Dual mode communication network
First Claim
Patent Images
1. A dual mode communication network comprising:
- a first communication system using a frame structure and a first traffic channel protocol for transmitting; and
a second communication system using said frame structure and a second traffic channel protocol for transmitting;
wherein only one of said first and second traffic channel protocols uses a forward error correction coding feature and a combination of a code division and a time division multiple access methods and a remaining one of said first and second traffic channel protocols utilizes a time division multiple access method.
