Module # Working in Infrastructure Mode

 

Infrastructure Mode • In tis mode all te ost com$uters communicate wit eac oter troug access $oint% • Infrastructure mode can be selected using interface $ro&ided wit WLAN card on eac ost com$uter% • 'e network sown in te figure is also known as (asic )er&ice )et *())+%

 

Module , Communicating using A Ad-Hoc d-Hoc Mode

 

 Ad-Hoc Mode • 'is feature allows ost com$uters to communicate wit eac oter witout a&ing an access $oint in te network% • 'is facilit can be cosen b selecting  Ad-Hoc mode on eac ost com$uter troug wireless card interface%

 

Module . DHCP Mode • In DHCP en&ironment eac ost can communicate wit oter ost/s using access $oint as it does in infrastructure mode% • Howe&er in DHCP mode access $oint dnamicall assign IP address to eac ost com$uter connected to it%

 

Module 0 Wired wit Wireless Communication •  A ost com$uter on wireless wireless network network can access anoter com$uter or network facilit suc as $rinter on wired network% • 'is communication is acie&ed troug access $oint wic is connected to te wired network%
