Dynamic mapping of ARFCN numbers may be used in order to extend the capability to support more frequencies than with a fixed allocation scheme which is limited to 1024 frequencies. Typically dynamic mapping would be used for ARFCN numbers that have no fixed allocation as described in section 2 but dynamic allocation of other ARFCN numbers is also possible.

Mapping of ARFCN numbers to frequencies may be indicated in System Information type 14, type 15 or Packet System Information Type 8. This mapping may be limited to the actual frequency allocation used by the serving PLMN or additionally to frequencies of other PLMNs in case of co-operation between different PLMNs allowing e.g. handover between those PLMNs.
