Send packet before sending the actual packet data This setting is useful for networks with many clients With many clients and a high network load there will be many more collisions By lowering the RTS threshold there may be fewer collisions and performance should improve Basically with a faster RTS threshold the system can recover from problems faster RTS packets consume valuable bandwidth however so setting this value too low will limit performance 4 12 What is Beacon Interval In addition to data frames that carry information from higher layers 802 11 includes management and control frames that support data transfer The beacon frame which 15 a type of management frame provides the heartbeat of a wireless LAN enabling 22 USER S MANUAL OF X Micro WLAN 11b ACCESS POINT Version 2 0 EEUU UU t stations to establish and maintain communications in an orderly fashion Beacon Interval represents the amount of time between beacon transmissions Before a station enters power save mode the station needs the beacon interval to know when to wake up to receive the beacon and learn whether there are buffered frames at the access point 4 13 What 1s Preamble Type There are two preamble types defined in IEEE 802 11 specification A long preamble basically gives the decoder more time to process the preamble All 802 11 devices support a long preamble The short preamble is designed to improve efficiency
