Abstract: The dual mode cellular network has two communication systems with different frame structures and traffic channel protocols. Only one of the protocols supports a forward error correction coding.Preferably the protocol which supports forward error correction coding also supports interleaving, or a combination of a code division, a time division multiple access method and maximum ratio combining diversity. The other one supports a time division multiple access method and switched antenna diversity.
