Sample text

Figure 3-14. Broadcast/multicast data and broadcast management atomic frame exchange Depending on the environment, frames sent to group addresses may have lower service quality because the frames are not acknowledged. Some stations may therefore miss broadcast or multicast traffic, but there is no facility built into the MAC for retransmitting broadcast or multicast frames. 11 standard. This book uses the more common term unicast. Unicast frames must be acknowledged to ensure reliability, which means that a variety of mechanisms can be used to improve efficiency.

Wireless LAN stations may attempt to fragment transmissions so that interference affects only small fragments, not large frames. By immediately reducing the amount of data that can be corrupted by interference, fragmentation may result in a higher effective throughput. Fragmentation takes place when a higher-level packet's length exceeds the fragmentation threshold configured by the network administrator. Fragments all have the same frame sequence number but have ascending fragment numbers to aid in reassembly.

Some vendors set the default fragmentation threshold to be identical to the default RTS/CTS threshold. Figure 3-18. 3 Power-Saving Sequences The most power-hungry components in RF systems are the amplifiers used to boost a signal immediately prior to transmission and to boost the received signal to an intelligible level immediately after its reception. 11 stations can maximize battery life by shutting down the radio transceiver and sleeping periodically. During sleeping periods, access points buffer any unicast frames for sleeping stations.
