Engineers at the VeriWave Inc have expected a problem with the physical layer convergence procedure (PLCP) in 802.11 Wi-Fi nets that could result in packet losses during transmission.
PLCP headers are common convergence protocols used in IP, ATM and other wirelsee nets. In the case of 802.11 wireless nets, a single parity bit in the header can allow header corruption and resulting the network to drop the packet.
As the receiver is blinded for a particular period, thus the receiver will not receive the retransmitted packets. This could in turn seriously affect roaming in larger Wi-Fi networks and will have a greater effect on voice quality rather than jitter.
