Forward error correction is beginning to get some votes on the ipmulticast.com poll, but FEC alone can't give us Reliable IP Multicast. There are several reasons for this:
· Latency - FEC or spread spectrum FEC is going to increase latency during channel changes.
· Conspicuous consumption - In order to support a Radio LAN you have to send a LOT of FEC. Like 10 times the data in a noisy situation. In a radio LAN environment packet out-of-order and packet loss drive consumption beyond acceptable levels.
