x) From 1 January 2017, in Angola, Botswana, Lesotho, Madagascar,
Malawi, Mauritius, Mozambique, Namibia, Democratic Republic of
the Congo, Seychelles, South Africa, Swaziland, Tanzania, Zambia
and Zimbabwe, the frequency bands 157.125-157.325 and 161.725-
161.925 MHz (corresponding to channels: 82, 23, 83, 24, 84, 25, 85, 26
and 86) are designated for digitally modulated emissions.
From 1 January 2017, in China, the frequency bands 157.150 -
157.325 and 161.750 - 161.925 MHz (corresponding to channels: 23,
83, 24, 84, 25, 85, 26 and 86) are designated for digitally modulated
emissions. (WRC-12)
y) These channels may be operated as single or duplex frequency
channels, subject to coordination with affected administrations.
(WRC-12)
z) Until 1 January 2019, these channels maybe used for possible testing
of future AIS applications without causing harmful interference
to, or claiming protection from, existing applications and stations
operating in the fixed and mobile services.
From 1 January 2019, these channels are each split into two simplex
channels. The channels 2027 and 2028 designated as ASM 1 and
ASM 2 are used for application specific messages (ASM) as described
in the most recent version of Recommendation ITU-R M.2092.
(WRC-15)
AAA) From 1 January 2019, the channels 24, 84, 25 and 85 may be merged
in order to form a unique duplex channel with a bandwidth of 100
kHz in order to operate the VDES terrestrial component described in
the most recent version of Recommendation ITU-RM.2092. (WRC-
15)
mm) Transmission on these channels is limited to coast stations. If
permitted by administrations and specified by national regulations,
these channels may be used by ship stations for transmission.
All precautions should be taken to avoid harmful interference to
channels AIS 1, AIS 2, 2027* and 2028*. (WRC-15)
* From 1 January 2019, channel 2027 will be designated ASM 1 and
channel 2028 will be designated ASM 2.
w1) In Regions 1 and 3:
Until 1 January 2017, the frequency bands 157.025-157.175 MHz and
161.625-161.775 MHz (corresponding to channels: 80, 21, 81, 22, 82,
23 and 83) may be used for digitally modulated emissions, subject
to coordination with affected administrations. Stations using these
channels or frequency bands for digitally modulated emissions shall
not cause harmful interference to, or claim pro-tection from, other
stations operating in accordance with Article 5.
