WLAN Block Relay between Clients: An Infrastructure Basic Service Set is a BSS
with a component called an Access Point (AP). The access point provides a local relay
function for the BSS. All stations in the BSS communicate with the access point and
no longer communicate directly. All frames are relayed between stations by the access
point. This local relay function effectively doubles the range of the IBSS.
WMM: WMM is based on a subset of the IEEE 802.11e WLAN QoS draft standard.
WMM adds prioritized capabilities to Wi-Fi networks and optimizes their
performance when multiple concurring applications, each with different latency and
throughput requirements, compete for network resources. By using WMM, end-user
satisfaction is maintained in a wider variety of environments and traffic conditions.
WMM makes it possible for home network users and enterprise network managers to
decide which data streams are most important and assign them a higher traffic
priority.
WLAN ACK TIMEOUT: ACK frame has to receive ACK timeout frame. If remote
does not receive in specified period, it will be retransmitted.
Modulation Coding Scheme (MCS): MCS is Wireless link data rate for 802.11n.
The throughput/range performance of an AP will depend on its implementation of
coding schemes. MCS includes variables such as the number of spatial streams
modulation, and the data rate on each stream. Radios establishing and maintaining a
link must automatically negotiate the optimum MCS based on channel conditions and
then continuously adjust the selection of MCS as conditions change due to
interference, motion, fading and other events.
Frame Aggregation: Every 802.11 packet, no matter how small, has a fixed amount
of overhead associated with it. Frame Aggregation combines multiple smaller packets
together to form one larger packet. The larger packet can be sent without the overhead
of the individual packets. This technique helps improve the efficiency of the 802.11n
radio allowing more end user data to be sent in a given time.
