Описание
1.1 Applications
The scope of the present document covers the following typical P-MP applications, delivered directly or indirectly, or in
any superimposed transport network layer:
voice;
fax;
voiceband data;
telex;
data up to 64 kbit/s;
ISDN;
Internet Access.
1.2 Frequency bands and channel arrangements
The present document covers Fixed Service bands at 1,5 GHz, 2,2 GHz, 2,4 GHz and 2,6 GHz.
The frequency plans for the 1,5GHz, 2,2GHz and 2,6GHz bands are given in CEPT T/R 13-01 [7] and ITU-R
Recommendation F.1098-1 [20]. For the 2,4 GHz band, the ITU-R Recommendation F.701-2 [8] is applicable.
The present document may cover equipment which uses either Frequency Division Duplexing or Time Division
Duplexing.
NOTE: As with other point-to-multipoint standards, attention should be given to assigning spectrum so as to
allow different systems to operate in adjacent assigned frequencies without unacceptable mutual
interference. This is the responsibility of the regulatory authorities that are advised to note any guidelines
produced by CEPT, particularly those with reference to spectrum where unlike duplex methods are to be
used.
