APPENDIX A - RF CHANNEL PLANS
AS4000 supports WFA system implementation in various frequency ranges within the
ITU-R and ETSI 2GHz and 3GHz frequency ranges. The specific implementations
currently available operate in frequency bands at 1.8-1.9Ghz, 2.0-2.3GHz, 2.3-2.5GHz
and 3.4-3.6GHz in accordance with the AS4000 “channel plans” shown below.
The RF channelisation is 1.5/3.5/4.0MHz and Frequency Division Duplexing (FDD) is
used. The basic requirement for AS4000 system operation is for a single RF channel
(3.0/3.5MHz go, 3.0/3.5MHz return), with go-return spacing dependant on the channel
plan used.

1.5 MHz channelisation, with 80 MHz Duplex spacing
− RF carriers occupy 3.0MHz, adjacent channel spacing is subject
to cell configuration
− Use of channels 9 & 10 requires contiguous A and D block spectrum.
− In some countries the use of this band may conflict
with other allocations, I.e. GSM-1800, DECT & PHS.
