What do ad hoc and infrastructure mode mean?
If all radio cards are sufficiently close together, and there is relatively little traffic, then ad hoc mode allows any card to transmit directly to any other card. This strongly resembles a bus network topology, like ethernet uses. Due to the fact that sometimes not all the radio cards in a zone can hear each other, infrastructure mode designates one card as the “master”. The master then arbiters the channel for all of its “clients”. Communication is then between the master and a client. This kind of resembles how a SCSI bus works. See below for information on IBSS and BSS. 3.7 We need to turn on all the security, don’t we. If you’re referring to 802.11 WEP (Wireless Equivalent Privacy), then no. First, WEP has already been broken. Second, if you encrypt a link, you make it harder for new nodes to join, and the channel key would have to be distributed or made public anyway. Thirdly, you can’t guarantee that your data won’t be routed over un-encrypted links, or that the node owners are
