Re: [802SEC] 802.18 Draft response to Amtrak FCC Waiver Request
Rich,
Simple question for you - is this letter from the 802.18 group - or will it
be coming from 802? If 802 - please use the liaison template -
https://mentor.ieee.org/802-ec/dcn/17/ec-17-0012-01-00EC-802-liaison-templat
e.docx.
In addition - it is not clear from your motion who the motion is granting
editorial license to.
Please clarify.
Thanks
John

Subject: [802SEC] 802.18 Draft response to Amtrak FCC Waiver Request
Dear EC Members:
Document link included.
Yesterday, in the 802.18 teleconference, we approved an input to the FCC
regarding a request from Amtrak for a waiver of point-to-multipoint transmit
power limits for their trackside networks (TSN) in the Northeast Corridor
(NEC).
The waiver asks that in order to reduce the number of access points needed,
that they be allowed to use the point-to-point transmit power limits to
provide Wi-Fi on the trains. This limit, still 1 Watt conducted, allows the
use of high gain antennas. For every 3 dB of antenna gain over 6 dB, the
conducted power must only be reduced by 1 dB. This allows high power in
narrow beams.
The Amtrak request was not accompanied by any study, simulations or test
data to indicate the impact on Wi-Fi networks in the vicinity of the rail
line. Our ask to the FCC is that they provide us with any Amtrak data on the
impact, and that if they do not have data, that the FCC should require them
to perform the necessary measurements, simulations and/or tests to show that
this trackside network will not become a source of interference to
neighboring Wi-Fi networks.
Please review the draft and provide any comments before final editing and
formatting. I would need the EC to vote to approve on or before the 27th of
February to meet the FCC deadline. It was approved by the members of 802.18
by a vote of 7/0/0. The meeting was announced more than 45 days ago.
