Via the DS, a client station can be connected to the outside world, communicating with stations beyond the BSS it is in. But prices will inevitably drop, and availability will then improve. A reservation or a polling procedure, also described below, may be invoked to work in conjunction with the basic CSMA / CA procedure for further enhance collision avoidance. Implement access controls Guest networks may be open, but access to all other WLANs should be constrained using 802.1X Port Access Control, pre-shared keys (PSKs), WEP keys, MAC Access Control Lists
They can however co-exist in a given location. The various standards use a variety of modulation types in various combinations. Frequency bands Radio frequency -- 900 MHz, 2.4 GHz, 5 GHz, and 19 GHz In the years past, 900 MHz and 19 GHz frequency bands were used for wireless LANs. By listening to all the reservation mini slots, a sending station knows which slot it can use to send its data during the next frame.

It sends out its poll frame following the same procedure as the basic CSMA / CA described above, except that the inter frame gap time is now Polling IFS (PIFS). Wireless Network Requirements Document The central station sends a control frame, called poll, to each station following a round-robin pattern. With the back-off, the probability of collision is much reduced.) Data Traversing The frame broadcasts to all stations within the range of the radio transmission power. This is another form of CA and is an option specified in IEEE 802.11.
