licensees. Through information and
coordination with the FCC and NAB we do not expect any interference impacts.
