INDEXING SCHEME RELATING TO STANDARDS FOR ELECTRIC COMMUNICATION TECHNIQUE ( CLASS H04 )
NOTE
-
This scheme constitutes an non-associated internal scheme for indexing exclusively documents issued by standardisation bodies (herein called standards) for electric communication technique (H04).
As standardisation bodies organize their documents in different ways, the present scheme is subdivided into main groups related to a particular CPC range to allow different indexing approaches.

Scheme index:


Wireless communication standards H04T 2001/00 - H04T2001/999
Standards related to data switching
networks in general H04T 2012/00 - H04T2012/99
Internet standards H04T 2029/00 - H04T2029/99

Collapse
H04T 2001/00
Standards for wireless communication networks
NOTE
-
The indexing codes of this scheme are to be used mainly with classification in CPC subgroups H04W , H04Q7/20 to H04Q7/3883 .
In order to keep the structure adopted by the standardisation bodies considered, a matrix type of scheme is used as indicated below:
- H04T 2001/101 to H04T2001/199 codes are used for information relating to the physical aspects,
e.g. radio resources, core network resources...
- H04T 2001/201 to H04T2001/299 codes are used for information relating to functional aspects, e.g.
physical layer, traffic/transport...
For complete indexing it is mandatory to allocate at least one and preferably only one combination of H04T2001/100 and H04T2001/200 codes to a document.
Searching in this scheme is done by combining the above indicated codes, i.e. H04T2001/100 and H04T2001/200
